AI Technical Summary

Technical Problem

Conventional turning methods fail to achieve high machining accuracy due to vibrations, bending, and inadequate support, and existing reamers are either dedicated to specific diameters or lack precision along the entire depth of the bore, with adjustable tools facing challenges in supporting imperfect alignments and blade replacement.

Method used

A reamer with multiple guides arranged at an angle around the central axis, a movable blade holder, and an adjusting screw system that allows for simultaneous movement of guides and blade positioning, enabling machining of various diameters and quick blade replacement, along with a floating head assembly that reduces weight for improved accuracy.

Benefits of technology

The solution provides high machining accuracy, allows for machining of different diameters, and facilitates quick blade replacement, while the floating head assembly enhances precision by reducing machining errors and allowing coolant supply for improved cutting performance.

Abstract

The invention relates to a reamer and to a reamer and floating head assembly. The task of the invention is to provide a reamer that will provide for high machining accuracy, will be adjustable for machining workpieces having different diameters and will allow for quick restoration or replacement of blades and guides. A reamer (1; 101) comprises a head (2; 102), at least three guides (3; 103), each consisting of a guide part (3 a; 103 a), movably arranged in the head, and a pointed part (3b; 103b), the guides being arranged at an angle φ with respect to the central axis of the head, and wherein part of the surface of the pointed part of the respective guide, which is intended to come in contact with the workpiece, is arranged at the same angle φ with respect to the central axis of the respective guide so that part of the surface of the pointed part of the respective guide, which is intended to come in contact with the workpiece, is arranged parallel to the central axis of the head, a blade holder (4; 104), an adjusting screw (5; 105) of the guides, elements (3c, 5a, 5b, 11, 12; 103c, 111) for transferring the translational movement of the adjusting screw (5; 105) of the guides to the guides and the blade holder, and a blade (6; 106) for machining the workpiece.
