CITIZEN L20-VII

The CINCOM L-series has been specially developed for high-precision manufacture of simple and complex parts in medium to large batch sizes. It offers all-round versatility with its many variants, flexible options and extremely short setup times. All axis movements and even the opening and closing of chucks are implemented by servo motors. As a result, actuation times are reduced by around 50% by comparison with conventional CNC lathes which rely on hydraulics/pneumatics for auxiliary functions. Built-in servo motors require less space and minimise the occurrence of faults.

• All round CNC sliding head turning centre for up to 20 mm diameter.
• Maximum stability and operational life.
• Fully CNC servo-controlled, eliminating hydraulics and pneumatics.
• Fast cycle times with considerably reduced setup times.
• Maximum production with low capital input for a rapid return of investment.
• Good swarf disposal.
• Y-Axis as standard

• Long parts adapter
• Parts conveyor

The main and sub-spindle drives are equipped with highly dynamic built-in motors. The main drive, for example, accelerates to the maximum speed of 10,000rpm is less than 1 second. This is an extremely important advantage when positioning the spindle for milling or when changing the direction of rotation for threading.

All movements, including chucking, are carried out by means of intelligent, digital AC servos. Elimination of hydraulics and pneumatics dramatically increases reliability and minimises maintenance requirements.

Due to the extremely compact design of the drive technology, no additional electrical cabinet is required. All components are integrated into the machine.

By incorporating this advanced technology, limit switches are no longer required and it is not necessary to zero return axes when switching on the machine.

For complex external machining there are 6 turning tools with 12x12mm tool shank available. In addition, there are 4 driven tools and 3 tools for front machining. The L20-VII is equipped with sub-spindle and a drilling tool post with 3 stations. Numerous other tool combinations are available as options, so that for example, even eccentric drilling and milling operations on the front or the back side of the workpiece are possible.

This configuration, which includes a "Y" axis on the main tool platen as standard, makes the L20-VII an extremely versatile and powerful machine tool.

The L20-VII provides a total of 16 tools:

• 6 (7) turning tools
• 4 driven tools
• 3 tools for front machining
• 3 tools for back machining
