Advanced Engineering Stand E23
The machining of high value components across various industry sectors is a growing aspect of the UK manufacturing economy which creates challenges for production engineers. At WNT (UK) it is working to assist these engineers with the introduction of new, high performance, cutting tools such as its Type W solid carbide cutters for alight alloy machiing; as well as placing increased emphasis on applications support by providing a dedicated team of Applications Support Engineers to work alongside customers to develop the best machining strategies.
The new Type W solid carbide cutters from WNT (UK) have been designed for the high performance machining of aluminium and other light alloys and are proving popular with those machining components for the aerospace sector. Part of that popularity is down to the fact that the cutters are available with corner radii specific to that sector, as well as ball nose cutters, all available as standard for next day, before noon delivery. The Type W cutters are also available in a variety of geometries specifically created for the machining of non-ferrous materials, typically found in the aerospace sector.
The range includes two styles of ripper cutters, one with a geometry aimed at pure roughing operations, featuring a round chord profile and special grind that generates small swarf chips that can be easily evacuated from the cutting area with the aid of the standard through tool coolant supply, while the end geometry of these cutters is designed with plunging operations in mind. The overall cutting characteristic of these roughing cutters is the soft cutting action and reduced vibration, which allows feed rates to be maximised even on thin-walled and unstable workpieces. The second ripper geometry is capable of both roughing and finishing operations and features a reinforced core and flat spiral design to the flutes. Swarf control has also been addressed with this design by the addition of chipbreakers to ensure maximum chip control, even in long chipping materials. In addition to the ripper cutters the main body of the range features a variety of cutter styles including 2,3,4, and multi-flute cutters all with geometries deveoloped for cutting light alloy and non ferrous materials, and feature different helix and rake angles accordingly.
There is also a choice of two coatings, TI1005 is a multi-layer coating suitable for HPC (High Performance Cutting) techniques and for even greater wear resistance there is the option of WNT’s DLC (Diamond Like Carbon) coating, which has an extremely high hardness rating of Hv 0.05, equivalent to 60-80 per cent that of diamond and a very low co-effcient of friction equal to 0.1 in comparison to steel. It is also an extremely thin coating that allows for a much sharper cutting edge. However, for those that need an even sharper cutting edgethere is the option for uncoated cutters.
With the ongoing introduction of new cutting technologies WNT has also invested in a specialist team of Applications Support Engineers to further enhance its already market-leading customer service offering. This team of highly-skilled engineers will be available to work on specific projects with customers and develop optimum machining strategies. Working with customers in this way can lead to significant productivity gains and reduced consumable tooling costs. A key benefit of this new team is that they can take the strategy development off-site to WNT’s technology centre in Sheffield. In doing this work can be done in the background while the customers production is not interrupted by cutting tool trials or NC program development on their machine tools.
While having access to the WNT Technology Centre, this team of Applications Engineers is field based with engineers located across the UK, so they are able to respond to customer calls as efficiently as possible. “Customer service and high performance cutting tools have been the foundations of WNT’s success and with the development of our Applications Support Engineering team we are now taking that customer service to a new level. In the short time that we have had the team in place we have already seen customers benefit greatly from their input and, we are confident that this team will grow as more customers take advantage of the knowledge that we have to share with them. At the same time WNT continues to introduce new and improved cutting tool technology and the Type W cutters are just one example of how we are developing our product range to meet the changing demands of the metal cutting industry,” says Glenn Stanton, UK & Ireland Sales Manager, WNT (UK).
