A high resolution uStepper Driven tangentially controlled axis turns a Tungsten Carbide (Widia) cutter. The Widia cutter is precision ground on a 6-axes CNC-grinding machine with utmost precision. This cutter is universal and can be customized if required. The special C-axis motor has a hollow shaft with a push rod connected to a variable speed oscillating drive motor. The oscillating frequency can be infinitely varied between 0 and 6000 cycles/min. to allow cutting of thick materials with a standard low-cost replaceable blade. The prefered cutting depth is easily adjusted over a range of +/- 8.0 mm by turning a precision micro-stop by hand. Cutting depth is maintained by the nose piece which is made of low friction POM material. This setup assures optimal cutting even over large and uneven surfaces. An optical encoder is provided for homing the tangential tool with standard CNC-homing instructions. All connections to the CNC-controller and power supply are available at the DB9-male connector provided. This Direct Driven Tangentially Controlled Cutter comes with its own Z-axis slide for FLOATING cutter usage on your machine. As standard the Z-axis slide has recirculating ball bearings. For extreme precision a roller-bearing option is available. If the optional dedicated Z-axis motor with backlash free ballnut leadscew is ordered, you can precisely control the Up/Down movement of the cutting tool. This unit provides very fast response with precision landing of the tool for extended life time of the cutter. Also, the float feature is fully preserved. An additional feature of the Z-axis drive is control of the pressure (vertical load) on the cutting blade. By positioning the Z-axis motor against the bottom stop and providing more or less "overrun", a spring is compressed against the cutting head assembly. This has the effect of adding weight to the assembly. This ensures easy programmability of cutting performance in many materials and at various feed rates. The Z-axis drive motor has its own DB9-male connector, identical to the C-axis, and an optical encoder to home the Z-axis with standard CNC-controller commands.

If electronics options are ordered power supply's (230 VAC) and electronic drive(s) for the axes as well as the oscillating mechanics are included.

Automatically generate 4-Axes G-code for EMC2

With our tangentially controlled tools we supply proprietary post processors, drivers and utilities for automatic building and sorting closed contours, correcting overlap or gaps, adding Z-safety, Z-up and Z-down parameters as well as deciding when and where to lift the tool depending on the angle of enclosed corners. Once everything is setup according to your preferences, generating the proper G-code for any DSP CNC-controller (G-code compatible with EMC2) takes only a few F-keys or mouse clicks. All software is pre-installed in a click-and-run VMWARE player image on a protected Xplot-firmware USB-stick included in the price and delivery of this product.
