SANKYO bronze is easy to machine. Basically, there is no great difference between the machining of our products and normal steel. No special tools are required but be sure to use sharp and preferably new tools.
The use of cooling lubricants is recommended by using HSS or carbide tools. First pre-roughing to approx. distance of 0,3mm to nominal. In general: Milling / rough machining with little effort, slow forward feed, at high rotation-speeds and small depths of cut.
The use of cooling lubricants is recommended by using HSS or carbide tools. Drill as with normal steel and if it´s necessary increase the forward feed with same rotation-speed. Flat plates have to be drilled from backside and countersink on the sliding surface if it´s necessary to drill through a solid-lubricant depot.
The use of cooling lubricants is recommended by working with grinding wheels.
