Requirements for PCD cutting tool grinding


2021-08-16


Demina has produced PCD cutting tool grinding for more than 10 years. Their tool grinder has advantages as below.

(1) The machine has good process system rigidity.

Due to the high hardness of PCD materials, the grinding machine must have high deformation resistance, especially spindle system and tool clamping system.The grinding force of PCD cutting tool is usually 100 ~ 500N.Therefore, it is required that the shaft diameter of the machine tool is large, the axial rigidity and strength of the bearing are high.

(2) The machine tool has a short-range swing mechanism with adjustable stroke and speed.

PCD has a very low grinding ratio. The grinding mechanism of PCD is mainly the result of the mixing of mechanical action, such as micro-crushing, wear, peeling and cleavage, etc. formed by the continuous impact of diamond grinding wheel on PCD material, and the thermochemical action of oxidation and graphitization.Therefore, adopting short-range swing mechanism is beneficial to improve grinding efficiency and cutting edge quality.General swing distance 0 ~ 50mm, swing speed 20 ~ 60 times/min.

(3) The tool holder of the machine tool has high precision rotary function and online testing device.

Because the PCD material is hard, brittle and wear resistant, the tool tip is usually designed as an arc to help reduce the amplitude of the relative vibration between the tool and the workpiece.In order to realize the machining of the tool point arc, the tool holder of the machine tool should have high precision rotary function and the tool point arc radius size and quality online detection device.In this way, the positioning error brought by multiple loading can be avoided, and the processing efficiency can be multiplied.
