SMW Autoblok has recently launched its latest APS 138-E and APS 138-I zero-point clamping modules, designed for exceptional precision with repeatability of less than 0.005 mm. Built for maximum rigidity and seamless compatibility, the modules integrate effortlessly with almost all existing zero-point systems.
The APS 138 series ensures faster part changeovers, supports full automation, and enhances machining accuracy across turning, milling, and grinding applications.
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 TURBO-assisted 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.
“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,” said Larry Robbins, President and CEO at SMW Autoblok USA.
Engineered for Integration
The APS system serves as a universal interface between the machine tool, clamping device, and workpiece. It requires no traditional fixturing methods and is ideal for pallet automation and modular setup.
All APS modules are Proofline® sealed, 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 3 clamping slides, providing higher pull-down forces and eliminating the need for special setups during multi-directional milling operations. The APS 138 series is fully suitable for automation, supporting both manual and robotic workflows without compromising speed or accuracy.
Key Technical Features:
- < 0.005 mm repeatability across changeovers
- Turbo-enhanced pull-down and spring-locked holding for rigid clamping
- 3 clamping slides for higher pull-down forces and simplified multi-directional milling setups
- Universal fit for most industry-standard zero-point geometries
- Standard integrated air purge system for clean, repeatable interfaces
- Suitable for full automation, including robotic loading/unloading
- Hardened steel construction for long service life in production environments
- 100% modular design for flexible machine tool adaptation
Whether applied externally or internally, the APS 138 series is ideal for high-speed, automated part changeover with no compromise on accuracy, uptime, or system flexibility.
