1　前言近年来,自然类板岩的国际市场需求日益增高,我国具有丰富的石料资源,关键是要加工成等厚的规格板出口。而板岩自然层厚极不均匀,加工成等厚板的平均磨削量在3mm±,切削量大,造成金刚石切削具消耗大;若切削具性能与石材性能不匹配,或与加工设备不匹配,又会造成切削具非正 1 Foreword In recent years, the demand for natural slate in the international market is increasing day by day. Our country is rich in stone resources. The key point is to process the export of plate with the same thickness. The natural thickness of the slate is very uneven, processed into an equal-thickness plate thickness of 3mm ±, large amount of cutting, resulting in expensive diamond cutting tools; if the cutting performance does not match with the performance of the stone, or with the processing equipment is not Matching, will result in non-positive cutting
