stainless steel cnc machined parts Technical requirements:
1. Tolerance requirements
(1) The unmarked shape tolerance shall meet the requirements of GB1184-80.
(2) No note length size allowable deviation ±0.5mm.
(3) The casting tolerance zone is symmetrical to the basic size configuration of the blank castings.

2, cutting workpiece requirements
(1) The parts shall be inspected and accepted according to the working procedure, and can be transferred to the next working procedure only after the inspection of the previous working procedure is qualified.
(2) The parts after processing are not allowed to have burrs.
(3) The finished parts shall not be placed directly on the ground, and necessary support and protection measures shall be taken. The finished surface is not allowed to have rust and decay and affect the performance, life or appearance of the bump, scratch and other defects.
(4) The surface of finishing rolling shall not have peeling phenomenon after rolling.
(5) There should be no oxide skin on the surface of the parts after heat treatment in the final process. After finishing the mating surface, tooth surface should not be annealed
(6) The surface of processed thread is not allowed to have defects such as black skin, bump, random buckle and burr.

stainless steel cnc machined parts have the following characteristics

1 serious work hardening: in stainless steel, with austenite and austenite + iron parent stainless steel work hardening phenomenon is the most prominent. Because of the large plasticity of stainless steel, plastic deformation character distortion, strengthening coefficient is very large; Under the action of cutting stress, part of austenite changes into martensite. In addition, compound impurities are easy to decompose and distribute under the action of cutting heat, so that the hardening layer is produced during cutting.

2, cutting force: stainless steel in the cutting process of plastic deformation, especially austenitic stainless steel (the elongation of more than 1.5 times of 45 steel), the cutting force increase. At the same time, the work hardening of stainless steel is serious, high thermal strength, further increase the cutting resistance, cut the crimp break is also more difficult

3. High cutting temperature: when cutting plastic deformation and friction between the tool are very large, the cutting heat, a large number of cutting heat are concentrated in the cutting zone and cutting contact interface, heat dissipation conditions are poor, under the same conditions than 45 steel high cutting temperature 200 "C.

4, cutting is not easy to break, easy to bond: stainless steel plasticity, toughness are very big, at high temperature, high pressure, stainless steel and other metal affinity is strong, easy to produce adhesion phenomenon, and the formation of chipping tumor, not only aggravate tool wear, but also tear phenomenon and the processed surface deterioration. This characteristic is more obvious for martensitic stainless steel with lower carbon content

5 tool easy wear: cutting stainless steel in the process of affinity, so that the cutting between the bond, diffusion, so that the tool to produce adhesive wear, diffusion wear, resulting in the tool front surface of the crescent, cutting edge will form a tiny spalling and notch; In addition to the carbide in stainless steel (such as TiC) particle hardness is very high, cutting direct contact with the tool, friction, abrasion tool, and work hardening phenomenon, will aggravate the tool wear.
