HORIZONTAL DEEP DRILLING LATHES BASIC PARAMETERS Max. torque on spindle Max. weight carried berween centres Max. length of the drilled holes Max. diameter of drilled holes The WT1 80 horizontal deep drilling lathe is a machine tool based on the TRB 93 horizontal lathe equipped with devices that facilitate drilling and machining of deep holes with the use of highly-efficient, specialized tools. PURPOSE The WT1 80 horizontal deep drilling lathe is designed for deep hole drilling, external and internal turning, reaming and contour thread cutting. CONTROL SYSTEM The application of the state-of-the-art CNC system allows for automatic, precise and efficient workpiece machining according to a program. MAIN FEATURES Machine tool construction based on a rigid bed with hardened guideways Bed and headstock bodies made from high-grade cast iron of enhanced mechanical properties Carriage travels along two V-block guideways that guarantee precise guidance Bed and carriage guideways hardened to 50 HRC Longitudinal and cross-wise travels along two guideways lined with an anti-friction material and assisted by central lubrication system Spindle rested on bearings of increased accuracy class All shafts and gears carburized, hardened and ground Drilling tool coolant supply head on an independent floor Drilling carriage with tool bar clamp with sleeves for different diameters Dampening rests for the tool bars to compensate for vibrations during drilling Tool liquid cooling system for drilling with a 2,500 l tank
