(54) METHOD FOR MAKING ROUND SAWS

I

The invention relates to machine building, and can be used in the preparation of wood-turning saws.

There is a known method of preparing circular saws, which includes the steps of making a billet, quenching, tempering, grinding box surfaces, notching teeth, forging, and straightening.

The disadvantage of the known method of manufacture (circular saws is the formation of ciska plate after the first grinding of the teeth, which leads to the need for additional recutting (editing) of ciscs.

The purpose of the invention is to reduce the blade of the saw blade after the first grinding of the teeth and reduce the complexity of the dressing.

The goal is achieved by the fact that the notch of the teeth is made by sifing up the side surfaces of the disk.

With the specified sequence of operations in the process of grinding the side (face) surfaces of the disk, the

This is the most unfavorable layer of riveted metal formed by the nprf notch of the teeth. Therefore, after sharpening the eubic, the equilibrium of the stressed state of the disk is disturbed to a much lesser extent.

Example, It was made of 10 saws with a diameter of 500 mm, a thickness of 2.2 mm in the usual and new technology. The sharpening of the teeth was carried out under the same conditions on a single machine. The average tare value of saws of the first group increased from 0.25 to 0.69 mm (2.8 times), and saws of the second group increased from 0.31 to 0.38 mm (1.2 times). Operation saws first

$ 1 group without additional editing was impossible. Saws of the second group demanded insignificant dressing and 30% could be operated without performing it,

The use of the proposed method of manufacturing circular saws ensures the reduction of labor-intensive straightening after sharpening the teeth, the possibility of supplying saws
