摘要： A tool holder has a cutter arbor. The cutter arbor has a shank portion detachably mounted on a spindle, and a mechanism for holding a cutting tool. In the cutter arbor portion, a cavity portion is formed. In the cavity portion, a vibration damping material is filled at a filling rate so as to be capable of obtaining predetermined vibration damping characteristics. Thus, it is possible to provide high vibration damping characteristics, effectively damp vibrations during cutting and improve working precision, without using any special materials, such as damping materials, although the tool holder has a usual shape.

摘要： A method for machining a slide core hole in a mold and a measurement/correction system for use in machining of a slide core hole. A spindle head is pivoted to meet the inclination angle of the slide core hole to be machined in the mold. A shallow flat-bottomed spot-faced hole is spot-faced in the surface of the mold. A guide hole is drilled in the bottom surface of the spot-faced hole. A rod hole is drilled using the guide hole as a guide. An intermediate pocket hole is formed while expanding the spot-faced hole. A reference point is corrected based on measurement of the shape of the intermediate pocket. A corrected machining program is executed with the corrected reference point to carry out precision shaping machining of the core pocket while expanding the intermediate pocket.

摘要： A numerical controlling unit includes: an inputting part into which a machining program is inputted; an analyzing part that analyzes the machining program to generate an instructed spindle rotational speed and calculates a spindle load ratio of a load applied to a spindle under a machining condition according to the machining program to a spindle load caused when the workpiece is machined: and a distributing part that generates, based on the machining program, a distribution amount per unit period inputted into a feed-axis servo driver. A spindle-rotational-amount-command outputting part receives the instructed spindle rotational speed and outputs a spindle-rotational-amount command for commanding a rotational amount per unit period which is inputted into a spindle driver. A cutting-load-for-judgment calculating part calculates a reference torque value based on the spindle load ratio, the distribution amount, and the spindle-rotational-amount command. A spindle-load comparing part compares the reference torque value with a load torque value which is feedback inputted by the spindle driver and outputs a tool-breakage detecting signal when the load torque value is higher than the reference torque value.

摘要： A machining method of a press die having a pierce cutter and a secondary relief-clearance area recessed inward relative to a profile of the pierce cutter is provided. A plunge cutting tool having a tool body and at least one edge portion provided on an outer circumference of an end of the tool body is used, the edge portion being protruding from the outer circumference of the tool body and being capable of carving while rotating around an axis of the tool body and moving in an axial direction of the tool body. While rotating the plunge cutting tool with an axis of the tool body being approximately parallel to a surface of the pierce cutter, the plunge cutting tool is relatively moved along the profile of the pierce cutter. The plunge cutting tool is also relatively moved in the axial direction of the tool body along the shape of the pierce cutter and the secondary relief-clearance area in a piercing direction each time the plunge cutting tool is relatively moved by a predetermined pitch.
