The burr on the mechanical parts is just like the thread ends on the new clothes we bought. It is superfluous and affects the beauty and quality. Today, Yize mould will share with you our specification for burr improvement of precision machinery equipment parts.
Some of the burr on mechanical parts is caused by plastic deformation during cutting; some are caused by the flash of casting and die forging, and some are the scraps of welding extrusion. With the improvement of industrialization and automation, especially in the field of aviation, aerospace, instruments and meters, the harm of burr is particularly obvious, which gradually attracts people's attention, and begins to study the generation mechanism and removal method of burr. According to years of experience, precision machinery parts processing manufacturer Yize summarizes several specification for burr improvement of precision machinery equipment parts.
1. The way to push burr is wrong. Solution: the oilstone must be clean, flat and often cleaned; the tail of the part should contact the stone first, push it back and forth smoothly, and then push the molding position into the oilstone to push the burr (pay attention to the whole process, the force should be uniform and stable, the force should be small when contacting the stone, and it should be increased slowly)
2. The burr is skewed when pushing the burr. Solution: sheet parts should be attached with balance block pushing burr, and the right angle of balance block must be within 0.002; the balance block should contact the oilstone first, then slide the part slowly; the force should be stable and even, and can not be pushed vigorously.
3. The blade is easy to scratch parts. Solution: do not use blade to deburring. Use 1200 × fiber oilstone, copper sheet or copper brush instead. The force should be stable and even, and can't be scraped vigorously.yizali2iL
4.Small zero deburring is easy to lack corner. Solution: select the "L" shaped fixture, the right angle of the fixture is within 0.002; the two surfaces of the parts should be close to the two surfaces of the fixture, and the parts should not be loosened by hand; the fixture should contact the oilstone first, and then slide the parts slowly to contact the oilstone; keep the contact surface of the parts and the fixture tightly and push it gently on the oilstone. If the burr can not be removed, the burr should be removed by adding appropriate strength.
Attention: the burr should be flat, stable and even when pushing the burr. Use a magnifying glass to confirm whether there is any missing angle in the appearance, and use the projector to confirm the places that can not be seen clearly.
The above is our specification for burr improvement of precision machinery equipment parts. Although burr is only a small thing, it can directly affect the quality of products. Based on the manufacturing spirit of mold parts, even the precision parts, as long as there is a little defect or missing angle, all efforts will be in vain. Our. Production process in strict accordance with the production process steps to complete the workpiece. "No acceptance, no manufacturing, no outflow" defective products.
