Easiest Way To Halve, Yes Halve. Your Cycle Times
On Thursday 8th July MILLMAX was tested at an MSC customer in Swindon, Wiltshire. The task was to improve tool life, surface finish, reduce scrapped parts, free up machining throughput and remove a lapping operation.
MILLMAX was tested on a Mori Seiki SH 50, BT40 back end and a 63mm diameter face mill with a gauge length of 250 mm. The tool tested was used to rough mill a face.
The component is a valve casting and the customer produces over 1,000 parts per annum on site but sub contracts out a further 3,000 castings. The existing cutting data was RPM 1,000 with a feed rate of 900 .
As a result of using MILLMAX we increased the RPM to 3,063 and increased the feed rate to 1,875. This resulted in chatter being reduced significantly and provided a better surface finish. The surface finish is now superior to the finish produced by the finishing face mill. In addition to improved surface finish and a reduction in scrap the existing cycle time of 14 minutes was reduced to 7 minutes.
Should you wish to explore MILLMAX in greater detail please reach out to myself or any of the MSC Engineers mentioned in this post.
