Speeds and Feeds <strong>HAHN</strong>REITER HSS-E Surface Speed m/min 2 4 6 8 10 12 14 18 20 R.P.M. Calculating R.P.M. and Feed Rates for CNC Machines Tension and Compression (Floating) Attachment Do not programme to feed in and out at 100% Pitch This can cause tight threads, rapid wear and breakages. We recommend to set at 95% Pitch R.P.M. = Surface Speed x 1000 FEED = Pitch x R.P.M. x 0.95 3.142 x Dia Example: Tapping Stainless Steel M10 x 1.5 (Recommended surface speed 6.0 metres/min) R.P.M. = 6 x 1000 FEED = 1.5 x 190 x 0.95 = 270mm/min 3.142 x 10 This has the following advantages:- TAP DIA. MM Rigid Tapping Higher machining speeds possible. Repeated tapping of the same thread. Increased traverse range of the spindle axis due to absence of floating tap holders.

Basically, you either programme your machine spindle to feed in and out at a given pitch, or multiply your pitch by the RPM to give you the exact feed rate. This will vary according to machine tool manufacturers. However, with rigid tapping, should you encounter problems of excessive tap breakage even with using the correct geometry tap, we suggest you revert back to the use of a floating holder for a comparison. 8 UK +44 (0)1376 347566 Email: enquiries@fenntool.co.uk Website: www.fenntool.com Ireland +353 (0)45 877740
