Our goal lies in continuous technical development

  • 1933Fabrication of the first thread milling machine and hence the beginning of the GROB machine tool construction
    1939Process development of cold profile rolling of metal parts and building of thread rolling machines
    1952Beginning of the fabrication of special-purpose machine tools, e.g. cutting and centring machine
    1955Engineering and fabrication of dial table and shuttle machines as well as precision finishing machines
    1961Delivery of the 500th GROB special-purpose machine at the Munich plant, a 4-way, 8-station planetary table machine for pressure valve seats (customer: METAL-EXPORT, Poland)
    1968First transfer line from GROB as a 13-way, 10-station machine for the machining of refrigerator compressor housings for Bosch in Nürnberg. First GROB special-purpose machine with NC control for type-dependent, modified (flexible) transfer stroke
    1970First transfer line for the machining of truck front axles completely engineered, built and assembled at the Mindelheim plant
    1977First GROB machining center, for the processing of axle housings for vehicles
    1982Delivery of the first automatic assembly line for car oil pumps
    1983Development and beginning of the BZ series
    1984Development and fabrication of the first gantry - highly dynamic and with accurate positioning
    1996Introduction of a machining center BZ40CS – a highly dynamic and particularly compact machine. To be used as a single machine, in production systems or as a 3-axis CNC module for transfer lines
    1998First GROB machining center with linear motor drives (BZ600L) for high speeds and accelerations in the linear axes
    1999The first universal machine of type BZ510 was developed for the broad market. Premiere for the first dual-spindle machining center BZ520 - a quill machine, suitable for wet and dry machining 
    2000Market launch of the BZ series with the highly productive types BZ530 and BZ540 as dual-spindle quill machines, for automatic loading and unloading of the workpieces. They were particularly suitable for flexible production systems that were increasingly in demand. The BZ1250 and the BZ1600 were added as large T types (pallet size up to 1600 x 1800 mm) 
    2003Delivery of the world's first flexible production system with minimum quantity lubrication for the complete machining of gearbox housings in mass production
    2004The successful market launch of the modular machining centers of the G-series was a milestone in the GROB company history, meeting with high customer acceptance 
    2007The latest GROB innovation is presented at the EMO in Hannover. The G350 - a 5-axis standalone machining center with state-of-the-art technology
    2008The 1000th G-module was manufactured at the GROB factory in Mindelheim on April 30, 2008, only just over three years after the market launch at the end of 2004
    2009In November 2009, the 5-axis standalone machining center G550 - the big sister of the G350 - is introduced to the trade press
    2010World premiere of the "hydraulic-free machining center" at the AMB in Stuttgart. First modular special-purpose machine entirely without hydraulics. Development of a modular cell for the in house machining of machine bases
    2011Presentation of the 5-axis milling-turning machining center G550T at the EMO in Hannover. A 5-axis machining center with an electromechanical pallet changer is also shown. A production system with compact automation, part changer and gantry is also presented as another new development. Development of a flexibly interlinked production system for the in-house production of medium-sized components of the G-modules
    2012Newly developed, flexible production system for our in house production of large components, consisting of four brigde type machining centers with horizontal-vertical machining head in the C-axis and in the Y-slide
    2013After the successfull introduction of the G350 and G550 universal machines in the market in recent years, the G750 with an even bigger working area was presented at the EMO 2013. Further more the linear gantry as a completely new development with extremely high dynamics was presented. The linear motor accelerates the two carriages at a rate of 7,5 m² to a fast-motion speed of 450 m/min.
    2014Market launch of G-Net redevelopment (Industry 4.0 application)
    2015Redevelopment of a thermal spraying system for engine blocks
    Introduction of a new generation of machines in the system and universal machine segment (including optimization of machines and modules)
    Development and introduction of the G800 with 6-axis kinematics, the initial machine of a large-scale machining series
    Development of a modular assembly concept
    Introduction of the new GROB-Net4Industry software technology at the EMO in Milan (networking and digitalization of production processes based on G-Net)
    Market launch of the PSS-R5/10/13 rotary pallet storage system
