Cutting Apparatus End Face Correction via Integrated Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cutting apparatus requires a time-consuming and labor-intensive end face correction process for the mount flange, involving frequent replacement of chuck tables and dedicated jigs, which increases the number of man-hours needed for correction.
Innovation Solution
Integration of an end face correction unit mounted on the processing feed unit's table moving base, which includes a holder for a polishing grinding stone and a positioning unit to easily contact and retract the grinding stone for correcting the mount flange's end face without obstructing the cutting operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated chuck table with a polishing grinding stone is used for end face correction, then the end face correction process can be performed, but the process becomes time-consuming and labor-intensive requiring replacement of chuck tables and dedicated jigs
Solution Approach 1:
The polishing grinding stone is integrated directly onto the chuck table, merging the workpiece holding function with the end face correction function. This eliminates the need for separate dedicated chuck tables and jigs, allowing end face correction to be performed in-situ without equipment replacement, thereby reducing man-hours and process time while maintaining correction capability
Solution Approach 2:
The chuck table is designed to perform its own end face correction function through the integrated polishing grinding stone. The system serves itself by enabling the chuck table to correct its own end face without requiring external dedicated correction equipment, thus eliminating the need for operator intervention to replace tools and reducing labor time
2Reliability
If a dedicated jig with polishing grinding stone is fastened to a dedicated chuck table, then end face correction can be performed, but the device complexity increases due to multiple dedicated components
Solution Approach 1:
The chuck table is designed with multi-functionality, serving both as the workpiece holding device and as the end face correction device through the integrated polishing grinding stone. This universal design eliminates the need for separate dedicated chuck tables and jigs, reducing device complexity while maintaining the end face correction function
Solution Approach 2:
The polishing grinding stone and chuck table are merged into a single integrated component. This combination reduces the total number of parts from multiple dedicated components (dedicated chuck table + dedicated jig + polishing stone) to a single multi-functional chuck table with integrated grinding capability, thereby simplifying the overall device structure

AI summary
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.
