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.
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.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
