SMW Autoblok Clamping Modules Include Automation-Ready Features!

SMW Autoblok has introduced the APS 138-E and APS 138-I zero-point clamping modules, designed to deliver exceptional repeatability, rigidity, and automation readiness across a range of machining applications. Engineered with <0.005 mm repeatability and universal interface compatibility, the APS 138 series supports high-speed part changeovers, full automation integration, and superior machining accuracy for turning, milling, and grinding operations.

The APS 138 series has been developed with versatility at its core. The APS 138-E module is designed for external mounting applications, while the APS 138-I is optimized for built-in integration. Both versions offer identical mechanical performance, featuring a robust three-jaw clamping system, spring-actuated locking, and pull-down forces of up to 26 kN. For even greater holding strength, the modules can reach 75 kN when used with standard ISO 4762-12.9 screws. Unlocking is achieved pneumatically at 6 bar through either side or bottom actuation, offering shops maximum flexibility in system design and operation.

A key advantage of the APS platform is its role as a universal interface between the machine tool, clamping device, and workpiece. By eliminating the need for traditional fixturing methods, the system enables quicker setups, greater precision, and seamless integration with pallet automation systems. This makes it particularly valuable for facilities investing in modular setups and automated workflows where uptime and consistency are critical.

All APS modules are built with SMW Autoblok’s Proofline sealing technology, which provides complete protection against coolant, swarf, and corrosion. This ensures durability and reliability even under demanding conditions. The modules are also equipped with an integrated air purge system that continuously cleans and locates surfaces, maintaining chip-free mating areas essential for high-tolerance part handling and automated loading/unloading cycles.

For applications requiring greater process monitoring, select APS 138 models support pneumatic stroke control (SC), which enables real-time feedback during robotic load and unload operations. This feature enhances reliability in automated environments by ensuring clamping accuracy is maintained throughout the production cycle.

The APS series’ three-jaw design provides superior pull-down forces, reducing the need for special setups during complex multidirectional milling operations. By supporting both manual and robotic workflows, the APS 138 modules give manufacturers the flexibility to scale operations without sacrificing speed or precision.

According to Larry Robbins, president and CEO of SMW Autoblok USA, the APS 138 platform has been engineered as a seamless, high-performance replacement for other zero-point systems in the market. “This platform is designed as a direct-fit alternative to other zero-point systems on the market. Shops don’t have to reconfigure their workholding systems to gain a boost in precision and speed,” Robbins explained.

By combining advanced clamping technology with automation-ready features, the APS 138 series reflects SMW Autoblok’s commitment to providing manufacturers with solutions that align with the demands of modern production. As machining operations increasingly adopt automation and digital manufacturing practices, these zero-point clamping modules enable shops to reduce setup times, improve accuracy, and maximize machine utilization.

With its combination of precision engineering, robust performance, and compatibility with automated workflows, the APS 138 series is well positioned to become a cornerstone in high-productivity manufacturing environments.
