NCCG Machine NPG-80V


Mass production is also possible with the use of an optional automatic transfer machine.

While general-purpose machines require skill in setup, the NC-controlled automatic compensation function makes spherical surface machining easy.

NC control allows automatic setting of machining conditions by inputting information on the target workpiece and grinding wheel. In addition, automatic compensation functions (convexity correction and Δh correction) allow processing conditions to be corrected simply by inputting the measured values of test-cut workpieces.
Grinding wheel feed function is provided according to the number of times the grinding wheel is processed to compensate for wheel wear.
The use of an optional automatic transporter enables automatic feeding of workpieces and continuous processing of workpieces.
A chamfering axis can be attached as an option.
