Features and Major Physical Properties SANMODUR LC - M
  • *1 - The board was cut using an NC machine. The Surface roughness of the cut section was measured through the use of non-contact three-dimensional surface roughness tester. The surface roughness is the average absolute value of irregularities; and the lower the value, the smoother the surface is.
  • *2 - The milling resistance during cutting through the use of an NC machine driven with 4-component dynamometer under the following conditions was measured: Edge: throw-away tip of carbide tool with a diameter of 10mm (0.4in), Revolution rate; 10,000 rpm, Feed speed: 2,000 mm/min (6.56 ft/min), Cut depth: 3mm (0.12in).
  • *3 - The board was cut continuously for 10m (32.8ft) using an NC machine under the following conditions; Edge: normal cutting edge of high-speed steel with a diameter of 10 mm (0.4in), Revolution rate: 10,000 rpm, Feed speed: 100mm/min (0.33 ft/min), pitch: 1mm (0.04in), Cut depth: 3mm (0.12in) The degree of abrasion of the cutter edge after cutting was visually evaluated with a stereomicroscope"
