Global stainless steel round steel market dynamics

This report focuses on Stainless Steel Round Bar volume and value at global level, regional level and company level. From a global perspective, this report represents overall Stainless Steel Round Bar market size by analyzing historical data and future prospect. Regionally, this report focuses on several key regions: North America, Europe, China and JapanKey companies profiled in Stainless Steel Round Bar Market report are One of the difficulties with the ageing VMCs was the 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.

Quality is paramount, with  dimensional accuracy and 0.4mm Ra surface finish required.The machine, fitted with a high pressure  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  spindle, which delivers up to  of torque, hand-scraped square-section guideways, rigid construction, up to 10m/minute cutting feed rate and table has plenty of room at one end to accommodate it.Bentley’s operations manager Andrew Kethro comments: “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.
