3 Face Mill for Heavy Milling MSRSType Significantly Improved Metal Removal Rate.R. +9 R.R. 9 (ø80) 5 (more than ø00) Face Mill for Heavy Milling Lead angle: 75 degrees MSRStype MSRS Revolutionizes Heavy Milling (maximum depth of cut is 2mm) Large depth of cut and high feed rate achieve high efficiency machining. Recommended depth of cut: 5 to 0mm. Wide lands strengthen edges. Square Insert MSR Facemill Conventional tools Unique design allows suppressed chattering and low cutting force Comparison of cutting force (radial force) The MSRS suppresses chattering since less up force is created reducing potential to lift the work piece into the cutter. Notched 2mm Large wiper edges achieve high feed rate. (Max.D.O.C. ) 5mm CornerR=.2mm 8mm 6.35mm Inserts are strengthened with 6.35mm width. Notched insert reduces cutting force, chattering and enables efficient machining.

11 MSR Type MSR Cutter Q & Q. What is the most recommended cutting condition for MSR? Q.5 Can be applied for cast iron machining?.,, Large larger cutting depth and smaller cutting width In case of MSR00R2 e.g)loadmeter 20% e.g)loadmeter 90% pass 2 pass 3 pass ap X ae: 5 X 75mm 3 pass 2 pass ap X ae: 5 X 25mm pass.5 YES There is a case of cast iron machining at 800cc/min removal rate. Basically machinability is better than steel and there is no problem. Recommended cutting condition fz=0.3mm/t * In case necessity of wear resistant grade, use PR905(PR830) Q.6 What is the tool life? Q.2.2 Q.3.3 Required equipments for MSR? Maximum spindle revolution should be lower than 000min. BT50 or larger *MSR is not only for Double column machining center The reason why not recommended for high RPM spindle machine is its less toruque. *lthough MSR works with BT0 shank, maximum available fz is about 0.mm/tooth. What is the points to remember in case of less power machine? Do not use large size cutter Dia.63 or Dia.80mm is recommended. Set up conditions to get the largest available torque by checking torque curve of the machine. Tried under condition of, enough torque was not gained because of high gear. In this case, it has to be prioritized using Vc which can exert enough torque as Vc=20m/min. Please increase cutting speed and decrease feed ratio. *Machine torque curve will be prioritized..6 Q.7.7 Chip weight: 700kg/Corner (Result by PR6) Machining time: 90min (calculated value) Machining distance: 65m (calculated value) How great 000cc/min? bout 7.8kg chips removed per minute Tool life time = 700kg (Chip weight) 7.8kg (Chip evacuation amount per min) = 90min Machining distance= 90min (Time by the end of tool life) x 77mm/min (Table feed ratio per min)=65m * In case of, ap x tae: 20x70mm, Vf=77mm/min * Tool: MSR00R2 (6 flutes) How to reduce chattering. If chattering is caused under machining environment, following condition is recommended. In case of chattering Reduce cutting speed and increase feed rate Q.. In case of unstable workpiece Decrease feed ratio at start cutting workpiece In case of general steel Vc=80m/min fz=0.25mm/t In case of cat iron Vc=80m/min fz=0.35mm/t * lmost all cases f moving workpiece happens when start machining Effective for increasing cutting speed and decrease feed ratio, Vc=200m/min,fz=0.5mm/t 0

16 MSRS Type Face Mill Q& Q What is the recommended radial width of cut (ae)? Recommendation is 70 to 80% of cutter diameter. Q2 Why is the MSRS cutting edge inclination angle 75 degree? 2 Type with 5 degree cutting edge angle suppresses the impact of cutting into workpiece, but has bigger radial force. Meanwhile, type with 90 degree cutting edge angle has smaller radial force, but bigger impact on cutting into workpiece. The MSRS cutter with 75 degree cutting edge angle generates small radial force even on large depth of cut, as well as less impact on approaching, and, due to its wellbalanced design, enables smooth machining. The amount of chip evacuation of MSRS Type is increased much more than conventional tools.
