ABSTRACT:
A machining apparatus for forming and cutting workpieces that can prevent the blade thereon from damages. The machining can also precisely form desired patterns on the workpiece and cut the workpiece to desired shape. The machining apparatus contains: a hydraulic cylinder having a stretchable rod at an upper end, means for adjusting a altitude of the hydraulic cylinder, which is engaged with the hydraulic cylinder at a lower portion thereof and means for restraining the hydraulic cylinder can move only vertically. For each operation the stretchable rod will extend to its full extension. Therefore there is no need to adjust the stretching distance for different workpieces. To avoid the damage of the mold blades by over-pressing the blades, a user can use the means for adjusting an altitude of the hydraulic cylinder to adjust the altitude of the hydraulic cylinder. Thereafter the stretchable rod is fully extended, the mold blades precisely form the patterns on a rubber/plastic plate and also cut a desired shape of the rubber/plastic plate.
