Engineering

Your partner for engineering and integration

Our Spindles have outstanding characteristics but what good

are they if they don’t correspond to the required interface?

That’s why Step-Tec engineers collaborate with you to

develop the solutions adapted to your needs.

Using the latest failure mode and effects analysis (FMEA)

software applications as well as thermal simulation and

vibration analyses, we come to the table ready to support you.

Our standard risk assessment includes keeping your costs

under control. Before we pursue a customized solution, we

first analyze whether one of our standard solutions—from

our range of more than 100 Spindles—fits to your needs.

We support you to integrate the Step-Tec Spindle to your specific machine setup.

Our focus:• Best fit between the Spindle and the machine’s interface

• Minimum thermal influence of the Spindle to the machine

• Best Spindle performance as a result of intense

pre-analysis of thermal behavior, dynamic behavior

(vibrations, resonances) and defined rigidity within

the machine interface

Technology

A step ahead thanks to pioneering technologies

Continuously shrinking tolerances and increasing demand

on performance call for solutions adapted for thermal

stability and to the Spindle cooling systems. Our engineers

have accepted that challenge and, today, we offer

innovative, unique solutions: OptiCool and CoolCore.

Step-Tec’s OptiCool Spindle series ensures not only that

the Spindle remains thermally stable, but that natural

heat transfer to the Spindle support (e.g., Z-Axis) is limited

to the lowest amount possible, in order to preserve the

machine’s geometry.

Where conventional stator cooling reaches its limits,

Step-Tec’s CoolCore Spindle goes beyond the ordinary to

lower the temperature and minimize temperature fluctu-

ations in the rotating shaft.

OptiCool CoolCore

Stator cooling circuit

Stator and rotor cooling circuit

Heat barrier

Frontal cooling

Highest precision due to optimized thermal balance of the entire machining head

Satisfies the toughest requirements in terms of surface finish, repeatability and reliability

Ultra high-precision ceramic hybrid bearings

Best polar thermal balance around the surface contacting the machine support

Additional advantages of CoolCore+ Cooled shaft reduces the natural thermal shaft growth by

half+ Greatest thermostability and highest precision due to

lower temperature fluctuations down to the tool tip + Significant reduction of thermal recovery time resulting

in a productivity gain

Faster production cycles, best surface qualities, highest possible repeatability. Step-Tec’s unique OptiCool and CoolCore cooling systems soak up heat from the most critical sections of the Spindle andtakes it where it belongs: to the chiller.

Result: lowest possible polar thermal balance around the contacting surface to the machine support

• Highest precision due to optimized thermal balance of

the entire machining head

• High-efficiency motors with reduced thermal exposure

• Separate cooling of motor and all bearings


Support and Services

Ambitious clients become happy customersWith a Swiss Spindle manufacturing legacy going back to 1995, our aim remains to be the technology and innovation leader for future generations. But it is not enough to produce the best Spindles; our commitment extends throughout the life cycle of the Spindle.
