The core logic of selecting a platform is to first clarify equipment requirements, then match materials, precisio, structure, and supporting solutions, avoiding the pitfalls of “wasting money on excessive precision” or “being unable to use it due to insufficient precision.”
I. Step One: First Undnd Your Core Requirements (Set the Direction)
Before inquiring for a quote or selecting a model, clarify these 4 questions first; this is the foundation of all selection processes:
What eqment will it be used for?
Requirements for platforms vary drastically between different equipment:
CMMs / High-precision inspection equipment: Require the highest flatness and stability;
Semiconductor /hy equipment: Require additional non-magnetic, low thermal deformation, and high cleanliness properties;
Laser cutting / machining equipment: Prioritize rigidity, vibration damping, and customized moting holes;
Ordinary tooling / positioning equipment: Lower precision requirements; an economical model is sufficient.
What is the working environment of the equipment?
Are there vibration sources in the worhop (presses, air compressors, overhead cranes)?
How large are the temperature fluctuations (±5°C or above vs. constant temperature workshop)?
Are there corrosive media sus acids, alkalis, or oil stains?
Total equipment weight table installation dimensions?
Total equipment weight determines the platform thickness and load-bearing design; installation dimensions determine the platform length adth, as well as whether custom T-slots or mounting holes are needed.
What is your acceptable budget and delivery cycle?
Precision, material grade, and processing complexity directly affect price and time; clarifying this in advance avoids ineffective communication.
II. Step Two: Selection of Key Performance Indicators (Look at Hard Parameters)
- Stone Grade: Choosing the rigt “material” can double performance
For granite vibration damping platforms, premium black granites such as Jinan Qing (Shandong Black) and Shanxi Black are preferred. Prioritize towing points:
Mineral structure: The denser and more uniform the crystal grains, the better; no cracks, no pinholes, no porosity; high internal damping ensures stable vibraping effects;
Density: ≥2.95g/cm³; the higher the density, the greater the self-weight inertia, and the better the vibration suppression effect;
Nognetic / Low magnetic: Semiconductor and optical inspection equipment must use non-magnetic granite to avoid magnetic interference affecting measurement/processing accuracy;
Water absorption rate: ≤0.1%; the lowr absorption rate, the stronger the resistance to oil stains and corrosion, and the less likely to deform due to moisture. - Precision Grade: Choose according to needs, do not bl pursue high precision
Platform precision directly affects the final performance of the equipment. Common grades are as follows (using flatness as an example):
Cuadro
Precision Grade Flatnessnce (Example: 1000×1000mm Platform) Applicable Scenario
00 Grade (Ultra-high precision) ≤2μmser interferometers, lithography machines, wafer inspection equipment
0 Grade (High precision) ≤5μm Imaging systems, precision inspection tables, optical experimentorms
1 Grade (Industrial grade) ≤10μm Ordinary machine tool tooling, automation equipment bases, positioning platforms
⚠️ Note: The higher the precisione higher the price and processing difficulty. Do not choose Grade 00 unless necessary. For example, a standard CNC carving machine is fully sufficient with a Grade 0 platf - Size and Load-bearing: Calculate if it is “sufficient”
Size: The platform length and width should be 100-200mm larger than the equipment on each side to reserve space for installation and operation;
Thickness: Directly determines load-bearing capacity and rigidity. Industry general reference:
Within1000×1000mm, total equipment weight ≤500kg: Select 150-200mm thick;
1000-2000mm, total equipent weight 500-1500kg: Select 200-300mm thick;
For ultra-large equipment or heavy-load scenarios: reinforcement ribs or box-type structures are required to prevent deformation under long-term loads.
III. Step 3: Customization and Supporting Components (Adapt to Your Equipment)
A significant portion of the value of a granite platform lies in customization. You must confirm the following points with the manufacturer:
Installation and Fixing Structure
Do you need custom T-slots, threaded holes, counterbored holes, or locating pin holes? The hole dimensions and positional tolerances must match your equipment base 100%;
For large equipment, do you need a spliced platform? The flatness and sealing of the splicing seam must be strictly controlled.
Vibration Damping System Configuration
The vibration damping effect of the platform relies half on the stone itself and half on the supporting dampers:
Ordinary workshops (no strong vibration): Select rubber damping pads / adjustable leveling feet;
Strong vibration sources (presses, air compressors): Must select air-bearing dampers / passive vibration isolation platforms to cut off ground vibration transmission;
High-precision optical / semiconductor equipment: Can upgrade to an active vibration isolation system to handle low-frequency micro-vibrations.
Surface Treatment and Special Requirements
Ordinary equipment: Only requires precision grinding and rust-proof sealing treatment;
Clean rooms / Semiconductor equipment: Requires mirror polishing and clean sealing to avoid dust and oil residue;
Special environments: Can apply acid and alkali-resistant coatings to improve corrosion resistance.
IV. Step 4: Manufacturer and Delivery Assurance (Key to Avoiding Pitfalls)
Check Processing Capabilities and Inspection Reports
Request the manufacturer to provide inspection reports for the platform’s flatness, parallelism, and perpendicularity; preferably issued by a third-party metrology institution to avoid purchasing “verbally high-precision” products;
Check Aging Treatment Process
High-quality platforms undergo natural aging artificial aging (vibration / heat treatment) to eliminate internal stress and avoid deformation later; inferior products lack aging treatment and will experience precision drift within half a year;
Check After-sales and Calibration Services
For high-precision platforms, it is recommended to choose manufacturers that support on-site calibration and maintenance, especially for large platforms, as on-site calibration ensures installation accuracy;
Check Packaging and Transportation
Granite platforms are precision components prone to bumps and breakage during transport; require the manufacturer to use full protection packaging with wooden frames foam shock pads to avoid damage upon delivery.
