What is swissMODULAR?
swissMODULAR is a brand launched in 2023 by the Swiss company Triag International AG, focusing on modular workholding solutions in CNC machining. It includes various workholding systems such as rail-based modular vise solutions and fixture towers (also known as tombstones) made from epoxy mineral casting. The core idea behind swissMODULAR is to provide machine shops with a system where the same interface and modular structure can be used across multiple applications, eliminating the need for a custom fixture design for every job.
In practice, swissMODULAR is especially relevant to milling, 5-axis machining, and automated production solutions, where setup time management and repeatability are key competitive factors in the machining industry.
The Background of swissMODULAR and Triag International AG
The history of swissMODULAR dates back to Triag AG, which was founded in 1990 in Cham, Switzerland. Early on, the company developed modular fixturing solutions, such as the microCLAMP and twinCLAMP systems, based on precise mechanical positioning. Later, the product range expanded to include solutions such as powerCLAMP and aptoCLAMP and fixtures made from epoxy mineral casting.
In 2013, the company’s operations were reorganized so that Triag International AG would focus on production and global distribution. The swissMODULAR brand brings together this development work, representing a complete approach to modular fixturing technology on a global scale. The company is located in Hünenberg, Switzerland, which is also where product development and manufacturing take place.
swissMODULAR and Modular Fixturing Technology in Machine Shops
The core idea of modular fixturing technology is to build fixturing systems from standardized components that can be combined as needed. swissMODULAR uses a unified interface onto which various vise modules, stops, and support elements can be mounted. This allows the same basic structure to accommodate different workpiece sizes and shapes without extensive redesign.
In the machine shop, this is especially visible in reduced setup times and improved repeatability. When module positions are determined precisely, for example, using a toothed rail or a vernier-type interface, the fixturing can be disassembled and reassembled with control and accuracy. This reduces the need for manual measurements and minimizes the potential for errors, which is critical in production runs and small recurring batches.
swissMODULAR and 3D Modularity in Machine Tools
swissMODULAR emphasizes so-called 3D modularity, where fixturing is addressed not only on the tabletop level but also vertically and on multiple sides. This is particularly important in horizontal machining centers and pallet systems, where workpieces can be machined from several sides in a single setup.
When fixturing towers and modular vises are designed to utilize the machine's entire working envelope, multiple workpieces can be machined at once on a single pallet. This improves machine utilization and reduces downtime, since the machine can run longer without changing parts. In 5-axis machining, a modular solution also helps reduce tool overhang, improving rigidity and surface finish.
swissMODULAR and Epoxy Mineral Casting in Fixtures
A distinct feature of the swissMODULAR system is the use of epoxy mineral casting for fixture towers. Epoxy mineral is a material that combines mineral fillers and a polymer binder. Its properties include excellent vibration damping and dimensional stability, which are beneficial in precision machining.
For a machine shop, this means the fixture tower is not just a mechanical support, but part of the machining process dynamics. Effective vibration control extends tool life, improves surface quality, and ensures dimensional accuracy. In addition, epoxy mineral structures can be lighter than comparable steel constructions, making handling easier and placing less load on the machine’s pallet system.
swissMODULAR and the Mixed Clamping Approach
The swissMODULAR concept also includes the idea of clamping various jobs simultaneously on the same machine. In a mixed clamping solution, it’s possible to load different workpieces on one pallet, allowing the machine to perform several machining steps in a single run. This is especially useful for shops producing several small batches concurrently.
This approach requires reliable zero point clamping, sufficient tool station capacity, and effective automation. When these basic requirements are met, modular clamping enables flexible production and reduces lead times, without incurring significant setup costs for every new job.
Summary
swissMODULAR is a brand of modular workholding solutions based on technology developed by Triag International AG. It brings together a standardized interface, rail-based vise modules, and epoxy mineral cast fixture towers into a comprehensive system suited for CNC milling, 5-axis machining, and automated production environments.
For machine shops, swissMODULAR means controlled modularity: fewer individual custom fixtures, greater repeatability, and improved machine utilization. Its value is especially clear when production involves changing jobs, multi-part clamping, and the need to minimize downtime.
