Gühring’s extensive range of threading products includes the Pionex threading line

Gühring’s extensive range of threading products includes the Pionex threading line. The fluteless and cut machine taps have been developed to reduce axial forces and torque by up to 30% whilst improving surface finishes and tool life.

The Pionex machine taps covers over 85% of the industry applications. The Pionex Series includes 45 degree helix geometry with a reduced rake angle, back tapering and improved relief. All this culminates to provide unprecedented performance and swarf removal. With a H6 shank tolerance for use in all types of clamping chucks and the forming tap that has a lubricating groove to improve thread formation, the next generation Pionex is an impressive threading prospect for any machine shop.

Pionex fluteless taps are manufactured from a powder metallurgical steel material that demonstrates a high wear resistance. A special surface treatment in combination with the Gühring established TiCN-coating furthermore ensures a longer tool life. With fluteless tapping the surface finish of the tool is of significant importance as it is a cold forming process. Thanks to a new polishing process the surface could be homogenised and made even smoother. Overall the optimisations are reflected in a longer tool life and improved surface finish quality.

“The biggest issue with tapping is always swarf control and more taps break through poor swarf control than for any other reasons. This is particularly the case in retraction when the tap is in reverse. The biggest challenge is always to make the swarf fall away from the tap rather than get wrapped around it and we’ve certainly achieved that with the new Pionex,” said Gühring.

The Pionex range is manufactured from HSS-E or PM30 with Gühring’s new aluminium nitride or zirconium coating technology. The diverse capabilities of the Pionex range through its innovative swarf controlling geometry means that this new Pionex range can be applied effectively to 85% of targeted applications that range from standard low carbon steels to the tougher steels and stainless steels. For exotic materials, Gühring have a very diverse range that caters for all types of heat resistant alloys.

The Pionex is available with metric threads in course or fine pitch as well as UNC, UNF, BSP in all diameter and pitch variants with a complete line of special thread designations also available upon request.
