Customers often ask: can we make sure that we can process according to their drawings? Can accuracy be guaranteed? Can tolerance be guaranteed? Here, you can be careful to answer you,
1.Shape
The deformation is within 0.002, and the deformation of small parts is within 0.005.
2.Tolerance
All dimensions should be positive and negative.
The overall dimension must be within 0.001, and the cumulative tolerance profile should be guaranteed at 0 position.
The dimension tolerance should be the middle value.
If there are text requirements, they shall be processed according to the text requirements.
The size of the same position in different directions shall be within 0.002, and there shall be no platform.
There should be no bell mouth, step and groove side.
The fitting arc must be machined according to the tolerance, and the forming arc should be within 0.01.
The size of the hanging platform shall not be higher than that of the forming surface.
3.Right angle
Three direction inspection, the right angle of parts is guaranteed to be 0.002.
4.Clear angle
Fit position and small parts clearance angle less than 0.03. Forming position is generally below 0.05.
5.Deformation
After the process is completed, the deformation is detected in three directions and controlled within 0.002.
The height shrinks or expands in the direction of the tab.
Check the deformation of discharge molding position.
6.Finish
The finish should be fine, no obvious sand damage and no scratch on the surface.
There should be no carbon deposition in the discharge, the lines should be processed according to the smoothness comparison table, and there should be no bench mark on the discharge interface.
Wire cutting shall be free from corrosion and rust.
7.Appearance
The parts shall be free of bruise, tread angle, collapse edge, explosion edge and burr.
8.Missed processing
Mark the processed size on the original drawing with a fluorescent pen and record the processed size truly.
At last, the shape is confirmed by comparing with CAD and 3D, no missing machining is allowed.
All departments need to communicate with each other in time for the processing of public places.
