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

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

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

Four advantages of laser pipe cutting machine

The utility model has the advantages of tube blank cutting, tube wall cutting, tube wall cutting and other tube cutting shapes. Commonly used are mechanical cutting, punching and advanced laser cutting. For small batches, mechanical cutting methods are mainly used, such as turning, milling, circular saw cutting, and grinding wheel cutting. The main problem is low production efficiency and large environmental pollution. As an advanced processing tool, laser cutting machine is gradually entering the pipe cutting market.

The tube laser cutting machine is mainly used for cutting various hollow tubes of non-metal solid materials, such as plastic tubes, PVC tubes, PVB tubes and other industrial and civil materials. This kind of pipe is generally used for home decoration, industry and water conservancy construction.

Four advantages of laser cutting pipe processing

Laser cutting technology is a technology with high production efficiency and high productivity. The laser pipe cutting machine has four advantages.

1. High cutting accuracy, high dimensional accuracy, smooth cutting, no burrs, and low material loss;

2. The heat-affected zone of laser cutting is very small, and there is almost no thermal deformation and oxidation. It can produce high-quality and more consistent parts, which is especially beneficial for subsequent automatic welding;

3. High cutting efficiency, mass production can be realized. All operations of laser cutting can be unified into the same unit as a continuous operation process, which greatly shortens the logistics time. The standard pipe length is 6 meters, and the traditional processing method requires very heavy clamping. Laser processing can easily complete the clamping and positioning of several meters of pipe, making batch processing possible.

4. cnc turning china machine is controlled by a digital system, which is also one of the advantages of the laser cutting machine for cutting pipes. First, it guarantees accuracy and flexibility. Laser tube cutting technology can process any programmed shape, and can cut in any direction. The shape of the template can be changed quickly without the help of any tools. Modify the design plan without affecting the entire production process; the greater advantage is that the end user can control the production of short or medium versions without making a large number of templates, which can respond to customer needs faster and achieve personalization custom made.

It can be seen that laser cutting pipes can replace mechanical drilling, milling, sawing, punching or cleaning burrs and other processing procedures that require different equipment and hard tools to realize the cutting, chamfering, beveling, or hole cutting of complex pipe structures. Processing of possible size and shape features such as notches. With the rapid growth of China's stainless steel pipe production and consumption, laser pipe cutting equipment is rapidly popularized in China, and the demand for cnc milling china talents and laser pipe cutting technology is also growing rapidly.
