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

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

What material is used for medical parts

According to the working characteristics of medical parts, it is required to be resistant to a certain temperature during disinfection (usually high-temperature steam disinfection), not to be rusty, high in strength, hardness (scalpel), and not easy to deform. Generally, stainless steel is selected, and stainless steel has The materials with the above characteristics are martensitic stainless steel, such as 3Cr13 and 4Cr13 martensitic stainless steel and 9Cr18 machining stainless steel spring , etc., and martensitic stainless steel is the cheapest stainless steel, which can meet the requirements of medical equipment.
The heat treatment process is basically quenching + low temperature tempering.

  • 3Cr13 steel quenching temperature 1000~1050°, oil quenching, tempering temperature 150~350°
  • 4Cr13 steel quenching temperature 1050~1100°, oil quenching, tempering temperature 150~350°

When tempering these two kinds of steel, try to choose a higher temperature, such as 300 °, for the need of high temperature disinfection (high temperature disinfection water vapor can reach 300 °)

The quenching temperature of 9Cr18 steel is 1000~1050, oil quenching, tempering temperature is 200~300. Of course, the above mentioned are all kinds of surgical medical machining equipment, injection puncture equipment, plastic surgery equipment, general examination equipment, family planning equipment, orthopedics (Orthopedics) ) Surgical instruments and other materials, such as scalpels (scalpel handles and blades, skin knives, wart peeling knives, lancets, spatulas, razors, dander scrapers, picking knives, front knives, pedicure knives , Manicure knife, scalpel), surgical scissors (ordinary surgical scissors, tissue scissors, comprehensive tissue scissors, suture removal scissors, plaster scissors, dissecting scissors, gauze bandage scissors, educational surgical scissors), various forceps (ordinary hemostatic forceps) , Small blood vessel hemostatic forceps, mosquito hemostatic forceps, tissue forceps, cemented carbide insert needle holders, ordinary needle holders, wound crimping forceps, skin pressure forceps, bullet forceps, gauze peeling forceps, sponge forceps, scarf forceps , Skin tube forceps, instrument forceps), forceps for basic surgery (small vessel forceps, non-invasive forceps, tissue forceps, plastic forceps, needle-holding forceps, health forceps (simple forceps), plucking forceps, tissue forceps, dressing forceps , Dissecting forceps, hemostatic clip), basic surgical needles, hooks (aneurysm needles, probes, hair pushing needles, hair transplanting needles, picking needles, straight-pointed needles for teaching, vein retractors, wound hooks, flat retractors, double-ended retractors , Skin retractors, anatomical hooks), stethoscopes, etc., do not include the machining materials of medical equipment, such as X-ray machines, B-ultrasound, CT, photographic equipment, laboratory equipment, etc. The materials of these overall equipment are based on the technical requirements of the parts of the equipment Different, you can choose from a wide range of varieties.
