What are the main components of the general double-end grinder?


The machining accuracy that can be achieved by the double-end grinder can be processed by workpieces with high requirements on the parallelism of the upper and lower surfaces, dimensional accuracy and surface roughness of the machined parts (such as bearing inner ring, oil pump gear bearing, air conditioning compressor, gear, car parts, hydraulic parts, difficult-to-process data and other professional parts, etc.).

 

The difference between it and the general surface grinding machine is that it is not fixed by magnetism, but the upper and lower planes of the workpiece are parallel grinding together. That is to say, regardless of whether the workpiece is copper or other non-magnetic data can be processed. Compared with the grinding machine, the processing efficiency is 10 times that of the grinding machine on the basis of achieving the same accuracy, and the working hours of cleaning the grinding paste are also saved.

Precision inspection of the main components of the double-end grinder: round runout inspection of the outer diameter of the front end of the spindle and end face runout inspection install the spindle and spindle bearing into the shaft sleeve, pre-tighten and rotate the spindle, and make a meter at the outer diameter of the front end of the spindle to detect the large difference of the dial runout. Check the coaxiality of the upper and lower spindles.

Fix the dial indicator to the lower spindle flare plate, hit the dial indicator on the positioning journal surface of the flange plate of the upper grinder spindle grinding wheel, the upper spindle does not move, and the lower spindle rotates for one week to obtain a large difference in dial runout. 1/2 of the difference is the measured coaxiality. Fix the dial indicator to the lower spindle flare plate, hit the dial indicator on the front end surface of the grinder, and the upper and the upper and the upper and lower spindle rotate at the same speed for one week, the large difference in dial beating is parallelism.
