Startng and Stoppng the Man Spndle ) Only use the correct voltage as ndcated on the ratng plate on the top of the headstock (Fg ). ) Turn the power on by turnng the key to the rght (Fg -). (The key can not be pulled out when t s the on poston.) 3) Turn the rotaton drecton knob to the desred poston (forward or reverse). 4) Press the ON button to begn operaton (Fg -). 5) When changng the drecton of rotaton, check frst that the machne has completely stopped movng. Turn the drecton knob to the desred drecton and press the ON button to restart the lathe. 6) Before leavng the machne unattended, press the OFF button and make sure the machne has completely stopped movng. Turn the power off by turnng the key to the left. Ths key must NOT be left nserted n the machne. It s mportant that the key s kept on the machne user or out of reach of unauthorzed users (such as chldren) when the machne s not n use. Please avod use by any unauthorzed users. (Use Stop L-3 Normal utmost cauton n the storage of ths key.) Fnally, be sure to unplug the machne before leavng t unattended. Reverse. Man Spndle Speed () Adjustng the Speed The ML-360 s capable of 6 spndle speeds (Fg. 3-). Poston A s for hgh speeds and poston B s for low speeds. To reposton the belt (K-), stop the man spndle and open the pulley guard. Loosen bolt () whch s to the rght of the counter pulley (b) so that the tenson pulley () can be manually adjusted between postons A and B (Fg. 3-). Then place tenson pulley () n a poston between A A B, and set the belt from the man spndle pulley (c) to the motor pulley for the speed desred. *For hgh speeds, the bolt runs from man spndle pulley (c) to motor pulley (a); for low speeds, the bolt runs from man spndle pulley (c) to counter pulley (b). Dagram 3- shows the settng for low speed (B) usage. When the belt s set on the pulleys, tghten bolt (). Then move the tenson pulley () to poston A f usng hgh speeds, or to poston B f usng low speeds.

9 () Selectng the Proper Man Spndle Speed The man spndle speed s determned by the workpece materal and dameter. Nonferrous metals, such as alumnum or brass, are machned at hgher speeds than ferrous metals, such as steel or cast ron. Smaller dameters requre hgher speeds. If the motor should stall, or the belt come loose durng operaton, turn the machne off mmedately. Move the tool away from the workpece before resumng machnng wth a more shallow cut. (3) Workpece and Man Spndle rpm Man Spndle rpm s determned by the cuttng speed of the tool pont. Ths s calculated by how many nches per mnute the tool cuts nto the workpece. Man spndle rpm N = 36 V / n D t: p = 3.4 V : cuttng speed (n/mn.) D : dameter of workpece (n) N Man spndle rpm For Example: For an alumnum alloy materal wth a dameter of 3/4n (cuttng speed 55yd/mn.), the man spndle rpm s calculated as follows: N = 36x55 = 980 / x 3/4 840 (rpm) Spndle Speeds Number of revoluton per mnute.

Carrage Handwheel (g) feeds the carrage longtudnally. Handwheel (a) feeds the cross slde across the bed. Screw (c) s used to adjust the tghtness of the cross slde gb strp. Bolt (d) locks the cross slde, and bolt (e) locks the carrage to the lathe bed (Fg 5, 6). -4- (5)

10 4. Talstock To slde the tals to ck along the lathe bed ways longtudnally, loosen bolt (h). peed the talstock spndle wth handwheel (), and lock the talstock spndle by tghtenng bolt (k). A dead center, lve center, or drll chuck can be ftted to the talstock spndle. Before fttng these accessores, t s essental that the tapered arbor of the accessory and the nternal taper n the talstock spndle are absolutely clean and free of grease. (6) Feed the talstock spndle forward by rotatng the talstock spndle feed handwheel (). Frmly push n the accessory. The accessory s automatcally ejected when the spndle s retracted to ts fullest extent. The spndle and handwheel calbraton (j) s a useful reference for drllng and smlar operatons n the lathe (Fg 6). 5. Handwheel Calbraton Each handwheels has a calbrated cone (I) whch can be re-set zero as a reference. After takng a roughng cut, determne the remanng depth of cut requred to fnsh the workpece. Set the calbrated cone (I) to the zero poston whle holdng the handwheel (a) so t does not move (Fg 7). Ths makes t easy to keep track of how much has been removed from the workpece and how much more needs to be cut. (7) One revoluton of the handwheel s equvalent to.050 n. feed. The short graduatons are each.00 n. and the long graduatons each represent.005 n. -5-

