Video: Micromilling With a Long Tool
Video shows milling a deep slot with a 0.8 mm diameter tool. Machining conditions are 40,000 rpm, 1,181 ipm and 0.1 mm depth of cut. Video courtesy Delcam.
This video provided by CAD/CAM supplier Delcam shows milling a deep slot with a tool 0.8 mm in diameter. Machining conditions are 40,000 rpm, 1,181 ipm and 0.1 mm depth of cut. For more on milling at extreme tool length-to-diameter ratios, see the video under “Editor Picks” at right.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
