The machine is specifically designed for the watchmaking and precision mechanics industries. It consists of two main parts:
- Cross slides with polishing arm and wooden polishing disc
- Support spindle block with carbide pads
The polishing spindle is made of hardened and ground steel. To balance the weight of the polishing arm, the spring tension is adjusted by moving the hook on the locking mechanism. The cross slides with polishing arm are moved using two knurled-head screws, which facilitates positioning the polishing disc relative to the tooth recesses.
A limit screw is used to set the immersion depth of the polishing arm. After precise adjustment, the screw is secured with a nut. The same screw also regulates the wear of the polishing disc.
Exact alignment of the spindle to the axis of the notches in the carbide support disc is ensured when the pins are correctly seated in their designated holes. After removing the pins, the spindle can also be tilted for bevel gear polishing. The spindle with workpiece support is precisely aligned to the pinion axis using a pin and fixed with a lever.
Both carbide pads have V-shaped grooves around the circumference in which the workpiece is placed. The two discs are connected by a pin, ensuring the grooves are always correctly aligned. The distance between the two supports is adjusted using a screw.
The wooden polishing disc must first be turned before polishing. Polishing paste is applied to the circumference of the disc. The disc has a slot that is widened with a small wedge so that each rotation engages the next tooth.
