VARNSDORF WHT 130C high-performing machine centre
The new high-performing machine WHT 130 is a horizontal boring machining centre suitable for the most demanding operations that require precise boring, threading, vertical lathing and/or milling. The WHT 130 may be additionally equipped with a wide choice of accessories, which will satisfy the needs of even the most demanding applications.
Maximum machine dimensions: X – 5 000 mm, Y – 3 000 mm a Z – 3 000 mm
Two types of central headstocks:
• 4 000 ot / min, 41 kW, 3200 Nm
• 5 000 ot / min, 41 kW, 1718 Nm
Thermal compensation of the machine
A wide choice of clamping devices.
• Rotary table with capacity up to 10 000 kg.
• Up to 4 automatically changeable palettes.
• Carousel table with a diameter of 2 000 mm a 250 rpm.
Linear guideways in X, Y and Z axes ensure a high accuracy and strength of the guide with a very low friction coeffi cient.
The basic parts of the frame (tables, palettes, longitudinal and transverse beds) are made of the highest quality grey cast iron of Czech origin.
High feed speeds in X, Y, Z: 25 000 mm/min and 36 000 mm/min.
Either SINUMERIK 840D sl and HEIDENHAIN TNC 640 control system can be selected for controlling the machine.
