The “Collet chuck jig” is a jig that clamps a workpiece by expanding / contracting the collet. Stable clamping is realized by setting the clamping force according to the body shape and cutting resistance according to the cutter’s machining trajectory, and by utilizing CAE analysis. Furthermore, various quick-change mechanisms enable easy stage changes to accommodate a wide variety of workpieces. This contributes to “stable runout accuracy” and “reduction of man-hours” required for step changes.
Ensuring maximum rigidity according to the cutter trajectory
Optimal retraction mechanism:
Setting clamp force according to the cutting force
This is the point!
Jig design with consideration of product changeover
Excellent!
Quick change of parts Complete the changeover by replacing the reference seat and collet
Reference seat replacement
Quick change by key hole design
Collet replacement
Quick change by unique mounting mechanism
Approx. 50% less setup time when compared with conventional products!
Quick change of chuck The chuck can be changed with one operating screw
Chuck replacement
Quick change mechanism allows easy positioning and fixing
Easy changeover
Replacing only the chuck. Also supports changeover of inner/outer diameter chuck type.
Approx. 67% less setup time when compared with conventional products!
Development / product concept
“Current status and challenges”
Electric vehicles require high-precision transmission gears so that the motor can be driven with high efficiency. For this reason, precision machining is essential, especially in the gear cutting and gear grinding processes.
In addition, with the increasing need for multiple-product production, it is necessary to change fixture stages easily and quickly.
“Development points”
With the “collet chuck jig”, a high-precision and stable work chuck has been developed with an optimal clamping mechanism, body shape, and clamping force.
Furthermore, the quick-change mechanism allows for easy change-over in multi-product production, contributing to a reduction in man-hours.
