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

KOVAR parts seal preparation and physical properties

Kovar® is a vacuum-melted iron-nickel-cobalt low-expansion alloy. The chemical composition content is controlled in a very narrow range to ensure accurate and balanced thermal expansion performance. At the same time, strict quality control during the manufacturing process of KOVAR machining parts also ensures balance Its physical and mechanical properties are more suitable for deep drawing, stamping and various cutting processes. Material use Kovar® is used for vacuum sealing of hard glass and ceramics, and is widely used in electron tubes, microwave tubes, transistors and diodes. On integrated circuits, it is used for flat integrated circuits and dual in-line packages. Seal preparation All parts made by Kovar® should be degassed and annealed in a wet hydrogen atmosphere. Hydrogen is injected into water at room temperature and gets wet through blisters. Care must be taken to prevent surface carbonization. The heat treatment furnace must have a cooling chamber that provides the same a

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

The difference between CNC machining, CNC machining and traditional machining

 Numerical control machining is the same as CNC machining. The production process is derived from the conventional machining technology of daily life. It is an organic combination of conventional machining technology, computer numerical control technology, computer-aided design and auxiliary information technology. Due to the continuous innovation and development of electric tools, more and more parts need to be precisely processed in modern manufacturing, and the requirements for machining accuracy and surface complexity of the workpiece are also increasing. Therefore, CNC machining has received widespread attention, but in terms of saving resources and costs, CNC machining is still more expensive than traditional machining time. The following is our specific situation to introduce the difference between CNC machining and traditional machining technology.



1. Machining technology

In the ordinary CNC machining process, whether it is positioning datum, clamping method, tool, cutting method analysis, etc., it can be simplified through a process, but the data and machining production process are more complicated, and we need to carry out these influencing factors. Fully considered, and even for the same machining task, the CNC machining process can have multiple design solutions, and multiple machining parts and machining tools can be used as the main line of development for construction process arrangements. The process has more diversified characteristics , This is the difference between CNC machining process and traditional machining process.

2. Power tools and fixtures

In the CNC machining process, not only the coordinate direction of the fixture and the machine tool must be determined, but also the size relationship between the part and the machine tool coordinate system must be coordinated. In addition, the two steps of positioning and clamping need to be effectively controlled during the clamping process. Under the traditional machining technology, due to the limited machining capacity of the machine tool itself, it is necessary to perform multiple clamping during the machining. As well as the need to use special fixtures, the design and manufacturing costs of fixtures have risen, which invisibly increases production costs. The positioning of the CNC machining process can be used to debug the instrument. In most cases, no special fixture design is required, so its cost is relatively low.

3. Tool

In the production process of CNC machining, the selection of tools needs to be analyzed and determined according to the machining technology and machining methods. Especially in CNC machining, the use of information for high-speed cutting can not only help improve the efficiency of machining enterprises, but also the quality of processed products can be socially guaranteed, effectively reducing the probability of cutting deformation and shortening the machining cycle, so the demand for cutting tools Further increase.
