One: The impact of burrs on the function of parts and the performance of the whole machine
1, the impact of parts wear, the greater the burr on the surface of the part to overcome the resistance of the greater the energy consumed. The presence of burr parts may produce matching deviations, and the more rough the matching parts are, the greater the pressure within the unit area, and the surface is more prone to wear.
2, the impact of corrosion resistance, parts after surface treatment of burr parts are easy to be touched off, will damage the surface of other accessories, while the burr surface will form a new surface without surface protection, under wet conditions, these surfaces are more prone to rust and mildew, thus affecting the corrosion resistance of the whole machine.

Two: The impact of burrs on subsequent processes and other processes
1, processing burrs on the base level is too large, finishing will lead to uneven processing allowance. Deburring machine
Due to excessive burrs, the cutting amount of the spindle will suddenly increase or decrease when cutting at the burr part, which will affect the smoothness of the cutting and produce knife lines or processing stability.
2, if there is a burr in the precision base surface, the base face is easy to coincide, resulting in inaccurate processing size. Deburring equipment
3, in the surface treatment process, such as the spraying process, the coated metal will first gather at the tip of the burr part (static electricity is easier to adsorb), resulting in the lack of plastic powder in other parts, resulting in unstable quality.
4, burrs in the heat treatment process is relatively easy to cause bonding, often destroy the interlayer insulation, resulting in a significant decline in alloy AC magnetism, so soft magnetic nickel alloy and other special materials must be removed before heat treatment.
Three: The importance of deburring
1. Reduce and avoid the presence of burrs affecting the positioning and tightening of mechanical parts, reducing the processing accuracy.
2. Reduce the scrap rate of the workpiece and reduce the risk of the operator.
3. Eliminate the wear and failure caused by the uncertainty of burrs in the use of mechanical parts.
4. The adhesion of burrless mechanical parts will increase when painting, making the coating texture uniform, uniform appearance, smooth and clean, and the coating firm and durable.
5. Mechanical parts with burrs are prone to cracks during heat treatment, reducing the fatigue strength of parts, and deburring of parts that bear load or operate at high speed cannot exist.
