One: The impact of deburring on the function of parts and the performance of the whole machine
1. The effect on the wear of parts, the greater the deburring on the surface of the part, the greater the energy consumed to overcome the resistance. The presence of deburring parts may cause a fit error. The rougher the fit, the greater the pressure per unit area, and the easier the surface is to wear.
2. Influence of anti-corrosion performance. After the surface treatment of the parts, the deburring part is easy to fall off due to waves and scratches, which will damage the surface of other parts. At the same time, a new unprotected surface will be formed on the deburring surface. Under wet conditions, These surfaces are more prone to rust and dew, which will affect the corrosion resistance of the whole machine.
Two: The impact of deburring on subsequent processes and other processes
1. If the deburring is too large at one time on the Yanzhun surface, the machining allowance will be uneven during finishing machining.
Uneven margin due to excessive deburring. When cutting the deburring part, the spindle cutting amount will actually increase or decrease, which will affect the smoothness of cutting, resulting in tool marks or processing stability.
2. If there is deburring on the precise datum plane, the datum faces are easy to overlap, resulting in inaccurate processing dimensions.
3. In the surface treatment process, such as the plastic spraying process, the coating gold will first gather in the deburring part (the circuit is easier to absorb), resulting in the lack of plastic powder in other parts, resulting in unstable quality.
4 deburring is easy to induce superbonding during heat treatment, which often destroys interlayer insulation, resulting in a decrease in the AC magnetic properties of the alloy. Therefore, deburring must be removed before heat treatment for some special materials such as soft magnetic nickel alloys.
Three: The importance of deburring
1 Low barriers and avoid affecting the positioning and clipping of mechanical parts due to the existence of deburring, reducing processing requirements.
2. Reduce the scrap rate of workpieces and reduce the risk of operators.
3. Eliminate the wear and failure of mechanical parts caused by the uncertainty of deburring during use.
4. The adhesion of the machine parts without deburring will be enhanced when the paint is painted, so that the coating has a uniform texture, a consistent appearance, smooth and tidy, and the coating is solid and durable.
5. Mechanical parts with deburring are prone to cracks during heat treatment, which reduces the fatigue strength of the parts, and deburring cannot exist for parts under load or parts operating at high speed.
