Precision Equipment: Material Selection Comparison of Ceramics, Metals, and Granite Complete Selection Logic
I. Overview of Core Characteristics (Quick Differentiation)<\/p>\n\n\n\n

    \n
  1. Granite (Natural Stone)
    Pros: Excellent vibration damping, extremely low thermal expansion, non-magnetic insulation, low cost, mature large-area base technology;
    Cons: Natural texture and impurities, prone to chipping at small holes\/thin walls, cannot be made into complex irregular shapes, very heavy, absorbs water and oil stains, slight creep under long-term heavy pressure.<\/li>\n\n\n\n
  2. Metal (Aluminum \/ Steel \/ Cast Iron)
    Pros: Easy to machine, supports complex structures, lightweight thin walls, no chipping when drilling\/tapping, flexible assembly, fast delivery;
    Cons: Significant thermal expansion\/contraction, prone to vibration resonance, steel rusts, conductive and magnetic, creep under long-term stress, poor precision stability.<\/li>\n\n\n\n
  3. Precision Ceramics (Silicon Carbide \/ Alumina Ceramics)
    Combines the strengths of both and compensates for their weaknesses
    Inherits from stone: Low thermal expansion, high vibration damping, non-magnetic insulation, corrosion resistance, ultra-high hardness and wear resistance;
    Inherits from metal: Precision machining of small holes, through holes, embedded threads, irregular thin walls, and integrated structures;
    Unique advantages: Uniform material without natural defects, non-absorbent to oil\/stains, zero creep, high-temperature stability, lighter weight with the same rigidity.
    II. Scenario-Based Selection Criteria (Directly match your equipment)
    Scenario 1: Large fixed inspection platforms, CMM machine bases \u2192 Prioritize Granite
    Suitable for: Large dimensions, stationary, limited budget, no need for dense small holes \/ complex slots
    Disadvantages: Not recommended if dense bolt holes, ultra-thin structures, or high-speed movement are required.
    Scenario 2: High-speed motion modules, lightweight motion brackets, small precision tooling \u2192 Prioritize Metal (Aluminum Alloy \/ Steel)
    Suitable for: Complex structures, low-cost mass production, minimal temperature changes, short-term use, no strict requirements for long-term precision
    Disadvantages: Not suitable for hot\/cold environments or high-precision optical \/ semiconductor equipment, as precision will drift.
    Scenario 3: High-precision optics, semiconductors, laser equipment, high-speed precision moving parts, small high-precision bases \u2192 Prioritize Ceramics
    Ceramics are the optimal solution if any of the following apply:
    Need for dense small holes, through holes, or bottom-mounted isolation pillars (like the customer’s previous 4-inch plate with dense bolt structure);
    Equipment requires high-speed reciprocating motion, needing both vibration damping lightweight;
    Strict temperature-variable environment, where micron-level precision must not drift during long-term operation;
    Non-magnetic insulation required to avoid electromagnetic interference with optics \/ chips;
    Contact with acid\/alkaline cutting fluids, requiring never to rust and not absorb oil stains;
    Thin-walled, irregular integrated structures where natural stone is prone to shattering.
