From raw blocks in the mine to precision mechanical components, the core process of granite is “mining → material selection → rough cutting → aging → precision cutting → CNC shaping → grinding and polishing → hole systems / inserts → inspection → protection”. Stress and precision are strictly controlled throughout the process, ultimately achieving…
The price of high-precision granite platforms is primarily influenced by seven key factors: material grade, dimensions and thickness, precision grade, customized processing, aging treatment, brand and service, and transportation and installation. Among these, precision and material have the greatest impact on price, potentially causing a price difference of several times for products of the same…

Reasons why high-precision granite platforms become the cornerstone of high-end laser equipmentExcellent thermal stabilityThe coefficient of thermal expansion is far lower than that of steel and aluminum, resulting in minimal deformation during ambient temperature fluctuations, firmly locking the laser focus and optical path position, and eliminating precision drift.Strong vibration damping and suppression capabilityThe dense microcrystalline…
With its four core advantages of extremely low thermal expansion coefficient, high rigidity, strong vibration damping, corrosion resistance, granite has become the preferred structural material for laser equipment (especially high-precision and micro-machining types). It is widely used in bases, gantries, optical, and precision tooling, supporting nanometer-level stability and micrometer-level machining accuracy. I. Core Material Advantages…
Granite Precision Platform / Component Stacking (Splicing, Stacking, Multi-layer) Standard SolutionCombining the actual production and usage scenarios of granite square rulers, precision platforms, and components with holes in your workshop, the stacking is divided into three major solutions: stacking, permanent splicing, and multi-layer base assembly. At the same time, it strictly matches 000/00/0 grade precision…
Standard practices are divided into two categories: precision adjustable bolt fixing (preferred) and pressure plate flexible cushion (secondary rigid deadlocking and direct steel-to-steel contact are strictly prohibited. I. Preferred: Bolt Dowel Pin Adjustable Support (Industrial Precision Standard) II.: Pressure Plate Fixing (Lightweight/Frequent Disassembly) III. Strictly Prohibited Methods (Damages Precision/Cracks Platform) IV. Standard (Ready for Implementation)…
Granite Precision Gauges: How Accuracy Grade Directly Determines Service LifeA brief summary of the core logic: The higher the accuracy grade (000 > 00 > 0 > 1 > 2), the stricter the requirements for material, processing, operating environment, and maintenance. The theoretical physical lifespan is longer, but the effective accuracy lifespan is shorter; low-grade…
Accuracy Grade Classification of Granite Precision Gauges (Surface Plates / Platforms)Domestically, the mainstream standard is GB/T 20428-2021 “Rock Surface Plates”, while internationally, ISO 8512-2 and DIN 876 are commonly used. The core classification is based on flatness tolerance, distinguishing grades 000, 00, 0, 1, and 2, with accuracy decreasing from high to low.I. National Standard…
