Frequently Asked Questions (FAQ)

Q1: What is the difference between an HSK hydraulic chuck and a standard HSK tool holder?
A: The HSK hydraulic chuck uses a hydraulic chamber to clamp the cutting tool with high accuracy, providing better runout and vibration damping than mechanical or collet-based holders.

Q2: Can I use the HSK hydraulic collet chuck for high speed machining?
A: Yes, our holders are dynamically balanced to G2.5 and suitable for speeds up to 25,000 RPM, making them perfect for high speed machining.

Q3: What types of tools can I clamp?
A: They are ideal for solid carbide drills, reamers, end mills, and finishing tools where precision is critical.

Q4: Are customized sizes or clamping ranges available?
A: Yes, as a professional precision tool holder manufacturer, we offer customized solutions according to your specific CNC machine and application.
