AI Technical Summary

Problems solved by technology

These elastomeric rings are rather soft, which results in a low spring constant and low damping frequency for a given mass of the damper mass, thereby limiting the range of possible shapes and sizes of tool bodies and machining tools that can be properly damped
In addition, elastomeric materials may not be able to withstand the high temperatures that may occur during the particular processing operation desired, so that excessive cooling will be required or the efficiency of the processing operation must be reduced to keep the temperature down

Embodiment Construction

[0024] figure 1 Shown is a machining tool 1 for turning which, in addition to a tool body 2 according to an embodiment of the invention, has a component 3 fastened at the end 5 of the tool body, which has a Cutting inserts in the form of turning 4. The tool body can also be used in machining tools for other types of machining, such as milling, drilling or boring, after which a corresponding member with at least one cutting edge for chip removal machining is fixed to the tool The end 5 of the body.

[0025] The tool body comprises a damping device 6 for damping vibrations in the machining tool caused by the machining operation and is arranged in an inner space 7 of the tool body defined by a housing 8 (see image 3 )middle. The damper device comprises a damper mass 9 of high-density material, such as lead, having a cylindrical shape with an axial through hole 10 . The inner space 7 contains a damping fluid, such as oil, in an annular cavity 22 which radially separates the d...

Abstract

A tool body (2) includes a damping apparatus for damping vibrations in a machining tool having besides the tool body a member with at least one cutting edge to be secured to the tool body. The dampingapparatus is arranged in an internal room (7) of the tool body and comprises a damper mass body (9) with an axial bore (10) and a central tube (11) extending through the bore and which is rigidly secured to the damper mass body inside the through bore. A central tube (11) is also at both ends (12, 13) thereof rigidly connected to a tool body fixed part (14, 15) and the central tube is made of a material with a spring property allowing the damper mass body (9) to oscillate in the internal room (7) perpendicularly to the longitudinal extension of the central tube.

Description

technical field [0001] The invention relates to a tool body according to the preamble of claim 1 and to a machining tool having such a tool body comprising damping means for damping vibrations in the machining tool. [0002] The invention is not limited to tool bodies and machining tools for any particular type of machining, and the tool body may, for example, have a member fixed thereto with a cutting edge in the form of a cutting insert for turning, milling, , Drilling or boring to remove chips from the workpiece. Thus, the tool body may be designed to receive a cutting head comprising a cutting edge or a seat for a cutting insert. Includes rotating and non-rotating machining tools. Nor is the invention limited to such machining tools of any size, but these may for example have a diameter of 500 mm and a length of 6 meters, or be as small as having a diameter of only 10 mm. [0003] The tool body is provided with damping means for damping radial and tangential forces exer...
