The HKA.000.CT000.RFR MICKROS spindle chuck is an essential component for securing cutting tools, designed to deliver high performance and precision in high-speed machining applications. This spindle chuck is engineered to accommodate tools made from high-speed steel (HSS) and carbide (HM), making it versatile and suitable for various industrial applications.

One of the standout features of this spindle chuck is its thermal shrink fit system, which allows for optimal coupling between the spindle chuck and the tool. This ensures stability during machining, even at high speeds of around 25,000 revolutions per minute. The precision of the spindle chuck is further enhanced by a run-out of only 3 microns, which ensures accurate machining and minimizes the risk of undesirable vibrations.

The spindle chuck is supplied with an axial setting screw, except for specific spindle chucks intended for tools with diameters of 3 mm, 4 mm, and 5 mm, where the use of a screw is unnecessary. The spindle chuck shank is available in HSK40, HSK50, and HSK63 variants. It can also be customized in terms of length and tool attachment size, allowing for adaptation to specific machining requirements.

In terms of design, this spindle chuck conforms to the DIN 69882-8 standard, which attests to its quality and reliability. The thermal shrink fit spindle chuck supports speeds up to 25,000 revolutions per minute and features a run-out tolerance of 3 microns, ensuring precise tool coupling. The shank has a tolerance of h6, and the external shrink fit angle is set at 4.5 degrees.

The spindle chuck is compatible with tools made from high-speed steel (HSS) and carbide (HM), offering high flexibility for various machining applications.
