HC-878
The
HC-878'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 ±0.000078”
and ±0.000039” repeatability.
The HC-878 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-878 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. |
