TRAVEL PATHS OF THE BASIC MACHINE
Machine stand horizontal-longitudinal X = freely selectable (2,000-20,000 mm)
Headstock slide vertical Y = 4,100 mm
Headstock horizontal-transverse Z = 1,600 mm
MACHINE FRAME X-AXIS
Intrinsically rigid design as the basis for dynamic and vibration-damped movement of the machine column in the X-axis. Three hardened compact roller guides ensure maximum precision when moving.
MACHINE STAND Y-AXIS
Stand made of welded steel construction with compact roller guides. Two hardened compact roller guides guarantee the transmission of high cutting performance with consistent quality.
HEADSTOCK SLIDE AND HEADSTOCK
Cast construction made of GGG 60 with hydraulic weight compensation, guided on the machine column with 2 hardened compact roller guides. Headstock also made of GGG 60 cast iron with two opposing compact roller guides. The long guideways both to the machine column and to the headstock guarantee maximum power transmission with consistent quality. To prevent the machine column from tilting, the guideways of the Y and Z axes are arranged as close as possible.
CONTROL

DRIVE SYSTEM
Digital individual feed drives for contour-accurate work via AC motors with constant torque, feed and rapid traverse range infinitely variable from: X + Y + Z – axis 2-18,000/12,000/15,000 mm/min
MEASUREMENT SYSTEM
Direct non-contact measurement via linear measuring systems for high-precision production.
SECURITY ACCESS
The rear area of the machine must be secured in accordance with safety regulations. A safety switch is provided for this purpose. Protection (fence + access door) is provided by the customer. The safety switch is installed by SHW. Optionally, the entire safety system can be provided by SHW.
Access behind the machine is only possible when the machine is switched off.
