CNC machining impeller technology and clamping plan

According to the material, structural characteristics and technical requirements of the impeller, the CNC machining plan is analyzed and studied, including the machining process, technical difficulties and technical measures taken. It is recommended to add required process fixture bosses at one end of the impeller, and design and develop a special fixture mold to meet the requirements of impeller processing.

Micro CNC machining parts technology

Super finishing of turning and milling micro parts

The micro CNC machining technology adopts a fully automatic method to super-finish the surface of metal parts. Through a kind of mechanochemical action, the material of 1-40μm on the surface of the metal parts is removed, and the surface quality of the processed surface reaches or is better than the N1 level of the ISO standard. Micro CNC machining technology is mainly used in the two fields of ultra-precision polishing and ultra-precision brightening.

NC milling of precision stainless steel parts

cnc milling of stainless steel parts

The characteristics of milling stainless steel are: stainless steel has strong adhesion and fusion, and the chips are easy to adhere to the teeth of the milling cutter, which makes the milling conditions worse;
When up-milling, the cutter teeth slide on the hardened surface first, which increases the tendency of work hardening; When milling, the impact and vibration are large, which makes the cutter teeth of the milling cutter easy to chip and wear.

Parameters of high-speed milling stainless steel parts

milling cutter milling stainless steel cutting amount table

Set the cutting amount of high-speed steel milling cutter for milling stainless steel and the choice of milling cutter
First of all, the coolant will cool the chips too quickly and merge into the blade, resulting in reduced tool life;
Too high a feed rate will cause material accumulation, while a too low feed rate will cause friction between the tool and the workpiece, and will also cause overheating.
In fact, in order to avoid the edge of the knife, CNC machining stainless steel cutting heat is necessary. For stainless steel milling cutters, the appropriate milling speed should be selected to make the chips have a light brown color.

How to machine stainless steel parts? CNC Machining Technology and Application of Stainless Steel Parts
Stainless steel is a versatile machining material that can be widely used where strength and resistance to heat and corrosion are essential. However, the same properties that make stainless steel alloys exceptional structural materials also complicate the processes used to machine them. A careful combination of cutting tool properties, geometries and the application of cutting parameters can significantly increase the productivity of stainless steel machining operations.

Turning Stainless Iron Parts

Turning Stainless Iron Parts on Automatic Lathe

Although roughing, semi-finishing and finishing of stainless-iron materials on general-purpose machine tools is not too difficult. However, how to solve the problems of high cutting force, high temperature, serious tool wear and low durability, poor surface quality and low productivity in stainless steel cutting on a high-productivity special automatic lathe. It is difficult to meet the requirements of the drawing in one turning operation. In the process of CNC machining martensitic stainless steel materials in our factory: from the selection of tool materials, the selection of tool geometry and structure; Selection of cutting amount; feed state of blank material; Repeated tests have been carried out on the selection of lubricants and coolants, and certain successful experiences have been obtained. Take 3Cr13 stainless iron as an example.
