This heavy-duty series integrate NC control, AC servo motor, and solenoid valve hydraulic system into one rigid mechanism. Together with the centralized user -friendly control system, our heavy-duty series is capable of executing all types of grinding tasks with the greatest efficiency.
Heavy duty column type surface grinder
3468 ~ 34188 AHD / PNC
Enhanced net type double wall structure ensures machine solidity and grinding precision
Hydraulic weight balancing assists reliving the loads of vertical feed ball-screw. It assures the sensitivity and accuracy of vertical feed, as well as extends the life-span of servo motor & vertical ball-screw.
Spindle & Motor set
High precision in-house assembled cartridge type spindle set uses 6 super precision CP4 grade angular ball bearings, sealed with permanent lubrication. This structural superiority empowers the spindle to grind with low noise, low heat rise, and high precision
V3 grade motor is integrated with spindle set via couplings for direct transmission, to obtain maximum torque and reduce vibration
Control system (AHD type)
Numerical Control system that utilizes AC servo motor on vertical feed
Encoders equipped on servo motor and high precision ball-screw ensure superior sensitivity and accuracy of wheel positioning
Automatic cross feed travel limits can be set via control panel
Multiple vertical feed modes: A. Automatic B. Manual C. Micron pulse generator
