Method for producing a composite lubricating material

A thermal pressing machine has a case in which a fixed-side press plate is fixedly provided, a main shaft to which a moving side press plate is attached, a lever arm pivotally attached to the main shaft, a first drive mechanism coupled to a force point at one end of the lever arm, and a second drive mechanism coupled to a supporting point at the other end of the lever arm. The first drive mechanism first causes the lever arm to pivot on the supporting point to greatly move the press plate, and the first drive mechanism is then stopped to operate the second drive mechanism, so that the lever arm pivots on the force point to press the press plate against the press plate.
