Repair And Maintenance Of Bearing Centerless Grinding Machine
MG1020 centerless Grinder Because of high precision, high efficiency, machine tool stability is a very lucrative machine tool, but because the price is high and very few people ask, a new 1020 to 130,000 yuan but an old one is probably only 5 to 60,000 yuan, if you are smart enough, I will teach you to put an old machine tool like new, the same precision stability.

The outer diameter 110 minus 2 wire concentric sleeve, with concentric sleeve to adjust the machine tool's spindle and the casing concentric, but also to ensure that the spindle gap should not be greater than 0.01MM, the wheel shaft with the hand can easily rotate.
Three check dresser and oil cylinder off, with the hand-pull dresser to back and forth freely, must not have the weight, with hand sway around no gap, not with scraping.
Four and check the wheel to handle the same shaft and bushing, and then use concentric sleeve to adjust the axis of the machine tool, to ensure that the transverse gap in 0. No axial drive within 002MM. No abnormal noise after driving.Centerless Grinding Machine
Five because the MG1020 is a hydraulic self-lubricating guide, so the hydraulic system must be fully washable and pressure, please refer to the size of the manual.
