Doctoral thesis on this issue have brought powder tungsten carbide produced from scrap knives lathe (Tool Insert Scraps) is a raw material in the production of plates, knives, lathe Re-Sintering way, from a contents preparing metal powders, has less than 5 µm after mixing 10% cobalt, extrusion and then study the temperature to bake different mailing. Found that baking at the temperature from 600 to seal rubbing a min 60 ˚ C ˚ C 1150, a 30-min, 60 ˚ C and min 1450 time piece that has a hardness of 1, 500 HV 358.6 ˚ C temperature if using for a period of 60 min, 30 min 800 ˚ C ˚ C, 1220 45 min and 90 min time ˚ C 1410 have slices. 346.3, with a hardness HV 1 and use of accessories.Nahaphumi at 500 min 60 ˚ C ˚ 830 for a period of time, C 10 min, 10 min time C ˚ 1200 and 1450 ˚ C for a period of 60 min piece is solid 1, 399.5 HV respectively. It appears that the comma structure a little bit about a 0.1-6.0 µm the grainy structure that looks different is the result of the size and distribution of metal powders and baking to seal at different temperatures. However, the strength of the relationship is both Route 3, which is associated with surface wear Dodge (Flank Ware) between 1.26-1.68 mm S45C steel skin peeling when kluek the resolution (50 m/min Cutting Speed Feed rate mm/sec, 0.1, 1.0 mm Depth of Cut) size of surface roughness (Ra) has a value of 4.57 µm will confirm your ability to produce the knife plate Re-Sintering plate lathe knife, which was found to have a bit of structure and hardness standards. The trial results is a prototype for the development of tungsten carbide knives, plates, and more qualified to apply to the next job.
