Abstract

PURPOSE:To prevent reduction in workability, and to achieve efficient removal of burr by additionally providing a means by which after composition of spot facing the periphery of the machined part is chamfered or by which a chamfering tool is held to the holding spindle of a machining tool, so that chamfering can be enabled by the same machining tool for performing spot- facing. CONSTITUTION:A spindle 14 is turned, and at the same time a motor 11 is operated to lower a tool 15 to a prescribed position, and then the tool is fed into a printed board P up to a prescribed depth. In this condition, a table 4 and a slider 7 are relatively moved for machining a spot-facing hole 24. After completion of the machining of the spot-facing hole 24, the motor 11 is operated to lift the tool 15. Then a motor 8 is operated to move the slider 7 as much as the distance between the axis of the tool 15 and that of a tool 18. Thereafter, a cylinder 16 is operated to lower the tool 18. In this condition, the table 4 and the slider 7 are relatively moved to perform the chamfering of the peripheral part of the spot-facing hole 24, and to perform the removal of burr produced at the time of spot-facing machining.
