Honing Tool With Unequal Guide Opening Pitches for Reduced Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing honing tools lack flexibility and stability, leading to suboptimal surface quality and increased vibration during machining, particularly in complex bore configurations.
Innovation Solution
A honing tool with double infeed and double expansion, featuring a tool body with 14 or more guide openings at unequal angular pitches, allowing for asymmetrical distribution of cutting groups and reduced vibration, enhancing surface quality and tool life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If guide openings are arranged at equal angular pitch, then manufacturing is simpler, but vibration increases and surface quality decreases
Solution Approach 1:
The patent applies asymmetry by arranging guide openings at unequal angular pitches instead of equal pitches. This asymmetric distribution prevents periodic vibrations that occur with symmetric arrangements, thereby improving surface quality and reducing machining vibrations while remaining manufacturable through standard machining processes.
2Device complexity
If cutting groups are symmetrically distributed, then tool structure is simpler, but adaptability to complex bore configurations is reduced
Solution Approach 1:
The patent implements dynamics by making the cutting group distribution adjustable rather than fixed. The cutting groups can be positioned at different angular locations and configured with varying numbers of cutting elements, allowing the tool to adapt to different bore configurations and machining requirements while maintaining a relatively simple overall structure.
3Manufacturing precision
If more guide openings are used, then cutting media coverage is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the guide openings into multiple groups, each associated with a specific cutting group. This segmentation allows for organized management of multiple guide openings and cutting elements, improving surface quality through comprehensive cutting media coverage while keeping the system manageable through structured organization rather than monolithic complexity.

AI summary
The invention relates to a honing tool (100) for machining the inner surface of a bore in a workpiece by means of at least one honing operation, comprising: a tool body (110) that defines a tool axis (112) and has a guide bore (115), which is coaxial to the tool axis, for receiving two adjusting elements which can be moved axially independently of each other, and a plurality of guide openings (160) which are distributed over the circumference of the tool body (110) and lead radially relative to the tool axis (112) from the guide bore (115) to an outer face of the tool body; a plurality of cutting means supports which each have a support section (152) that is wide in the circumferential direction and comprises an outer face for receiving cutting means, and have an adjusting section (158) that is narrower than the support section and has an inclined surface on the inner face facing away from the outer face for interacting with an associated inclined surface of one of the two adjusting elements. The adjusting sections of cutting means supports are each radially movably received in one of the guide openings. All the cutting means supports which can be adjusted via the first adjusting element form a first cutting group, and all the cutting means supports which can be adjusted via the second adjusting element form a second cutting group, wherein the tool body (110) has fourteen or more guide openings (160) which have an irregular angular division such that one or more of the guide openings has a different angular spacing (WA) from the directly adjacent guide openings in the circumferential direction.
