---------------------------------------------------------------------

SPINDLE BOX
- Powerful main motor with high drive power and low bend speed for plenty of power even in the lower speed range
- Large spindle bore
- Oil circulation lubrication with separate lubrication unit for the main spindle bearings
- Two-stage gearbox in the headstock, manually or optionally automatically switched
- Coolant collection tray at the rear of the main spindle with coolant return into the chip tray

MACHINE BED
- Guides hardened and precision ground

BED SLIDES
- Bed slide guides plastic coated
- Guides and taper bars precision-scraped for high continuous precision, finest oil pockets
- Central lubrication with metering piston distributors on all guideways and the preloaded ball screws

PLANSCHLITTEN
- Guides made of GG and finely scraped
- Long, continuous, scraped wedge bar
-Aluminium link apron as cover at the front of the cross slide

AXIS DRIVES
- Digital drive motors with integrated absolute measuring systems mean that no reference point travel is necessary after switching on the machine

RIDING STOCK
- with lateral adjustment
- Roller guide for easy sliding of the tailstock on the bed

MACHINE COVER
- Two (three for larger centre widths) separate safety doors for optimum covering of the working area and at the same time very good accessibility
- Left safety door with function as chuck guard
- Safety doors pulled down low, completely covering the doors behind the lower guide shaft support
- Safety screens in sandwich construction with polycarbonate inlay reliably protect the operator from ejected parts
- Additional panelling (machine closed on the right) e.g. as complete panelling when machining non-ferrous metals, higher coolant pressures or for better efficiency in conjunction with a workspace extraction system
- Movable safety doors

OPERATING UNIT
- Combination operating unit with ergonomically optimally arranged machine operating panel and control (utility model protection 20 2004 009 351.0) 2-fold guided in ball bushings
- very good handling and good accessibility to the working area when changing workpieces and tools as well as for special machining technologies

ACCURACY
- high accuracy due to high-quality components such as precision ball screws and measuring systems

The machine is offered with a 12-month warranty from HR Werkzeugmaschinen GmbH.
