Stainless steel is a kind of steel that can resist weak corrosive media such as air, steam, and water, or has the ability to prevent rust. In our lives, we can see all kinds of stainless steel utensils everywhere. Stainless steel components have become an indispensable part of our lives, and the use of different equipment in the CNC turning services of stainless steel parts is also different. Precision CNC turning stainless steel parts has the characteristics of wear resistance, corrosion resistance and durability, and is an important choice for high-end equipment spare parts. In medical engineering technology, mechanical equipment, automobiles, industrial equipment, automation equipment, household appliances, toys and other industries that require durability, stability, and good finish, stainless steel turning parts are widely used.
The following knowledge points are listed below:
Basics about stainless steel turning parts
Evolution of stainless steel
Advantages of stainless steel turning parts
CNC turning is a cost-effective process for machining various profiles of precision parts, including planes, contours and radii. CNC precision turning relies on a rotary drive, which firmly fixes a cylindrical metal part in one position. The tool then moves on 2 axes to produce precise depth and diameter in the finished product. When the cylinder rotates, the material removed from the cylinder becomes metal chips (also called chips or bent chips).
Different types of turning operations include: tapered turning; spherical generation; difficult; flat grooving (similar to boring); end face (the tool rotates the material at a right angle); knurling (used to make grips); reaming (Small and precise holes); threads (screws); and polygonal turns (for non-circular turns).
In the CNC turning process, a metal rod is rotated while holding the tool against the inventory to remove material and create the final turning part. The lathe quickly machine your parts subtractive turning process with additional live molds. The outer diameter (OD) and inner diameter (ID) threads are also available.
The turned parts can be left as machining, with visible tool marks, or bead spray. When the run is complete, the parts are checked, boxed and shipped shortly after.
The material worked on turning processes could be copper/stainless steel/aluminum/zinc/magnesium, etc.
Stainless steel alloys are divided into two types: ferrite and martensite. Ferritic alloys contain 10-12% chromium and are not hardenable. Martensitic alloys have a higher chromium and carbon content than ferritic stainless steels, and the addition of manganese and silicon produces an alloy that can be hardened by heat treatment. Today, ferritic and martensitic stainless steels are generally not used in large quantities in industrial environments, but in household products such as kitchens or gardening tools.
With the development of stainless steel applications, alloys are often used in applications requiring mechanical strength and corrosion resistance. To increase the strength of the alloy, metallurgists added nickel to the alloy. The iron/chromium alloy becomes an iron/chromium/nickel alloy. These materials are called austenitic stainless steels, and they are common in today's industrial applications that require strength and corrosion and heat resistance. This alloy is usually used in petrochemical processing, food industry where hygiene standards require corrosion resistance, and general machinery used in harsh environments.
Inevitably, improving the performance of an alloy (such as stainless steel) will also increase the challenges of machining it. The corrosion resistance of ferritic and martensitic stainless steel alloys is basically chemical, so the processing difficulty of these alloys is not much greater than that of ordinary steel. However, the addition of nickel and other elements to austenitic stainless steel can increase the hardness, toughness, resistance to deformation and reduce the thermal properties of workability.
(1) Good corrosion resistance, longer durable than ordinary steel
(2) High strength, so thin plate will be widely used.
(3) High-temperature oxidation and high strength, it can resist fire
(4) Normal temperature processing, so easy plastic processing
(5) It is simple and easy to maintain because there is no need for surface treatment
(6) Cleaning, highly polishing surface
(7) Good welding performance
