Embodiment Construction

[0038] An embodiment of the present invention will be described below with reference to the drawings.

[0039] Such as figure 1 with figure 2As shown, the machine tool 1 includes: an iron base 2 , a machine tool body 3 arranged on the base 2 , and a protective baffle 4 covering the machine tool body 3 . A front opening (not shown) is provided on the front surface of the protection baffle 4 . A pair of sliding opening and closing doors 5, 6 are arranged at the front opening. Rectangular glass window portions 5a, 6a are provided approximately at the centers of the opening and closing doors 5, 6, respectively. A handle portion 5 b is provided at the right end portion of the opening and closing door 5 , and a handle portion 6 b is provided at the left end portion of the opening and closing door 6 .

[0040] The machine tool 1 performs desired cutting processing on the workpiece by relative movement of the workpiece and the tool. An operation panel 10 for operating the machin...

Abstract

The invention provides a control device of a machine tool, which controls electrifying to the machine tool. The control device keeps electrifying of a second relay in a scheduled time by a capacitor of a power source monitoring part arranged in the control device when voltage of a factory power source electrifying the machine tool is lost. After voltage of a factory power source electrifying the machine tool is lost for the scheduled time, the second relay is used to record electrifying history. When the machine tool is started again, a CPU reads data electrifying history equivalent to electrifying of the second relay and limits starting when having detected the history.

Description

technical field [0001] The present invention relates to a control device for a machine tool that controls energization to the machine tool. Background technique [0002] In the past, machine tools requiring precise machining by operators needed to maintain precision. For example, when a machine tool is significantly moved due to relocation or resale, technical personnel at machine tool manufacturing companies, etc., need to check to ensure performance. As a prior art for detecting the transfer or resale of the machine tool, and notifying and warning the operator, there is, for example, the technology described in Japanese Patent Laid-Open No. 35595 in 2003. [0003] In this prior art, the vibration detection mechanism detects that the machine tool is vibrated. The vibration history storage means stores the presence or absence of detected vibration as a vibration history. When the vibration history is stored in the vibration history storage means, the machine tool notifies...
