ER20 Spring Collet

Product Introduction

Most of the machines are spliced by many parts. To fix those small parts, ER20 Spring Collet is required. This is a cylindrical fixture/fixture that is used on the milling machine and can play a drill or milling cutter. It is very suitable for processing small-diameter workpieces, and the time for clamping workpieces is very short, which can realize fast loading and unloading. At the same time, its replacement time is very short, which can realize the rapid replacement of different sizes of fixtures.

All ER20 Spring Collets conform to DIN 6499B standard. It is made of high-strength metal materials by quenching and has been treated at low temperatures, so its performance is very stable, wear-resistant, and durable. The model has a large clamping force and wide clamping range and belongs to a high-precision spring chuck. At the same time, its inner hole can reach the standard of Ra0.4 after multiple grinding. The hollow groove of the collet is ground, which is more suitable for high-speed machining.

Technical Parameters

● Installation method

1. Install the ER20 Spring Collet to the eccentric circle of the nut, and push it in the direction indicated by the arrow until a click occurs.

2. Then install it on the tool.

3. Tighten the nut.

● Disassembly Instructions

Unscrew the nut from the handle and pull out the tool. Push inward from the front of the spring collet and press it down to the bottom of the eccentric circle at the same time. Push the collet diagonally until the collet and nut separate.

● Eccentric circle

In order to facilitate the installation and disassembly of the collet, the nut is designed with an eccentric groove (the upper space is larger than the lower space). When using, you need to install and remove from a small position.

Advantage:

Cryogenic treatment:

1. Ultra long term low temperature treatment at - 185 ° C can transform austenite into martensite.

2. The precipitated nano carbide particles improve the hardness and toughness of the product.

3. Improve wear resistance.

Aging treatment:

The residual internal stress in the grinding process is removed by ultra-long thermal aging of more than 100 hours.
