Abstract (en)

The present invention provides a linear motor mounted press machine that allows both a punch and a die to be driven to enable various types of machining, the linear motor mounted press machine having a simple configuration and enabling accurate machining. The present invention is applied to a press machine that performs a press working on a workpiece W by means of a punch 61 and a die 62. A punch linear motor 1 is installed in an upper frame 41b of a press frame 41 to drivingly elevate and lower the punch 61. A die linear motor 1A is installed in a lower frame 41c of the press frame 41 to drivingly elevate and lower the die 62 (Fig.1).
