Custom CNC Machining of a Cast Steel Spade Lug

(click on thumbnail to enlarge)

CNC Machined Cast Steel Spade Lug created for the Mining Industry

This large spade lug was custom CNC machined for a manufacturer of mining equipment. Made from cast steel, the lug measured 14" in length, 3.25" in width, with an outer radius of 23.1875". Milling of this part required the design and fabrication of a special cutter, which was composed of 4140 heat treated steel, and utilized carbide inserts to cut the required 28ᵒ angle on a 23" radius. The machining was performed on our BMC50 vertical CNC mill and included contouring, angle milling, drilling, and tapping. We have produced 200 of these spade lugs per year for 15 years.
