not only outside the machine, but also on the machine. The cutting holder includes a housing 1 with a groove iod cutter 2. Screws 3, 4 and 5 are installed to adjust the position of the cutter in the housing. To fix the cutter, use gaskets 7 installed on the free ends fixed in the upper part of the U-shaped spring housing 6. Gaskets 7, the cutter is pressed against the support surface, and when the holder is installed in the tool holder, a screw 9 is clamped through them. With loosened screws 9 with screws 3. 4 and 5, the tool is adjusted with respect to the coordinates of the machine, 1 slug.

The invention relates to machine tools, in particular to the auxiliary

tool mounting accessories

on metal-cutting lathes CNC group.

The purpose of the invention is the expansion of the technological capabilities of the holder by setting the cutter to the size of the processing, not only outside the machine, but also on the machine.

FIG. 1 schematically shows the proposed holder, general view; in fig. 2 - ^{1 is} the same, top view; in fig. 3 - the same, left view; Fig 4 installation of the holder in the tool holder.

The tool holder contains a body I with a groove for cutter 2. In the lower support part of the body 1, holes are made for the adjusting screws 3 5. U-shaped spring elements 6 are fixed to the upper part of the body I with gaskets installed at their free ends 7. Cutter 2 is adjusted to the size in the tool holder outside the machine on an optical device or machine using a special tool (not shown) with the help of adjusting screws 3 5. U-shaped spring elements 6 serve for preliminary fixation of the cutter 2 in the case I. Gaskets 7 optional We need to fasten the holder with the carved in the tool holder 8 so that the tool does not move. After setting and pre-fixing the cutter 2, the holder with the cutter is installed in the tool holder 8 and clamped with screws 9. The height of the centers of the machine tool is made by means of a screw 10.

Elements of the regulation of the holder are as follows.

The screw 3 is in contact with the end of the tool holder 8, the screws 4 and 5 are in contact with the groove of the tool holder 8 in the vertical plane. Pre-fixation ensures sufficient reliability of fixing the cutter with the possibility of adjusting its position when adjusting to the coordinates "x" and "ζ". The reliability of fixation is ensured by the selection of the appropriate section of the springs.

The proposed holder is designed to adjust the cutter to the machining size both on the machine and outside the machine, because the tool coordinates are shifted relative to the machine coordinates when the entire tool holder is brought to the zero point when setting up the machine, i.e. "Ζ".
