Overview

This document provides detailed technical information on various types of magnetic chucks, including permanent magnetic chucks, permanent electromagnetic chucks, and their controllers. It covers product specifications, features, applications, and operational guidelines for models used primarily in machining and grinding operations.

1. Product Types and Applications

• Permanent Magnetic Chucks: Used for holding workpieces securely without continuous power supply. Suitable for high-precision machining.
• Permanent Electromagnetic Chucks: Require electrical control for magnetization and demagnetization, offering adjustable holding power.
• Chuck Controllers (Chuck Masters): Devices that supply controlled electrical power to electromagnetic chucks, enabling momentary magnetization and demagnetization, and low magnetic force control for precise operations.
• Magnetic Blocks and Tool Holders: Accessories for measuring and holding tools magnetically.

2. Model EPZ-U Rotary Type Permanent Electromagnetic Chucks

Features:

• Scaled rotary shaft for easy angle setting.
• Electricity applied only momentarily during mounting/dismounting to minimize heat generation.
• Holding power maintained without continuous power, enhancing safety during power failures.
• Recommended to limit on/off switching to once every several minutes to prevent overheating.

Specifications (Selected Models):

3. Chuck Controllers (EPS Series)

Purpose: Convert AC power to DC and provide momentary exciting current to permanent electromagnetic chucks. They also feature automatic demagnetization to reduce residual magnetism.

Features:

• Microcomputer control for effective automatic demagnetization.
• Adjustable holding power.
• Designed for use with models EPT, EPT-H, EPTW, and EPZ-U.

Models and Specifications:

4. Low Magnetic Force Control Chuck Masters (EPH-LW Series)

Purpose: Enable low magnetic force control for permanent electromagnetic chucks, facilitating straightening grinding operations and smooth positioning of workpieces.

Features:

• Continuous power supply in low output region allows fine adjustment of holding power.
• Improves machining accuracy by enabling straightening grinding similar to electromagnetic chucks.
• Low magnetic force control requires continuous electricity, which may cause slight heat-related accuracy changes over long use.
• Compatible with permanent electromagnetic chuck Model EPT-LW.

Models and Specifications:

5. Important Operational Guidelines and Recommendations

• Use KANETEC chuck controllers for optimal performance with KANETEC chucks.
• Limit on/off switching of permanent electromagnetic chucks to once every several minutes to avoid overheating and damage.
• Momentary application of electricity during mounting/dismounting minimizes heat generation and maintains machining precision.
• Holding power is maintained even during power failure or cable breakage, enhancing safety.
• Low magnetic force control requires continuous power and may cause slight heat-related accuracy changes over extended use.

6. Summary

The document details a range of magnetic chuck products and their controllers designed for precision machining and grinding. Permanent electromagnetic chucks with rotary capability offer energy-efficient operation with minimal heat generation. Chuck controllers provide controlled power supply and demagnetization functions, while low magnetic force control models enable fine adjustment of holding power for specialized operations. Proper use and adherence to operational limits are critical to maintain performance and safety.
