Tool grinding machine TTB Engineering SA

The TGC is a Tool Grinding Center built for the realisation of high precision tools. The 4 or 5 grinding spindles can have 1 to 3 grinding wheel each. The possibility to have up to 15 grinding wheel at disposal, allows a flexibility and a guarantee to make any kind of tool in one working process. The machine shows all its quality in the micro tooling, where it's able to make tools with a diameter less than 0.04 mm, with surfaces hardly alike A special hydrostatic system for the axis moving allows a very precise positioning, with a backlash inferior to 0.0004 mm and a longer lasting life compared to the classic elements of competitive machiners. The particular kinematics unusual for grinding machines, allows a large working flexibility.

The Model TGC (Tool Grinding Centre) has been developed for the production of high-precision tools. The overall excellence of the machine occurs in the grinding of Micro-Tools. Tools having diameters in the range of 0.02 mm to 14 mm are ground in optimal Quality. Resharpening is also possible for tools having diameters upwards to 25 mm.

The heart of the machine is the spindle turret, consisting of 4 spindles (optional 5). Each spindle can be equipped with up to 3 different grinding wheels.
This feature provides the machine with important advantages:
* All required grinding wheels are always and instantly ready for use in the machine.
* The selection of the grinding wheel is performed in seconds.
* Absolute accuracy in positioning and repeatability.

The tools can be ground in one clamping and with the highest degree of precision.
