CNC Control


For our production series instead of our BZT CNC-USB-Software respectively BZT CNC-Servo control we can also offer you CNC-Control technology from Siemens or Heidenhain. For example from Siemens we can offer the Summerik 802S, from Heidenhain the TNC320.

BZT CNC-USB-software

The software BZT CNC V5 USB is designed for the use of an external CPU to the CNC-Control. The data transfer of the controlling unit takes place via the USB interface. By sharing the tasks the system even functions with higher speeds without any dropouts. While BZT CNC V5 USB does its work, you can use CAD/CAM applications and other programs without any problems.  The function „Look-Ahead-Feed“ calculates optimal paths and provides an excellent speed behaviour. Particularly the G-code generated by CAD/CAM with many short linear pieces profits from this function.
Here you can find our BZT-CNC-USB software in the shop!

Simple CAD/CAM functionality

  • DXF
  • HPGL
  • Milling / cutting
  • Engraving
  • Drilling
  • Pocket milling

Tool data

  • Tool length
  • Tool diameter
  • Length compensation G41, G42, G43
  • For rotary tools there are available additional adjustments for
  • X-Offset and tool orientation

Simple installation

  • Selection of the visible axis x, y, z, a, b, c
  • Number of steps per MM
  • Machine program
  • Maximum speed and acceleration per axis
  • Movement speed, direction, position
  • Play compensation.
  • Interpolation mode for A-axis, 4-axis milling, 4-axis cutting, styrofoam cutting, standard rotation axis.
  • Lookahed feed angle optimisation
  • IO-Modi and inversion
  • Jog buttons inversion for machines with a moveable bed.
  • PWM mode for the control of the spindle rotation speed
  • Storage file for the digitisation password in order to avoid adjustement changes by the machine opeator
  • Hand wheel parameters adjustment
  • Freely selectable editor (for example Notepad ++)

BZT CNC V5 USB has enlarged G-code functions

  • # Variables
  • sub - endsub, gosub (subprograms)
  • while - endwhile
  • if - else - endif
  • Mathematicl functions
  • Operator access on the G-code via the function „msgdlg“. With this function the creation of own macros is possible.
  • Automatic tool change, which can be programmed as a macro by the operator, too.

SINUMERIK 802S base line control

The CNC from Siemens for applications in the lowest cost segment offers, thanks to the following three features, the optimal solution in the technologies lathing and milling:

  • Extremely simple operation
  • No maintenance
  • Unbeatably inexpensive

The SINUMERIK 802S base line is constructed on maximal three stepping drive control axis and an analogue spindle. We deliver a control panel with all necessary components: NC, SPS, control panel, machine control panel, inputs, outputs and software.
