Leadantimony is harder than pure lead but it is still soft. I use leadantimony alloy for casting bullets. Go down to a hardware store and buy a box of solid brass nuts, not plated, and use them in the mill. They''re readily available in a variety of sizes, relatively cheap and they will do the job.
These two aspects lead to residual compressive stress on highspeed ballend milled surfaces of hardened AISI D2 steel, as shown in Fig. 6. With the increase of a e, more energy was consumed and more cutting heat was generated during highspeed ballend milling process.

Dec 02, 2011#0183;#32;In general, hard milling involves cutting primarily tool steel or precipitation hardening stainless steel, such as 155 or 174, that has been hardened to at least 50 HRC. After a workpiece is roughed in the soft state, it is sent to the furnace for hardening and then finish machined with coated carbide, ceramic or PCBN tools.
Oct 01, 2013#0183;#32;1. Introduction. High speed machining (HSM) of tool steels in their hardened state is emerging as an attractive approach for the mold and die industry since machining and polishing take up more than 50% of the total production time .Significant cost saving and productivity improvement can be achieved through HSM compared with the traditional method where workpieces go through rough
