Operations of the L20 Cincom VIII Swiss Screw Machines

Enhancements to the Cincom L20 VIII (for those interested in the technical aspects of the L20 VIII machine.)

  1. Description: Sliding Headstock CNC Automatic Lathe. On a sliding headstock machine, all operations are performed within an eighth of an inch from the machine's guide bushing. With the distance between the bushing and tool minimized, and with whirling's minimal chip load, pressure on the workpiece is minimized, eliminating the risk of bowing and deflection during the production of bone screws and other medical machined parts.

  2. More live tool power: The Live Tool Motor on the gang plate has been upgraded from 0.75kw (1HP) to 1.0kw (1.33HP). This enables heavier machining for the tuff materials used for bone screws and other medical machining parts. (titanium and 316L)

  3. More Tools and flexibility on gang tool post: By utilizing the triple cross live tool spindle, the total number of cross live tools on the gang slide can be increased to 7. By simply rotating the triple cross live tool spindle 90 degrees, 4 cross-live tools and 3 front face live tools are possible. By utilizing the double end face live tool spindle, 4 cross live tools and 3 front and 3 back face live tools are possible.

  4. Higher machine rigidity: Larger and heavier axis slides combined with improved live tool clamping system have increased the machine's total rigidity.

  5. More tooling flexibility: It is also possible to replace a cross live tool spindle with a double or triple stationary I.D. tool holder. Also the live cross spindles on T6 and T7 can be switched to turning tools by replacing them with optional turning tool adapters.

  6. Capabilities include Contouring, Threading, Milling, Slotting, Cross Work. Cross Work includes Drilling, Off Center Drilling, Tapping, Reaming. End work capabilities include Milling, Drilling, Tapping, Reaming, Boring.

  7. Reduced cycle times (less cost to the end user), user-friendly operation and easy maintenance.

  8. High Pressure Coolant CBBL with Heat Exchanger.

  9. Whirling Unit and Cutting Head. Consists of two components, a cutting head that contains the cutting inserts, and a whirling head that mounts the same way as a cross drill in a live tool station. High precision parts, such as bone screws, other threaded surgical implants, and other medical machining, can be produced from rough stock at high speeds in a single pass. By adding the Whirling attachment as a non-dedicated machine tool, the multi-axis turning, milling and drilling versatility of the machine are not compromised.

  10. With the whirling attachment the cycle time to produce a typical bone screw is cut in half.

  11. Canned Cycle for Drilling.

  12. Main and Back Spindle Synchronization.

  13. C Axis Main Spindle

  14. Back Spindle Index 1 Degree.
