    • XL-UL UL規(guī)格試料磨平機(jī) 本機(jī)在將橡膠或塑膠啞鈴狀試片磨平、磨薄或磨出所需之厚度，以供拉力、老化、耐油等試驗(yàn)之用。試片臺(tái)左右、上下及前后之移動(dòng)，以扳手操作。 符合UL1581標(biāo)準(zhǔn)第420.6條規(guī)定。 Buffing machine （AUGUST 2, 2006 - UL 1581） 420.6 A power-driven buffing machine (grinding wheel) is appropriate for buffing irregularities from the samples from which die-cut specimens are to be prepared. The abrasive wheel is to be of about No. 36 grit (particle size of 0.019 inch or 0.486 mm). The wheel is to run true and is not to vibrate. The diameter of the wheel is not specified; however, 4-3/4 – 6-1/4 inch or 0.12 – 0.16 m has been found appropriate. The rotary velocity of the wheel is to be 2500 – 3500 r/min. The diameter and rotary velocity of the wheel are to be selected to give the wheel a peripheral speed (rpm×p×wheel diameter) of 3000 – 5000 ft/min or 15 – 25 m/s. CAUTION – The maximum wheel diameter stated in this paragraph and the maximum wheel rpm stated in this paragraph shall not be used together as this combination will result in a peripheral speed above 5000 ft/min or 25 m/s. This applies even for wheels that are marked as being intended for a peripheral speed above 5000 ft/min or 25 m/s. The machine is to have a slow feed that applies light pressure and removes very little material at one cut, thereby not overheating the specimen or the wheel. 主要技術(shù)參數(shù) 砂 輪：36#； ø 6″ 砂輪線速度：3000～5000feet/min或15～25m/s 皮帶輪加速比：2：1 體 積：50×60×40cm 重 量：50kg 電 源：1∮，AC220V 50Hz
