How to choose ER collet spring chuck with good quality?

November 20, 2020

Consumers in the purchase of Er spring collet, first, should look at the stability of the collet. Only make the ER spring collet and machine equipment know well, the machine and equipment will be able to travel slowly, in addition, to maintain a relatively low concentricity. It should be the accuracy of the ER chuck. In fact, the accuracy is very easy to measure. According to the standard of collet, the size of Er spring collet is different due to different machines and different positions.

It is very good to select the specifications of the collet, so that the machine can not be damaged when it is used. Therefore, before running the machine, the staff should first check whether the chuck and the machine have a good understanding, so as to prevent some problems. Sell low precision spring chuck, recognize Zhenhua CNC machinery, professional quality, quality assurance.

The basic structure of Er spring chuck has not changed very little. What is the reason?
1. The chuck can guide and clamp the workpiece accurately, which can resist the torque and endure the cutting force from the other direction.
2. The chuck has the function of reducing driving force (pulling force) and transforming driving force as clamping force of workpiece (or cutter).
3. The use of chuck has the low repetition precision under the premise of never reducing the machining accuracy and making the workpiece never damaged.
4. Have the ability to practice in a wide range of spindle speed and only large clamping force loss.
5. It has the function of quickly clamping the workpiece (or cutter).
6. The moment of inertia of highway workpiece is the largest.
