Working principle of slow wire processing

 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?

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

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...

Application occasions of economical concentric tube micro-lubrication device

Concentric tube Tur oil-air lubrication system is suitable for machine tool electric spindles and various high-speed bearings, center frames, guide rails, lead screws and other oil and gas lubrication. It is also especially suitable for external cooling metal cutting processing, suitable for gear processing, milling, turning, and drilling. The equipment for cold processing outside machine tools such as machining centers and the transformation of old machine tools realize energy saving and environmental protection.

Combining the nozzles to achieve lubrication and cooling to prevent aggravation of wear; oil and gas are transported in a split way, and mixed at the lubrication point terminal to make the lubrication more reliable. The oil feed frequency of the pneumatic micropump is controlled by the autonomous controller, and the micropump can manually adjust the output flow of each stroke. The pressure switch can be selected according to the actual situation to detect the gas source pressure and oil and gas pressure and give an interlocking alarm signal when the pressure is lower than the set value. The fuel tank level switch monitors the fuel tank level and triggers an alarm when the fuel level is low. The modular design makes this system particularly adaptable and easy to increase and decrease the number of lubrication points. Using an external controller can further expand the adaptability of the device. The application of high technology enables the lubrication device to be independently controlled, easy to install, and easy to adjust.


The Sipu concentric tube device is an economical dual-channel oil and gas lubrication device developed according to the actual needs of customers. The SP concentric tube device mainly includes the following functions:

1. Adjustable oil supply volume: The adjustment of the oil volume per unit time of the SP concentric tube device adopts the adjustment mode of frequency + single oil supply volume, that is, after setting the oil supply frequency and the single oil supply volume. Get the oil output per unit time.

2. Quick response: The special structure of the SP concentric tube device (oil and gas are transported separately) avoids the shortcomings of long response time, and its application occasions have also been expanded;

3. Lubricant consumption is greatly reduced;

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect. 4. Improve work beat;

5. Better surface finish of the workpiece; 6. Flexible and light: The SPU concentric tube device is small in size and can be used in a small installation location.

7. Strong equipment stability: The device is powered by compressed air, with few moving parts, low maintenance, and strong stability.
