Timeline

2020
2020

Expansion of the milling cutter range

Various new and further developments were made in the area of stop milling cutters and special milling pins.

2019
2019

Development of the gravostar HRY-20 PP

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.

2018
2018

Development of the gravostar WSXP

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.

2017
2017

Development of the engraflexx LCU with brush attachment

Engraflexx LC-U mit Bürstaufsatz

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.

2016
2016

First major customer for electric spindle

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.

2015
2015

Development of further versions of the engraflexx LC tool series

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.

2014
2014

Unique workpiece stop system: Milling exact radii or chamfers

WA Detail

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.).

2014

Patent granted for the engraflexx LC

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

2013
2013

Development of the engraflexx ELC

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.

2012
2012

Deflectable, electrically driven deburring spindle

Auslenkbare, elektrisch angetriebene Entgratspindel

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.

2011
2011

Development of the engraflexx SX deburring spindle

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.

2011

Introduction and patent application of the engraflexx LC deburring tool with lateral deflection

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.

2010
2010

Market launch of the roller embossing tools

RB Prospekt

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.

2009
2009

Development of the gravostar WSRX-20 tool type

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.

2008
2008

Patent granted for the engraflexx EC deburring tool

A patent was granted for the engraflexx EC deburring tool just under two years from the application for the patent and market launch.

2007
2007

Move to Oberuzwil and QA certification

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.

2007

ISO 9001

logo sqs

ISO 9001 certification granted in 2007 following the long-term maintenance of quality standards of the tools we manufacture.

2007

World first – engraflexx EC

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.

2006
2006

Sales launch of the deburring tools division

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.

2001
2001

First patent granted

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

2001

Range was increased with the scratch marking tools

The scratch marking tool range was developed following the demand from the market for a simpler version of the marking tools.

2000
2000

Market launch of the first needle embossing tools

Meilenstein Gravostar

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.

1999
1999

Development and test phase

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.
