SMW Autoblok’s APS 138‑E and APS 138‑I zero-point clamping modules are engineered to provide <0.005-mm repeatability, optimal rigidity and universal interface compatibility across nearly all zero-point systems. 

The APS 138 series enables high-speed part changeover, full automation support and high machining accuracy across turning, milling and grinding operations.

With the APS 138-E for external mounting and APS 138-I for integrated, built-in applications, both modules provide the same mechanical performance characteristics: a three-jaw clamping design, spring-actuated locking and pull-down forces up to 26 kN. Holding force reaches 75 kN using standard ISO 4762-12.9 screws, and modules can be unlocked pneumatically at 6 bar via side or bottom actuation.

The APS system serves as a universal interface between the machine tool, clamping device and workpiece. It requires no traditional fixturing methods and is well suited for pallet automation and modular setup.

All APS modules are Proofline sealed, meaning they are fully protected against coolant, corrosion and swarf. An integrated air purge system for cleaning and locating surfaces is standard, helping maintain chip-free mating surfaces, essential for automation and high-tolerance part handling. Select models support pneumatic stroke control (SC) for real-time monitoring and feedback during robotic load/unload cycles.

The three-jaw system includes three clamping slides, providing higher pull-down forces and eliminating the need for special setups during multidirectional milling operations. The APS 138 series supports both manual and robotic workflows without compromising speed or accuracy.

Whether applied externally or internally, the APS 138 series is well suited for high-speed, automated part changeover without compromising accuracy, uptime or system flexibility.

“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,” says Larry Robbins, president and CEO at SMW Autoblok USA.
