Product Introduction

Milling machine collet, 65Mn material, high elasticity, high tensile strength, high fatigue strength, prolong the service life of the spring, improve the quality of the spring collet. High clamping force and wide clamping range. Accuracy is suitable for most processing needs, cost-effective.

The purpose of CNC milling machine ER collets is to transmit the maximum clamping force to the tool, so that the tool can achieve the smallest runout, which is beneficial to prolong the service life of the tool, make the accuracy meet the requirements, and make our products more refined.

Technical Parameters

Features：

This spring collet can realize high concentricity clamping of the tool, can obtain longer tool life and higher precision speed, and can improve the surface finish of the workpiece, and the precision adjustment is less than 5 microns, and the clamping diameter ranges from 1mm-36mm.

Due to its good concentricity and balance, the collet chuck can be used in machining with spindle speed up to 3000/min. Using this collet with good concentricity, the radial runout error is smaller, and all cutting edges of the tool can be Participate in cutting uniformly, which can improve the cutting performance and service life of the tool.

Below we explain the installation and use precautions of ER collet

1. Before use, clean the spindle, clamping nut and collet cone

2. Put the collet into the nut. When installing, the collet must be inclined at a certain angle and gently put into the groove of the clamping nut.

3. Put the straight shank tool into the spring collet and lock it with a wrench

Notice:

1.The length of the tool inserted into the collet should not be less than 2/3 of the clamping length. If the tool is incorrectly inserted, the collet will be permanently deformed, resulting in a large radial error.

2.When using the collet, pay attention to the clamping range of the collet. The clamping range of the common spring collet is between the inner diameter of the collet and the inner diameter of -1mm, and the clamping range of the waterproof collet is between the inner diameter of the collet and the inner diameter of -0.5mm. 

Corporate purposes:

1. Professionalism comes from details, and details come from focus

2. Create value for customers, create opportunities for employees, create benefits for shareholders, and create tomorrow for the society

3. The heart is proud of the world, and the truth is pursued
