The cutting machine is mainly composed of these parts: handwheel, three-head screw rod, base, spring, shaft, shaft support, platform.
A three-head screw rod is installed in the screw hole of the fuselage. The upper end of the screw rod is equipped with a handwheel, which is used as a rotating screw. The lower shaft frame is fitted with a sliding shaft. The upper end is tightened by a spring. The lower platform can be replaced with different dies cutters. When the handwheel is rotated, the three-head screw drives the cutter through the sliding shaft, which can make the reciprocating motion to achieve the purpose of punching the test piece.
