Technical specification

(technical specification v14.03)

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.


  • 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.

  • 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
