Honing Tool Play Compensation Device for Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Honing tools experience wear-related issues such as one-sided cutting surface wear and honing stones becoming stuck or falling out due to increased play between the honing stone and the honing stone receiving opening over time, leading to suboptimal machining results and reduced tool life.
Innovation Solution
A play compensation device with an elastically deformable support element is implemented between the honing stone and the honing stone receiving opening, which maintains a pressing force to compensate for wear-induced changes in tolerances, ensuring reliable retention and alignment of the honing stone, and also functions as a retraction device to facilitate easy tool removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding fit is achieved by precisely machining the boundary surfaces of the honing stone mounting opening and the corresponding side surfaces of the honing stone, then the honing stone can be inserted by hand and held by static friction forces, but wear-related issues such as one-sided cutting surface wear and honing stones becoming stuck or falling out occur after longer periods of use
Solution Approach 1:
A play compensation device with an elastically deformable support element is arranged between the honing stone and the honing stone receiving opening. This support element compensates for wear-induced play before the honing stone becomes stuck or falls out, maintaining reliable retention throughout the service life of the honing tool.
2Manufacturing precision
If the dimensions of the honing stone receiving opening and the honing stone are matched to achieve a sliding fit, then the honing stone is radially movable and accommodated essentially without play, but increased play develops over time due to wear
Solution Approach 1:
The play compensation device transforms the static sliding fit into a dynamic system. The elastically deformable support element automatically adjusts to compensate for wear-induced dimensional changes, maintaining stable dimensional relationships between the honing stone and receiving opening throughout the service life.
3Reliability
If last stop bushings are used to prevent honing stones from falling out, then stones are retained during tool removal, but the device complexity increases and does not address one-sided wear
Solution Approach 1:
The play compensation device combines multiple functions into a single integrated component: it compensates for wear-induced play, prevents one-sided wear by maintaining proper alignment, and prevents honing stones from falling out during tool removal. This eliminates the need for separate last stop bushings and other retention devices.
4Ease of operation
If honing stones are held by static friction forces between side surfaces, then insertion is easy, but the friction forces are insufficient to prevent stones from getting stuck or falling out after wear
Solution Approach 1:
The play compensation device changes the retention mechanism from relying solely on static friction forces to using elastic restoring forces. The elastically deformable support element provides continuous pressing force that compensates for wear, maintaining sufficient retention force throughout the service life while preserving easy insertion.

AI summary
A honing tool has a tubular tool body (110) which is fixed at one end section in a tool shank (120) and has a cutting area at the opposite end section with at least one honing stone receiving opening (140) extending from the inside of the tool body to the outside for receiving a honing stone (150). The dimensions of the honing stone receiving opening and the honing stone are matched such that the honing stone is radially movable and is received with essentially no play between the limiting surfaces of the honing stone receiving opening in the circumferential direction of the tool body.A clearance compensation device (160) is provided between the honing stone and the honing stone receiving opening. This device has at least one elastically deformable support element (165) which, in the installed state of the honing stone, bears against a side surface (153) of the honing stone (150) on one side and against a boundary surface (143) of the honing stone receiving opening opposite the side surface, exerting a pressure force. For this purpose, the honing stone has a recess (162) on a side surface (153) in a guide section (155) designed to interact with the honing stone receiving opening (140). An elastically deformable support element (165) is arranged in this recess. In the unloaded state, this support element projects beyond the side surface (153) of the honing stone and, in the installed state of the honing stone, partially deforms and bears against a boundary surface (143) of the honing stone receiving opening opposite the side surface, exerting a pressure force.
