CITYCROWN MANUAL LENTICULAR LATHE

The CityCrown Manual Lathe is the most widely used machine in the Contact Lens Industry and is well known for its reliability and robustness. The Manual Lathe is available in two options: Single Slide (Ref No: 5000-0001) and Lenticular Compound Slides (Ref no: 5000-0002). The Manual Lenticular Lathe is also available with a single slide radius cartridge.

The lenticular lathe fitted with the double top slide assembly is capable of producing the two lenticular curves in one pass giving a smooth transition. These craftsman-built hand-operated lathes are designed to meet high standards of contact lens manufacture.
They are suitable for producing high precision specials or they will readily fit into a production flow line. Each machine has a variable spindle speed up to 9000 rev/min. The spindle and motor are both dynamically balanced and during manufacture, when the machine is fully assembled, it is balanced en masse to eliminate vibration throughout the speed range. These lathes can produce both concave and convex surfaces using hard, soft and gas permeable materials.
