Features and Major Physical Properties of Product

• *1 - The board was cut using an NC machine. The surface roughness of the cut section was measured through the use of a 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.
• *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: through-away tip of carbide tool with a diameter of 16 mm, Revolution rate: 5,000 rpm, Feed speed: 2,000 mm/min, Cut depth: 3 mm
• *3 - The board was cut continuously for 10 m using an NC machine under the following conditions: Edge: normal cutting edge of high-speed steel with a diameter of 10 mm, Revolution rate: 10,000 rpm, Feed speed: 100 mm/min, Pick: 1 mm, Cut depth: 3 mm The degree of abrasion of the cutter edge after cutting was visually evaluated with a stereomicroscope (magnification: 50).
• *4 - A test piece of 50 (w) × 50 (d) × 120 (h) mm measured height after kept for 12 hours at 25 ℃ in air, and soaked for a few days in water at 50 ℃.Then kept for 12 hours in water at 25 ℃, and mesured height. Rate of water expansion was calculated using its two heights.

 

                                     Rate of Water Expansion at 50℃(%)

Features
