Abstract:
In the dicing machine, a flange cover with which the blade is covered is divided into two, and the first cover is openable. An interlock device is provided so that a blade attaching and detaching device cannot be attached when the first cover is at the closing position, the first cover cannot turn to the closing position when the blade attaching and detaching device is attached, and the processing of the work is not started when detected luminous energy of a blade breakage detector, which is attached to the first cover, is not reduced by a predetermined amount. Thus, the blade and the work are prevented from being damaged by processing the work without applying coolant, the mechanism of the dicing machine and the blade attaching and detaching device are prevented from being damaged by operating the dicing machine without detaching the blade attaching and detaching device, and the work is prevented from being unprocessed but sent out by operating the dicing machine without attaching the blade.
Abstract:
In the cutting solution supplying and controlling apparatus for a dicing machine, a flow rate adjusting device is provided in addition to a regulator as the pressure adjusting device. The flow rate adjusting device has a flow rate controller, which controls a proportional solenoid valve according to a signal applied from a flow rate sensor as a feedback signal. Thus, even if the pressure of the water supplied from the water supply equipment of the factory changes, the flow rates of the cutting solution and the coolant are maintained. Moreover, the flow rates can be easily adjusted according to the type of work to be processed.
Abstract:
The flange cover covering the blade is divided into two. The second cover is turnably connected to the first cover through a shaft parallel with the spindle of the blade, and the second cover is opened and closed in connection with vertical movement of the spindle. When the spindle is moved upward for replacing the blade, the second cover is automatically turned to the opening position, and L-shaped coolant jetting nozzles are moved away from positions below the blade to positions beside the blade. Thus, the blade can be easily replaced, and an automatic blade replacing system can be applied.
Abstract:
The dicing machine has a shielding plate movably arranged between a processing part and a microscope so as to check mist and spray produced from the processing part. The shielding plate can be moved back and forth between a shielding position and a retreated position, so that the shielding plate is positioned at the shielding position during processing of the work and at the retreated position when the operator replaces the old blade with a new one. Thus, even if the dicing machine has two spindles facing to each other, the shielding plate does not interfere with replacement of blades on the spindles.
