WEILER CYCLE-CONTROLLED PRECISION LATHES Cost-effective and efficient for one-off and small batch production. As simple as an engine precision lathe and as versatile as a CNC lathe. For general mechanical engineering, tool, jig, fixture and mould making, the energy and environmental sector, medical engineering, the extraction industry, maintenance and repair workshops, as well apprenticeships and vocational training. The advantages of cycle-controlled precision lathes: • Rapid implementation from the drawing to the finished workpiece • Optimum ergonomics and accessibility for the operator • Extremely short set-up times • Generously sized working areas with a minimum footprint • Increased acceptance criteria ensure the highest possible precision of the turned parts
