C.N.C. Automatic Base Curve Lathe

A feature of the machine is that it can produce a base curve which has an accurate diameter with a pre determined land width to prevent chipping at the edge. The machine incorporates a pneumatically controlled collet and the computer can be programmed to produce any required quantity of base curves automatically The precision build of the lathe and the high quality of the spindle balance ensure base curves which require a minimum of polishing and thus retain their geometric integrity. Suitable for hard, soft and gas permeable materials.

The C.N.C. Base Curve Lathe is an automatic machine which will produce either single radius or lenticular base curves. With cycle times as low as 45 seconds possible, and minimal operator attention the machine is ideal for stock or small batch quantity prescription production. The lenticular topslides are manually set. The lathe is computer controlled and incorporates an automatic button loading and unloading system.

Control System for both Front and Base Curve C.N.C. Lathes The CityCrown CNC Lathes are fitted with a standard PC, replacing the old Epson HX20 computer, and programmed in Basic. This enables users quickly and simply to adapt the standard programmes to their own particular production method and requirements. It is also possible to load the machine control computer via a second computer; several CNC lathes can be controlled from an in house computer system.
