Stable milling options for cemented carbide

One of the difficulties with the ageing VMCs was the Stainless Steel Casting inability to mill by circular interpolation a sealing surface without four quadrants being visible and lines apparent at each change of axis direction, with the attendant risk of parts being rejected. coolant system, has proved itself easily capable of achieving the drawing tolerances when machining nickel and steel alloys.Features of the Wele that secure a combination of heavy cutting performance and precision finishing include two-speed, auto change gearbox drive to the Whitehouse on the  table has plenty of room at one end to accommodate it.LB Bentley’s operations manager。

We have been extremely pleased with the performance of our new machine. It is very rigid and the load monitor highlights that the machine can easily cope with the materials and depths of cut specified. So these machines should be well set to take us into the future, regardless of what the industry throws our way.Our machinists have commented how quiet the machine is when cutting at high torques and low speeds, 1,500rpm being a maximum here when milling our difficult alloys.With limited factory space here, the small footprint of the Wele is supporting our 5S initiative and the continuing improvements we are making on our shopfloor. LB Bentley looks forward to receiving a second, identical machine this Spring.Machine shop supervisor Tracey Harnden was part of the team tasked with sourcing the new capacity .

We shortlisted two alternatives to the Wele and asked both potential suppliers to run a trial using one of our existing programs for cutting an Inconel part. The spindle stalled on one machine, while the other company were unable to point us to a single user installation where their equipment cuts our type of alloys.Other CNC mills we looked at were light, high-speed models that were obviously unsuitable and the original supplier of the VMCs that are being replaced did not even call us back.Mr Harnden says that Whitehouse carried out the cutting trial on LB Bentley’s material using the program and tooling from Stroud for the designated part, which initially needs rigorous fly cutting across the top of the billet.He witnessed the demonstration at the supplier’s technical centre in Kenilworth and noted the quietness of the process due to the machine’s rigidity and hence low levels of vibration.

The latter attribute contributed also to the required accuracy of machining and surface finish being achieved.sher Business Park in Stroud, part of the Severn Glocon Group, has identified an ideal platform for producing its subsea valves, and also its filter and dryer equipment, from tough materials.It is the AA1165 VMC with 1,100 x 650 x 600mm working envelope built by Toyoda joint co-operation company Wele. One was installed at the start of January 2019 and a second is due for delivery shortly. The sales and service agent in the UK and Ireland for the Taiwanese machine manufacturer is Whitehouse Machine Tools, Kenilworth.Although LB Bentley’s existing production equipment has served them well, the company wanted initially to replace two VMCs with new machines capable of meeting the tight positional tolerances and surface finish required when producing components from a range of difficult materials including.
