Thread milling range from Dormer Pramet offers multiple benefits
Dormer Pramet has launched a comprehensive thread milling program to provide a reliable and versatile threading option.
Available under the Dormer brand, each of the new cutters is recommended for machining most materials, including steel, stainless steel, cast iron, titanium, nickel, copper, aluminium and plastics.
An Alcrona Pro coating and solid carbide substrate provides a tough and wear resistant structure, offering security and reliability, as well as increased performance and longer tool life.
A total of ten versatile milling cutter (J2xx) families have been developed with a mix of popular thread forms including, M, MF, UNC, UNF, G (BSP) and NPT, with or without internal oil feed.
Thread milling offers numerous advantages compared to conventional threading, including increased reliability, smaller chips – supporting continuous machining – improved tool life and accurate tolerance adjustment, whilst it is also suitable for dry machining.
The same cutter can be used for many materials and diameters, as long as the pitch is the same, while Dormer’s J200 and J205 ranges offer the additional possibility to chamfer, providing better quality and accuracy compared with conventional taps.
Ricky Payling, Dormer Pramet’s application specialist for rotary tools, said: “Thread milling is a relatively slow process with measurable time savings on larger diameters. However, the quality of finish and level of accuracy can greatly compensate for the speed of machining.
“The new range of thread milling cutters provides numerous options for the end-user, whether it’s left or right hand internal threads for the vast majority of thread forms and for any material.
“A controlled machine that can make circular paths is required, but our online product selector will suggest the most appropriate thread milling cutter with the relevant data and CNC programme, to make the choice as easy as possible.”
The introduction of the thread milling cutters is part of a wider product launch by Dormer Pramet on 1 April 2015 – the first combined unveiling since Dormer and Pramet merged last year.
