K12 Self-Centering 4 Jaw Steel CNC Lathe Chuck Factory

 1. Description
 

The full name of the four-jaw self-centering chuck is a manual four-jaw self-centering chuck for machine tools. It consists of a disc body, four small helical teeth and a pair of jaws. Four small helical teeth are engaged with the coil wire, the back of the coil wire is a flat thread structure, and the claws are equally installed on the flat thread. When the small helical tooth is pulled with a wrench, the coil turns, and the flat thread on its back causes the jaws to approach or retreat to the center at the same time. Since the pitches of the flat rectangular threads on the coiled wire are equal, the moving distances of the four claws are equal, which has the function of automatic centering.

The four-jaw self-centering chuck has two types of jaws: integral jaws and separate jaws. The overall claw is a claw in which the base claw and the top claw are integrated, and a pair of overall claw is divided into four positive claws and four reverse claws. A pair of separation claws has only four claws, and each claw consists of a base claw and a top claw. In addition, soft jaws can also be provided according to user requirements, and high centering accuracy can be obtained after random configuration (grinding) to meet the clamping requirements.

Function: Synchronous movement of four claws is suitable for clamping square and square parts, as well as shaft and disc parts.

Applicable machine tools and accessories: ordinary lathes, economical CNC lathes, grinding machines, milling machines, drilling machines and machine tool accessories - indexing head turntables, etc.
