JIS G3114 SMA58W Material Machining Technology
Coolants are also important when machining JIS G3114 SMA58W steel as they can effectively reduce the heat generated by the cutting process and keep the cutting edge sharper for longer. Generally, a light emulsion or oil-based coolant should be used. Heavy concentrations of coolant should be avoided to prevent clogging in the cutting tool.
