I. Preferred Material
Jinan Black Granite (Black Biotite Granite, JJG Standard Grade)
Natural internal stress fully released, almost no deformation for decades
Low coefficient of thermal expansion, minimal impact of temperature changes on precision
Good damping, anti-vibration, suitable for machine tools, CMMs, and automation equipment
High hardness, wear-resistant, suitable for guide surfaces and reference platforms<\/p>\n\n\n\n

II. Precision Grades (General Industrial High Precision Standards)
By common flatness grades:
Grade 00: Metrology rooms, CMMs, precision inspection platforms
Grade 0: Automation equipment, precision machine tools, inspection workbenches
Grade 1: General tooling, marking platforms, general equipment bases
Recommended for general high precision guide platforms: Grade 00 or Grade 0
Grade 00 Flatness: \u22480.03\u20130.06 \u03bcm\/mm (calculated by size)
Surface Roughness: Ra \u2264 0.2~0.4 \u03bcm
Guide rails slide smoothly, scratch-free, and wear-resistant<\/p>\n\n\n\n

III. Structure and Stability Design (Industry Standard Practices)
Solid monolithic structure
No splicing, no deep grooves, ensuring overall rigidity and stability
T-slots or embedded guide strips
Directly ground granite for sliding guides
Or embedded high-precision linear guides (THK\/PMI, etc.)
Bottom rib design
Reduces deformation under load, improves long-term stability
Multi-point support structure
3-point or 4-point adjustable supports, ensuring uniform load distribution and no deformation<\/p>\n\n\n\n

IV. Surface Finishing (Guaranteeing Precision Durability)
Precision grinding polishing, no pores, no cracks
Guide surfaces free of scratches, chipping, and hidden cracks
Threaded holes and mounting holes precisely machined
Waterproof and oil-proof protective treatment available<\/p>\n\n\n\n

V. Applicable Equipment
CMM worktables
Precision grinders, CNC routers, precision machining centers
Automation inspection line platforms
Bases for laser equipment and vision inspection equipment
Semiconductor and precision assembly workbenches<\/p>\n\n\n\n

VI. Summary
Industrial general-purpose, high-precision, high-stability granite guide platform = Jinan Black Granite Grade 00\/0 precision Solid monolithic structure Precision ground guide surfaces.<\/p>\n\n\n\n
