• Bearing with permanent grease lubrication connection for bearing sealing air discharge air tool interface hollow shaft encoder, sin/cos 1Vpp, 256 S/R
• 2 channel clamping system for fast tool change, release and clamping cylinder pneumatic, clamping force 13000 N
• Closed cooling jacket for water cooling, 50 bar rotary union, for tool internal cooling and ring with 6 nozzles for external tool cooling
• Tool interface HSK A63 clamping force 18000 N
• Sensors: temperature KTY84, digital sensors status, tool clamped, draw bar in release position, clamped without tool, digital sensor for position releasing piston, signal connections via connectors
• High speeds because there are no mechanical transmission elements
• Smooth running properties as a result of the good balancing
• Good speed stability, good closed loop speed control
• High accuracy of the closed loop position control
• Lower weight, more compact dimensions
• Lower mechanical design costs, as all of the functions are integrated
• High degree of compatibility to the electrical drive system as the spindle, drive converter and NC are engineered and supplied from a single source
• Pneumatic tool clamping and release mechanism
• Closed cooling jacket, internal tool cooling and ring for external tool cooling
• HSK A63 tool interface
• Tool clamped/draw-bar in the release position/clamped without tool sensor
• Permanently connected cable, sensor cable with signal connector, 4.92 ft L power cable with exposed core ends
