CNC system delivers automated black oxide finishing

Birchwood Technologies offers the CNC TRU TEMP® finishing system. The nonpolluting, low-temperature process is available in an integrated programmable hoist and tank line to process iron and steel components automatically with a black oxide finish.

The self-controlled tank line eliminates the labor costs typically required with manual hoist lines. The CNC process line eliminates process guesswork and generates repeatable results. The standard, 110-gal. tank line system produces 4,000 to 6,000 lbs. of finished parts per 8-hour shift, and the line can be sized and configured to accommodate any volume of work or production capacity.

The CNC can process up to three part loads concurrently, for a maximum throughput of about five loads per hour. The hoist and superstructure, which can be built to handle any size load, are operated by an Allen Bradley PLC digital control with a touchscreen panel and manual joystick backup. The hoist locates itself along the process line by means of a rack-and-pinion driveline, combined with setdown saddles on each tank.
