现在, 由于晶体材料自身固有的限制, precision cutting processes can be classified into reciprocating and circular types based on the movement of the cutting wire. Reciprocating cutting involves complex winding and unwinding devices. 此外, the reciprocating change in cutting direction during the cutting process reduces the surface quality of KDP crystals, while the cutting speed is also limited, resulting in low cutting efficiency.
然而, circular cutting technology can overcome these drawbacks. It offers advantages such as narrow cutting seams, high processing quality, and high processing efficiency. This technology holds broad application prospects in the field of cutting hard-to-process materials.
Cutting method
Compared to reciprocating cutting machines, the development of circular cutting technology is still not very mature. Current companies such asEnsolltools工具and diamondwirete are involved in this field, and there is significant diversity in the structure of circular cutting equipment.
This article, based on the processing requirements of crystal materials, has designed a new generation of electroplated diamond circular precision cutting machine. By utilizing grey relational theory methods to optimize multiple parameter factors in circular cutting, it has determined the comprehensive impact of various process factors on the degree of cutting surface quality and the optimal cutting process parameters.
A Brief Analysis of Circular Cutting Technology Operation
例如, with dimensions of 1,400 mm × 1,400 mm × 1,600 毫米. The overall structure of the machine tool is arranged in a T-shaped configuration, with the bed, columns, and Z-axis slide plate all made of highly stable natural granite material, providing excellent damping characteristics. The circular cutting device module is fixed on the Z-axis column slide plate.
To minimize the impact of cutting on flatness during the machining process, the Z-axis linear movement unit is composed of high-precision linear guide pairs and ball screw pairs, offering good responsiveness and high positioning accuracy. The servo motor driving the movement unit provides feed speeds ranging from 0 自 20 m/min. The bed is equipped with a Y-axis manual feed device to strictly control the installation accuracy of the Y-axis guide pairs and screw pairs in order to ensure the thickness of the slices.
此外, to ensure feed positioning and repeat positioning accuracy, 移动单元配备了光栅位移传感器. 由于切割KDP晶体材料的晶面硬度存在各向异性, Y轴进给装置配备了可调转台, 允许根据要求调整切割角度，无需拆卸工件. 该机床也适用于各种非金属的高精度切割, 硬脆陶瓷材料, 最大切割尺寸为 200 mm × 200 毫米.
结论
基于使用电镀金刚石圆盘切割机切割KDP晶体的实验, 得出以下结论:
(1) 超精密电镀金刚石圆盘切割机表现出优异的切割特性. 在切割KDP晶体时, 切片的表面质量显著提高, which is more conducive to subsequent processing optimization. The diamond circular cutting machine is a cutting technology with great development potential.
(2) Different process parameters have varying degrees of influence on the flatness and surface roughness of the workpiece. The grey theory method effectively analyzed the impact of each process parameter on the surface quality of cutting KDP crystals, ranking the influence in the following order: feed speed, circular line speed, tension force. Unlike高纯度石英, KDP is water-soluble and needs a completely different cutting strategy.
