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 production process of KOVAR parts processing has a great relationship with the process, including the process environment elements and the optimization configuration elements of the process route. The process route process needs to be formulated by an experienced person. The following is a brief explanation of the process process.

The formulation of the process route process: First, the geometric structure of the parts, the core parts of the accuracy index, the accuracy requirements, material characteristics, heat treatment requirements and performance requirements, etc. should be carefully analyzed, and then the blanks of the parts should be reasonably selected, the cnc machining china equipment should be used reasonably, and reasonable measures should be taken. Many process links such as stress process measures are reasonably configured. In the production organization process, the process is strictly implemented. During the process, strict inspection is performed. For general precision parts, the process route is: rough machining-aging-semi-finishing -Finishing can be done. Facing the processing of precision mechanical parts, such a processing route is obviously not enough. The processing route must be lengthened, and aging treatment must be properly interspersed, and super-finishing procedures are configured to ensure the processing requirements.

The usual process flow is: primary roughing-primary thermal aging-secondary roughing-secondary thermal aging (or vibration aging)-semi-finishing-vibration aging is enough-finishing-natural aging (or low temperature stability treatment)-precision Processing. Among them, the heat treatment requirements of precision parts should be arranged according to the different requirements of the overall hardness, partial hardness, and surface hardness of the parts. The stable processing of the precision mechanical parts processing accuracy is also very critical and complex, simple one or two. This method has been unable to meet the requirements, and usually adopts a variety of methods according to needs, such as stress annealing, low temperature stabilization, vibration aging, natural aging, and even cold treatment to achieve the accuracy and stability requirements of precision parts.

In order to ensure the machining accuracy, roughing and finishing are best performed separately. Because of the large amount of cutting during rough metal machining, the workpiece is subjected to large cutting force, clamping force, heat generation, and the machined surface has a significant work hardening phenomenon, there is a large internal stress inside the workpiece, if rough or rough machining Continuously, the precision of the parts after finishing will be quickly lost due to the redistribution of stress. For some parts that require high machining accuracy. After rough machining and before finishing, low temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.
