progress through courage and perseverance
Milestones of innovation
The pioneer has the courage to leave the well-trodden path. He is prepared to overcome long periods of hardship and even accept failure.
The reward: The accumulation of priceless experiences and acquisition of enormous know-how. This often leads him to become an innovation leader and an undoubted expert. This is the way we decided to go – so that we could always offer our customers the best solutions.
Development of the gravostar HRY-20 PP
May 15, 2019
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 in the range from a few hundredths of a millimetre to a few tenths of a millimetre.
Introduction of the gravostar WSXP
May 15, 2018
A specific customer application was once again satisfied with the development and launch of the gravostar WSXP-20: the application of deep markings on un-machined castings plus the added requirement that the marking still had to be easily legible after painting.
Exhibited for the 5th time at the EMO in Hanover
May 16, 2017
Gravostar was exhibited for the 5th time at the EMO in September 2017. In October of the same year it was also exhibited for the first time at the Deburring Expo in Karlsruhe.
Development of the engraflexx LC-U with brush attachment
May 15, 2017
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.
First major customer for electric spindle
May 15, 2016
Since that time a major customer who is a supplier to the automotive industry has purchased and is now using more than 10 engraflexx ESP deburring spindles with high frequency electric motor drives.
Development of further versions of the engraflexx LC tool series
May 15, 2015
Further versions were developed based on the engraflexx LC – for deburring reverse sided edges as well as for forward and reverse edges of any undefined workpiece contours.
Unique workpiece stop system Milling exact radii or chamfers
May 16, 2014
Thanks to the development of this stop system it is possible to mill exactly defined chamfers or radii on undefined edges (e.g. on castings, etc.).
Patent granted for the engraflexx LC
May 15, 2014
A patent was granted for the axially deflectable engraflexx LC tool type after an examination lasting more than two years.
Development of the engraflexx ELC
May 15, 2013
The axially spring-loaded engraflexx ELC deburring spindle was developed for use on robots and customised equipment as a supplement to the laterally deflectable spindle. The ELC version also has a high frequency spindle motor, the rotational speed of which can be controlled.
Deflectable, electrically driven deburring spindle
May 15, 2012
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.
Development of the engraflexx SX deburring spindle
May 16, 2011
The engraflexx SX is a spindle with lateral deflection which can be fitted with any motor. When equipped with the corresponding adapter this spindle can also be used for special applications on CNC machines.
Introduction and patent application of the engraflexx LC deburring tool with lateral deflection.
May 15, 2011
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.
Market launch of the roller embossing tools
May 15, 2010
The roller embossing tools, which are based on scratch marking tools, were developed to meet a specific customer requirement. An application for the corresponding patent protection was filed with the Patent Office at the same time.
Development of the gravostar WSRX-20 tool type
May 15, 2009
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.
Patent granted for the engraflexx EC deburring tool
May 15, 2008
A patent was granted for the engraflexx EC deburring tool just under two years from the application for the patent and market launch.
Relocation to Oberuzwil
July 15, 2007
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.
June 15, 2007
ISO 9001 certification granted in 2007 following the long-term maintenance of quality standards of the tools we manufacture.
A world first – the engraflexx EC
May 15, 2007
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.
Commencement of sales to the deburring tools sector
May 15, 2006
As a result of the great interest shown by visitors to the EMO the pneumatically driven engraflexx AP was modified and launched on the market; this tool was intended primarily for use in robot systems.
May 15, 2005
Our tools were shown for the first time to a large-scale international audience when we took our first stand at the EMO in Hanover. This exhibition was also the occasion of the introduction of the newly developed deburring tool.
First patent granted
May 15, 2001
The patent for the hydraulically driven (i.e. using the coolant) micropercussion tool was granted just under two years after application was filed.
The range was increased by the scratch marking tools
February 18, 2001
The scratch marking tool range was developed following the demand from the market for a simpler version of the marking tools.
Tools supplied to the first major customer
February 18, 2000
Daimler became our first major customer only a few months after the official introduction of the micropercussion tools.
Market launch of the first micropercussion tools
February 16, 2000
The first hydraulically driven micropercussion tools for CNC machines were introduced at the Tool Exhibition in Sinsheim – a world first!
Development and test phase
December 15, 1999
After a lengthy development and test phase, the micro percussion tools for CNC machines project was successfully completed. The sales launch took place in spring 1999.
