Abstract

The invention provides a linear cutting device and method for a PCD bar, which are used for cutting a PCD column sheet into the PCD bar. The linear cutting device comprises a PCD column sheet clampingstructure, a walking mechanism, a controller, a supporting structure and a linear cutting wire fixed to an upper electrode and a lower electrode, wherein the PCD column sheet clamping structure is used for fixing the PCD column sheet; the walking mechanism is used for driving the linear cutting wire to cut the PCD column sheet; the supporting structure is fixed to the walking mechanism; the linear cutting wire penetrates through the supporting structure; the supporting structure is used for supporting the PCD bar in the cutting process; a pressure sensor is arranged on the supporting structure and used for detecting the contact pressure between the PCD column sheet and the supporting structure; the pressure sensor and the supporting structure are both electrically connected to the controller; the controller is used for controlling the supporting structure to ascend or descend according to the magnitude of the contact pressure; and the supporting structure plays a role in supporting the PCD bar in the cutting process, so that the protruding defect generated in the linear cutting process of the PCD bar is avoided.

Description

technical field [0001] The invention belongs to the technical field of diamond tool processing, and more specifically relates to a wire cutting device and method for PCD bar stock. Background technique [0002] Printed Circuit Board (PCB), also known as printed circuit board, is the support of electronic components and the carrier of electrical connection of electronic components. Printed circuit boards have been widely used in the production and manufacture of electronic products middle. PCB drilling is a process of PCB plate making, and it is also a very difficult step in processing. PCB boards place great demands on the wear resistance of drill bits. Conventional carbide drill bits are difficult to meet the requirements of life and drilling quality. [0003] Polycrystalline diamond (PCD) has the characteristics of high hardness, high wear resistance and low friction coefficient, making PCD drill bits an effective solution for drilling difficult-to-machine PCB boards. PC...
