Abstract
A thermal cutter for cutting with heat a board mounted upon a table having an internal space includes a plurality of walls and a sound absorbent material. The walls are disposed in the internal space of the table to partition a plurality of exhaust chambers with each of the exhaust chambers having an aperture that opens towards a side on which the board is mounted. The sound absorbent material is provided to at least a portion of at least one of the walls, the sound absorbent material being removably coupled to the table.
Claims20
A thermal cutter for cutting a board with heat, the thermal cutter comprising:
- a table on which the board is mounted;
- a cutting head configured and arranged to cut the board;
- a first axis shift unit movably supporting the cutting head to shift along a first axial direction parallel to a mounting surface of the table on which the board is mounted;
- a second axis shift unit movably supporting the first axis shift unit to shift with respect to the table along a second axial direction orthogonal to the first axial direction and parallel to the mounting surface;
- a cover unit coupled to the second axis shift unit and moveable together with the second axis shift unit in the second axial direction, the cover unit including a front cover portion and a rear cover portion, the cover unit at least partially defining a shiftable space within which the cutting head is disposed during cutting, the shiftable space extending approximately over an entire shiftable range of the cutting head in the first axial direction, the front cover portion of the cover unit including a first cover plate and a second cover plate, the second cover plate being disposed below the first cover plate and pivotally connected to the first cover plate via a hinge;
- a plurality of walls disposed in an internal space of the table to partition the internal space into a plurality of exhaust chambers with each of the exhaust chambers having an aperture that opens towards a side on which the board is mounted;
- a sound absorbent material provided to at least a portion of at least one of the walls, the sound absorbent material being removably coupled to the table;
- and
- an air flow creating section configured and arranged to create an air flow within the exhaust chambers;
- the walls including a front wall having an exhaust aperture and a side wall extending in a direction approximately orthogonal to the front wall with the air flow creating section being configured and arranged to create the air flow in a direction approximately parallel to the side wall towards the front wall, and
- the sound absorbent material being provided at least to the side wall.
