Inner end chamfering tooling of piston pin hole

Almost all pistons are designed to chamfer the inner end of the pin hole. In the manufacturing process, it is often used to directly cast chamfer or chamfer with a machine tool. The S1100 piston produced by our factory has the inner end chamfer of the pin hole shown in Figure 1. This chamfer is not easy to cast and is difficult to machine by general machining. The reason is that the chamfered surface is large, and the inner pin hole of the finished product is chamfered 3

Pipette

A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
