Abstract
The invention refers to a method for cutting blocks of stone (12), by means of a gangsaw (1) provided with diamond sector blades (35), comprising, besides a reciprocal approaching movement between the blades (35) and the block (12) and a periodical reciprocating movement of the blades (35), also a cyclic movement of approaching and moving away of the blades (35) relative to the block (12) and a hunting movement of the blade-holder frame. (FIG. 1)
Claims15
A method for cutting blocks of stone, conglomerate or concrete into slabs or blocks by means of a gangsaw (1) provided with blades (35) having sectors containing abrasive material and with a water cooling and lubricating system, comprising the steps of:
- providing a reciprocal approaching movement between said blades (35) and said block (12), and
- providing a periodical longitudinal reciprocating movement of said blades (35) relative to said block (12), and
- providing a cyclic movement of approaching and moving away of said blades (35) relative to said block (12), in a direction substantially perpendicular to the direction of said periodical reciprocating movement and independently from said reciprocal approaching movement.
Method according to any one of the preceding claims, in which the travel of the blades (35), during the periodical longitudinal reciprocating movement, is inclined in a first direction (8′) not parallel to the base of the block (12) during a forward movement of the blades (35) and is inclined in a second direction (8″) opposite to the first direction during a reverse movement of the blades (35).
A frame cutting machine (1) for cutting blocks of stone, conglomerate or concrete into slabs or blocks, comprising:
- a supporting structure (2, 4, 6) for supporting, by means of longitudinal sliding guides (8), a blade-holder frame (10, 11, 52) coupled to means for motion generation and transmission (30, 32, 26, 28) suitable for moving the blade-holder frame in a periodic reciprocating movement along predetermined paths,
- a plurality of parallel blades (35) set in said blade-holder frame and containing abrasive material, and
- a reciprocal approaching system between said blade-holder frame and said block (12),
- wherein the frame cutting machine comprises a cyclic movement system (40;
- 50) of approaching and moving away of said blade-holder frame relative to said block (12), in a direction substantially perpendicular to the direction of said periodical reciprocating movement of the blades and independently from said reciprocal approaching movement.
A frame cutting machine (1) for cutting blocks of stone, conglomerate or concrete into slabs or blocks, comprising:
- a supporting structure (2, 4, 6) for supporting, by means of longitudinal sliding guides (8), a blade-holder frame (10, 11, 52) coupled to means for motion generation and transmission (30, 32, 26, 28) suitable for moving the blade-holder frame in a periodic reciprocating movement along predetermined paths,
- a plurality of parallel blades (35) set in said blade-holder frame and containing abrasive material, and
- a reciprocal approaching system between said blade-holder frame and said block (12), wherein the frame cutting machine comprises a cyclic movement system (40;
- 50) of approaching and moving away of said blade-holder frame relative to said block (12), in a direction substantially perpendicular to the direction of said periodical reciprocating movement of the blades and independently from said reciprocal approaching movement;
- and
- wherein the blade-holder frame comprises a first part (10) suitable for supporting the blades (35) and the corresponding tensioning mechanisms (37), and a second part (11) coupled to said means for motion generation and transmission suitable for transferring the reciprocating movement to said first part (10), said first (10) and said second (11) part of the blade-holder frame being connected together in order to allow, cyclic approaching and moving away movements of said first part relative to the block (12).
