Abstract

The invention relates to the design of metal cutting tools. The purpose of the invention is to increase the ease of operation of the cutters. The milling cutter comprises a housing 1 and cutting plates 2 mounted on the holders 3. The holders are located in the slots of the housing with gaps between the lower surfaces of the 4 holders and the bottom 5 groins. By making the bottom of the grooves with a lift, the gap is smoothly reduced to the cutter axis until it contacts at point 6. The plates are secured with screws 7 and springs 8. To release the plates, it is enough to insert the lever 10 into the gap between the holders and the body slot opposite the direction of the spring action. 1 il. (L f

Description

one

The invention relates to the design of metal cutting tools.

The purpose of the invention is to increase the ease of operation of the cutter by facilitating the process of securing and unfastening the cutting inserts.

The drawing shows the design of the cutter.

The milling cutter comprises a housing 1 and a plate 2 mounted on the holders 3. The holders are mounted in the housing slots with gaps between the bottom surfaces of the 4 holders and the bottom 5 slots. The bottom of the grooves made with the rise in the direction of the axis of the cutter, which ensures a smooth reduction of the specified gap to the contact between the holders and the bottom of the grooves at the points 6 of the lower surfaces of the holders closest to the axis of the cutter. The holders are fastened with screws 7 and springs 8. The screws are screwed into the threaded holes of 9 holders perpendicular to their bottom surfaces.

To release the plate into the gap between the holder and the bottom of the groove, insert the lever 10 and press into

direction opposite to the spring action. In this case, the holder, resting at point 6, turns around and bears out the cutting insert. The spring-loaded pressing of the plates to the body reduces the risk of their breaks, when fastening and in operation.

Claims (1)

10 claims A milling cutter comprising a body and cutting plates mounted on holders located in the grooves of the core 15 with gaps between the lower surfaces of the holders and the bottom of the grooves and secured with spring-loaded screws, screwed into the threaded holes of the holders, perpendicular to their lower surfaces, characterized in that, in order to increase the ease of operation of the cutter, the bottom of the grooves is complete with a rise in the direction of the cutter axis, 25 ensures that in this direction there is a gradual decrease in the size of the gaps between them and the lower surfaces of the holders until they contact at the points of the lower surfaces of the holders closest to the axis of the milling cutter.
