      Frequently Asked Questions
      Q What is the maximum spindle speed for the HSK-A-HPC High-Speed Power Chuck?
      The HSK-A-HPC High-Speed Power Chuck is balanced to G6.3 and supports a maximum spindle speed of 15,000 rpm, making it suitable for high-speed CNC machining applications.
      Q What is the runout accuracy of the HPC, BT-MLC, and SK-MLC Power Chucks?
      All three series — HPC, BT-MLC, and SK-MLC Power Chucks — achieve a runout accuracy of ≤ 0.01 mm (X3D), ensuring high precision during machining operations.
      Q Is a collet included with the power chuck when purchased?
      No, the collet is not included with the standard power chuck. A wrench is included with each unit, but collets must be ordered separately. Kit versions (e.g., BT-MLC Kit and SK-MLC Kit) include a set of collets in various sizes.
      Q What tool shank diameter tolerance is required when assembling tools to the power chuck?
      When assembling tools, the right diameter tool tolerance must be > h7. A suitable shank diameter is required, and clamping without the proper tools is strictly forbidden to ensure safe and accurate operation.
      Q What spindle interfaces are available for the MLC Power Chuck series?
      The MLC Power Chuck series is available in multiple spindle interface options including BT30, BT40, BT50 for the BT-MLC series, and SK30, SK40, SK50 for the SK-MLC series, as well as HSK63A and HSK100A for the HSK-A-HPC series.
      Q What clamping range is covered by the available power chuck models?
      Depending on the model, the clamping range typically starts from 6 mm and extends up to 42 mm. Common collet sizes include SC16, SC20, SC25, SC32, and SC42, covering a wide range of tool shank diameters for various machining tasks.
