How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

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

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

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.
