Lo Pole Machine Cylinders Rehabilitation Methods
1. wear increases the diameter of the barrel, if there is a certain amount of nitriding layer, directly within the cylinder bores, diameter of grinding to a new dimension, and then prepared according to the diameter of the new screw.
2. barrel inner diameter after machining trimming back casting alloys, thickness between 1~2mm and precision machined to size.
3. General cylinder wears out quickly, this section can be (take 5~7D long) boring dressing, coupled with a nitriding steel bushing diameter reference holes in the screw diameter, stay in the normal clearance, processing and preparation.
