Frequently Asked Questions
1. What are ER nuts used for?
— ER nuts secure the collet within the tool holder. They ensure even clamping pressure, minimizing runout and preventing tool slippage during machining.
2. What types of ER nuts are available?
— PAC offers standard, mini, and bearing-style ER nuts. Mini nuts fit tight spaces, while bearing nuts reduce torque resistance for high-precision clamping.
3. Are ER wrenches size-specific?
— Yes, each ER nut size (e.g., ER16, ER32) requires a matching wrench. Using the wrong wrench can cause poor grip or damage to the nut.
4. Is torque-controlled tightening necessary with ER wrenches?
— For high-precision work, a torque wrench with ER-specific adapters is recommended to avoid over-tightening and to maintain consistent clamping performance.
5. What holder types are supported by PAC tool locking devices?
— PAC offers tool locking stations for CAT, BT, HSK, and other taper holders, available in both horizontal and vertical mounting styles.
6. Why is a tool locking device important in a workshop?
— A locking device ensures safe, stable, and accurate torque application, especially for heavy-duty or high-precision tool setups.
