CNC End-face Cylindrical Grinding Machine

B2-GP20/B2-GA20

Watch
Grinding Machine

Introduction

Through import, digestion and absorption of advanced technologies from TOYODA, this CNC cylindrical grinder is developed. As productive machines, they are suitable for large-batched production in the field of automobile, motorcycle, air compressor and bearings as well as small batched production with high accuracy requirement, like military, aviation, and aerospace industry. The mechatronic layout makes the machine conform to human engineering requirements. Large-taper sleeve type hydrostatic/ hydrodynamic spindle is adopted, and linear speed of grinding wheel can reach 60m/s (optional) or 80m/s (CBN wheel). With two-axis linkage movement, the worktable (Z axis) and a wheel head (X axis) are driven by AC servomotors and ball screws. The minimum resolution is 0.1μm and maximum feeding speed is 10m/min. Precise CNC automatic dressing and compensation can be done under the help of diamond dressing device, and various kinds of dressing units are optional for the dressing of external surfaces, conical surfaces, end-face, formed surfaces, arc surfaces and grooves, etc. With CNC system and in-process measuring unit, full-closed loop control of the grinding process can be completed. The CNC system provides all-around controlling functions including grinding program changes, work-piece quality control, machine condition monitoring, fault self-diagnostics, and abnormal alarm, etc.
