Claim Text:
1. An ingot cutting apparatus including a cutting table on which an ingot is horizontally placed, and an endless-belt blade provided in a tensioned state between pulleys, the blade having a blade-abrasive-grain portion and a blade base, the ingot cutting apparatus cutting the ingot by relatively feeding the blade from above to below against the ingot while driving to rotate the blade by rotating the pulleys and supplying a coolant to the blade, the ingot cutting apparatus comprising at least two coolant pockets storing the coolant to be supplied to the blade and a pair of static pressure pads having coolant-spraying outlets through which coolant is sprayed toward the blade, the static pressure pads being arranged opposite one another at a predetermined interval so as to allow the blade to pass through, wherein the blade-abrasive-grain portion is brought into contact with the coolant stored in the at least two coolant pockets by causing the blade-abrasive-grain portion of the blade to travel through a groove portion provided at an upper portion of the at least two coolant pockets while driving to rotate the blade so that the coolant is supplied to the blade-abrasive-grain portion of the blade, the at least two coolant pockets are arranged below the static pressure pads, and the coolant sprayed through the coolant-spraying outlets of the static pressure pads is stored in the at least two coolant pockets, wherein at least one of the at least two coolant pockets is arranged at respective positions of a front and a rear of the ingot with respect to a direction of driving to rotate the blade, and wherein a number of the coolant pockets is the same as a number of the arranged static pressure pads.
