Compact, high accuracy and rigidity
This machine has been developed to master the standard cylindrical grinding machine. All sliding guideways are scraped by our skilled employees to provide high precision and long service life. We ensure that the grinding wheel axis' infeed accuracy and repeatability for 10 years.
Workpiece fixing method:
①grinding between centers
②scroll chuck
③collet chuck
Accurate infeed and following performance for precision cylindrical grinding
Back/Forward axis has a pulser handwheel as standard equipment to change feeding amount, and its Min. infeeding amount is 0.00005mm. Right/Left axis mounts a precision ball screw to feed at the 0.0001mm level.
Our original workhead spindle enables high roundness accuracy
The workhead spindle mounts a ball bearing for high rigidity and improving maintainability. Our original assembly system enables machining at the 0.0001mm level. A servo motor of rotary drive allows stepless rotary adjustment.
L/R axis high accuracy positioning as a standard feature
This versatile machine mounts L/R inversion teaching function to achieve high accuracy in L/R axis' positioning. It is easy to operate, just press teaching buttons at R/L inversion positions to achieve submicron level of positioning. The teaching function is effective during manual handle operation.
Advantages of our original internal grinding unit
Our optional internal grinding unit mounts independent drive mechanism. The unit with swiveling shaft allows oscillation of internal grinding spindle. This mechanism enables one chuck machining of high accuracy cylindricity and concentricity with ease. Even there are workpieces under such conditions, efficient machining can be done without compensation every time.
Point① Internal grinding axial runout
Point② Internal grinding with independent driving unit
Compensation of outer cylindricity and internal cylindricity errors are possible.
