Our GOAL is the continuous
further development

1933

Manufacture of the first thread milling machine and thus the beginning of GROB machine tool building.

1939

Development of process for cold profile rolling of metal parts and construction of thread rolling machines. At this point in time, the company had approximately 100 employees.

1952

Start of manufacture of special tool machines.

1955

Design and manufacture of rotary table machines, transfer table machines and precision lathes.

1961

In the Munich plant the 500th GROB special machine was delivered, a 4-way, 8-station planet table machine for pressure valve seats (customer: METAL-EXPORT, Poland).

1968

First transfer line by GROB in the form of a 13-way, 10-station machine for refrigerator compressor housings and first NC control on a GROB special machine for type-dependent, flexible transfer.

1970

First transfer line for the machining of truck front axles that was completely designed, built and assembled in the Mindelheim plant.

1977

First GROB Machining Center; the machine was built to machine vehicle axle bridges.

1982

Delivery of the first automatic assembly line for passenger vehicle oil pumps.

1983

Beginning of the Machining Center (BZ) series.

1984

Development and manufacture of the first robots as portal robot versions, highly dynamic and precisely positioning.

1996

The BZ 40 CS machining center – a highly dynamic version - was designed in a particularly compact way. It was suitable as a stand-alone, as a component in manufacturing systems and as a 3-axis CNC module for conveyor lines. This new development met the need for flexible, fast, high-performance machines in industrial manufacturing.

1998

First GROB machining center with linear motor drives (BZ 600 L) for high speeds and accelerations on the linear axes.

1999

The modular series of the GROB machining centers was expanded by the BZ 510 model in its function as a universal machine for those needing only one machine. The first 2-spindle machining center was created – BZ 520, a quill spindle machine suitable for wet and dry machining.

2000

Once more the series of the machining centers was expanded. The highly productive models BZ 530 and BZ 540, as 2-spindle quill spindle machines, were added for the automatic loading and unloading of the workpieces. They are therefore highly suitable for the flexible manufacturing systems that are increasingly in demand. As large T models, the BZ 1250 and the BZ 1600 were added (palette size up to 1,600 x 1,800 mm).

2003

Delivery of the first flexible manufacturing system worldwide with MQL ( Minimum Quantity Lubrication) for the complete machining of high volume transmission cases.

2004

The market introduction of the modular machining centers of the G series was a milestone in GROB’s corporate history and received high customer acceptance.

2007

The latest innovation from GROB is being presented at the EMO in Hanover (Germany). The G350 - a 5-axes Universal Machining Center with state-of-the-art technology

2008

Grob Werke in Mindelheim finished the 1000th G module on April 30, 2008, only a little over 3 years after its introduction to the markets at the end of 2004.
