Solution Overview
Problem
Conventional machine tools face challenges with frequent maintenance needs and high manufacturing costs due to the easy entry of waste and cutting fluid into the Y-axis guide and feed mechanisms, and suffer from deflection and deformation issues affecting precision machining.
Innovation Solution
The machine tool design features a table enclosed by three sidewalls, with the first saddle and spindle head positioned above the table, reducing waste and fluid entry into guide and feed mechanisms, and includes a swivelable table for efficient waste removal and tool/pallet changing devices to minimize interference with operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the Y-axis guide mechanism and feed mechanism are disposed below the top of the table, then the table can be supported and moved efficiently, but waste and cutting fluid easily enter the mechanisms causing frequent maintenance and high manufacturing costs
Solution Approach 1:
The patent repositions the Y-axis guide mechanism and feed mechanism from below the table top to above the table top, changing the spatial dimension of component placement. This dimensional change allows the mechanisms to be positioned in a region less exposed to waste and cutting fluid, thereby reducing contamination while maintaining table movement functionality.
2Device complexity
If the saddle and spindle head are disposed to protrude from the front of the machine tool, then the structure is simplified, but deflection and deformation occur affecting machining precision
Solution Approach 1:
Instead of allowing the saddle and spindle head to protrude forward from the machine tool front, the patent inverts the arrangement by positioning these components retracted within the machine tool body. This inversion eliminates the protruding structure that caused deflection and deformation, thereby improving machining precision while maintaining operational functionality.
3Reliability
If multiple covers are disposed to prevent waste and cutting fluid from entering the guide and feed mechanisms, then the mechanisms are protected, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the protective cover functions into a more integrated structure. Instead of separate covers for different axes and mechanisms, the design combines protection features into unified cover structures that serve multiple protective functions simultaneously, thereby reducing overall device complexity while maintaining comprehensive protection against waste and cutting fluid entry.

AI summary
Machine tool simplifying maintenance, reducing manufacturing costs, and enabling high precision machining. The machine tool is equipped with: a bed furnished with a rectangular base, right and left sidewalls provided standing either side of the base, and a rear sidewall provided standing along the back of the base; a table disposed in the space surrounded by the three sidewalls; a first saddle shaped in the form of a rectangular frame shape, provided free to shift back and forth supported on the tops of the left and right sidewalls; a second saddle penetrated by a perpendicular through-hole and arranged free to shift sideways inside the first saddle frame; and a spindle head arranged free to shift perpendicularly inside the through-hole in the second saddle; and a main spindle arranged over the table and supported by the spindle head free to rotate centered on its axis.
