INFORMATION
The SR-20J type C sliding head lathe is ideal for small length-to-diameter ratio parts. Production costs for short-turned parts are further reduced through the lack of a revolving guide bush, therefore greatly reducing remnant lengths.
A total of up to 30 cutting tools are still available including 14 power-driven tools for cross drilling, milling, slotting and angular hole machining. The new 2 position deep drilling station allows drilled holes up to 10mm diameter by 100mm deep to be carried out on the main spindle.
The fully independent sub spindle has a full C axis and coupled with polar co-ordinates creates a virtual ‘Y’ axis thus enabling the machining of hexagon, square or other profiles.
BENEFITS
- Full 20mm Bar capacity in both Main and Sub spindles
- Six Turning Tools
- 6 Front End working tools
- 4 Independent Rear end working tools (8 static or 6 driven)
- 5 Driven tools as standard (up to a maximum of 14)
- ‘C’ Axis standard on Main spindle and Sub spindle
- Maintenance free Linear Guideways
- Fully independent Sub-spindle
- 35 mpm Rapid Traverse
- Independent deep hole drilling Spindles – Main spindle
- Shorter Remnant Length
