Abstract

The invention provides a wire cutting device and method for PCD bar material, which is used for cutting a PCD column sheet into a PCD bar material. The wire cutting device includes a PCD column clamping structure, a traveling mechanism, a controller, a supporting structure and a fixing For the wire cutting wire on the upper electrode and the lower electrode, the PCD column clamping structure is used to fix the PCD column, the traveling mechanism is used to drive the wire cutting wire to cut the PCD column, and the support structure is fixed on the traveling mechanism, The wire cutting wire passes through the support structure, the support structure is used to support the PCD bar during the cutting process, the support structure is provided with a pressure sensor, the pressure sensor is used to detect the contact pressure between the PCD column and the support structure, the pressure sensor and the support The structures are all electrically connected to the controller, and the controller is used to control the rise or fall of the support structure according to the size of the contact pressure. The support structure supports the PCD bar during the cutting process, avoiding the protruding defects of PCD bar wire cutting. produce.

Description

technical field [0001] The invention belongs to the technical field of diamond tool processing, and more particularly relates to a wire cutting device and method for PCD bar material. 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 of electronic products. middle. PCB drilling is a process of PCB plate making, and it is also a very difficult step to process. PCB sheets have huge requirements 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 coefficient of friction, making PCD material drills an effective solution for drilling difficult-to-machine PCB sheets. PCD ma...
