The self-reversing tapping attachments for high-production tapping on CNC machines are claimed to provide very short cycle times. Eliminating machine spindle reversal means longer tap life, the company points out. The power required and the wear to the machine are also reduced.

The Synchro-Flex tap holders for synchronised tapping utilise a special flexure that provides excellent micro axial compensation. The devices are claimed to improve thread quality and tap life by 100 per cent and more. A high-pressure, high-volume internal coolant is standard for capacities M1 to M48.

Three different options for marking the workpiece on the CNC machine are being presented that serve to eliminate secondary operations. The Tap-Writer dot peen marking tool provides fast marking of characters, logos or data matrix codes. The new Scribe-Writer marks hard or soft materials and uneven surfaces and the marking head tool stamps the workpiece in less than a second using custom or standard stamp types.
