Processing multiple types of flywheel signal teeth with CNC milling machine

Modern engine components are becoming more diverse, and with the popularity of EFI engines, flywheels basically have signal teeth. The shape of the signal teeth is various, the traditional gear hobbing machine can not meet the processing requirements, and can not adapt to the multi-variety, small batch production mode, so now CNC milling teeth are getting more and more applications. This paper mainly introduces the characteristics and application methods of CNC milling.

1. CNC milling hardware

CNC milling equipment: CNC milling machine or machining center, indexing head (see Figure 1a); CNC milling cutter: three-sided milling cutter (see Figure 1b).

2. Several flywheel signal teeth suitable for machining with CNC milling

(1) Large horsepower flywheel. Features 58 narrow signal teeth and 1 wide signal tooth (see Figure 2). Since the teeth are not equally divided, they cannot be machined with a hobbing machine. By milling the teeth with a CNC milling machine, it is possible to machine any number of signal teeth in position and width.

These beads are coated with a special coating materials, during the manufacture of the glass beads, which will improve the characteristics of moisture-proof and adhesion of glass bead. In the way, the life cycle of the glass beads can be prolonged and this enhances the beads reflectivity in a rainy night. These beads are usually used in white or yellow line-construction of highway.
