KARAKTERISTIK AUS PISAU PENGERJAAN KAYU KARENA PENGARUH EKSTRAKTIF DAN BAHAN ABRASIF YANG TERKANDUNG PADA KAYU DAN KOMPOSIT KAYU
ABSTRACT: This paper presents
the effect of extractive and abrasive material of tropical timber (Damar Laut,
Mersawa, and Oil Palm wood) and of composite products (Fiber Board and Cement
Board) on the wearing of high speed
steel and tungsten carbide cutting tools. The extractive content provides a
significant contribution on the chemical wearing of the cutting tools. Oil palm
wood and Mersawa wood contain extractives which are more corrosive compared to
other wood species tested. Mechanical wear
resistance is influenced by the abrasive material contained in the wood,
especially silica, both in wood and wood composite products. Mersawa wood
caused the cutting tools wear faster than other types of solid wood. Cement
board as a composite product caused the damaged of the cutting edge of high
speed steel tool due to high abrasive materials contained in the the cement
board. Tungsten carbide tool has higher wear resistance than high speed steel
tool.
