The Model #750 McLean Lathe is a 3-axis production machine. This unit finds it's place in the job shop or production plant where several different jobs will be run on it. You may find that some of the simpler jobs you have run on your CNC lathe could be run more economically on a McLean #750 and let the CNC lathe do the more difficult jobs. Replace the standard Tail Slide with the optional Heavy Duty Box & "L" #10-550 Tail Slide and increase the flexibility to include internal O-ring grooves and internal contours with form tools. Also, the relieving action can be used to eliminate withdrawal marks. The controller has No cams or tapes, and it's not a computer that requires programming.
