Effectively Reduce The Deformation Of Crankshaft Machining
May 04, 2018

Crankshaft roughing will be widely used CNC lathes, CNC milling machines, CNC lathes and other advanced equipment for CNC spindle, connecting rod journals for CNC turning, internal milling, car - broaching processing, in order to effectively reduce the crankshaft machining deformation. Crankshaft finishing will be extensively used CNC-controlled crankshaft grinding machine to finish grinding its journal. This type of grinding machine will be equipped with the functions of grinding wheel automatic balancing device, center frame automatic tracking device, automatic measurement, automatic compensation device, automatic grinding wheel dressing, constant line speed, etc. to ensure stable grinding quality. The dependence of high-precision equipment on the status quo of imports is not expected to change in the short term.

(1) During the crankshaft repair process, the crankshaft should be carefully inspected for defects such as cracks, bends, and twists, as well as the wear of the main bearing bushing and the connecting rod bearing, to ensure that the main journal and the main bearing, the connecting rod journal and the connecting rod bearing The gap between the fit is within the allowable range.

(2) Crankshaft cracks occur at the transition radius between the crank arm and the journal, and at the oil hole in the journal.

(3) The balance of flywheel operation should be ensured when repairing the crankshaft.

(4) After a major accident such as burning tiles or ramming cylinders occurs in the internal combustion engine, the crankshaft must be completely overhauled.
