How to process the thin-walled workpieces in CNC Turning?

Thin-walled workpieces are special workpieces, and the process of turning is different from the general workpiece turning. When turning thin-walled workpieces, due to the poor rigidity of thin-walled workpieces, some problems may occur during the turning process. Below we will introduce the turning process of thin-walled workpieces. Let everyone turn thin-walled workpieces. Be able to understand s...

How to choose the proper material for medical puncture needle?

Before the design of medical puncture needles, we first need to have a certain understanding of the positioning of the quality of materials. So what are the noteworthy parameter standards we need to have for puncture needle materials? Straightness of the puncture needle structure: the straight line is an important reason why the work twitching is smooth after the outer needle body and the i...

Why do designers of surgical instruments prefer medical 304 stainless steel?

In the field of surgical instrument design, for the choice of materials, why do designers choose 304 stainless steel? In terms of stainless steel, we basically choose 304 grades for a small range of knowledge analysis of 304 series materials. 304 refers to SUS304 stainless steel. In fact, SUS is a Japanese material standard, and ASTM304 is a stainless steel produced in the United States. (0Cr18Ni9...

The three most commonly used Steel materials in mechanical design-SUS304, C45 and Q235

The origin of the name of these materials,304 is just a code for stainless steel, and has no special meaning，304 generally represents ASTM standard production, and SUS 304 represents Japanese standard production; the reason why C45 steel is called 45 is because its carbon content is 0.45%, so it is named 45 steel; The "Q" in Q235 represents the yield strength of the material. The following 235 mea...

Welding process problems and solutions in sheet metal processing

1. Welding of thick and thin plates When welding steel workpieces with molten metal gas shielding (GMAW) and flux cored gas shielded welding (FCAW), if the plate thickness of the workpiece exceeds the larger welding current that can be achieved by the welding machine, what will happen? The solution is to preheat the metal before welding. Use propane, standard gas or acetylene torch to p...

The difference between coarse and fine threads in machining.

1. Coarse threads do not need to be marked with pitch, such as M8, M12-6H, M16-7h, etc., mainly used for connecting threads. Compared with fine threads, due to the large pitch, the angle of thread rise is also large, and the self-locking property is poor. Spring washers are used together: the pitch is large, the thread profile is also deep, and the strength of the bod...

The process of welding repair for CNC machining stainless steel parts

Welding and repairing of mechanical parts is more troublesome than welding of steel structural parts, because welding and repairing parts must not only ensure the strength and rigidity requirements, but also ensure the overall size, shape and position accuracy and repairability requirements after repair. Welding and repairing of large and complex parts must be based on the wear and damage of the p...

How to avoid deforming in CNC Machining on Aluminum parts？

1.For parts with large machining allowance, in order to avoid heat concentration during processing, symmetrical processing should be adopted during processing. If a 90mm thick sheet needs to be processed to 60mm, if one side is milled immediately, the other side will be milled immediately, and the flatness will be 5mm once processed to the final size. The final size can ensure that the flatness re...

What's the difference of Laser cutting and Wire cutting?

Laser cutting refers to the use of high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporation forms a hole, and transfers through the movement of the material, the hole continuously forms a very narrow width (such as about 0.1mm) Sewing to complete the cutting of the material. Wire cutting refers to a proce...
