Features:Hardened and precision ground guide-ways are Turcite-B coated. Extra wide box ways design increase contact surface area for higher stability, faster positioning and heavier cutting.The multi-speed spindle adopts top quality German-built Z.F. dual section gear box. Fully sealed immersion type lubrication with oil chiller circulates coolant and keeps the machine running cool even at 10,000 rpm. (Optional: KMV-8VC).The spindle runs on high precision taper roller bearings which allow for any type of heavy duty cutting without vibration.The Z axis is balanced with Nitrogen in conjunction with pneumatic Nitrogen cushioning of the headstock for automatic balancing during vertical motion. Perfectly level and smooth action eradicates vibration. (Optional: KMV-8VC)Lubricant is pressure fed at a volumetric ratio for even distribution at all critical points for optimal lubrication.All three axes employ C3 grade high precision ball screws, each with dual pretension nuts and internal cooling ducts with preloaded support at both ends.The spindle and ball screws at all three axes are cooled by re-circulated oil which passes through an oil chiller, dispelling heat deformation (optional: KMV-8VC).The disc type system is fast and compact. Arm movement is smooth with excellent repeatability. Tool change time is 2.5 seconds (BT40).Compatible with a variety of CNC control systems including Fanuc, Mitsubishi, Siemens, Heidenhain or Italian Selca..Sizes available from 820 × 600× 600mm to 1600 × 815 × 815mm ( X × Y × Z ).
