IMTS 2018 Highlights



Long known as our front runner PRECI-FLEX is the most innovative tooling system on the market with a single base holder and multiple tooling adapters that utilize the ER collet pocket. It offers a fast, accurate and cost-effective solution for lathe tooling changeovers.

The short, compact design ensures maximum torque transmission and rigidity, resulting in increased machining accuracy and improved productivity. Additionally, PRECI-FLEX's conical and flat-face planar interface allows the use of either an adapter or a standard ER collet, and enables collets, end-mill holders, expanding collet chucks and shrink-fit tooling to be mounted on a single base holder.

Available in a range of sizes, PRECI-FLEX provides unsurpassed repeatability, with every tool holder offering repeatability within five microns. The system also virtually eliminates machine downtime and allows tooling adapters to be interchanged between fixed and rotary base holders for fast, economical machining.

We manufacturer the industry's best rotary tool holders, also known as live tool holders or driven tool holders. What sets us apart is state of the art technology, solid construction and pin point accuracy. Our axial and radial live tool holders are made specifically for your CNC turning center or turn mill center to provide the best production performance in the industry. ​

  • Tool holders tailored to the envelope dimensions of a specific machine.

  • Compact single body construction

  • Utilization of tapered roller bearings

  • Bearing pockets machined on boring mills to gauge quality

  • Optimized spindle bearing surfaces

  • Specially engineered and individually adjusted Gleason bearings for quiet torque transmission

  • Patented seals, developed by us for minimum heat generation

  • All wear parts hardened and ground

  • Our products are inspected on highly accurate Zeiss measuring machines with the results documented and placed with tool holder

  • Each tool holder has a dedicated test program with temperature and noise conditions measured and documented.

Standard planetary gearboxes are available in PE (planetary eco) and PP (planetary precision) styles for applications that require low backlash, high efficiency, shock resistance and a high-torque-to-weight ratio. With a modular design that combines ground gears and precision gear components, these gearboxes ensure performance efficiency and maximum uptime. They also use less energy and easily mount to a variety of motors through a flexible flange system.

The present range of planetary gearboxes comprises five sizes, with each size offered as a single, dual or triple stage design. Each gearbox variant is also available as a precision design with reduced backlash. The wide assortment of sizes and designs allows users to achieve overall transmission ratios from i = 3:1 to i = 512:1 in a variety of applications.

Servo planetary gearboxes in PT-style are also available for easy installation of all common servo motors with all sizes of the gearboxes. PT-style gearboxes feature a unique design by which all ring gears, planet gears and sun pinions are case hardened and ground to guarantees high stiffness, reliable transmission and allow precise positioning tasks.


Customized solutions for every application at maximum precision. For over 20 years, EXSYS has been known for providing advanced technology, reliability, and a dedication to precision. Our precision gears are manufactured using the highest quality Gleason machines as well as the knowledge of nearly 90 years of manufacturing expertise.

EXSYS/EPPINGER Gear Technology at a Glance:

  • Custom made spiral, hypoid and zerol gears as well as the components for cycloidal and planetary gears.

  • More than 800 gear designs.

  • Maximum crown gear diameter is 330mm smallest module is 0.4mm.

We have ventured in all fields of industrial application, from bevel gears for the automotive sector, robot technology, powered tool holders, handling systems as well as development and designs for the aviation and space industries.
