5 High speed package consisting off: - rapid traverse 60 m/min in x-, y- and z-axes. - Spindle speed range: m 1 - Chip-to-chip-time appr. 4,0 s - Thermo drive with indirect path measuring system Remark: With normal conditions the machine does not have to be anchored to the floor. (For slippery floors we recommend anchoring.) Production package with high pressure pump (HSK A 63) consisting of: - Chip conveyor (scratch band) instead of coolant equipment with chip container discharge height mm, discharge to the left, tank capacity 180 l, lift pump with 200 l/min. at 1,5 bar, incl. bed flushing system - Coolant equipment TPF 350 S / 900 tank capacity 1200 l, pump capacity 200 l/min at 2,0 bar high pressure pump capacity 20 l/min at 30 bar coolant filtration for high pressure and flood coolant with vacuum rotation filter VRF 250, filtration 50 µm nominal and mud remover in clean water tank. - Machine preparation for through tool coolant system including: sealing system in the DIN HSK A63* collet coolant distributor installed at the main spindle drive coolant leakage sensor implemented mud flap in the high pressure piping and flow control switch solenoid valve, controlled via machine program * At HSK we recommend for tool holders the use of our patented coolant tube with sieve. Advantage: - Decrease of the clogging in the internal coolant cannel. - Reduction of the wear at the O-ring seal in the collet. Wash gun Mill E.doc Seite 5 von

6 Exhaust fan with air cleaner exhaust capacity 800 m³/h Smoke and gases that arise during the processing are not filtered by this unit. In this case we recommend the connection to a central exhaust fan. Glass scales Over pressured in all axis Y, Z = 500 x 550 mm Probe for automatic measuring in the machine Renishaw - probe - package OMP 40-2LS for part measuring and automatic machine compensation, - probe with optical contact modul and tool taper suitable for machine spindle - tracing pin 58 mm with ruby ball dia. 4 mm - infrared sensor OMI-2C - process oriented measuring - software for measuring cycles and strategy program Remark: For the carrying out of machine compensations with probe a suitable reference surface at the machine or at the fixture or an optional gauge block (VCS ) are necessary. CHIRON Kinematics Fit with measuring ball To ensure best milling results 5-axis-machines need calibration from time to time. This option provides automatic measuring of the machine kinematics by sampling a measuring ball in the working area and subsequent adjustment of the machine-transformation parameters for rotation and swivel axes. For machines with 2 axis rotary table or swivel head with rotary table. Incl. option for NC control and calibrated measuring ball with holder. Precondition: spindle probe and 5-axes-machining at machines with Siemens or Fanuc control Network connection: RPC with TDI Mill E.doc Seite 6 von
