Abstract
Official abstract text for this publication.
A machine tool includes a tool main spindle device to execute machining of a first system in a first workpiece main spindle device for rotationally holding a workpiece and machining of a second system in a second workpiece main spindle device for rotationally holding the workpiece by an exchangeable main spindle head tool. Drive control of each device is performed by a control device, the control device including a tool management processing section to calculate a total usage time of the main spindle head tool based on the machining of the first system or the machining of the second system executed in the tool main spindle device, to store the calculated total usage time as first tool management data or second tool management data, and to rewrite the same total usage time in the other of the second tool management data or the first tool management data.
First claim
Opening claim text (preview).
1 . A machine tool comprising: a tool main spindle device configured to execute machining of a first system in a first workpiece main spindle device configured to rotationally hold a workpiece and machining of a second system in a second workpiece main spindle device configured to rotationally hold the workpiece by an exchangeable main spindle head tool, wherein drive control of each device is performed by a control device, wherein the control device has a tool management processing section configured to calculate a total usage time of the main spindle head tool based on the machining of the first system or the machining of the second system executed in the tool main spindle device, to store the calculated total usage time as first tool management data or second tool management data, and to rewrite the same total usage time in the other of the second tool management data or the first tool management data. 2 . The machine tool according to claim 1 , wherein the tool management processing section of the control device calculates a machining time period during which the main spindle head tool actually contacts a workpiece from information of a machining program for executing the machining in the first system or the second system. 3 . The machine tool according to claim 1 , wherein the tool management processing section of the control device reads the total usage time of the main spindle head tool calculated and stored according to the machining of the first system or the second system from a first one of the stored first tool management data or the stored second tool management data, and writes the total usage time in the other of the second tool management data or the first tool management data as the total usage time in the main spindle head tool. 4 . The machine tool according to claim 1 , wherein the tool management processing section of the control device rewrites the total usage time of the main spindle head tool every time the machining program in the first system or the second system is finished.
