SU383590A1 - DISK SAW FOR CUTTING - Google Patents

Description

This invention relates to IK devices for the machining of wood, plywood.

The known devices do not provide the required quality of the surface treatment of the part.

The purpose of the invention is to increase labor productivity and quality of surface treatment of the part.

This is achieved by the fact that the angle of oblique sharpening on the front and rear edges is made sharp (65 65 ° -85 °) from the side of the workpiece surface of all the teeth.

FIG. 1 shows a single-sided circular saw for longitudinal cutting; in fig. 2 - saw tooth in Propyl; in fig. 3 is a section along LL in FIG. 2; pas figs. 4 — one-sided saw for transverse fine trimming; and FIG. 5 - saw tooth in the saw; in fig. 6 - razrbz on bb in fig. five; in fig. 7-sided disc saw for longitudinal-transverse cutting; in FIG. 8 - saw tooth B propyl; in fig. 9 is a section along the line B – B of FIG. eight.

The disk saw of longitudinal trimming has a front angle of sharpening of the tooth U °. The circular saw for transverse cutting Y 0 °; and for circular saws for longitudinal-transverse cutting 10 ° 7 - ° For single-sided saws of great angle

sharpening the front face fp, and the angle of the oblique sharpening of the rear face fz1 of all teeth from the side of the workpiece surface is positive; Fp, and fz, 90 °, and the magnitude of the angles fp, and fz, from the descent side is negative: fp, and fz, 90 °.

The number of teeth machining each of the two surfaces of the saw at the saw is equal to niMeMy chi; the case of the teeth of the saw.

In the well-known hard metal, saws FZ, and FP, FP,; 90 °, but the number of s-kill, processing each of the surfaces of the cut. equal to half the number of all saw teeth.

When one-sided carbide circular saws are used, the number of teeth machining the surface of the part when finishing trimming is twice as much as when using the known carbide saws and, therefore, the feed per tooth is half that, which makes it possible to significantly improve the quality of processing.

Subject invention

.Disc saw for finishing trimming, for example, wooden parts, includes, and Diok with a landing hole. M., Cutting teeth, equipped, with hard alloy plates, having a slanting front and

Grandfather Grandee, Expecting {o. so that, with increasing performance and quality of the surface treatment of the part, the angle of oblique sharpening on the front and rear edges is sharp (оли 65 ° -85 °) from the side of the workpiece surface for all saw teeth.
