The Centauro model T90E CNC lathe is a sophisticated, yet simple to use machine that eliminates the need to turn components from either a template or master sample. The machine has 4 axis CNC control, the X axis for the tool carriage, Y axis for the finishing gouge, V axis for the roughing gouge and A axis for the spindle rotation (when optional spindle inverter is fitted). This precision control ensures excellent quality and definition of the turned component. The T90 is supplied with the CT CAD software package which enables profiles to be quickly and easily created on a PC, laptop or on the OSAI machine controller which has a 15" colour touch screen with user friendly interface. Features of the CT CAD software include:
- Possibility for multi pass cutting layers on specific areas of the turning that may require heavy stock removal or have a deep profile.
- Possibility to make a finishing cut on the return stroke of the tool carriage.
- Polyline for the creation of curves via multi point plotting.
- Programming of the dowel knife (which can be used on the same turning up to 20 times) to come in before, during or after the turning operation.
- Each profile created can be given a product name or code so it can easily be recalled in the future.
- Transfer of created profiles on remote PC or lap top via USB key.
The machine incorporates as standard two main cutting gouges for turning that are mounted opposed to each other, one for roughing and one for finishing with the programmable back knife mounted on a revolving tool turrent. Also the positioning and movement of the tailstock is controlled by the CN. The unique hydraulic automatic self centering system comprises of a centering cup and steady rest for accurate high speed loading of components upto 100mm sq. As the device is activated by a foot pedal control, the operator is left with both hands free to load the component. For sections larger than 100mm sq. and upto 178mm sq. a set of special detachable vee blocks are used to centre the component. Production can be monitored on the machine controller which gives the cycle time to produce the individual component and the total number of components produced. If required it is possible to enter the specifc number of components that are needed, once this figure has been reached the machine will stop.
Due to the machines ease of setting and programming (no changing of samples or templates) it proves ideal for economically producing short batch runs of many different designs of turnings thus reducing work in progress and stocking costs. It also has the unique ability to save in product development time and cost by fast prototype design and production which can be done while the machine is still in operation.
