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.
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of the Ti 2000 PVD-multilayer coating used on WNT's Blueline range of solid carbide milling cutters This extremely hard (Hv0.05 = 3500), heat resistant and low friction coating, when combined with WNT's 'ultra sub-micron grade' K10 - K30 carbide substrate, is providing tool life double that of competitor tools

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 offer stable high feed per tooth usage
Among several advantages offered by indexable insert and solid carbide milling cutters is an insert seat that provides support and excellent stability in high feed per tooth applications.
Another benefit of the Ti 2000 coating is the extreme smoothness of its surface when applied.
This leads to improved surface finish on components.
Other features of the Blueline range are the specially developed cutting geometries, which are tailored to the machining of hardened materials.
The main cutting edge features a zero degree rake angle.
The level of precision grinding is evidenced by the guaranteed accuracy of the cutter radius of +/-5 micron and the variance of the machined profile, which is within 10 micron.
The range is available in long or extra-long series as parallel end mills ranging in size between 6mm and 20mm diameter - all featuring two cutting edges that meet in the centre.
A ball nose variant is also available between 0.25mm and 20mm diameter.
A typical application of Blueline example is where a 62 HRc steel is cut, under dry conditions, using conventional and climb milling techniques.
A solid carbide 12mm diameter ball nose cutter with two cutting edges had a tool life of 42 minutes, and the actual length of cut was 44.4 m with a resulting wear pattern that measured just 0.28mm (0.18mm after 31.5 minutes in cut).
The cutting data used was 153m/min surface speed and 1060mm/min feedrate with a depth of cut of 0.3mm.
As with all WNT products delivery of cutters from the Blueline range is guaranteed for noon of the following day, if ordered before 6:30 pm. Request a free brochure from WNT (UK) ...
