Ideal for High-Speed Milling, Drilling and Tapping Applications
The HC-658's high rigidity, bridge-type monoblock structure allows high-speed, high-precision machining while the minimized distance between guide surface and spindle center provides greater stability.The high rigidity bed with ideal rib distribution has been designed by computer analysis with a guaranteed static positioning accuracy of ±0.000060” and ±0.000020” repeatability.

The HC-658 is capable of a wide range (200 - 32,000 RPM) using a grease-packed spindle and a long-life AC motor. High-speed direct hard milling can be done by dry or semi-dry oil-mist systems. New HSK-E40 holder achieves six times higher clamping force than a regular BT shank while Dual Balance Cylinders reduce load for the ball screw and servo motor.

The HC-658 features a Fanuc 31i-A5 Super High-Speed Processor and Al Contour Control II – A “NANO CNC System” with Intelligent Velocity Control, NANO Interpolation and NANO Smoothing. The look ahead has been expanded to 1,000 blocks.
