Tos Varnsdorf WRD 170 Q floor type horizontal boring mills

Floor type horizontal boring machine with a sliding ram and sliding spindle WRD 170 Q represents a new type of floor type horizontal boring machines manufactured by TOS VARNSDORF. WRD 170 Q machines are designed to serve for precise coordinate drilling, boring, milling, and thread cutting. They are particularly suitable for the machining of box  plate- and complex-shape workpieces made of cast iron, cast steel, steel or other materials machinable with cutting tools, and for large and very large size and weighty components. The machines can be completed with an accessory table, or possibly with two rotary tables and a clamping field composed of clamping plates. The machines can be extended with a wide selection of technological accessories that significantly widen the machine technological utility value. Basic design options of these machines are defined by the work cycle automation level: WRD 170 - basic design WRD 170 Q - machine design allowing Automatic Tool Exchange ATC

COLUMN The column body is a steel weldment. Toothed racks for Y-axis drive, a telescopic hydraulic cylinder for the headstock mass balancing, and two ways for the headstock travel in Y-axis are mounted there. High part of column is prepared for possible inside installation of vibration absorber. HEADSTOCK The headstock has a parted body the inner part of which bears a robust ram fitted with electro- mechanical deformation compensation at the ram extension. RAM OF THE WRD 170 Q MACHINE WRD 170 THE BED is made of grey cast iron. Three linear guideways and a toothed rack for the column slide traversing in X-coordinate are screwed up from the top of the bed. ELECTRIC OUTFIT OPERATOR PLATFORM An electric cabinet placed on a shop floor, outside the machine. As a standard, the machines are houses electrical accessories except for actuating and switching equipped with an operator platform elements. It contains a basic control system module, components movable vertically and horizontally in direction of the spindle. Machine control panel is placed Electric box is cooled with unit which is built into the door on the operator platform. of this box. COLUMN BODY COMPENSATION BED-COLUMN-HEADSTOCK Weight of the headstock is compensated by the power of telescopic hydraulic cylinder. Source of pressurized oil comes from a system of pressurized vessels placed on the column saddle. All control systems in standard design include: Basic module control central Color LCD display unit Control panel with keyboard Portable control panel with electronic handwheel Functions and equipment of the control systems that can be added: Measuring touch probe Interface enabling remote diagnostics As a standard, the machines are equipped with HEIDENHAIN iTNC 530 machine control system. As an option, the machines can be equipped with SINUMERIK 840 D SL

The control system fully continuously controls linear coordinates and eventually positioning of the rotary table B axis. In case of continuously controlled milling head installation or other optional equipment requiring continuous control, these axes are also continuously controlled. The control system enables

simultaneous interpolation: linear circular spiral helical SYSTEM OF MEASURING The linear axes X, Y, Z are equipped with direct measuring with the use of sealed HEIDENHAIN electro-optical measuring rules. HEIDENHAIN iTNC 530 HSC1 FANUC
