Fork parts, ear hole, inner corner clamp

It is difficult to machine the inner corner of the ear hole (chamfering) or remove the burr. To this end, we have designed and manufactured special fire tools to ensure quality. The taper shank 7 (see figure) is loaded into the vertical drill spindle hole, the lower ear hole of the workpiece is mounted on the positioning block 2, and the rear part of the workpiece abuts against the stop pin 6, and the vertical drill is started to make the taper shank 7 from the workpiece The upper ear hole passes through, and when the cutter head 3 contacts the ball portion of the positioning block 2, the compression spring 5 is compressed, and the two cutter heads automatically open to both sides.

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.
