How to Hit ±0.01 mm Without Paying Premium Brand Prices
Every purchasing manager faces the same equation: tighten tolerance or tighten budget-rarely both. Last month a Polish job-shop proved it is still possible to do both by switching the finishing station of a 316-L shaft from a coated end-mill to Cutoutil's CM915 carbide insert in a 32 mm U-drill. Same spindle, same CAM program, only the insert and feed rate changed. Cpk moved from 1.33 to 1.67 while cycle time dropped 12 %. The secret is not magic; it is a 0.4 µm AlTiN polish that reduces built-up edge and lets you push speed 15 % higher without extra heat. The insert costs 18 % less than the tier-one brand they used before, and because we stock 120 000 pieces in Changsha, the lot arrived in Gdańsk in 4 calendar days-no air-freight premium charged. If you are running stainless, Inconel or hardened steel below 45 HRC and need repeatable ±0.01 mm, test the CM915 on your next Monday shift. We can ship free sample inserts against your existing tool holder; just tell us the IC and corner radius you use. Email cutoutil@hanvitools.com with "CM915 sample" and your shipping address, and see the numbers on your own machine before the end of the week.
