Spindle chuck with ISO30 conical shank, manufactured according to DIN7388 (DIN69871), are designed to accommodate cylindrical shank cutters of different diameters and with Weldon shank. Spindles with the same cutter housing diameter but with a variable length of your choice are also available. This wide choice has been made necessary to allow the end user to access milling cutters even in spaces that are not always accessible or have a large footprint that is difficult to access with the machine tool.

The precision and construction of the ISO 30 spindle, which is designed to mount milling cutters or tools with a cylindrical or Weldon shank, has been realised with a balance and concentricity between the ISO 30 taper and milling cutter shank axes equal to G6.3, which can rotate up to a maximum of 15,000 rpm.

With these special features, it is possible to use the spindle with cutter types having different carbide characteristics and different coatings, thus allowing optimisation of cutting speed and cutting feed parameters and for optimize chip removal machining on all materials.

The holder’s manufacturing quality is ensured by a precision tolerance of 0.005 mm (5 µm), referring to the radial runout / concentricity of the tool seat relative to the rotation axis. In practice, during rotation the end mill will not “wobble” by more than 0.005 mm, resulting in improved stability, a more consistent surface finish and better repeatability in milling operations, while reducing vibration and tool wear.

Cutter chucks with ISO30 conical shank made according to DIN7388 (DIN69871),, also have the central and on-flange (AD) coolant passage system, so as to optimize the cooling of the cutter and chip removal through the coolant passing through the central hole of the chuck.

For machines that have an automatic tool changer, the spindle has the M16 thread and diameter the housing for different tie-rods an example of which is shown below, made to drawing for different types and models of machine tools such as Kitamura, Hurco, Jis-B6339, Mazak, ISO7388, DIN69872, all with or without coolant passage. These products are available and sold by Tadaah in the category of accessories.
