Solution Overview
Problem
Existing honing machines face challenges in efficiently machining bores aligned orthogonally in workpieces, such as cylinder crankcases, which require precise alignment and tight tolerances to minimize wear, friction, and emissions in internal combustion engines.
Innovation Solution
A honing machine with a rotary table and multiple workstations, including vertical and horizontal honing stations, allows for the machining of bores with axes oriented vertically or horizontally, enabling orthogonal machining without the need for intermediate reclamping or tool changes, and facilitates compact design with enhanced mechanical stability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single honing station is used, then the device complexity is reduced, but the productivity decreases due to the need for intermediate reclamping and tool changes
Solution Approach 1:
The honing machine is divided into multiple independent workstations (first vertical honing station, second vertical honing station, and horizontal honing station), each capable of performing specific honing operations. This segmentation allows different bores to be machined simultaneously at different stations, eliminating the need for intermediate reclamping and tool changes, thereby improving productivity while maintaining manageable complexity through modular design
Solution Approach 2:
Multiple honing stations with different orientations (vertical and horizontal) are combined into a single integrated machine structure sharing common components like the control unit and base. This merging allows orthogonal bores to be machined in one setup, improving productivity while the shared infrastructure prevents excessive complexity increase
2Productivity
If multiple workstations are added, then the productivity increases, but the installation space increases
Solution Approach 1:
The machine utilizes vertical space by implementing both vertical and horizontal honing stations within the same machine envelope. The vertical honing stations operate in the vertical plane while the horizontal honing station operates in the horizontal plane, effectively using three-dimensional space to accommodate multiple workstations without proportionally increasing the footprint area, thus improving productivity while controlling installation space
3Adaptability or versatility
If vertical and horizontal honing stations are combined, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The machine is designed with universal components that serve multiple functions: the control unit manages all workstations, the base supports all stations, and the tool holders can accommodate different honing tools. The vertical and horizontal honing stations share common structural elements and control systems, enabling the machine to handle various bore configurations (vertical and horizontal) with a unified system, thereby improving versatility while preventing excessive complexity through standardized multi-functional components

AI summary
The invention relates to a honing machine (100) for honing bores aligned orthogonally to one another in a workpiece (102), in particular for honing cylinder bores and a bearing track bore in a cylinder crankcase, comprising a machine base (110) and a round table (130) which is arranged on the machine base, can be rotated about a vertical round base axis (134), and has multiple workpiece receiving areas that are arranged in an offset manner relative to one another in the circumferential direction at a radial distance to the round table axis such that a workpiece received in a workpiece receiving area can be transported to different workstations (140, 150, 160, 170) of the honing machine one after the other by rotating the round table. At least one of the workstations is a vertical honing station (150, 170) which has at least one vertical honing unit (180) that has a honing spindle, said honing spindle being movable in a rotatable manner about a spindle axis, which is aligned parallel to the round table axis, and back and forth in the direction of the spindle axis. Furthermore, at least one of the workstations is a horizontal honing station (160) which has at least one horizontal honing unit (300) that has a honing spindle, said honing spindle being movable in a rotatable manner about a horizontal spindle axis (304) and back and forth in the direction of the spindle axis. The horizontal honing unit (300) is positioned or can positioned relative to the round table (130) such that the horizontal honing unit assumes a work position in which the horizontal spindle axis (304) is aligned radially to the round table axis (134).
