Detailed Specification

WHN9-CNC/25, WH10NC-CNC/25 – Horizontal Boring Mill – Table Type

This document covers the machine types WHN9A, WHN9B, WHN9C, WHN10NC ca. to the year 1990. After the overhaul, they all have the same design and differ only in details.

Features

  • contouring horizontal boring machine
  • fixed column, crosswise travelling table
  • 4 linear axes, rotary table
  • sliding workspindle
  • machine designed for universal application in engineering production
  • suitable for roughing as well as for finishing
  • optionally can be fitted with tool magazine with manipulator (ATC), tool cooling kit (CHZ), cooling through spindle axis (CHOV) or oil-mist cooling

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 wall inside the operator housing
  • the control system allows manual, semiautomatic and fully automatic modes
  • 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 TNC 640 + handwheel
  • HEIDENHAIN drives
  • SIEMENS motors

Powered Axes

  • X – travel of rotary table slide on saddle
  • Z – travel of saddle on 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
  • gear set + gear ring

Group Guidance

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

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
  • spindle cavity blown with air during tool-changing cycle
  • spindle driven by four mechanical range – gears
  • hydraulic shifting of each range
  • headstock balancing – ropes and counterweight led in column
  • setup of tool cooling by jets on headstock front side

Hydraulic Power Pack

  • HYTOS hydraulic and lubrication set
  • lubrication of all axes
  • clamping X, Y, Z, B
  • unclamping of the tool

Position Measurement

  • HEIDENHAIN digital optical measuring
  • X, Y, Z axes – absolute linear encoders
  • W axis – absolute rotary encoder in motor
  • B axis – incremental angle encoder
  • S axis – incremental rotary encoder

Energy Distribution

  • IGUS chain energy carriers

Coverage of Machine

  • complete coverage of guideways of X, Z axes
  • partial coverage of Y axis

CE – valid only for the European Union

  • comprehensive safety elements according to the applicable legislation and technical standards
  • operator housing
  • working area of the machine is fenced off

Optionally

 

Control System

  • SIEMENS SIN 840D SL + handwheel
