How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Dimensional control skills for stainless steel parts processing


Modify tool offset value to ensure dimensional accuracy

 

According to stainless steel parts machining manufacturers, when the workpiece error exceeds the workpiece tolerance due to the first tool setting error or other reasons, and the processing requirements cannot be met, the workpiece can be modified to achieve the required size by modifying the tool compensation. The method to ensure the radial size is as follows:

 

Absolute coordinate input method

 

According to the principle of "large reduction, small increase", modify the tool compensation at 001004. If the workpiece size is larger by 0.1mm when cutting the groove with the No. 2 cutting tool, and the tool compensation display at 002 is X3.8, you can enter X3.7 to reduce the No. 2 tool compensation.

 

Relative coordinate method

 

As in the above example, input U-0.1 at 002 cutter compensation, and the same effect can also be obtained.

The same is true for the cnc operating of the axial size. For example, if you use the No. 1 external tool to machine a certain shaft segment, and the size is longer than 0.1mm, you can enter W0.1 at the 001 tool offset.

 

Semi-finish machining eliminates the influence of screw gap to ensure dimensional accuracy

 

According to the analysis of stainless steel parts processing manufacturers, for most CNC machining, after a long period of use, due to the influence of the screw gap, the size of the processed workpiece often appears unstable. At this time, we can perform a semi-finishing process after roughing to eliminate the influence of screw clearance. For example, after rough machining the outer circle with No. 1 tool G71, you can input U0.3 at 001 tool compensation and call G70 fine turning once. After stopping the measurement, input U-0.3 at 001 tool compensation and call G70 fine turning again. . After this semi-finished turning, the influence of the screw gap is eliminated, and the stability of the dimensional accuracy is ensured.
