McLean Model 850

Production & Second Operation Lathe

In the spectrum of lathes, from hand operated to CNC, we feel we’ve developed an affordable compromise.

Versatility & Efficiency

Taking a lathe with a 9” swing, we’ve added air powered slides with a controller to operate the movement of the collet, spindle, and each slide. This allows an unskilled operator to make thousands of parts with greater speed and accuracy than with comparably

priced lathes. With the versatility of the McLean System, you have an effective alternative to higher-priced equipment.

 

3 axis production lathe

This machine is well- suited for dedicated applications or can be changed over to run multiple parts.

The Model 850 can be placed alongside of a CNC lathe, screw machine or molding machine to allow the operator to perform a second operation. The Model 850 is standard with a Front Slide, Rear Slide, and a Tail Slide. Other slides, including our heavy-duty slides, are also available. McLean slides are air-powered with hydraulically controlled feed.

The controller features a Touch Screen and PLC. The controller operates the sequencing of the slides, spindle RPM & direction, and duration of operation. It provides program storage for six different parts and includes Total Cycle Counter.
