Frequently Asked Questions

1. What is a Shrink Fit Extension? ▼

A Shrink Fit Extension is an attachment used to extend the reach of cutting tools in CNC machining. It uses shrink-fit technology to hold tools firmly and maintain high accuracy, even at longer overhangs. As a precision tools supplier in the USA, PAC Precision Tools provides extensions designed for stable and precise machining.

2. Why are Shrink Fit Extensions used in CNC machining? ▼

They are used when tools need extra reach to access deep cavities, pockets, or hard-to-reach areas. Shrink Fit Extensions offer strong clamping, low runout, and excellent rigidity, helping maintain accuracy even during long-reach machining.

3. Are Shrink Fit Extensions suitable for high-speed machining? ▼

Yes, they are balanced for high-speed operations and provide vibration-free cutting. This helps improve surface finish, reduce chatter, and extend tool life, making them suitable for precision machining and mold-making applications.

4. What tool shank sizes are supported by Shrink Fit Extensions? ▼

They are compatible with standard h6 tolerance tool shanks. PAC Precision Tools USA offers various bore sizes to fit many carbide tools commonly used in CNC machining.

5. How do I install a tool into a Shrink Fit Extension? ▼

Use a shrink-fit heating device to heat the extension, which expands the bore. Insert the tool, allow it to cool, and the shrink-fit mechanism will tightly grip the tool shank, providing exceptional holding force and accuracy.

6. How should I maintain a Shrink Fit Extension? ▼

Clean the bore regularly, remove chips or coolant buildup, and store the extension in a moisture-free environment. Avoid overheating during shrink-fit cycles to maintain precision and prevent material fatigue.
