Solution Overview
Problem
The existing grinding processes for hard materials require multiple tools and stages, leading to lengthy machining times, increased costs, and inefficiencies due to tool changes and re-machining operations.
Innovation Solution
A single machining tool with multiple sections, each containing abrasive particles of varying diameters and concentrations, integrated into a single, detachable unit, allowing for simultaneous roughing and finishing operations without tool changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple grinding tools with different particle sizes are used for roughing and finishing stages, then manufacturing precision is improved, but productivity deteriorates due to frequent tool changes and lengthy machining times
Solution Approach 1:
The patent combines multiple grinding tools with different abrasive particle sizes into a single compound grinding tool. The tool body carries multiple abrasive bands or layers with progressively smaller particle sizes, allowing roughing, semi-finishing, and finishing operations to be performed sequentially with one tool, eliminating the need for tool changes between stages
Solution Approach 2:
The compound grinding tool is designed to perform multiple grinding functions simultaneously. Different sections of the tool body contain abrasive particles of varying sizes, enabling the single tool to execute roughing, semi-finishing, and finishing operations on workpieces of different materials and requirements without needing replacement
2Manufacturing precision
If multiple working positions are used to hold different tools, then manufacturing precision is improved through specialized tools, but device complexity increases due to additional working positions and tool change mechanisms
Solution Approach 1:
The invention merges multiple specialized grinding tools into a single compound tool structure. Instead of requiring separate working positions for roughing, semi-finishing, and finishing tools, all these functions are integrated into one tool that can be mounted at a single working position, simplifying the machining center configuration
3Manufacturing precision
If tool changes are performed between machining stages, then manufacturing precision is maintained through appropriate tool selection, but loss of time increases due to tool replacement operations
Solution Approach 1:
By integrating multiple abrasive bands with different particle sizes onto a single tool body, the invention eliminates the need for tool changes between roughing, semi-finishing, and finishing stages. The operator simply selects the appropriate abrasive band section on the compound tool for each operation, saving significant time compared to replacing entire tools

Function Achieved in This Case
This approach significantly reduces machining time and costs by enabling multiple grinding stages with a single tool, minimizing tool changes and energy wastage, and facilitating easy replacement of worn parts.
Implementation Method 1
a first tool with a grinding band containing, for example, large-diameter diamond particles in a bonding agent can be used; this is a roughing stage

AI summary
The machining tool (30) is used to grind a workpiece in a machining machine. The tool comprises at least a first machining portion having particles of a material harder than the workpiece material, the particles being arranged in a binder, and at least a second machining portion having particles of smaller diameter than the first machining portion, and of a material harder than the workpiece material, the particles of the second portion being arranged in a binder identical to that of the first portion or in a different binder.
