Dual Gang Tool Post Layout for Versatile Multi-Axis Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools lack the capability to perform a wide variety of machining operations with a simple configuration, particularly in arranging tools in a Y-axis direction parallel to each other.
Innovation Solution
The machine tool design includes a turning tool base on one gang tool post and an end surface tool base on the opposing gang tool post, with both tool bases capable of independent movement in the X, Y, and Z directions, allowing for multiple machining operations with tools arranged in a tooth comb shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tools are arranged parallel to each other in the Y-axis direction on gang tool posts, then the machine tool can perform multiple machining operations, but the configuration becomes more complex
Solution Approach 1:
The patent applies multi-functionality by equipping gang tool posts with both turning tool bases and end surface tool bases, allowing the same tool post structure to perform multiple machining operations (turning, facing, drilling, etc.) that would traditionally require separate dedicated tool posts, thereby increasing versatility without proportionally increasing complexity
Solution Approach 2:
The patent merges multiple tool base functions into a single gang tool post structure. By integrating both turning tool bases (for lateral tool mounting) and end surface tool bases (for axial tool mounting) on the same gang tool post, the design combines previously separate functional elements into one unified structure, achieving space efficiency and operational versatility
2Adaptability or versatility
If a turning tool base is integrated on the gang tool post, then the machine tool can perform turning operations, but the structural complexity increases
Solution Approach 1:
The patent segments the tool base functionality into distinct modular components - turning tool bases and end surface tool bases - that can be independently configured and mounted on gang tool posts. This segmentation allows the machine tool to gain turning capabilities through optional modular addition rather than requiring a completely reconfigured complex structure
Solution Approach 2:
The patent utilizes spatial arrangement by positioning turning tool bases and end surface tool bases at different orientations and locations on the gang tool post structure. This dimensional arrangement allows multiple tool bases to coexist without excessive structural complexity, as they occupy different spatial dimensions and can be accessed independently

AI summary
To provide a machine tool that includes tool posts each having a tooth comb shape and can perform a wide variety of machining in multiple manners with a simple configuration. A machine tool includes a main spindle (7) movably supported in an axial direction, and two gang tool posts (27, 56) disposed opposed to each other with an axis of the main spindle (7) located therebetween. Each of the two gang tool posts is supported movably in X and Y directions that are perpendicular to the axial direction of the main spindle. Each of the two gang tool posts is provided with tools (19, 47) arranged parallel to each other in the Y direction. One of the two gang tool posts (56) is movably disposed in a Z direction that is a same direction as the axial direction of the main spindle (7). Any one of the two gang tool posts (27) is integrally provided with a turning tool base (34) that turnably supports tools (31) about a Y-axis along the Y direction.
