Technical specification

(technical specification v14.05)

The RET100B is a contouring table type of a horizontal boring machine designed by the company RETOS VARNSDORF s. r. o. It is an option to the manually operated machine W100A.

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 (CHM)
  • ready for „Industry 4.0“ 

Controlling of the Machine

  • all functions of the machine, except for 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 supplemented by a portable control panel (handwheel), which duplicates some basic of the 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 a connection with the Ethernet for easy administration and distribution of technological programs, machine operation monitoring, diagnostics or servicing of the control system etc.

Machine design can be customized.

Standard 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 out 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
  • technological possibilities may be limited by territorial implementation of the NC program of the control system 

Kinematics of the W Axis

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

Kinematics of the X, Y, Z Axes

  • W axis – sliding guideway, cast-iron / steel
  • B axis – guideways of the rotary table are scrapped, cast-iron/TURCITE

Lubrication

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

Clamping

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

Headstock
