HP155130 Manal Quick-Change Series (Aluminum Jaw): Heavy-Duty Precision with Enhanced Grip for Medium-to-Large Workpieces

Traditional steel jaws are the backbone of heavy-duty clamping, but they often fall short when machining medium-to-large workpieces that require both stability and grip—either they’re too heavy for high-speed rotary machining, or their smooth surface risks slippage on delicate aerospace panels or medical components. The HP155130 Manual Quick-Change Series (Aluminum Jaw)（155*130*93mm） is engineered to bridge this gap, combining the strength of heat-treated hardened steel with the traction of aluminum to deliver unmatched precision, versatility, and productivity for demanding applications like aerospace structural machining, medical device production, or heavy machinery component manufacturing.

Designed for Unobstructed Center Access & Heavy-Duty Stability

The HP155130’s 15513093mm footprint provides a wide, stable clamping surface ideal for securing large, irregularly shaped workpieces (e.g., aircraft fuselage panels, wind turbine hubs, or heavy equipment bases) that smaller jaws can’t handle. Its optimized center space eliminates axial interference, making it perfect for bar-feeding operations on lathes or wire EDM on 5-axis mills—critical for shops machining parts with central features (e.g., hydraulic ports, mounting holes) that require full spindle clearance.

Built for Grip & Durability in Demanding Environments

The jaw’s core is constructed from heat-treated hardened steel for maximum strength and wear resistance, while the clamping surface is machined from aluminum—striking the perfect balance between 7.3kg weight (manageable for rotary tables/indexers) and 20kN clamping force (75Nm torque). The aluminum surface provides superior traction for delicate workpieces (e.g., thin-walled aerospace frames, precision medical implants), ensuring zero slippage during high-precision machining. This combination is non-negotiable for aerospace and medical shops, where part accuracy and repeatability directly impact safety and performance.

Manual Quick-Change for Zero Downtime

As part of the manual quick-change series, the HP155130 features tool-free manual operation for rapid jaw swaps. This reduces downtime by up to 50% compared to traditional bolted jaws, making it ideal for job shops or production lines where frequent workpiece changes (e.g., batch machining of large aerospace components) are the norm. No more wasting time tightening bolts or realigning—just turn the knob, load new parts, and re-clamp.

Versatile for Rotary & Multi-Axis Machining

Built for rotary tables, indexers, and multi-axis machining centers, the HP155130 minimizes 5-axis interference to an absolute minimum. Its compact profile (relative to its size) ensures full access to workpiece features like deep cavities, angled surfaces, or thin walls—essential for shops machining complex 5-axis parts (e.g., turbine blades, medical device housings) where every degree of access matters.
