Working principle of slow wire processing

by
 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...

What are the rules for metal stamping die scrap tube?

by
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...

Introduction of KOVAR parts

by
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...

Advantages of dual-channel micro-lubrication equipment

cncmachining January 13, 2022

Doppelt is committed to the development of the lubrication industry in the direction of energy conservation and environmental protection, and is committed to the research and application of micro-lubrication in the field of mechanical processing and continuously launches new products in combination with practical applications. We have accumulated rich experience in the application of micro-lubrication in metal cutting, high-speed bearings, various common friction lubrication and other fields. New products are emerging in endlessly, and they are becoming a weapon for customers to reduce manufacturing costs, increase production efficiency, and green manufacturing.

…
The metal cutting dual-channel micro-lubrication device is a new economical oil-air lubrication device developed by Doppel according to the actual needs of customers. Customers can choose the corresponding parts according to the actual use. This model allows customers to have more autonomy in reducing the cost of oil and gas lubrication equipment, improving the use effect, and improving flexibility. The dual-channel micro-lubrication device mainly includes the following functions:

1. Adjustable oil supply: the dual-channel micro-lubrication device uses the frequency + single oil supply adjustment mode to adjust the oil supply. Set the oil supply frequency and the single oil supply to get the oil output per unit time. quantity.

2. Fast response: The outstanding feature of the dual-channel micro-lubrication device is fast response.In the practical application of oil-air lubrication, most lubrication occasions require quick response.The special design structure of the dual-channel micro-lubrication device (separate delivery of oil and gas) avoids the shortcomings of too long response time, and its application scenarios have also been expanded.

3. Flexible and lightweight: the dual-channel micro-lubrication device is small in size and can be used in small spaces.

4. Strong equipment stability: Compressed air is the power of the device, with few moving parts, low maintenance, and strong stability.

…
With the increasing demand for lubrication, lubrication equipment also needs continuous improvement and innovation. It is Doppy’s direction to improve the practicability of lubrication equipment and reduce costs and increase efficiency. Doppy will also help more customers to make more efforts in cost reduction and green manufacturing.
