Our strength

Compact design

Achieve the highest precision with an extremely compact, stable spindle system that offers proven results for machine builders. Select bearing systems and preload types deliver minimal axial displacement of the spindle shaft in a slim housing.

Temperature stability

For precise machining and longer machine life, stabilize temperature behavior faster with Step-Tec than with other spindles. Opticool and COOL-Core cooling compensate for the temperature fluctuations that result from speed changes, yielding better part results.

Long life

Step-Tec motor spindles set the standards for spindle life, precision and economy. Our constant innovation, in-house production of key spindle elements, specialized technology and quality assurance have developed Step-Tec into a proven performance line.

Industries

Do you face the challenges of quality, integrity and accuracy while optimizing costs and increasing flexibility and traceability in uncertain market conditions? In fast-growing market segments, we enable a future in which even the most complex and demanding industries profit from intelligent, high-performance, resource efficient and fully predictive motor-spindle solutions.

Spindle platforms

Platforms are spindles of the same diameter with as many common parts as possible and broad bandwidth of performance. So the platforms are easy to interchange as no new housing is required. Within one platform there are plenty of specific spindle performances.

History

Foundation of STEP TECH AG

Founded in a garage, STEP TECH (Spindle Tools Engineering Periphery Technology) was created to develop the world's best high-performance milling spindle.

Development of the STEP TECH HVC 140

STEP TECH develops and manufactures its first 42,000 rpm high-speed motor spindle for Mikron AG. With several thousand units manufactured, this successful product is still part of today's portfolio. STEP TECH became Step-Tec.

First spindle delivered to Boeing

Boeing utilizes Step-Tec’s high-speed spindles for manufacturing integral aluminum parts with high buy-to-fly (BTF) ratios.

First-generation Spindle Diagnostic Module

By collecting and storing critical data such as operating time or bearing temperature, Step-Tec’s Spindle Diagnostic Module enhances CNC machine performance.

Second-generation Spindle Diagnostic Module

Step-Tec further digitalizes machine tools by introducing a Profibus interface for CNC systems, able to collect extensive diagnostic data.

HPC 190 platform concept

The HPC 190 served to replace multiple individual spindle designs, unifying them into a single, versatile platform. This innovative concept offers a portfolio of platforms to be further customized.

Step-Tec HVC 140 – new generation

Featuring the innovative Opticool concept, this new-generation spindle significantly reduces thermal impact on machine tool components, boosting precision and performance.

Patented electromagnetic shaft lock

Our patented electromagnetic shaft lock removed the necessity for a hydraulic unit as a peripheral device, greatly simplifying spindle integration and reducing its costs.

Short HSK-T63 Spindle

This engineering masterpiece integrated a shaft lock into a super compact spindle design, supporting multi-process operations on machine tools with swiveling head kinematics.

Third-generation Spindle Diagnostic Module

Exhibiting a Profinet interface to the CNC as well as a digital interface for 3-axis vibration sensing and tool position monitoring, this module allows for in-process optimization and predictive maintenance.
