For the worktable of high-precision Coordinate Measuring Machines (CMMs), the preferred material is high-qualision granite (mainly Jinan Black); industrial ceramics can be selected for ultra-high precision scenarios; and aluminum alloy is suitable for general or mobile types.<\/p>\n\n\n\n

I. Preferred: Precisin Granite (Jinan Black) \u2014 The Standard for 95% of Metrology CMMs
Core Advantages (Best for Worktables)
Extremely strong stability: Aged naver millions of years, internal stress fully released, no deformation over the long term
Good thermal stability: Coefficient of thermal expansion \u2248 1\/2 oteel, 1\/4 of aluminum, minimizing the impact of temperature fluctuations
High rigidity and good anti-vibration: Strong damping capability, absorbs ground and workpiece vibrations, ensuring stable measurement
Easy ee precision: Precision grinding can achieve flatness \u2264 2 \u03bcm\/m, wear-resistant, rust-proof
Full machine thermal matching: Worktable, crossbeam, and guides made of the same material, consistent thermal deformation<\/p>\n\n\n\n

Disadvantages
Heavy weight, high brittleness, vulnerable to severe impact
High cost and complex transportation\/installation for large ps
Applicable Scenarios
Fixed bridge, gantry, and high-precision metrology room CMMs
Workshop sites, environments with large temperature fluctuations
Benchmark measurement equipment requirigh long-term stability<\/p>\n\n\n\n

II. Alternative: Industrial Ceramic (High-end \/ Ultra-precision)
Ventajas
Extremely high specific stiffness (rigidity\/weight): Approximately 6 tt of granite, 4 times that of aluminum alloy
Extremely low coefficient of thermal expansion, lightweight, fast dynamic response
Wear-resistant, corrosion-resistant, long-term stability clos to granite
Disadvantages
Difficult to process, expensive
High brittleness, strict design and installation requirements
Applicable Scenarios
Ultra-high precision, high-speed canning CMMs (mostly mobile bridges\/crossbeams, rarely full worktables)<\/p>\n\n\n\n

III. Alternative: Aluminum Alloy (Lightweight \/ Mobile \/ Economical)
Ventajas
Lightght, easy to process, lower cost
Flexible structural design (can be hollow or complex structures)
Disadvantages
High coefficient of thermal expansion (\u2248 4 times that of granite), temperature
Low hardness, poor wear resistance, long-term stability inferior to stone
Applicable Scenarios
Portable, cantilever, small\/economical CMMs
Constantenvironments, scenarios with moderate precision requirements<\/p>\n\n\n\n

V. Purchase Recommendations
High precision \/ Metrology room \/ Workshop site \u2192 Chooranite (most reliable, most universal)
Ultra-high speed \/ Ultra-high precision \u2192 Ceramic (crossbeam \/ moving parts)
Portable \/ Small \/ Economical \u2192 Aluminum alloy
Suary: For CMM worktables, precision granite is the first choice, offering the best overall combination of stability, precision,<\/p>\n\n\n\n
