1970

Founding of Fässler AG. First product was a Diamond Dressing Unit DSA-02 for dressing of worm-shaped grinding wheels. Universal use of dressing was made possible by using two motors and well as two dressing wheels.

1974

Albert Fässler invents a process to remove heat-treat distortions on gears after the heat treating with an internal-toothed tool. This process was called for a long time simply „Fässlern“ and is referred to today as Gear Honing. Originally the inventor wanted to remove dirt, transport damage and burs from the flanks of the gears. The further value of this process was only discovered later.

1979

Shipment of the first gear honing machine worldwide - the D-250 with NUM controls.

1990

Development of hard broaching of inner profiles with diamond tooling and the introduction of the Hard Broaching Machine using this tooling, the HS-100.

1993

Introduction of a second- generation Gear Honing Machine, the K-400 with driven tooling and work piece axes. This machine is built on top of a Studer Grinding Machine base.

1996

Introduction of a smaller machine based on the K-400 Gear Honing Machine, but having only a driven tooling axis - the K-300- which replaced the previous model D-250-C.

The beginning of a research project at the ETH Zürich was laying the foundation of the study of the honing process, which had previously been lacking in process based values. Many further development steps in the field of tool layout, tool material and well as the most up-to-date drive technology were taken as a basis for future generation machine development as a result of this.

2002

Introduction of a further optimized Gear Honing Machine, the K-400-D, based on a K-400 with direct-driven axes with which large quality improvements could be obtained.

2003

Introduction of a further optimized Gear Honing Machine, the improvement of the HS-100 Hard Broaching Machine, the HS-100-A with a new drive system, which allowed for improved process strategies.
Introduction of the new high-output HMX-400 Gear Honing Machine, with a dual-spindle concept for optimal work piece change-over times. Standard on this machine is that all spindles use direct drive technology.

2004

Market introduction of the HMX-400 Machine.

2006

Introduction of the HMX-400 S as a single-spindle machine. Further development of the HMX, optimization of the honing process via increased functionality for applications.
