Cutting tool producer WNT (UK) plans to make the most of its time at MACH by launching several new cutting tool products, unveiling its latest catalogue, and extolling the virtues of its Tool-O-Mat tool vending system – a cost-effective method of providing 24-hour access to tools, seven days a week. Cost savings through using Tool-O-Mat are typically between 10-20%, according to WNT. The risk of carrying stock is transferred from the customer to WNT as, in effect, it becomes a consignment stock, being invoiced only when it is used. This also delivers a major reduction in purchasing costs with only one consolidated invoice per month. Among the new products on display on WNT (UK)'s 250m² stand and also in action on the XYZ Machine Tools' stand will be the new WTX Speed series of solid carbide drills, WTX Change drills, Master-Mill A2780 milling inserts, High Feed Drills, and the HCX1125 turning inserts. WTX Speed solid carbide drills are capable of drilling at speeds up to 240m/minute due to the design of their asymmetric point geometry and WNT's new Ti800 coating with no perceived loss of tool life or hole quality. Ideal for machining steel and cast iron, the WTX Speed drills are delivering productivity gains of around 60% compared to existing solid carbide drills and, with WNT's Restart regrinding service they can be reground with the original geometry and recoated to further extend their value. The WTX Change series of replaceable head drills now features drill head grades capable of machining stainless steel and aluminium components. Furthermore, the range has been extended to drill holes up to 8x diameter as standard items. These extra long drills complement the existing 3x and 5x drills already in the series, with diameters ranging from 12mm to 32mm. Master-Mill A2780 is a series of indexable inserts that is helping to drive down manufacturing costs, especially for the high performance, 45° approach milling sector. This is due in part to the tools featuring eight edges per insert and also their 15mm edge length, with federates of 0.45mm/tooth at a depth of cut of 6mm not uncommon. The geometry of the inserts also creates a much softer cutting action. Indexable insert drilling is catered for by the WNT High Feed Drill, which features square inserts in place of the more familiar Trigon-shaped insert. The benefit of this is the ability to increase federates and generate increased metal removal rates. For example, typically feedrates for conventional indexable insert drills are between 0.075mm/revolution and 0.14mm/revolution. By changing to the square insert this is increased to by almost 100% to between 0.14mm/revolution and 0.225mm/revolution. HCX 1125, WNT's new steel turning grade is also delivering improvements in performance thanks to the development of a completely new carbide substrate combined with WNT's Mastertool Dragonskin coating technology. In some cases, tool life is improved by a factor of five, with ten times not being uncommon when compared to existing grades. WNT (UK)
