Variable pitch milling cutters raise
productivity
Variable pitch geometry, solid carbide milling cutters have a number of features that benefit end-users with increased metal removal rates in steel and, therefore, enhanced productivity.
As the latest addition to its Plus range of tooling, the solid carbide HPC milling cutters from WNT (UK) display a number of features that benefit end-users with increased metal removal rates and, therefore, enhanced productivity Thanks to the variable pitch geometry that reduces natural harmonics, the use of extremely tough sub-micron grain carbide and the development by WNT of the silver coloured, chromium-based Ti 1010 coating with an HV hardness of 3600, cutting speeds of up to 250m/min and feedrates up to 0.55mm/tooth are achievable when cutting steel

Precision boring tools perform roughing, finishing
Precision modular boring tools provide users with roughing and finish boring capability through an extensive range of modular couplings and extensions.
Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
In addition to the increased cutting speeds the HPC range also benefits from extended tool life due to the reduced harmonics and the flute design that allows high swarf removal rates even at large depths of cut and elevated spindle speeds.
From an operators perspective the design also leads to an extremely quiet machining cycle.
The combination of the new Ti 1010 coating and the variable pitch geometry also has an advantage when using machines with low-powered spindles.
The extremely soft cutting action reduces the power requirement allowing feeds to be used that would not be possible with conventional milling cutters.
The range currently encompasses seven styles of cutters including a tool for roughing and finishing grooves from solid material, peripheral milling, pocketing, ramping and helical milling in steels and cast irons; A rough milling cutter for universal application but, with particular suitability for machining titanium and similar materials; Radius copy milling cutters; and a range of finishing cutters that feature an eccentric ground relief that provides extraordinary stability and quiet operation.
The success of HPC is highlighted by one particular customer that is machining flame-cut mild steel components.
Since working with, Shaun Thornton, WNT's Technical Sales Engineer, it has increased its productivity, producing the same machined feature in 45s, compared to the previous best of 3 min.
The time taken to finish mill the same feature has been reduced from 45s to 15s.
