Birchwood Casey recently delivered two of its Tru Temp CNC automated finishing lines for low temperature black oxide finishing. One system is being used for finishing motion control and power transmission components. The second is being used to finish firearm-related components. Both systems employ the latest automated finishing technology for environmentally friendly, fast part finishing without the addition of labor.

According to the company, the latest automated system incorporates a programmable hoist that moves components through the Tru Temp 200° black oxide process in a 28-min cycle from start to finish. The safe and simple process contains no EPA-regulated compounds and usually requires no waste treatment of process rinsewaters. The CNC-controlled process line is designed to produce consistently high quality black oxide finishes, with minimal labor input, thereby streamlining workflow patterns and meshing smoothly with ISO and JIT programs.
