A cutting apparatus includes a chuck table for holding a workpiece thereon, a cutting unit for cutting the workpiece held on the chuck table with a cutting blade secured in place on a distal-end portion of a spindle by a mount flange mounted on the distal-end portion of the spindle, an indexing feed unit for moving the cutting unit in indexing feed directions parallel to axial directions of the spindle, a processing feed unit for moving the chuck table in processing feed directions perpendicular to the indexing feed directions, and an end face correction unit for correcting an end face of the mount flange that supports the cutting blade in contact therewith. The processing feed unit includes a table moving base that supports the chuck table thereon and an actuating mechanism for moving the table moving base. The end face correction unit is fixedly mounted on the table moving base.

A setup platform is provided for a grinder including a cutoff wheel. The setup platform includes an upper planar surface including a first edge, which may be shaped similar to the grinder housing, the first edge including a slot therein for receiving the cutoff wheel. An anchor bar is mounted horizontally to the grinder housing, and a post extending from a lower surface of the setup platform is slidable on the anchor bar such that the setup platform is slidable relative to the anchor bar to removably mount the setup platform to the grinder such that the first edge is disposed adjacent the grinder housing and the cutoff wheel is received in the slot.

A cutting apparatus is provided with a cutting unit. The cutting unit includes a spindle on which a cutting blade is mounted for rotation, a spindle housing that rotatably supports the spindle, a blade cover that is attached to the spindle housing and covers the cutting blade, a cutting water supply nozzle that supplies cutting water to the cutting blade, and a blade monitor that has an end face configured to monitor a cutting edge of the cutting blade. The end face of the blade monitor has a recessed portion to which rinsing water is supplied to rinse the end face.

A dressing board having, on a surface, a two-dimensional code including information relating to properties of the dressing board and a barcode including identification information associated with the information relating to the properties is provided. Furthermore, there is provided a cutting apparatus including a determining part that determines whether or not the properties of the dressing board read out from an information registration part based on the identification information match the kind of dressing board suitable for dressing of a cutting blade.

A processing apparatus includes a chuck table for holding a plate-like workpiece under suction. A suction unit is connected to the chuck table, and a processing unit is configured to process the workpiece while supplying processing water to the workpiece. The suction unit includes a first suction source, a first pipe providing fluid communication between the first suction source and the chuck table, a separator arranged in the first pipe, for separating a gas and a liquid drawn in from the chuck table, and a water discharging unit configured to discharge the liquid separated by the separator. The water discharging unit includes a second suction source, a second pipe providing fluid communication between the second suction source and a water discharge port of the separator, and a check valve arranged in the second pipe, for preventing a fluid from flowing from the second suction source to the separator.

The present disclosure provides an automatic chuck apparatus comprising a mechanical chuck, a mechanical chuck mounting bracket, a hydraulic motor, a lifting mechanism, a chuck key and a lifting cylinder. The mechanical chuck is mounted above the mechanical chuck mounting bracket. The hydraulic motor, the lifting mechanism and the lifting cylinder are mounted below the mechanical chuck mounting bracket. The hydraulic motor is configured to control the rotation of the chuck key, the lifting cylinder is configured to drive the chuck key to ascend or descend through the lifting mechanism, thereby the mechanical chuck is locked or loosened by the chuck key. The present disclosure further provides a grinding wheel cutting apparatus and a cutting method. In the present disclosure, the locking of the chuck is automatically controlled, thereby improving the working efficiency and ensuring sufficient locking force of the chuck.

A cutting apparatus includes a cutting unit including a spindle as a rotational shaft and a mount flange for mounting a cutting blade thereon, the mount flange being fixed to a distal end of the spindle, a support unit for supporting a cutting blade housed in a blade case, the support unit including a blade case support for supporting the blade case for housing the cutting blade therein, a changing mechanism for dismounting a cutting blade that has been mounted on the mount flange from the mount flange and mounting the cutting blade that has been supported on the support unit on the mount flange, and a moving mechanism for moving the changing mechanism between a changing position, a blade transfer position, and a retracted position.
