Product characteristics and performance
Features and performance of this machine：Machine is rigidity, high precision, double station（Double stations are used for outer diameters below Φ120, and single stations are used for outer diameters above Φ120）, can be achieved in their respective positions, the precision requirements of the bearing is particularly high, can be a station coarse super - a station fine super (fine super for fine super oil stone) where grinding graphics in more than five edges of the workpiece, super precision after 2-- 500 can change about 40%, roughness (ahead 0.3, After about 0.03).
Super precision swing head adopts stepless speed regulation, no connecting rod servo direct drive oscillation mechanism, oscillation frequency can reach more than 1200 times, there are two kinds of automatic compensation and fixed oil stone device, there are user's choice (user's bearing channel, Raceway has high PT requirements, this super finishing machine is the first choice) when the oil stone compensation pressure is different, there are user's own adjustment, the use of high precision constant temperature filtration system, super finishing effect is good. Workpiece speed, swing head frequency can be adjusted by the man-machine interface, coarse, lapping speed smooth switch by the system automatically completed, the system has a self-diagnosis function, the fault machine will automatically stop and have a text alarm, after the fault is eliminated automatically resume the cycle. The machine must use special special oil and oil stone suitable for this process, the tooling is pre-adjusted outside the machine, simple adjustment, convenient replacement, no scratches inside and outside the diameter of the workpiece.