11 [] «Holdng the Workpccc» There are several ways of holdng the workpece, dependng upon ts shape and sze. As a general rule, the workpece s held wth a chuck. Longer peces can be held between man spndle and talstock spndle centers. Irregular shapes can be secured to the face plate. For extreme accuracy or repettve cuttng of small parts, the collet chuck s recommended.. Holdng Wth a Chuck The followng types of chucks are avalable for your ML jaw Unversal Chuck -4-jaw Independent Chuck -Collet Chuck () 3-jaw Unversal Chuck (No.350) The jaws of the 3-jaw unversal chuck are opend and closed by turnng the chuck key (Photo 8). The jaws move smultaneously and center the workpece automatcally as they close. Please refer to Fgures 9 and 0 for the recommended dmensons of round or hexagonal workpece to be held n the 3-jaw chuck. [jpt r ].36"*.574"0 0.55'* *In the nterest of safety, the recommended chuck capacty should not be exceeded. Normal Jaw (9) A. Fttng the Jaws a) Normal Jaw Fnng Turnng the chuck key clockwse wll cause the scroll n the chuck to rotate counterclockwse. Wth the jaws removed, turn the.377"* key untl the end of the scroll thread appears n jaw slot No.l. - Then turn back slghtly and nsert jaw so that the jaw comes n contact wth the scroll. Turn the key farther clockwse to engage jaw wth the scroll thread. Next, the end of the scroll Reversed Jaw thread wll appear n jaw slot No.3. Follow the same procedures (0) to ft jaws and 3. It s mportant to nsert the jaws n order from to 3, so as to make the jaws meet evenly at the center. -6-

12 b) Reversed Jaw Fnng Wth all jaws removed from the chuck, follow the same procedure as normal jaw fttng to ft the set of reversed jaws n order from to 3 (Fg. ). Scroll cut c () 4-Jaw Independent Chuck (No.350) () The 4-Jaw ndependent chuck s used to grp round, square, rectangular, or rregularly shaped workpeces. Recommended maxmum workpece dmensons are gven n Fgures and 3. In the nterest of safety, these dmensons should not be exceeded. Each of the 4 jaws s operated ndependently. Therefore, the jaws do not automatcally center the workpece. A. Jaw Reversng Remove the jaws wth the chuck key provded, and reft the reversed jaws onto the chuck. There s no specfc order n 0.669" * whch the reversed jaws must be attached. B. Centerng the Workpece To hold the workpece wth the 4-Jaw ndependent chuck, the 4 jaws must each be brought nto poston and tghtened evenly. A surface gauge or cuttng tool ftted to the tool post s convenent reference for ths procedure. Normal Jaw () a) Centerng ) Open the jaws wth the chuck key and hold the workpece n approxmately the correct poston. Adjust two opposte jaws to grp the work lghtly ' * Reversed Jaw (3) -7-

