Multiple cycles for automaticsurface grinding operations.

DGTplus is available for rotary table grinding machines.

The system is ideal for achieving high productivity when machining one-off, smalland medium workpiece batch sizes.

Equipped with powerful and advanced software, DGT Plus can be used to link grinding cycles, with shaped grinding wheels. It will also carry out shoulder grindingand many other options, all using simple and guided programming, appropriate forexperienced and inexperienced operators alike.

The control is housed in an ergonomically positioned operator console whichcomplies with all current applicable standards.

- DGT Plus makes using shaped grinding wheels simple thanks topowerful and clear graphics.

- The most commonly used grinding wheel shapes are included in the Standard Grinding Wheel Library. To define the geometric features, simply fill in the values of the table for the required grinding wheel.

- Grinding wheel shapes Maximised versatility

- Shoulder Grinding Minimised Operator Intervention

- Continuous downfeed cycle

- With DGT Plus you can carry out particularly problematic machining like shoulder grinding in automatic mode.

ddggttccnncc Simple to use CNC control

- The Power of control

In FAVRETTO philosophy, Power of Control is an essential factor for success.

Power of Control - the use of the latest generation SIEMENS numeric control power allows advanced application software.

- it allows inexperienced operators to create and use formed wheels through extremely powerful graphical templates.

- It offers an easy and effective solution to all technical challenges with the simple combination of work cycles and the forming of wheels.



ddggttccnncc

- Guaranteed reliability

In FAVRETTO philosophy, Guaranteed Reliability is an indispensable factor for success.

Guaranteed Reliability- is a result of the use of "reliable" materials, components and systems. - it consider's the machine tool as an element of the productive system, including the

operator and the environment.- it foresee's and solve's those situations representing a threat to the

productive system. - it also means:

Maximum comfort for the operator.Availability of an easy solution for each problem.Maximum operator's satisfaction for the results obtained by their work.

18


- Functional technology

In FAVRETTO philosophy, Functional Technology is an important factor for the success.

Functional technology - makes the operator experience simple. - makes advanced grinding cycles simple to achieve.- makes changing a wide variety of parameters easy to

achieve which enables maximum optimisation of any work cycle.
