将烧结致密的(NbTaVWMo)C 块状样品粗磨后，在尺寸为250*21*5mm的金刚石磨盘进行精磨，粒度为600目，磨盘转速为300转/min, 载荷为60 N，使用NanoMap500DLS 型接触式轮廓仪通过Spip三维图像处理软件对粗磨后工件表面形貌数据采集，获取三维轮廓和表面粗糙度等信息

After rough grinding the sintered dense (NbTaVWMo) C block sample, fine grinding was carried out on a diamond grinding disc with a size of 250 * 21 * 5mm, a particle size of 600 mesh, a grinding disc speed of 300 revolutions per minute, and a load of 60 N. NanoMap500DLS contact profilometer was used to collect surface morphology data of the rough ground workpiece through Spip 3D image processing software, obtaining 3D contour and surface roughness information.
