Adjustable cutting tool assembly
Abstract
Abstract ROTARY CUTTING TOOLS SUCH AS ARE USED FOR BORING, MILLING AND SLOTTING ARE MOUNTED FOR LONGITUDINAL AXIAL ADJUSTMENT IN ROTARY CUTTING MACHINE TOOLS BY SECURING THE CUTTING TOOL IN AS TOOLHOLDER BY MEANS OF A SET SCREW WHICH IS CANTED TOWARD THE HEAD OF THE TOOLHOLDER. THE SET SCREW SEATS AGAINST A FLAT SET-FACE THAT IS SLOPED TO PRESENT A PLANAR FACE NORMAL TO THE AXIS OF THE CANTED SET SCREW AND OF SUFFICIENT LENGTH TO PERMIT SEATING OF THE SET SCREW ALONG A DEFINITIZED LENGTH OF THE CUTTING TOOL. THE SLOPED SET-FACE MAY BE CUT INTO THE SIDE FACE OF THE CUTTING TOOL OR INTO A KEY ADAPTED TO FIT AGAINST THE UNSLOPED SET-FACE OF CONVENTIONAL COMMERCIAL CUTTING TOOLS. THE TOOL HOLDER IS PROVIDED WITH AN ADJUSTABLE LIMIT BOLT FOR DEFINING THE DEPTH TO WHICH THE CUTTING TOOL CAN BE INSERTED INTO THE SOCKET OF THE TOOLHOLDER.
