Embodiment Construction

[0072] Figure 1-18 A tool grinder 20 according to a specific embodiment of the invention is described.

[0073] The tool grinder 20 according to the present application is a fully automatic computer numerical control (Computer Numeric Control, CNC) micro-diameter end milling grinder. The tool grinder 20 single-clamping tool fully automatically processes all the steps of end face grinding with small diameter (tool diameter between 0.01 and 2.0mm).

[0074]

[0075] Such as figure 1 As shown, a tool grinder 20 is housed in an equipment housing 12 whose outer surface forms a box shape and is set on a shelf 11 supported by several bases 10 . The center of the front surface of the equipment housing 12 is provided with a front window 13 which has a window portion and can be selectively opened and closed to isolate the grinding machine 20 installed inside the equipment housing 12 . The front of the equipment casing 12 and the right side of the front window 13 are sequentially e...

Abstract

The invention provides a method of adjusting a machine tool. The method adjusts the machine tool so that, in ultra-precision machining of round bar-like work (W), the machine tool can rotate the work (W) while suppressing run-out of the axis of the work (W). In an axis position adjustment step (S5), a side surface of a projection portion of the work (W) held by a work holding mechanism (50) is measured while a work spindle (40) is rotated. A C-shaft adjustment screw (42b) is adjusted so that run-out of the work (W) is minimum and then the position of the work axis (C2) is fixed. In a support adjustment step (S6), with the position of the work axis (C2) fixed, a support block (91) is adjusted so as to support the work (W). In a support locking step (S7), the definition of the position of the work axis (C2) defined by the support block (91) is maintained by pressing the work (W) by a work presser (92). In a floating-restriction releasing step (S8), floating restriction by the C-axis adjustment screw (42b) is released.

Description

technical field [0001] The invention relates to a machine tool adjustment method and a machine tool, in particular to the centering adjustment of workpieces of tool grinding machines such as grinding and processing small-diameter end mills. Background technique [0002] In recent years, for ultra-precision machining tools, such as micro-diameter end mills with a diameter of about 0.01 to 1.00 mm, there has been an increasing demand for even more precise tool machining. Machining tools with such a small diameter requires mounting strip-shaped workpieces composed of cemented carbide and high-speed tool steel, etc., in the work chuck of the tool grinder. Then, the workpiece is ground while rotating it around the axis to form the desired shape of the tool. [0003] In this case, if the workpiece is supported by a cantilever method such as a collet chuck, the support of the workpiece becomes unstable. This creates vibrational noise when grinding the workpiece. That is, the wor...