13 ) Close the other jaws alternately to grp the workpece as unformly as possble. Surface gauge 3) For fnal centerng, set a surface gauge (Photo 4) or cuttng tool tp (Photo 5) close to a reference mark on the face of the workpece. 4)Rotate the check and workpece by hand to check the reference mark. When the fnal poston s determned, tghten the jaws evenly. (3) Fttng and Removng the Chuck A. Fttng the Chuck ) Clean the end of the man spndle and back of the chuck thoroughly. ) Place the chuck on the end of the man spndle wth the shoulder on the man spndle seated evenly n the undercut on the back of the chuck. 3) Insert the socket head bolts and tghten them evenly to secure the chuck (Photo 6). 4) When fttng the 4-jaw ndependent chuck, tghten the four bolts evenly n dagonal order. B. Removng the Chuck To remove the chuck, reverse the "fttng" procedure. Place a safety plate of plywood or some soft materal on the lathe bed to protect t n case the chuck s accdentally dropped(photo 6). (4) Collet Chuck (No.3509) A collet s used to grp small dameter workpece wth great accuracy. The Collet sets (No.3530) ncludes standard round collet szes: /8, 3/6,/4, 5/6,3/8, and /". It also ncludes a ff tt t t f f ff blank collet whch you may fnsh to any requred sze (Photo 7). -8-

14 A. Fnng the Collet Chuck The collet chuck s ftted to the end of the man spndle and conssts of a collet holder, a collet nut, and nterchangeable collets. A dal gauge, or ndcator, s requred for centerng the collet chuck. a) Fttng the Collet Chuck ) Ft the collet holder to the end of the man spndle by lghtly screwng n the Allen socket head bolts (Photo 9). ) Use the dal gauge on the outsde of the collet holder to center t. When the collet holder s properly centered, tghten the socket head bolts frmly (Photo 0). 3) Insert the requred collet nto the collet holder (Photo ). 4) Screw n the collet nut just enough to prevent the collet from rattlng around (Photo ). Do not tghten the collet chuck wthout a workpece n t, as ths wll cause the collet to be dstorted. -9-

15 B. Holdng the Workpece Insert the workpece nto the collet. Insert one of the lockng bars nto the hole n the collet holder, and the other bar n the hole n the collet nut. Turn the bar n the holder counter clockwse and the bar n the nut clockwse to tghten.. Holdng wth Centers When machnng a long workpece, t s best to mount t between centers n the man spndle and talstock spndle. The tps of the center have a 60 concal shape. () Talstock Spndle Dead Center (No.3505) The dead center fts nto the nternal taper of the talstock spndle. When the workpece s rotatng, t s mportant to keep the tp of the center and the center hole of the workpece lubrcated constantly to avod overheatng due to frcton (Photo 3). () Man Spndle Dead Center (No.3505) Dead center No also fts the nternal taper of the man spndle. When the dead center s used n the man spndle, t dose not have to be lubrcated, because t rotates wht the workpece. (3) Lve Center (No.3507) The lve center fts nto the nternal taper of the talstock spndle. The tp of the lve center rotates wth the workpece on two ball bearngs. Ths elmnates frcton between the workpece and the center and makes lubrcaton unnecessary (Photo 4). -0-

16 (4) Fttng the Centers It s mportant to keep the external tapers of the centers and the nternal tapers of the spndles clean and free of grease. Wpe all contactng surfaces to clear them of chps, drt, and lubrcants. A. Fttng a Tal Spndle Center Sngle center machnng s the process of machnng a workpece whch s held between the chuck on the man spndle and a lve or dead center on the talstock spndle. The end of the workpece that s held by a center must be center drlled. B. Fttng Two Centers Machnng between two centers s the process of machnng when the workpece s mounted between one center on the man spndle and another on the talstock spndle. For ths process, the workpece must have been center drlled on both ends. a) Fttng the Centers ) Clean the nternal taper of the man and talstock spndles thoroughly. ) Ft the dead center nto the man spndle. Ft the rotaton stopper bolt (Fg. 5). 3) Ft the dead/lve center to the talstock spndle, ensurng that both surfaces are clean. 4) Mount the lathe dog (No. 3404) on the workpece (Fg. 6). IM) --

