We are releasing a machining case study of 【super hard alloy direct engraving】! We drilled a φ2, 90° tapered hole on the end face of a round bar made of super hard alloy, Sumitomo A1 (HRA91.4). This time, we used Union Tool's diamond-coated tools. Compared to the finish of electroplated tools, the surface is finished much more beautifully.

A φ2, 90° tapered hole was drilled into the end face of a super fine particle super hard alloy, Sumitomo A1 (HRA91.4) round bar. This time, a diamond-coated tool from Union Tool was used. Compared to the finish of an electroplated tool, the surface is finished quite beautifully. ◇ Material used: Carbide, Sumitomo material A1 (HRA91.4, Co content 13%) ◇ Tool: Union Tool UDCB2006-0042, 2-flute ball end mill R0.3 x 0.42 ◇ Machine: ROKKO Smart Technology Android 2 ◇ Conditions: Spindle speed 30,000, feed rate 200
