Much effort has to be done before a product within the regulated Medtech industry gets its permission. Once achieved, the machining process itself must be 100% reliable to ensure the quality of the products. Because of their criticality, the parts requirements are very high, but depending on the place of usage.
The materials within the Medtech industry vary from tough nickelbased alloys (e.g. bone plates), over cobalt chrome, to Inox (hip implant). Tool-costs influence the process definition, the part integrity must be aligned and furthermore the contamination by process are challenges that have to be considered. Our spindle solutions provide the possibility to monitor the process, thus maintaining the compliance and improving the process with regards to the tool usage. Additionally the spindles can be used both for milling and grinding. This enables you to machine a broad bandwith of different materials and parts.
Our market-oriented solutions
Step-Tec HVC 120 platform
The HVC 120 Spindle platform offers a minimal diameter of 120mm and can accomodate higher diameters. As an HVC platform it provides highest speed with fair power and torque to the achieved precision and surface quality in the Medtech industry. Parts range from bone plates to knee implants. The HVC 120 provides the Twin Air Sealing system, ensuring process cleanliness as well as extreme shaft roundness enabling highest surface qualities.
The HVC 120 Preciprod spindle is ideal for achieving the highest surface requirements in hard materials using the smallest tools, with a maximum speed of 60,000 rpm and 2.7 Nm (S1) of torque.
Step-Tec HVC 140 platform
The HVC 140 Spindle platform offers a minimal diameter of 140 mm and can accomodate higher diameters. As an HVC platform it provides highest speed with fair power and torque to achieve precision and surface quality for parts within the Medtech industry. Typical use cases include different kind of implants as well as parts of surgical instruments. The HVC 140 offers many advantages like the possibility of highest availability through our Spindle Exchange Program (SEP) or the possibility of achieving very precise finishes when milling and grinding through our stiff bearing arrangement backed with P2-quality bearings.
The HVC 140 spindle can mill and grind, and 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 offers a minimal diameter of 150mm and can accomodate higher diameters. This platform combines the advantages of a HVC platform, first of all the high speed and the advantages of the HPC platform, the power and torque for extended roughing. Either for toolmaking or part production, the HVC/HPC 150 platform offers a wide range of advantages. In-house manufactured extrem round shafts for surface quality, Cool-Core technology and Opticool-System for polar temperature stability and thus enabling realiability and optional an AE-sensor for advanced grinding.
Step-Tec HPC 190 platform
The HPC 190 Spindle platform offers a minimal diameter of 190mm and can accomodate higher diameters. As an HPC platform it provides the necessary power, torque and speed for the roughing and finishing of precision parts within the highly quality-sensitive Medtech industry. Typical use cases are implants or parts of surgical instruments. With the HPC 190 platform you get various tools to monitor and improve the production process, maintaining compliance, as well as the possibility to mill, grind and turn within one clamping through our optional spindle shaft interlock and AE sensor.
The HPC 190 One Touch spindle can mill, grind and turn, finish and rough, 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.
