Abstract
Official abstract text for this publication.
Provided is a replaceable machining head wherein: fractures on the tool attaching portion do not occur; the production cost is minimized; the tool life of the working tool will be lengthened; and the head body is free from a risk of falling off during replacement. In the replaceable machining head, a cutting edge section is formed on the front side of a head body; a tool attaching portion to which a working tool is to be attached, is formed on the rear end side of the cutting edge section; tool attaching faces are formed in the tool attaching portion; the surface of the head body 1 is coated with a coating film; and the number of droplets or macro particles having convex shapes with a size of 0.3 μm to 5.0 μm, is 200 or less, per area of 40 μm×60 μm on the surface of the coating film over the tool attaching faces.
