Custom CNC Machined Precision Transmission Housing

This custom aluminum transmission housing features multiple stepped diameters, internal bores, and machined grooves for precision mechanical assemblies.

The real challenge with parts like this is keeping the internal bore and outer diameters aligned, especially when the part needs to be turned around for machining on the opposite side.

Even when each diameter is within tolerance, small alignment errors between machining setups can cause problems during assembly.

For this type of part, we pay particular attention to the machining sequence, workholding, and the relationship between critical diameters. Where possible, we machine related features in the same setup to reduce alignment errors.

At Hofengfab, we manufacture custom CNC turned and milled components based on customer drawings, focusing on practical machining solutions and reliable assembly fit.
