Abstract
Block-cutting gangsaw with vertical frame for cutting granite or other hard materials, comprising a blade-holding frame (19) that is supported with the possibility of reciprocating movement on an independent oscillating frame (40) which imparts the oscillating movement to it, so that each blade (20) of blade-holding frame (19) is always in contact with workpiece (18), and the contact area moves along a convex, curved trajectory.
Claims12
A block-cutting gangsaw with vertical frame for cutting a block of granite or other hard material, comprising:
- a blade-holding frame, the frame adapted to undergo reciprocating and oscillating motion so as to determine a curved cutting trajectory on the block,
- wherein the blade-holding frame is further adapted to undergo reciprocating movement on an independent oscillating frame which imparts the oscillating motion, so that each blade of the blade-holding frame is always in contact with the block, and
- wherein a contact area between the blade-holding frame and the block moves along a convex, curved trajectory.