17 5) Place the end of the workpece (wth lathe dog attached) aganst the man spndle dead center (Fg. 7). 6) Support the other end of the workpece wth the talstock spndle center. Be sure that there s no backlash (Fg. 8). * The dead center s recommended for more precse cuttng. Rotaton stopper bolt However, the dead center must be well lubrcated so that the center hole s not damaged. b) Removng the Centers Refer to 'Talstock* on page 5 regardng the automatc ejecton of the accessory from the talstock spndle. The lve center and the dead center are both removed n the same manner. To remove the dead center from the man spndle, nsert a soft metal bar (/ n. da. or smaller) nto the man spndle from outer end. Gently tap out the center. Always hold one hand open under the center when removng t, so that t does not fall onto the bed (Photo 9). --

18 [3] «Cuttng Tools». Types of Cuttng Tools There are 8 types of cuttng tools specally desgned for your Mn Lathe. These tools are ready-ground for mmedate use. From tme to tme, t may become necessary to regrnd the tool to sharpen t, or to reshape t for a certan type of work. Tools can be ground usng a hgh qualty bench grnder ftted wth the correct grndng wheel (Refer to Regrndng Fgs. 30~34) Saka cuttng tools are all made from Hgh Speed Tool Steel. ) Rght-hand fnshng tool (No. 3450) For cylndrcal turnng and facng cuts.

When borng wth ether No or No borng tool, the hole must be started wth a drll or by some other means. The borng bars are used to enlarge exstng holes. -3-

19 6) Cut Off Tool (No.3055) Ths tool s used for cuttng off a part of the workpece or for cuttng grooves n a workpece. It can also be ground for a partcular applcaton, e.g., cuttng an external thread. The tool s used wth the cut off tool holder (No. 346). Three peces are ncluded n each set (Fg. 35). 7) Cut Off Tool Holder (No.346) (M) The flat tool holder s used to hold the cut off tool (No.3055). Workpbtt (Photo 36). 8) Internal threadng tool (No.3056) Ths tool s used for cuttng nternal threads (Fg. 37) 9) Unground tool (No.3060) A square bt whch can be ground to sut your specfc needs (Fg.,.966" 7] c (38) 38). () Fttng the Cuttng Tools to the Tool Post The cuttng tool must be securely mounted n the tool post. It must be free of movement or vbraton to perform accurate machnng. Note the followng ponts: ) The overhang of the tool from the tool post surface must not exceed.5 tmes the thckness of the tool shank. Tools havng excessve overhang may cause an naccurate cut, or damage may result to the tool. ) The pont of the cuttng tool must be algned wth the center heght or axs of the lathe, A\\gn the tp of the tool wth the tp of the dead center ftted n the man or talstock spndle (Fg. 39). To attan the best tool poston, t may be necessary to rase the tool by nsertng a shm under the tool shank. The shm should have the same dmensons as the tool shank (Fg. 40). -4- Shm Correct

20 3) To secure the tool, tghten the two clampng bolts wth the Allen wrench. The bolts should be tghtened alternately and evenly. *The tool may shft down slghtly when tghtenng the bolt.

[4] «Machnng» Generally, machnng s the process of rotatng the workpece, applyng the tool to t, and adjustng the feed to remove metal from the workpece. However, there are many dfferent ways of machnng, dependng upon the desred end product. * Be careful not to touch the chuck, workpece, or other rotatng parts whle the lathe s runnng.. Cylndrcal Turnng Ths s the most basc method of machnng, and nvolves cuttng the outsde of the workpece. ) Mount the workpece n a chuck, on the face plate, or between lathe centers. ) Ft the rght-hand fnshng tool or roughng tool n the tool post. 3) Select the requred spndle speed whch s determned by the type of metal and the dameter of the workpece. Open the pulley cover, and poston the belts accordng to the speed requred. 4) Advance the cross slde to set the requred depth of cut, and start the man spndle. * Frst, make a roughng cut leavng about n. oversze. Check the dmensons of the workpece to determne the remanng cut. Resume machnng whle occasonally checkng the dmensons untl the desred sze has been attaned. * Generally, the rght-hand fnshng tool (No.3450) s used for fnshng cuts and the roughng tool (No.345) for prelmnary cuts. -5-

