Factors Affecting Cutting Surface Roughness in Precision Mechanical Parts Processing

1. The influence of cutting force and friction force. When precision parts are processed and cut, the arc of the cutting edge of the special tool and the extrusion and friction against the side of the product workpiece will cause plastic deformation of the metal material, which will cause the current residual area to distort or aggravate the concave groove, and increase the roughness of the surface At this time, the cutting chips become crushed particles, and the processed surface often shows the impression of particle collapse, leaving many dents, making the surface rough.

 

2. The effect of work hardening. When the cutting tool cuts plastic at a certain speed, some small particles on the cutting will adhere to the top of the front edge, forming a high-toughness accumulation edge, which can replace the front edge and cutting edge laser cutting.

When the sliding friction between the cutting edge and the accumulation edge exceeds the spray welding strength between the accumulation edge and the front edge, or when it is damaged or vibrated, the accumulation edge will burst, and the newly created -up edge will be in the Then slowly transform into . The generation, growth and fall of build-up edges can seriously affect the surface roughness of the part.

 

3. The impact of scales and thorns. During the cutting process, due to the friction and spray welding on the cutting surface during machining of precision parts, cutting chips will regularly stay on the surface of the rake tool, thereby squeezing the newly processed surface. In obvious cases, the surface will tear. Phosphorous spines are produced on the surface, making the surface rough and uneven.

Due to the influence of the above physical factors on the surface roughness, in order to better reduce the surface roughness, in addition to reducing the plastic deformation caused by the cutting force, prevent the accumulation of tumors and desquamation during the processing of precision parts.
The main process method is: choose the cutting speed that is not easy to cause accumulation edges and thorns, improve the cutting performance of the material, and choose the cutting fluid appropriately.

Q: Do you have stock in stock?
A: This product is a customized product, the pattern and price are only for the buyer's reference.

 

Q: Order process
A: We can quote according to the drawings or samples of the products to be produced by the buyer, and provide specifications, materials, production requirements, etc. The specific unit price will be quoted according to the size, quantity, material and thickness, process complexity, production requirements, etc.

 

Q: Delivery time
A: Different materials and styles have different production processes and different time. Please consult customer service for details.

 

Q: About transportation
A: Because the customized products have different specifications, varieties, materials, etc., the freight cannot be accurately calculated, so the quotation does not include the freight. If you need a quote including shipping, please contact us. Thanks!
