Detailed Specification

WHN13-CNC/33 - horizontal boring mill – T type

These specifications cover all machines from the series WH13, WHN13A, WHN13B, WHN13C c. up to 1990 which are of the same concept after reconstruction and differ only in the details.

Features

  • contouring horizontal boring machine
  • cross-shaped beds
  • 4 linear axes, rotary table
  • sliding workspindle
  • machine designed for universal application in engineering production
  • suitable for roughing as well as precision contouring
  • optionally can be fitted by tool magazine with manipulator (ATC), tool cooling kit (CHZ), cooling through spindle axis (CHOV), oil-mist cooling (CHM) or swarf conveyor

Controlling of the Machine

  • all functions of the machine, except tool clamping and unclamping, are controlled via the control panel, which consists of a keyboard, a switch panel and a LCD monitor
  • the tool clamping and unclamping is controlled by switches on the headstock
  • the control panel is completed with a portable control panel (handwheel), which duplicates some basic functions of the control of the machine
  • the control panel is rotary situated on operator platform placed in front of the headstock
  • the control system allows manual, semiautomatic and fully automatic modes
  • in case the machine is fitted with the automatic tool changer (ATC), the extra hand-held ATC control panel is needed. This is used when the magazine is loaded.
  • the standard communication interface allows connection with Ethernet for easy administration and distribution of technological programs as well as diagnostic or service works of the control system

Basic Version

Control System

  • HEIDENHAIN iTNC 530 HSCI + handwheel
  • HEIDENHAIN drives
  • SIEMENS motors 

Powered Axes

  • X – travel of rotary table slide on transversal bed
  • Z – travel of column slide on longitudinal bed
  • Y – vertical headstock travel on column
  • W - spindle travel
  • B – table rotation
  • S – workspindle rotation

Machine Capabilities

  • X, Y, Z, W axes powered in interpolation
  • B axis powered only positionally
  • linear interpolation of four axes
  • circular interpolation of two of four axes powered in interpolation
  • spiral interpolation
  • spacial interpolation - spline in space
  • interpolation of S and Z (W) axes - spindle turning depending on the Z (W) axis position - enables thread cutting without use of a compensating bushing
