ROKU ROKU HC-658 II
Description
Ideal for high-speed milling, drilling and tapping applications, the HC-658 II’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 guarantees a static positioning accuracy of ±0.000060″ and ±0.000020″ repeatability. The HC-658 II 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 is possible via 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 II features a Fanuc 31i-B5 Super High-Speed Processor and Al Contour Control II – A “NANO CNC System” with Intelligent Velocity Control, NANO Interpolation and NANO Smoothing.
