MECH 200 1st Edition Lecture 8Saw Blade Types• Buttess• Claw Hook • Carbide Tipped – the carbide cutting portion is braised on above 800 deg F• Skip Tooth – Makes room for the swarthe/chips• Hook Tooth – Best for wood and meatBlade Terminology1. Set – Pattern of Bladed Teetha. Raker (removes swarthe)b. Straight2. Kerf – width of set (Wider than blade)3. Pitch – Teeth/incha. There are variable pitch blades which have multiple pitches in one blade4. Friction Cutting – a blade with no teeth is used5. Gang Sawing – Multiple saws built into one assembly6. Circular Saw – Circular blade7. Cold Saw – Slow moving circular blade with coolant used in the processThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Setting up Cutting – three teeth minimum should be in contact at all times• This is why flat stock should be cut horizontallyCutting Fluid – 1) Purposea) Helps remove swarthe from kerfb) Cools blade and work piecec) Lubrications: Reducing power consumption and extending blade lifei) Applications(1) Flood(2) Spray (3) Mist – Compressed air achieves this(4) Brush – Most Dangerous(5) Micronizing – Computer delivered and most precise2) Types of Cutting Fluida) Compressed Airi) Blows chips awayii) Cooling: lowiii) Excellent for Cast Iron, Brass and Bronzeb) Waxesi) Cooling: noneii) Lubrication: Goodiii) Prevents chips from stickingc) Cutting Oili) Lubrication: Excellent – Goodii) Can Smokeiii) Cooling: Poor – Averageiv) Sulpherized is not user friendlyd) Emulsifiable (H2O Soluble)i) Economicii) User Friendlyiii) Cooling: Excellentiv) Lubrication: Poor – Averagee) Synthetici) Expensiveii) Lubrication: Bestiii) Cooling: Moderate -
