Need help?

Do you have a question about the erowa PowerChuck P without base plate and is the answer not in the manual?

The EROWA PowerChuck P is a sophisticated workholding system designed for precision manufacturing, offering robust performance and ease of use across various applications. This document outlines its key features, technical specifications, usage, and maintenance requirements.

Function Description

The PowerChuck P serves as a versatile clamping system, enabling precise and repeatable positioning of workpieces and tooling. It is designed to integrate seamlessly into manufacturing processes, ensuring high accuracy and efficiency. The system operates pneumatically, providing reliable clamping force for various machining operations. Its modular design allows for flexibility in application, from simple workholding to complex automated setups. The chuck is available in two main configurations: with and without a ground plate, catering to different mounting requirements.

Important Technical Specifications

The PowerChuck P boasts impressive technical specifications that underscore its precision and reliability:

Repeatability: 0.002 mm, ensuring extremely accurate re-positioning of workpieces.
Indexing of the Pallet: 4 x 90°, providing precise angular positioning.
Clamping Power: 10,000 N (Tol. -10%), indicating a strong and secure grip on workpieces.
Air Pressure: The system operates with a compressed air pressure of 6 bar for clamping (P2) and 3 bar for opening (P3).
Operating Temperature: +5° to +70°C, allowing operation in a wide range of industrial environments.
Weight: 3.6 kg, making it a manageable component for integration.
Dimensions: The chuck has a diameter of Ø 149.8 mm and a height of approximately 46.5 mm. It features various mounting holes, including 2x Ø 10 mm and 6x M10, for secure attachment to machine tables or fixtures.
Viton Seal: The system incorporates Viton seals (e.g., ER-005070, Ø 18.5/12 x 9 mm) for enhanced durability and resistance to various fluids and temperatures.
Reference Marks: The chuck includes reference marks (e.g., ER-046221 reference bolt set) for precise alignment and positioning.
Quality of Compressed Air: It is recommended to feed the air supply unit with oil and water separator, ensuring clean air for optimal performance and longevity.

Usage Features

The PowerChuck P is designed for user-friendliness and adaptability in various manufacturing scenarios:

Mounting: The chuck can be mounted directly onto a machine table or integrated into a larger workholding system. For precise alignment, reference pins (e.g., Ø 10h8x20) are used. The mounting surface must be ground to N5 for optimal flatness and accuracy.
Clamping and Unclamping: The system uses pneumatic pressure for clamping (P2) and unclamping (P3). The P2 (open/close) and P3 (cleaning/monitoring) connections are clearly marked.
Flushing Function: An active flushing function through the chuck is available, which helps to keep the system clean and free from debris, especially when using Viton seals and sealing ring centering.
Alignment: The alignment range is limited by the position of the pins Ø10 (17). For optimal precision, the alignment pallet (e.g., ER-116632 for Ø 148 Inox) should be used.
Monitoring: The system can be monitored for pressure and cleanliness, ensuring consistent performance.
Safety Instructions: The manual emphasizes strict adherence to safety guidelines, including wearing personal protective equipment (PPE) such as safety glasses, protective shoes, and hearing protection, especially when working with compressed air. It also warns against unauthorized modifications and improper use, which could lead to severe injury or damage.

Maintenance Features

Regular maintenance is crucial for ensuring the longevity and optimal performance of the PowerChuck P:

Weekly Maintenance:
- Grease Balls: Grease the balls weekly to ensure smooth operation.
- Centering Prisms and Z-Auxiliary Support: Clean and protect the centering prisms (3) and Z-auxiliary support (4) against damage through knocks.
- Viton-Dichtung ER-005070 (12) and Chip Guard ER-014687 (2): Check these components for hardness or brittleness and replace if necessary.
Monthly Maintenance:
- Taper Cleaning: Clean the taper monthly to prevent accumulation of debris.
Regular Checks:
- Housing, Balls, Centering Prisms, Pneumatic Connections: Visually inspect these components for damage or wear.
- Cleaning: Clean the chuck after use and protect it against corrosion.
Overhaul: EROWA recommends an overhaul of the PowerChuck P after 200,000 clamping cycles or every 3 years, whichever comes first. A comprehensive manual for the overhaul is available in the Repairkit.
Spare Parts: A range of spare parts is available, including Viton seals (ER-005070), chip guards (ER-014687), sealing rings (ER-115722), and repair kits (ER-115749). These parts are essential for routine maintenance and repairs.
Troubleshooting: The manual provides a detailed troubleshooting guide for common issues such as clamping failures, pressure problems, and repeatability errors, offering solutions and recommended actions.
Documentation: All maintenance and repair activities should be documented to ensure proper tracking and compliance.

The EROWA PowerChuck P is a reliable and high-precision workholding solution designed to meet the demanding requirements of modern manufacturing, supported by comprehensive documentation and available spare parts for long-term operational efficiency.
