623 posts. Location:KC. Posted March 13, 2003. Hi all, We are starting to work with some beryllium copper in our shop, and are pretty inexperienced with machining of this material. If somebody with experience could suggest speeds and feeds for drilling and tapping, with both carbide and high speed drills, I would be very grateful.

An investigation has been made of the machining damage induced in beryllium by surface grinding. A series of damage free specimens was prepared from a bar extruded from a block of hot-pressed beryllium powder. Each specimen was then ground on one large surface using a different set of grinding conditions, as dictated by the requirements of a quarter-replicate …

OD/ID Grinding. OD/ID grinding is a machining function that is used when a customer's design has a tighter tolerance on the OD and/or ID profiling than can be met by pressing alone. The part is OD and/or ID ground to meet specifications. This type of machining can also apply any form, including threads, to tolerances as low as 0.0001". CNC Milling

Grinding. The essence of metal grinding is that the metal surface of the workpiece is grinded, which is extruded by innumerable abrasive particles instantaneously and produces deformation under the action of friction, and then turns into wear debris and forms a smooth representation process. It is mainly used for the gear bore after heat treatment.

Abstract. This paper investigates the machinability of Cu-Be alloys by ultraprecision grinding and facing. The material temper, tool geometry, and machining parameters are varied to assess their effects on surface finish. The study shows that microgrinding of Cu-Be with a diamond wheel generates a rougher surface finish as compared …
