Marking plateUsed for marking or aligning the position of workpieces:
（1）Marking plateThe structure is mainly composed of a base, columns, marking needles, and clamping nuts.Marking plateThe two ends of the marking needle are divided into a straight end and a curved end. The straight end is used for marking, while the curved end is often used to mark the position of the workpiece, such as finding the parallelism between the workpiece surface and the marking platform surface.
(2) Requirements for using the disc:
①Marking plateWhen the marking needle is firmly clamped and marked horizontally, it should be kept in a horizontal position and not tilted too much. The extended part of the needle should be as short as possible, so that the needle has better rigidity and is less likely to shake. The clamping of the marking needle should also be reliable to avoid any changes in size during the marking process.
② The marking needle should be tilted along the marking direction, and a certain angle (40 °~60 °) should be tilted between the marking needle and the marking surface of the workpiece along the marking direction, which can reduce the marking resistance and prevent the needle tip from piercing the surface of the workpiece. In useMarking plateWhen drawing a long straight line, the segmented connection marking method should be used to check the beginning and end of each segment, avoiding the deformation caused by the elasticity of the marking needle during the marking processMarking plateThe marking error caused by the movement itself.
③ To drag smoothly and tightly against the surface of the tabletMarking plateDuring the marking process, the base needs to be draggedMarking plateWhen using the base, it should be tightly in contact with the platform surface without shaking or jumping. In order to facilitate dragging when drawing lines, it is also required that the contact surface between the base and the platform be kept clean to reduce resistance.
④ When not in use temporarily, the straight end of the needle should be vertically downwardMarking plateAfter use, the needle should be placed in a vertical position with the straight end facing downwards to prevent injury and reduce the space occupied.
