Milling development cuts machining costs
by 50%
The introduction of a close pitch milling cutter is instrumental in increasing surface speed and reducing machining times by as much as 50% in medium and finish machining applications in steel.
The introduction of WNT's A4900-09 close pitch milling cutter is instrumental in reducing machining times by as much as 50% in medium and finish machining applications in steel In this particular case the customer is taking advantage of the additional cutting edges (10 instead of 7) to increase table feed by 100% from the current 646mm/min to 1299mm/min

Close pitch milling cutter ups feeds by 100%
Taking advantage of additional cutting edges (10 instead of 7) to increase table feed by 100%, a close pitch milling cutter can reduce medium and finish machining times in steel up to 50%.
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.
Surface speed is also increased, thanks to WNT's CWX 26 carbide grade that has been developed specifically for steel cutting applications.
A further benefit is the fact that the number of components machined per set of insert edges is increased by around 20%.
The basic concept behind the A4900-09 range is one of the maximum number of cutting edges for all diameters of cutter.
In achieving this WNT is helping to maximise the productivity and profitability of its customers.
The entire range uses the same SDMT 09 size of insert, with variety being provided by the three styles of chipbreakers - including the brand-new '-29' geometry and a choice of five carbide grades.
These grades cover most ferrous machining applications while for non-ferrous applications WNT has provided the 27 geometry.
Each insert has four effective cutting edges as well as a wiper facet for improved surface finish of the workpiece.
The combination of pocket and insert design also ensures an exact 90 degree corner angle for shoulder and slot milling applications.
Available as threaded shank, DIN1835 or shell mill-type cutters, the A4900 -09 range is available from 25mm diameter with three inserts through to 100mm diameter with 10 inserts.
For heavy-duty milling applications WNT offers its range of A4900-12 cutters, which are designed to machine at depths of cut up to 12mm.
"This product is going to dramatically improve the cost-effectiveness of many milling operations," says Adrian Fitts, business development manager at WNT (UK). Request a free brochure from WNT (UK) ...
"It is still very new to the UK but, the results that we are witnessing exceed all our expectations, with customers reporting significant improvements over their existing milling systems.".
