特點(diǎn) 采用天然花崗巖材料，可確保性能和尺寸的穩(wěn)定性。 花崗巖平臺(tái)的性能在很多方面優(yōu)于鑄鐵平臺(tái)：硬度是鑄鐵的兩倍。尺寸受溫度影響小。 無扭曲變形，不會(huì)影響工作。 由于花崗巖平臺(tái)的晶體結(jié)構(gòu)精細(xì)，無粘滯性，不會(huì)產(chǎn)生毛刺或表面凸起現(xiàn)象，因此可保證長期使用也可確保很高的平面度，不會(huì)損壞工件或儀器。 磁性材料的應(yīng)用實(shí)現(xiàn)了無故障操作。 使用壽命長而且不會(huì)生銹，維修成本較低。 可選用鋼制臺(tái)架。性能參數(shù)等級(jí)00尺寸(WxDxH) 貨號(hào)* 平面度300x300x100mm 517-401 0.002mm450x300x100mm 517-411 0.002mm600x450x100mm 517-414 0.0025mm600x600x130mm 517-403 0.0025mm750x500x130mm 517-405 0.003mm1000x750x150mm 517-407 0.003mm1000x1000x150mm 517-409 0.0035mm1500x1000x200mm 517-413 0.004mm2000x1000x250mm 517-410 0.0045mm2000x1500x300mm 517-416 0.005mm2000x2000x300mm 517-417 0.0055mm3000x1500x400mm 517-418 0.0065mm3000x2000x500mm 517-419 0.007mm等級(jí)0尺寸(WxDxH) 貨號(hào)* 平面度300x300x100mm 517-301 0.003mm450x300x100mm 517-311 0.003mm600x450x100mm 517-314 0.004mm600x600x130mm 517-303 0.005mm750x500x130mm 517-305 0.005mm1000x750x150mm 517-307 0.006mm1000x1000x150mm 517-309 0.007mm1500x1000x200mm 517-313 0.008mm2000x1000x250mm 517-310 0.010mm2000x1500x300mm 517-316 0.010mm2000x2000x300mm 517-317 0.011mm3000x1500x400mm 517-318 0.013mm3000x2000x500mm 517-319 0.014mm等級(jí)1尺寸(WxDxH) 貨號(hào)* 平面度300x300x100mm 517-101 0.005mm450x300x100mm 517-111 0.006mm600x450x100mm 517-114 0.008mm600x600x130mm 517-103 0.008mm750x500x130mm 517-105 0.009mm1000x750x150mm 517-107 0.012mm1000x1000x150mm 517-109 0.013mm1500x1000x200mm 517-113 0.016mm2000x1000x250mm 517-110 0.019mm2000x1500x300mm 517-116 0.020mm2000x2000x300mm 517-117 0.022mm3000x1500x400mm 517-118 0.025mm3000x2000x500mm 517-119 0.027mm
