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

Precautions for machining aluminum parts on CNC lathes

​CNC lathe parts are processed with a variety of raw materials. Among them, aluminum parts are one of the more processed parts. When using CNC machine tools to process aluminum machining parts, you want to make the processing models and specifications more stable. Such areas must It is necessary to pay attention to the refrigeration problems of raw materials and the deformation of aluminum die castings after refrigeration. Such things are generally inevitable. At this time, it is necessary to pay attention to the application of diesel engine refrigerant as much as possible. Consider the deformation of raw materials.

Processing technology

Unscientific processing technology can easily lead to deviations in the model specifications of aluminum die castings. To ensure the basic processing technology (such as cutting CNC machine tool processing "first rough and then fine, face first and then hole, first many and then spicy small surface" or welding fixture application "reduce the frequency of clamping and use as much as possible to form fixtures" It is necessary to avoid the machining deviation caused by iron pins on aluminum parts as much as possible.

Basic parameters

Cutting rates, cutting speeds, cutting factors, and tool compensation are all cutting factors that impair the efficiency of processing, so special attention should be paid. Tool selection

When machining aluminum parts, use special-purpose tools as much as possible. Such tools are generally more purposeful. For example, turning tools special for aluminum milling generally have larger rake angles and helix angles, sharper cutting edges, which are more conducive to the processing of aluminum parts (such as anti-chip buildup), and the processed performance indicators will be stronger.

Stress field level

The aluminum material is too soft, so try to pay extra attention to the clamping range. In addition, during processing, the aluminum parts are roughed intact and left for a period of time before the next production process is carried out to remove the stress field.

In addition, it is necessary to pay attention to the milling surface and the demand of cutting fluid during the processing of aluminum parts. There are many factors that impair the efficiency of aluminum processing, so it should be handled flexibly during processing, and the actual problems should be analyzed in depth. Stable machine tools, effective processing techniques and tools, and the technical strength of their operators are all factors that impair product quality.

Tool selection

When machining aluminum parts, try to use special tools, which are generally more targeted. For example, lathes for aluminum milling generally have larger rake angles and helix angles, and the laser cutting edges are sharper, which is more conducive to the processing of aluminum parts (such as anti-chip buildup), and the processing performance will be stronger.

In addition, special attention should be paid to the difficulty of milling and the amount of cutting fluid required in the processing of aluminum parts. There are many factors that damage the credibility of aluminum processing, so it should be handled flexibly during processing, and specific difficulties should be analyzed in detail. Stable machine tools, reasonable processing technology and cutting tools, and the technical level of operators are all factors that harm product quality.

Processing technology

Unreasonable processing technology can easily cause errors in specifications and models of cast iron parts. In ensuring the basic processing technology (such as cutting CNC machine tools

Most of the basic processing technology key links such as "coarse first and then fine, surface first, hole first, many spicy noodles first" or "reduce the number of clamping times, try to use the composition of the tooling and fixture" in the use of fixture tools) Reduce machining errors caused by iron pins on aluminum parts.
There are many reasons for the deformation of aluminum parts, which are often related to raw machining materials, parts appearance, and production and processing specifications. There are several important aspects: deformation caused by blank welding stress, deformation caused by cutting force and cutting heat, and deformation caused by clamping force.
