Milestones of innovation

Pneumatically actuated micro percussion tool with up to 10mm increased distance compensation for marking uneven panels

As an option, the engraflexx ESP is now also available with automatic tool change unit

Deburring tool with integrated distance scanning unit for milling precise chamfers on uneven panels

A pneumatically driven marking tool type with an integrated print setting. With the gravostar HRY- 20 PP the required marking depth can be precisely positioned on the tool and set with an accuracy between a few hundredths of a millimetre up to a few tenths of a millimetre.

A direct drive deburring tool which deburrs by the combined action of a router bit and brush. This combination enables workpieces made from hard materials to be deburred with process reliably and complete freedom from secondary burr.

Based on the principle of the engraflexx LC, further versions have been developed: for deburring on rear, as well as front and rear edges of any undefined workpiece contours.

After a test period of more than two years the patent was granted for the axially deflectable engraflexx LC tool type

Market launch of the world’s first volume production of a deflectable deburring spindle with individually adjustable lateral deflection force driven by a high frequency spindle motor.

The development and market launch of the engraflexx LC series makes a further tool version available for the automatic solution of corresponding problems in deburring and final machining on CNC machines. An application was filed for the principle of this tool at the same time.

A micropercussion tool with integral pressure reduction to achieve a precisely adjustable marking depth was developed in the form of the gravostar WSRX-20 following an enquiry received from a power train manufacturer.

After the previous premises became too small the company moved to Oberuzwil where the company had found an ideal site in a former shoe factory.

The world’s first deburring tool with spindle deflection driven directly from the machine spindle was launched in the form of the engraflexx EC. A genuine innovation for the deburring of undefined edges on CNC machines.

The patent for the hydraulically driven (i.e. using the coolant) micropercussion tool was granted just under two years after application was filed.

The first hydraulically operated needle embossing tool for CNC machines was presented as a world first at the tool trade fair in Sinsheim. Only a few months after the official presentation of the needle embossing tools, Daimler was acquired as the first major customer.
