I would like to ask stainless steel milling with 3mm milling 3MM WIDE 10.5mm long, 10mm deep keyway, the amount of knife, feed and speed of each dozen, what kind of material is best to use milling cutter?
It is better to use carbide coated milling cutters. If the high-speed steel milling cutter, it is useless to estimate the 1 workpieces to be milled. If you feed, you can slow down, wait for stability, and then pick up. After all, the diameter of 3MM milling 10MM deep, it is still difficult. Speed, you can call 4000~5000. I can make special stainless steel milling cutter. QA
High precision requirements, it is recommended not to use 3mm milling cutter, can not ensure that the groove width, depth, 10mm is relatively deep, generally 3mm blade length of up to 9mm, this also needs attention.The general material can be, but the knife to do a sharp point, using large front angle, small core thickness of the design tool, the next knife Z=0.2-0.3mm, F=600-1000, speed about 5000. These are theoretical values for reference only and are subject to actual processing.
The processing of stainless steel materials, of course, is the use of YG type carbide cutting tools are the best, such as YG8, etc., if the use of ordinary high-speed steel milling cutter to process stainless steel materials, knives are very durable. With such a small cutting depth, generally in the 0.1 ~ 0.2mm, the feed speed of about 20mm/min,./min in 800 ~ 1000. In general, engagement should be small, feed to slow, the diameter of the cutter is small, speed is not too low. Plus, add coolant.
