Reaming problems arising from the causes and measures to solve them
In the process of reaming, many problems such as out-of-tolerance hole diameter and high surface roughness of the inner hole often occur. Cause of the problem The aperture increases, the error is large The design value of the outer diameter of the reamer is too large or there are burrs on the edge of the reamer; the cutting speed is too high; the feed rate is improper or the machining allowance is too large; the main deflection angle of the reamer is too large; the reamer is bent; Cutting edge; the reamer edge swing is out of tolerance during sharpening;

Use of machining centers
1. The object to be processed is selected Before determining the object to be purchased, the object to be machined should be clearly defined. Generally speaking, parts with the following characteristics are suitable for machining on a machining center. Workpieces with cumbersome positioning For example, multi-hole machining with a certain hole spacing accuracy requirement is easy to implement by using the machine tool with high positioning accuracy. Repetitive workpieces Suitable for machining small batches of single pieces. Small batch means in 1-100 pieces, the number of each batch is small, but also need to repeat production. Also, parts that are
