Manufacturers need to avoid abusing their machine tools – but when they do need spare parts, they must receive them as quickly as possible to avoid downtime.
Material challenges
Transportation uses various materials, ranging from aluminum alloys to HRC steels and cast iron. Despite dynamic machining, manufacturers need long periods of reliable productivity, stable precision and reliable tool paths. To tackle these challenges, we provide dedicated spindle solutions with software and hardware support for machining.
Our market-oriented solutions
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 to part production with high material removal rates and equally high surface quality. 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.
Recommended spindles
Step-Tec HPC 190 platform
The HPC 190 spindle platform for roughing and finishing provides power, torque and speed for precision parts including mold and die, aluminum and titanium blisks and blades, in housing diameters as small as 190 mm. 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.
