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 better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Doppsyp concentric tube lubrication equipment

Doppelt is committed to leading the development of the lubrication industry in the direction of energy conservation and environmental protection. It 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 technology in the fields of metal cutting, high-speed bearings, and various common friction pairs. According to customer needs, Doppel continuously releases new products into the market. They are becoming good assistants for customers to reduce manufacturing costs, increase production efficiency, and green manufacturing.


The Sipu concentric tube device is an economical oil-air lubrication device developed by Doppy according to the actual needs of customers. Customers can choose corresponding components according to their needs. This model allows customers to have more autonomy in reducing the cost of the oil-air lubrication device, improving the use effect, and increasing the flexibility of operation. The SP concentric tube device mainly has the following functions:

1. Adjustable oil supply volume: The adjustment of the oil volume per unit time of the Sipu concentric tube device adopts the adjustment mode of frequency + single oil supply volume, that is, the unit time can be obtained after setting the oil supply frequency and the oil supply volume.的油量。 The oil output.

2. Quick response: The outstanding feature of the SP concentric tube micro-lubrication device is quick response. In practical applications, some occasions require quick response. The special design of the Sipu concentric tube device (oil and gas delivery separately) avoids the shortcomings of slow response speed and long waiting time, and its application occasions have also been expanded.

3. Flexible and light: The SP concentric tube device is small in size, and it is flexible and convenient to choose the installation position.

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


Today, when the demand for lubrication is getting higher and higher, lubrication equipment will continue to improve and innovate to meet the requirements of new forms. Improving the practicability and efficiency of lubrication equipment is the direction of Doppy’s efforts. Doppy will also help more customers to make more efforts in cost reduction and green manufacturing.
