Drum Lathe TDM-1200
The Kugler Drum Lathe TDM-1200 is a multi-axis system with aerostatic bearings, specially developed for ultra-precision turning of optical microstructures on rollers with the use of diamond tools. The center distance on this model amounts to 1200 mm.
Mono-crystalline diamond tools with defined geometric cutting edges produce smooth optical surfaces, or annular and helical groove structures on work pieces made of non-ferrous metal or coated with electroless nickel.
An optional Fast Tool Servo allows for the turning of uneven structures. The system meets highest demands on roughness and geometrical accuracy (concentricity, diameter variation, cylindricity).
The TDM-1200 is characterized by a solid granite construction, vibration isolation by using special air damping systems, aerostatic rotary bearings in headstock and tailstock, and aerostatic mounting of the carriage assembly (Z-axis).
The axes Z and Y incorporate high-definition incremental measuring systems and special direct drives for positioning within submicrometer range. This design principle guarantees utmost accuracy in high-precision chip removal.
A wide selection of accessory components complements the system, such as hydrostatic axes for tool rotation, Fast Tool Servo (FTS), tool setting microscopes, and optical sensors for distance and diameter measurement.
