Hard chuck jaw ASC-150x210A-100

Overview
Pneumatic self-centering 5-axis jaws designed for automated clamping in CNC machining centers. Quick installation, standard air interface, repeatability ±0.015 mm, spring safety mechanism maintains clamping on air loss, alloy steel body and hardened jaws, and reversible quick-change jaws for high flexibility.

Advantages

• One-day installation to increase machine utilization and ensure consistent delivery quality.
• One-touch changeover — button/signal activated; clamps or releases in ≈1.5 s; no wrench required, minimal downtime.
• Guaranteed precision — repeatability ±0.015 mm and stable clamping force ensure uniform part quality and fewer reworks.
• Plug-and-play automation — standard pneumatic interface; supports multiple jaws on a single CNC and easy integration with robots for rapid scaling.
• Fail-safe clamping — spring mechanism keeps the part secured if air supply fails, protecting personnel and equipment.
• Durable construction — alloy steel body and hardened jaws preserve original accuracy under heavy cycles, reducing maintenance costs.
• Flexible workholding — reversible, quick-change jaws adapt quickly to varied parts and allow future expansions.