21 * When machnng a long workpece, t s very dangerous to work wth the unmachned end protrudng from the headstock man spndle (Note arrow n Fg. 4). Cut the workpece to a shorter length to avod excessve protruson. L-. t. Facng Cuts Ths s the process of machnng the surface of the workpece (4) that s at a rght angle to the man spndle. ) Ft the rght-hand fnshng tool (No,3450) to the tool post, algnng t wth the center heght. Tghten the tool post after checkng the tool angle aganst the workpece (Fg. 43). ) Move the tool nto cuttng poston by adjustng the carrage longtudnally on the lathe bed. 3) Turn on the motor and commence cuttng from the outer edge to the center of the workpece by advancng the cross slde. 3. Step Turnng Decde the depth of the step and then follow the procedures for cylndrcal turnng (Photo 44). ) Ft the rght-handed fnshng tool (No.3450) to the tool post. ) Feed the carrage so that the cuttng tool pont comes n contact wth the outer edge of the workpece. Set the calbrated cone of each handwheel to zero (for settng procedure refer to 'Handwheel Calbraton', page 5). * Repeat cylndrcal and counterface cuttng alternately untl the workpece s cut to the requred dmensons. When a deep cut s requred, t wll be necessary to repeat the operaton several tmes. -6-

22 4. Cut Off Ths s the process of cut off a part of the workpece by feedng the cuttng tool at a rght angle to the center lne of the man spndle. The Cut Off Tool (No.3055) s ftted to the tool post wth the cut off tool holder (No.346) (Fg.45). () The Cut Off Procedure ) The cut off should be made as close as possble to the chuck. If the cut-off poston s too far from the chuck, chatter may result and damage the tool or the workpece. ) Algn the pont of the cut off tool wth the center heght of the lathe. Set t at an exact rght angle to the center lne of the man spndle (Fg. 45). 3) Select a lower speed than for cylndrcal turnng. Adjust the belt postons accordngly. 4) Feed the tool to the cut off poston. 5) Turn on the motor and carefully feed the tool nto the workpece. * Decrease the feed rate at the center of the workpece, especally as you near the cut off pont. Ths s the most crucal part of the cut off process. * Use plenty of lubrcant ol n order to protect the cuttng tool from damage. 5. Center Drllng and Centerng Centerng s a very mportant technque for accurate machnng. Center drllng the locaton of any hole makes t easer to drll the hole more precsely. The maxmum permssble overhang of the workpece from the chuck (3-jaw, 4-jaw, or collet) s generally three tmes the dameter of the workpece. Longer workpeces must be supported by a center n the talstock spndle. () Center The center hole s extremely mportant, as t becomes the base of other machnng processes. Therefore, the utmost care s requred n machnng the most exact and accurate center hole (Fg. 46). Center drlls (No.307) are avalable n szes of.0,.5, and.0 mm dameter at the tp.

Move the talstock close to the workpece and lock t n poston. 5) Set the approprate man spndle speed. 6) Turn the motor on and feed the drll wth the talstock spndle feed handwhcel. * The center drll tp s especally susceptble to damage. It must be fed n slowly usng plenty of cuttng ol. 6. Borng Borng s the process of enlargng a hole made by a drll or other means to a specfc sze (Photo 47). * In the case that the workpece does not already have a hole n t, one must be made by drllng. () The Borng Procedure ) Mount the workpece n the chuck. ) Ft the borng tool to the tool post usng the adaptor (No. 3459). Algn the pont of the borng tool wth the center heght of the lathe. 3) Select the man spndle speed, and adjust the belts. 4) Turn the motor on and feed the tool. * Due to the length of the borng tool, t may chatter unless the correct (slow) feed rate s used. * Be sure to keep the workpece free of chps and use plenty of cuttng ol for better borng. -8-

