We know that ordinary lathes are now more and more difficult to meet the needs of processing precision parts, but gradually replaced by CNC CNC lathe locks, then the CNC precision parts processing process standards are like? The following is introduced by us for everyone:
Precision Machining - Process Standards for CNC Precision Parts Machining
On a lathe, the shape and dimensions of the blank are changed by using the rotary motion of the workpiece and the linear or curved motion of the tool, and it is processed to meet the requirements of the drawings.
At the same time, the price of CNC machine tools has been declining due to the increase in production levels. CNC precision parts processing includes ultra-precision turning, mirror grinding and grinding.
The premise of CNC precision parts processing is the accuracy of its process reference. The benchmarks on mechanical drawings are represented by uppercase letters A, B, C, D, etc. with a specific circled reference symbol. When the surface of the reference symbol and the extension line of the surface or the dimension of the surface are aligned, the indication is based on the surface. When the reference symbol is aligned with the dimension line, it is based on the physical centerline of the dimension. The accuracy of the process mentioned earlier is a more general point.
Assembly reference refers to the precision used to determine the position of a part in a part or product during assembly. The measurement reference refers to the standard used for the size and position of the machined surface to be measured during the part inspection. Positioning reference refers to the reference used to position the workpiece in the machine or fixture during machining.
