This method for creating screw holes involves using a tap to form internal threads into pilot holes drilled with a drill. It allows for the rapid processing of numerous high-precision screw holes and is suitable for products requiring screw fastening.

This is a manufacturing method that applies pressure to a metal material and uses a rolling die to form the shape of screws and gears. Because it forms the material without cutting, it reduces material waste, improves strength, and enables mass production of high-precision products.

This machining method uses numerical control (NC) devices to precisely cut metals and resins. Because the movement of the tool is controlled by a program, it can reproduce complex shapes with high precision, making it suitable for high-mix, low-volume production.
