Granite Straightedges and Master Squares: How to Choose for Machine Alignment
Alignment work on a machine usually comes down to two questions: how much does this surface deviate along a line, and how much does it deviate from 90 degrees. Two granite reference tools answer these questions: the straightedge for straightness along a length, and the master square for squarenes...Read more -
Threaded Inserts in Granite Machine Bases: Design and Mounting Considerations
Most questions we receive about threaded inserts in granite machine bases come from assembly engineers rather than buyers. The stone itself is rarely the concern; the connection points are. Will the guide rail bolts line up? Which thread should a sensor bracket use? Can a lifting point take the l...Read more -
Why is Granite Air Bearing Base Preferred for Large-Stroke Precision Motion Stages?
Large-stroke precision motion stages are widely used in semiconductor inspection, large-area optical scanning, high-precision PCB drilling, perovskite film coating and other scenarios. When the effective stroke extends to several meters, the platform faces great challenges in accuracy retention, ...Read more -
Will the Air Film Stability of Granite Air Bearing Base Degrade During Long-Term Operation?
In high-end equipment such as semiconductor optical platforms, ultra-precision laser processing and coordinate measuring machines, granite air bearing bases rely on thin air films to achieve frictionless motion. The long-term stability of the air film directly determines the durability of equipme...Read more -
Custom Granite Machine Base RFQ Checklist: Drawings, Tolerances and Inspection Requirements
Many requests for a custom granite machine base go through three or four rounds of emails before anyone can actually quote. The reason is rarely the price discussion; it is missing information: no drawing revision number, tolerances described in words instead of on the drawing, or no agreement on...Read more -
How to Control the Precision of Air Holes and Air Outlet Surface During Machining of Granite Air Bearing Base
The performance ceiling of ultra-precision air-floating motion systems often depends on the microholes and air outlet end faces of granite air bearing bases. Many people focus on the flatness of the stone substrate, yet easily overlook that the consistency of air hole diameter, the morphology of ...Read more -
Granite vs Mineral Casting vs Cast Iron Machine Bases: How to Choose
Every precision machine project eventually reaches the same meeting: the base material has to be fixed before the design can move forward. And the honest answer to “which material should we use?” is that no single material wins everywhere. The right choice among granite, mineral casti...Read more -
Temperature Adaptive Stability Technology: Unlocking the Core Logic of Granite Air Bearing Base against Precision Drift
In the field of ultra-precision motion and metrology, the biggest enemy of precision is not machining error, but dynamic disturbance of temperature field. Even a 0.5℃ ambient temperature difference, micro heat accumulation generated during equipment operation, and airflow changes caused by day-ni...Read more -
How to Choose a Granite Surface Plate: Size, Accuracy Grade, Support and Calibration
Buying a granite surface plate looks simple on the surface: pick a size, pick a grade, compare prices. In practice, two plates with almost identical spec sheets can perform very differently on your floor. The difference usually comes down to five decisions that should be made before you request a...Read more -
