Cutting machine
A cutting machine comprising a chuck table for holding a workpiece, which is arranged such that it can move along a guide rail extending in a predetermined direction, a gate-like support frame that is arranged straddling the guide rail and has an opening for allowing the movement of the chuck table, an alignment means arranged on one flank of the gate-like support frame, and a cutting means arranged on the other flank of the gate-like support frame, wherein the cutting means is composed of an indexing-feed base arranged on the other flank of the gate-like support frame such that it can move in a direction perpendicular to the guide rail, a cutting-in feed base arranged on the indexing-feed base such that it can move in a direction perpendicular to the holding surface of the chuck table, and a spindle unit that is mounted on the cutting-in feed base and has a cutting blade, the spindle unit being arranged on the alignment means side through the opening of the gate-like support frame.
1. A cutting machine comprising a guide rail extending in a predetermined direction, a chuck table, which is arranged such that it can move along the guide rail, and has a holding surface for holding a workpiece, a cutting feed mechanism for cutting-feeding the chuck table along the guide rail, a support frame that is arranged straddling the guide rail and has an opening for allowing the movement of the chuck table, an alignment means mounted on one lateral surface of the support frame such that it can move in a direction perpendicular to the guide rail, and a cutting means for cutting the workpiece held on the chuck table, which is mounted on another lateral surface of the support frame such that it can move in a direction perpendicular to the guide rail, wherein
the cutting means is composed of an indexing-feed base arranged on the other lateral surface of the support frame such that it can move in a direction perpendicular to the guide rail, a cutting-in feed base arranged on the indexing-feed base such that it can move in a direction perpendicular to the holding surface of the chuck table, and a spindle unit that is mounted on the cutting-in feed base and has a cutting blade, the spindle unit being arranged on a side of the alignment means side through the opening of the support frame.
2. The cutting machine according to claim 1 , wherein the cutting-in feed base has a mounting portion that projects toward the side of the alignment means from the other side of the support frame through the opening, and the spindle unit is mounted on the mounting portion.
3. The cutting machine according to claim 1 , wherein the guide rail consists of a first guide rail and a second guide rail, which are arranged in parallel to each other, and the chuck table consists of a first chuck table and a second chuck table, which can move along the first guide rail and the second guide rail, respectively.
4. The cutting machine according to claim 3 , wherein the cutting means consists of a first cutting means and a second cutting means, and the cutting blade of the first cutting means and the cutting blade of the second cutting means are opposed to each other.
5. The cutting machine according to claim 3 , wherein the alignment means consists of a first alignment means for picking up an image of a workpiece held on the first chuck table to detect the area to be cut and a second alignment means for picking up an image of a workpiece held on the second chuck table to detect the area to be cut.
6. The cutting machine according to claim 1 , wherein the support frame is composed of a first pillar portion and a second pillar portion, which are arranged on both sides of the guide rail and a support portion connecting both upper ends of the first and second pillar portions, the alignment means and the cutting means are mounted onto the support portion, and an opening for allowing the movement of the spindle unit of the cutting means is provided in the first pillar portion and the second pillar portion.
7. The cutting machine according to claim 1 , wherein the operation position of an operator is formed in front of the alignment means, and an operation panel is arranged facing the operator.
