Our large small arms are boring and milling in each pin hole
The big arms we make have to bore the big arm. Why do we have to boring every pin hole?
Excavator big forearm after the assembly, to wear the pin hole boring processing, to ensure that the arm every pin shaft parallel to each other, ensure that wearing a transverse and vertical axis pin pin hole, to ensure that in the center of the pin hole is apart from the precision;
After boring machine processed the forearm, can ensure the forearm in pin hole location accuracy, parallelism, a transverse vertical, to ensure that the big lower quality, improve the use of forearm guard life!
