Granite vs. Mineral Casting for Precision Machine Bases: How to Choose
One question, not one answer ZHHIMG manufactures both granite and mineral casting, so this article has no material to sell in advance. The honest version of the question “granite vs mineral casting” for a precision base is: which set of properties your specific structure, tolerances a...Read more -
How to Choose a Granite Surface Plate: Size, Accuracy, and Calibration
Start from the workpiece, not from the grade table Buying a granite surface plate looks simple until the quotations arrive and the grades do not match each other. The practical way through is to answer four questions in order: how big, how accurate, supported how, and verified how. This guide wal...Read more -
Custom Granite Machine Bases: A Design and Purchasing Guide for OEMs
A structural base is not a big surface plate The first thing that saves everyone time in a custom base project is understanding the difference between two products that look similar. A granite surface plate is a reference artifact: its job is to be flat, and everything about it follows from that....Read more -
Bulk Aging Treated Granite Beams Deliver Superior Dimensional Stability for Long-Term Reciprocating Operation
The core beam of high-speed gantry equipment is subjected to years of high-speed slide reciprocation, acceleration & deceleration shocks and alternating loads. Many machines pass precision inspection at commissioning, yet their reference drifts gradually after a period of operation and requir...Read more -
Granite Beams Deliver Excellent Vibration Absorption to Eliminate Micro‑Vibration Interference From High‑Speed Movement
During slide start-stop, rapid direction reversal and scanning motion of high-speed gantry equipment, continuous vibration is generated. Apart from visible large tremors, numerous barely detectable micron-scale micro-vibrations transmit directly to guide rails, linear scales and optical detection...Read more -
How to Control Internal Stress of Long-Span Precision Granite Beams After Machining?
Long-span granite beams serve as core load-bearing components for high-speed gantry equipment. A large volume of stone material is removed during machining processes such as cutting, rough grinding and grooving, which builds up internal processing stress on the surface and inside the material. Po...Read more -
How Do Granite Beams Avoid Deflection Under High‑Speed Reciprocating Motion?
The granite beam of high-speed gantry equipment carries linear motors, sliding tables, linear scales and detection modules. When the slide moves back and forth rapidly across the beam span, the load position keeps changing and easily triggers dynamic deflection. Once beam deflection occurs, guide...Read more -
Will The Relatively Heavy Self-Weight of Granite Beams Affect The Dynamic Response Speed of Machine Tools?
During the selection phase for high-speed gantry equipment, engineers often face a contradiction: granite beams feature excellent rigidity and thermal stability yet have high density and greater self-weight. Many clients raise a question: will the heavy self-weight of granite beams hinder acceler...Read more -
Why Are Precision Granite Beams Suitable for the Core Transmission Parts of High‑Speed Gantry Equipment?
For high-speed gantry machining and inspection equipment, the core transmission beam bears all loads from linear motors, linear scales, guide rails, cutting heads and inspection modules. Gantry structures feature large spans. Even extremely minor deformation, tremor or thermal drift of the beam d...Read more -
Heavy-Duty Granite Machine Tool Bases With Sufficient Self-Weight Resist Displacement And Shaking During Equipment Operation
1. Inertia Principle: Self-Weight Acts As The First Barrier Against Displacement Reaction impact forces are produced when motion mechanisms start and stop. A base with lighter mass can be easily pushed by impact force, resulting in tiny slippage or oscillation, which directly worsens positioning ...Read more -
Will Granite Machine Tool Bases Experience Precision Degradation During Long-Hour Continuous Machining?
In ultra-precision manufacturing, equipment often needs to run continuously without interruption. Production lines for semiconductors, laser processing and precision inspection usually operate 24 hours a day. Many equipment procurement engineers raise a key question: will granite machine tool bas...Read more -
What Should Be Noted for Embedding and Assembly Threaded Holes on Granite Machine Tool Bases?
Boasting ultra-low deformation, high rigidity and excellent temperature stability, granite machine tool bases have become the core reference carriers for ultra-precision machining, semiconductor equipment and laser inspection equipment. In the whole production process of the base, surface fine gr...Read more
