The service life is very important for any product, so is the linear optical axis. The service life affects its performance and change in the process of work. So how do we measure the service life of the optical axis?

The characteristics of the straight optical axis have been very clear, but do you know about its classification? There are three main types of linear optical axis, namely, crankshaft, straight axis and flexible axis, in which the straight axis can be further subdivided, and mainly according to different purposes to be distinguished. Precision axis

Hollow axis is also a kind of linear optical axis, it is used in a variety of occasions, so the installation of the relevant natural to know. For example, what should we do to install the hollow shaft and the drive plate now? Optic axis

If you need to purchase both linear guides and sliders, you can choose the brand that has been approved, and then you need the specifications of linear guides to the manufacturer.

At present, there are many kinds of linear guideways on the market, and the types of them are also combined by different letters. Even so, the basic structure and parameters are basically the same. What are the main parameters of the linear guide? Optic axis

Although the quenched and tempered piston rod has good comprehensiveness and high wear resistance, it is a connecting part supporting the piston to do work, but the premise to obtain these advantages is good processing conditions.

First of all, we must understand the manufacturing process of quenched and tempered piston rod. It is formed by rolling. A cold hardening layer is formed on the surface of the rolling surface, which helps to reduce the elastic and plastic deformation of the contact surface of the grinding pair, improve the wear resistance of the surface of the cylinder rod, and avoid the burns caused by grinding.

In order to avoid the above phenomena, the piston rod must have sufficient strength and stiffness, and light weight. However,

The electroplating treatment of piston rod is not simple, but also requires a higher technical content, it is necessary to remind everyone about this.

Firstly, the small machining allowance is used to shorten the processing time and reduce the cost of parts manufacturing. Secondly, sufficient machining allowance should be ensured,

Auscultation method of long shaft pump deep well pump with the normal operation of the long shaft, accompanied by sound has always been a certain rhythm and rhythm.
