Machine Tool Bed Opening and Rib Layout for Chip Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine tools with beds struggle to efficiently collect chips generated during machining, while maintaining sufficient rigidity, as existing designs do not effectively address chip accumulation and discharge within the processing area.
Innovation Solution
A machine tool design featuring a bed with a vertically penetrating opening portion and a rib portion, allowing for efficient chip discharge from the upper to the lower side, combined with guide portions and mounting surfaces to ensure table movement and rigidity, and an automatic pallet changer for enhanced chip collection during pallet changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bed is provided without opening portions, then bed rigidity is maintained, but chip discharge performance deteriorates
Solution Approach 1:
The bed is segmented by introducing opening portions that divide the bed structure into regions, allowing chips to be discharged from the upper side to the lower side while maintaining structural integrity through strategically placed ribs
Solution Approach 2:
The opening portions extend in the vertical direction (third axial direction), creating a three-dimensional chip discharge path that allows chips to be evacuated from the processing area through the bed thickness, adding a vertical dimension to chip removal
2Productivity
If opening portions are added to the bed for chip discharge, then chip collection efficiency is improved, but bed rigidity deteriorates
Solution Approach 1:
The bed structure is modified locally by adding rib portions at specific locations within the opening portions, creating localized structural reinforcements that maintain rigidity only where needed while preserving chip discharge pathways in other areas
Solution Approach 2:
The opening portions are positioned asymmetrically between the first and second guide mounting portions, with rib portions strategically placed to provide uneven reinforcement that optimizes both rigidity and chip discharge performance
3Object-generated harmful factors
If the opening portion length in the second axial direction is increased, then chip discharge capability is improved, but the table movement space is reduced
Solution Approach 1:
The opening portions extend primarily in the vertical direction (third axial direction) rather than horizontally, creating a vertical chip discharge path that does not encroach on the horizontal table movement space while still providing effective chip evacuation

AI summary
A machine tool includes a table, a first guide portion and a second guide portion that guide the table in the Z-axis direction and are arranged apart from each other in an X-axis direction, and a bed that includes a first guide mounting portion and a second guide mounting portion on which the first guide portion and the second guide portion are mounted respectively, and is provided with an opening portion which is located between the first guide mounting portion and the second guide mounting portion and penetrates in a Y-axis direction. The first guide mounting portion and the second guide mounting portion are respectively provided with a first facing surface and a second facing surface which face each other across the opening portion. The bed further includes a rib portion which is located in the opening portion and connected to the first facing surface and the second facing surface.
