Automotive

Automotive machining requires the highest-possible efficiency to meet the pressures of internal market downturns and external crises.

Automotive manufacturers must make incremental changes in components and manufacturing processes to improve the mature technologies of combustion-engine technologies. At the same time, they must machine new materials with equal efficiency and reliability to build tomorrow's vehicles, which are lightweight, low emission and quiet.

Our market-oriented solutions

Step-Tec HVC 140 platform

The HVC 140 spindle platform achieves high precision and surface quality on small automotive parts such as light molds, with good power and torque in housing diameters as small as 140 mm. Achieve very precise finishes when milling and grinding with a stiff bearing design backed with P2-quality bearings. This platform offers the highest-possible availability through our Spindle Exchange Program (SEP).


The HVC 140 spindle is perfectly suited to finishing parts in a single clamping, with a maximum speed of 42,000 rpm and 8.8 Nm (S6 40%) of torque.

Step-Tec HPC 150 platform

The HVC/HPC 150 spindle platform for extended roughing combines the high speed of the HVC platform with greater power and torque, in housing diameters as small as 150 mm. Its advantages apply equally to part production, including gears, and to achieving the highest surface quality on tire molds. We manufacture the extremely round shafts in house to provide excellent surface finishes, while COOL-Core technology and the Opticool System provide reliability through polar temperature stability. For advanced grinding, add an optional AE sensor.

The HVC/HPC 150 Tool Maker spindle finishes parts with high precision and quality, with a maximum speed of 36,000 rpm with 33 kW (S6 40%) of power.

Step-Tec HPC 190 platform

The HPC 190 spindle platform for roughing and finishing of precision parts and for part production provides power, torque and speed for a cost-sensitive industry, in housing diameters as small as 190 mm. It excels at medium-to-large motor parts and even crankshaft molds. We manufacture the extremely round shafts in house to provide excellent surface finishes, while COOL-Core technology and the Opticool System provide reliability through polar temperature stability. This platform offers the highest-possible availability through our Spindle Exchange Program (SEP). To mill, grind and turn in a single clamping, add an optional spindle shaft interlock and AE sensor.

The HPC190 One Touch spindle can mill, grind and turn, rough and finish, all in a single clamping, with a maximum speed of 20,000 rpm, 36 kW (S6 40%) of power and 120 Nm (S6 40%) of torque.

Step-Tec HPC 240 platform

The HPC 240 spindle platform for roughing and finishing of precision parts provides power, torque and speed for a cost-sensitive industry, in housing diameters as small as 240 mm. Its wide range provides an optimal solution for molds and part production, with short spindles for tilting heads to boost efficiency. Twin Air Sealing eases machining of new mud-sensitive materials, including composites, while the spindle shaft interlock enables mill-turn processes.
