Description

FIG. one

The invention relates to metal cutting and can be used in marine engineering and shipbuilding.

The purpose of the invention is to increase the productivity and accuracy of processing by telling the cutting elements of the tool only radial feed.

Figure 1 shows a tool for implementing the proposed method; figure 2 - section aa in figure 1.

A multi-blade tool 1 with radially adjustable cutting elements 2 is inserted into the pre-machined hole. After the rotation has been reported to the tool, radial feeding of its cutting elements within 0.0005-0.0030 mm / rev is made at a cutting speed of 1-3 m / min. .

The treatment is carried out with a build-up with a radius of rounding less than 0.0005-0.0030 mm, formed on the cutting edges of the tool under these cutting conditions, the absence of a longitudinal tool feed, the use of coolant that does not prevent the formation of growth (kerosene, mineral and organic oils).

The use of cutting speeds within 1-3 m / min prevents self-oscillations in the AIDS system, which, at high cutting speeds, are formed due to the large length of the cutting edges and the removal of thinner chips.

Fo rmu l and z obre ts A method of machining holes with a multi-blade tool with radially adjustable cutting elements, which is reported to rotate, characterized in that, with the aim of increasing accuracy and productivity, use a tool with cutting elements whose length is equal to or greater than the generatrix of the hole being machined, and give them a radial feed in the limit of ax 0.0005-0.0030 mm / rev at a cutting speed of 1-3 m / min.

Claims (1)

Claim A method of processing holes with a multi-blade tool with radially adjustable cutting elements 15, which is informed by rotation, which differs with the idea that, in order to increase accuracy and productivity, a tool with cutting elements is used, the length of which is equal to or 20 longer than the generatrix of the hole being machined, and inform them radial feed in the range of 0.0005-0.0030 mm / rev at a cutting speed in the range of 1-3 m / min.
