Detailed Specification

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

This document covers all the machines types WH13, WHN13A, WHN13B, WHN13C ca. to the year 1990. After the overhaul, they all have the same design and differ only in details.

Features

  • contouring horizontal boring machine
  • crosswise-joint beds
  • 4 linear axes, rotary table
  • sliding workspindle
  • machine designed for universal application in engineering production
  • suitable for roughing as well as for precision contouring
  • optionally can be fitted with 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 an 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 swivellingly connected to the operator platform in front of the headstock
  • the control system allows manual, semiautomatic and fully automatic modes
  • the standard communication interface allows a connection with the Ethernet for easy administration and distribution of technological programs as well as diagnostics or servicing of the control system

Standard Version

Control System

  • HEIDENHAIN TNC 640 + 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 stroke
  • 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

Kinematics of the X, Y, Z, W Axes

  • brushless digital servomotor with servo-drive
  • clearance-free gearing by timing belt
  • ball screw

Kinematics of the B Axis

  • brushless digital servomotor with servo-drive
  • planetary gearbox with minimum clearance

Group Guidance

  • X, Z axes – guideways are reinforced with hardened steel plates, counterways casted by plastic, jibs are lined with TURCITE 
  • Y axis – guideways are reinforced with hardened steel plates, counterways and jibs are lined with TURCITE 
  • W axis – sliding guideway, cast-iron/brass/steel
  • B axis – guideways of the rotary table with plastic casts

Lubrication

  • central, axial lubrication
  • frequency of lubrication cycles correlates with travelled track of the particular group

Clamping

  • X, Y, Z, B axes – hydraulically
  • W axis – not clamped – positional feedback

Headstock

  • sliding workspindle
