1. Before welding burnish
Grinding range: 15-50mm on both sides of all welds.
Operation method: When grinding the long weld, the Angle grinder or straight handle grinder installed with stainless steel bowl brush is used to grind along the direction of the weld. For the welding seam that needs laser tracking and automatic welding, it can only be polished by straight handle grinding machine; In the relative welding accessories, larger workpiece surface welding accessories use thousands of blades on the welding surface for grinding or in the welding molding before the product needs to deburr processing products for grinding and polishing processing.
Technical requirements: polish metallic luster, ensure that there is no oxide film in the welding area, polish lines are parallel and uniform with the weld direction, and polish depth is not more than 0.2mm.
2. Polish the residual height of the weld
Range of grinding: 25-50mm on both sides of the weld.
Operation method: The Angle mill should be parallel to the polished surface when working, so that the residual height of the weld is removed; When there is a depression in the weld to not hurt the base metal as the standard,
It is strictly forbidden to polish the surface with a diagonal shovel at the end of the blade.
Technical requirements: the polished surface shall be smooth; Does not hurt the base metal, the base metal is not removed more than 0.2mm as the standard; Part of the table to be polished
Surface grain requirements are consistent, along the direction of the weld, irregular grinding is strictly prohibited.
3. Remove surface scratches
Grinding range: take a rectangular frame to cover the scratched area.
Operation method: Use a grinding tool to grind along a certain direction, no more than the rectangular box.
Technical requirements: the polished surface shall be smooth; Does not hurt the base metal, the base metal is not removed more than 0.2mm as the standard; Part of the table to be polished
Sheet metal processing surface pattern requirements are consistent, large parts and oven body horizontal drawing direction, small parts along the drawing direction and keep the same; Irregular grinding is strictly prohibited.
4. Polishing of machining residual height
Grinding range: 40-50mm on both sides of machining residual height.
Operation method: grind along the direction of the vertical bar being processed, and grind with Angle mill in the space where the Angle mill can be used; The space that the Angle mill cannot use is polished by the direct mill; The method is the same as the grinding of weld residual height.
Technical requirements: the polished surface shall be smooth; Does not hurt the base metal, the base metal is not removed more than 0.2mm as the standard; The surface grain of the polished part should be consistent.
5. Polish with an emery cloth wheel
Polishing range: polishing the edges and corners of small spaces such as line holes or parts with polishing requirements.
Operation method: Use a straight grinding machine with an emery cloth wheel to polish edges and corners.
Technical requirements: the polished surface shall be smooth, a visual
inspection shall meet the requirements of drawing annotation, and touch
sensation shall not have sharp edges and corners as the standard; Does not hurt
the base metal.
