High-Performance Manual Chuck with Vertical/Horizontal Mounting for Macro-Style Systems

The PA-21032V-TR is a precision manual chuck designed for Macro-style automation systems. It features two precision-ground faces, allowing for flexible mounting either vertically or horizontally on machine tables or fixtures. This versatility makes it an ideal choice for machining centers, EDM machines, and custom workholding setups where orientation flexibility is required.

Constructed from high-grade Japanese stainless steel and hardened to 57–60 HRC, this chuck delivers exceptional wear resistance, corrosion protection, and long-term accuracy. The precision-ground reference surfaces ensure consistent seating of Macro-style components, while the robust clamping mechanism delivers a locking force of 6000 N—sufficient for a wide range of machining applications.

The chuck features fixed index positions at 4×90°, allowing for quick orientation changes without losing reference. An integrated flushing duct enables coolant or EDM dielectric fluid to be directed through the system, improving chip evacuation and machining performance.

Designed for easy installation on machine tables with its dual-mounting capability, the PA-21032V-TR is ready to integrate into new or existing setups. It is compatible with Macro-style manual spigots (drawbars) such as PA-21003V-TR, and requires a simple 6 Nm tightening torque for secure locking.

Key Benefits:

• Flexible Mounting: Two precision-ground faces enable vertical or horizontal installation, adapting to various machine configurations.
• High Clamping Force: 6000 N locking force ensures secure holding for heavy workpieces and aggressive machining.
• Precision Ground References: Guarantees repeatable positioning and interchangeability with Macro-style components.
• Indexing Capability: 4×90° fixed positions allow rapid workpiece or electrode orientation.
• Flushing Ready: Integrated duct supports coolant or EDM fluid flow for enhanced process efficiency.
• Superior Durability: Japanese stainless steel with 57–60 HRC hardness withstands daily shop floor use.
• Cost-Effective: Delivers reliable performance at a competitive price compared to branded alternatives.

Typical Applications:

• Manual workholding on machining centers with vertical or horizontal spindles
• EDM applications requiring flexible chuck orientation
• Fixture mounting for quick changeover in mold making
• Semi-automated cells requiring consistent reference positioning
• Custom workholding setups with space or orientation constraints

Compatibility: The PA-21032V-TR is designed for use with Macro-style pallets, centering plates, reference elements, and manual spigots. It is fully compatible with systems utilizing the industry-standard Macro interface.

Note: For optimal performance, use with recommended manual spigot (PA-21003V-TR) and tighten to 6 Nm. Ensure mounting surfaces are clean before installation. When mounting vertically, verify that the chuck is securely fastened to the machine table.
