How to process the cylinder piston more efficiently?

There are two ways to improve the machining efficiency of oil cylinder piston, the design and manufacture of mandrel fixture and the traditional machining method.

1, the traditional processing method, the blank material is selected, and the length is about 30mm, including clamping length (about 20mm), cutting length (5mm) and finishing allowance (3mm). Complete drilling, boring, threading, inner groove, outer circle, outer groove, chamfering and cutting in turn under the same clamping.

2. Design and manufacture method of mandrel fixture. Select a blank, first process the inner hole, inner groove and internal thread, then take out the workpiece and take it to another machine tool equipped with a mandrel, and position and process the rest of the piston, such as the outer circle, outer groove and chamfer, according to the matching of the inner and outer circle and the inner and outer thread.
