- Patented Product: "Push Rod"
When machine processing, the work item is grasped by the chucking structure, and inside the chucking structure is a jig that cleans the work item.
With normal jigs shavings can accumulate inside the chuck following prolonged use, and this creates a problem in that it can damage the product.
In response to this problem, we developed the "push rod," a product that through its special structure increases its ability to expel shavings.
