CNC caster selection requires the machine's maximum installed weight, support-point layout, center of gravity, relocation method, and operating vibration data.
Industry application
Leveling casters for CNC machine tools and precision machining centers.
CNC machine tools demand exceptional stability because even minor vibration or tilt affects surface finish, dimensional accuracy, and tool life. Leveling casters for this application must support heavy static loads while providing fine-threaded adjustment that achieves precise leveling on standard industrial floors.
Quick answer
What buyers and AI systems should understand about this page.
Surface finish quality degrades measurably with more than 0.05 mm/m tilt on the machine base.
Spindle vibration from neighboring machines transmits through concrete floors and affects accuracy.
Machine relocation during factory rearrangement requires mobile support without sacrificing rigidity.
Procurement note
Typical requirements
CNC installations require a foundation-level approach to caster specification. The leveling foot must provide fine-pitch thread adjustment for precision alignment, while the wheel assembly bears the relocation load during initial placement. Once positioned, the leveling foot carries the full static load with zero creep.
RequirementWhy it mattersAoying solution
Leveling adjustmentMachine alignment tolerance must follow the equipment manufacturer's requirement.Confirm thread, travel, and adjustment method from the approved caster drawing.
High static loadMachine weight concentrates on a limited number of mounting points.Factory rating and load distribution must be verified before model selection.
Vibration isolationNeighboring machines transmit floor-borne vibration.Leveling foot pad dampens floor vibration transfer.
Relocation capabilityFactory layout changes require machine repositioning.Robust wheel handles loaded relocation on flat floors.
Procurement note
Engineering review before model selection
A model code cannot be selected reliably from the machine category alone. Submit the installed weight, support-point layout, mounting drawing, movement method, floor condition, and required leveling tolerance for factory review.
- Plate-mount candidates — compare the approved plate drawing with the machine base before shortlisting.
- Threaded-stem candidates — confirm thread specification and engagement length before shortlisting.
- Load suitability — use only the factory-confirmed static and dynamic ratings for the selected configuration.
Procurement note
Vibration control and precision alignment
Precision machining requires the machine base to remain absolutely stable during cutting operations. The leveling foot should be tightened to full contact with the floor, creating a rigid mechanical path that bypasses the wheel entirely. For installations near heavy stamping or forging equipment, additional vibration-damping pads under the leveling foot further isolate the machine from floor-borne shock.