Refer to pages 8, 9, and for fttng procedures. ) Determne the most convenent poston for the crank (f) (.e. decde on whch sde you want to attach the crank). Loosen the screws (g) and set the worm shaft assembly (A) to the sde you prefer. *It s mportant to adjust the backlash of the man spndle worm wheel before tghtenng the worm shaft assembly wth screws (9) * Backlash adjustment s an ndspensable part of operatng the crcular dvdng table. The way the worm meshes wth the worm wheel s changed by a sngle turn of the worm shaft assembly (a). Wth two fngers, turn the worm shaft assembly untl the wheel and assembly mesh lghtly. Then secure t n poston wth the screw (g) (Fg. 5). 3) Select the approprate dvdng plate for the requred dvson (refer to Table ) and ft as follows VVorm wheel HIS)

44 Remove the thumb nut () and n order, pull out the crank (f), spacer A (j), wave washer (k), spacer B (I), sector B (m), and sector A (n). Remove the flat head screws that hold the dvdng plate to the worm shaft shoulder and change the dvdng plate. Adjust the space between the stems of the sectors (explaned on Page 40) and re-attach the fttngs n the reverse order to whch they were removed (Fg. 6). 3) Next we wll prepare for the actual dvdng operaton. The example gven below llustrates how to obtan 5 dvsons. nt) Wth crank revoluton n and dvson N, and the worm gear rate at /40, the relatonshp between n and N can be expressed as ' n = 40/N () Usng formula (), f the dvson s 5, the crank revoluton becomes : n = 40/5 =40/5 () Ths means that the requred crank feed s revolutons and 0 holes of a 5-hole dvdng plate. However, snce there s not a 5-hole plate, the number ( & 0/5) must be recalculated to correspond wth the dvdng plates avalable. The followng are the possble substtutons: A 0/5 = ( A /3) = A 8/7 ( revolutons * 8 holes of a 7-hole plate) A 0/5 = A /33 ( revolutons + holes of a 33-hole plate) A 0/5 = A 4/36 etc... Refer to secton 3 above to ft the 4 A 7 hole plate to the 4 hole crcle -39- Set screw 7- hole crcle 7) Set screw man spndle of the dvdng table (Fg. 7). Loosen the screw on Sector A and poston the sectors so that 9 (8+ ) holes appear between the stems of Sector A and Sector B. Then tghten the screw (Fg. 8). Sector B HID

45 Don't forget that you must always add an extra hole to the requred number. In ths example, the requred number s 8; the clamp pn at the tp of the crank must be placed n hole number 7 - hole crcle 9 n order for the crank to move 8 spaces. Set the space between Sectors A and B before re-attachng spacer B, the wavy washer, spacer A, the crank, the crank screw, etc, Fnally, set the clamp pn (p) so that t fts nto one of the holes of the 7-hole plate, and tghten the clamp screw () frmly. Ths completes the preparaton for the dvdng operaton (Fg. 9). Crank (MB) 5) Before begnnng the dvdng operaton, loosen the rotaton stopper bolts (r) on the crcular dvdng table (Photo 0). Pull the crank out whle rotatng t, and ft the crank pn nto any hole between the stems of Sector A and Sector B. Turn the unt of Sectors A and B to the rght, and stop when the stem of Sector A touches the crank pn. Ths becomes the startng poston. Whle pullng out, turn the crank revolutons to the rght and stop at the startng hole. Scctor B Feed the crank pn 8 holes (from the above calculaton) to the rght untl the pn comes n contact wth the stem of Sector B. Tghten the rotaton stopper bolts and begn cuttng. To prepare for another dvdng operaton, loosen the rotaton stopper bolts and turn the unt of Sectors A and B to the rght Sector A turnng to the rght untl the stem of Sector A touches the crank pn. Then repeat the whole procedure (Fg. ). feedng n the opposte drecton, pay attenton to the backlash between the worm shaft and the worm wheel. Feed to the left past the necessary pont, and then turn back to the rght to ft the crank pn n the necessary hole. -40-
