What is the economic processing accuracy of CNC machine tools?
The machining accuracy of machine tools is the actual geometric parameters after machining parts, but we must correctly understand the economic machining accuracy of the company's equipment. The so-called equipment economic processing accuracy refers to the mechanical processing, the appropriate clamping measuring tools, the level of workers equivalent, reasonable time quota can achieve the tolerance grade.
1. Tolerance grade and surface roughness that can be achieved by lathe machining holes (hole depth is not more than 3 times of diameter)
A drill hole (aperture ≤80) can achieve the tolerance grade IT12~13, surface roughness 12.5
Drilling - reaming - reaming tolerance grade IT8~7, surface roughness 1.6
2, thread machining economic accuracy
The tolerance grade of thread processed by die is 6H~8H, the tolerance grade of internal thread tapped by tap is 4H~7H, the tolerance grade of external thread is 4H~6H, and the tolerance grade of internal thread is 5H~6H
3, the outer cylinder surface processing route and can achieve tolerance grade and surface roughness
Rough lathe can achieve tolerance grade BELOW IT11, surface roughness of 25~12.5
Semi - finishing turning can achieve the tolerance grade IT7~8, surface roughness 6.3~3.2
Fine turning process can reach the tolerance grade IT6~7, surface roughness 1.6~0.8
Grinding tolerance grade IT5, surface roughness 0.8~0.4
Fine grinding can achieve tolerance grade IT2~5, surface roughness 0.4~0.2
