Abstract: To provide a machine tool capable of processing a work to have a required thickness based on a simple structure without adjusting a distance itself between both cutting tools. A machine tool includes: a spindle rotating around a Z-axis extending in a horizontal direction; a tool post disposed in a movable manner in the Z-axis direction and an X-axis direction orthogonal to the Z-axis direction and in a pivotable manner around a B-axis orthogonal to a plane face containing the X-axis and the Z-axis; a tool having a pair of tips disposed to have a predetermined interval therebetween and fitted to said tool post; and a tool post control unit adjusting a pivot angle of said tool post so that an angle ? between a straight line connecting the pair of tips and the Z-axis comes to an angle corresponding to a finished thickness of a work.

Abstract: A lathe each or lathes of a machining system comprises a head stock, which is transferred on a rail mechanism. The rail mechanism includes a vertically guiding rail which is mounted on a horizontally guiding rail. A turret has a turret support which has a pair of turret support attaching surfaces. The turret is attached with either of turret support attaching surfaces. A extruded horizontally guiding rail is located between both the bed bodies, each of which is included in each of the lathes. The extruded horizontally guiding rail is identical with a connecting guiding rail which connects the one horizontally guiding rail of the one lathe with the other horizontally guiding rail of the other lathe. A work stocking means is located between the bed bodies. A reversing means for reversing works is provided with the head stock.

Abstract: The present invention relates to a numerically-controlled lathe, a numerically-controlled device therefore and a procedure for processing a workpiece thereby. An object of the invention is to provide a numerically-controlled lathe adapted to designate one of two spindles and three tool rests and a procedure for processing a workpiece thereby.

Abstract: An apparatus for setting a work coordinate system of a machine tool is disclosed. A work coordinate system is set on the basis of a position from the surface to be machined of a work by automatic input of a tool mounting dimension. The apparatus is composed of a means for inputting/outputting machining data, an instrumentation means for measuring the positon of a blade tip of a tool, a tool reference point setting data memory for storing tool reference point setting data, an NC machining program data memory for storing an NC machining program for machining a work, a first processor for operating the tool reference point setting data and the machine coordinate value data to obtain the mounting dimesion data for each tool, and a second processor for obtaining work coordinate system data and the tool mounting dimension data.
