The invention relates to an advancing power saw used for any metal cutting application. The power saw (10) is provided with an oscillating mechanism (30) that drives the saw (46) up and down in a vertical direction. A hydraulic cylinder (260, 262) and/or a pulley assembly (194) advances the saw toward the metal being cut while the saw is oscillating creating a circular pathway for the saw blade during the cutting operation. A balancing apparatus (26, 244) is provided in association with the saw blade that advances in an opposite direction to that of the saw blade to act as a counterbalance (146) for the saw. The balancing apparatus has a weight provided at one end which dampens the vibrations created by the saw during the cutting operation and substantially equalizes pressure on the saw blade. For cutting high tensile strength metals having a combustion point within the operating temperatures of cutting apparatus, for example titanium bars, a rotating holder (300) is provided for significantly reducing the cutting time. |
