WRD 130/150 (Q) - Product description

WRD 130 and 150 plate horizontal boring machines represent a twin-type of machines of the same concept and frame, but different main motor outputs, different headstocks and spindle revolutions. The machines are intended for precision and high-efficient coordinate boring, drilling, milling and thread-cutting particularly in the case of large-scale, heavy and structurally difficult work-pieces made of cast iron, cast steel and steel.

WRD 130 / 150 (Q) are plate horizontal boring machines of a left-had design with a tail-stock barrel (sliding block) and telescopic working spindle. The machines are continuously controlled in four axes (X - base cross travelling, Y - headstock vertical adjustment, Z - sliding block longitudinal travel and W - working spindle longitudinal travel). Either Heidenhain iTNC 530, Sinumerik 840 or Fanuc control system can be selected for controlling the machine.

The main drive as well as all others drives for the machine axes are digital AC types of Siemens.

The modular conception of the machine allows the user to choose the optimum design meeting the user's technological requirements from many variants of the machine. Depending on the travel of the X and Y coordinates, the user selects the operating area arrangement consisting of UD 4 clamping plates and the configuration of one or more rotary tables. The technological performance of the machine may be considerably expanded by the use of special technological accessories.

Producer offers the product in these options:

WRD 130 - horizontal boring mill with a tail-stock barrel (sliding block) and telescopic working spindle. The machine, after prior agreement with the manufacturer, may be equipped with additional rotary table S 25 (S 16, S 40) controlled by machine control system.

WRD 130 Q - the same product equipped by automatic tool change which consists of the chain tool magazine, tool handler track on the base and handler itself fitted with a swinging double arm.

WRD 150 - horizontal boring mill with a tail-stock barrel (sliding block) and telescopic working spindle. The machine, after prior agreement with the manufacturer, may be equipped with additional rotary table S 25 (S 16, S 40) controlled by machine control system.

WRD 150 Q - the same product equipped by automatic tool change which consists of the chain tool magazine, tool handler track on the base and handler itself fitted with a swinging double arm.

The working spindle rev drive is derived from the electric control drive over a two-speed gearbox. In the gearbox, two mechanical gears are automatically engaged - by an electrically controlled shifter. The working spindle is nitrided and it is push-fit with a minimum clearance into a nitrided hollow spindle with bronze bushing in its front. The hollow spindle is fitted into the pre-stressed spindle ball bearings.

The machines are equipped with a platform. The platform bears the control system panel and it is vertically adjustable.

UD 4 clamping plate is designed as an optional technological accessory for making possible to clamp exceptionally large and heavy workpieces or additional workpiece holders.
