Product Overview
[Company Name] specializes in designing and manufacturing Precision Granite Components for the global high-tech industry. Moving beyond simple surface plates, we produce complex structural parts including machine beds, columns, beams, and guide rails made from 100% natural fine-grain granite.
Compared to cast iron or mineral casting, our natural granite components offer unmatched long-term stability, superior vibration damping, and zero thermal deformation. Manufactured in compliance with ISO 1101, DIN 876, and ASME standards, these components are the preferred choice for manufacturers of CNC machines, laser systems, semiconductor equipment, and medical imaging devices.
Key Features & Benefits
- Structural Stability & Rigidity Natural granite has excellent compressive strength and geometric stability. Ideal for heavy-duty machine bases that require zero deformation over decades.
- Superior Vibration Damping Granite's natural damping capacity is 6-10x higher than cast iron. Reduces machine vibration, improving surface finish and tool life.
- Thermal Insulation & Stability Low thermal conductivity and expansion coefficient ensure high precision even in fluctuating workshop temperatures.
- Corrosion & Rust Free Completely immune to coolants, oils, and chemicals. No rust particles to contaminate sensitive processes (e.g., semiconductor wafer handling).
- Non-Magnetic & Clean Perfect for MRI machines, electron microscopes, and magnetic-sensitive assembly lines. Generates no dust or particles during operation.
- Custom Engineering Capable of machining complex geometries, T-slots, threaded inserts, and mating surfaces to integrate seamlessly with your machine design.
Applications
- Machine Tool Industry: Beds, columns, and cross-beams for CNC grinders, EDM, and laser cutting machines.
- Semiconductor Equipment: Frames for wafer steppers, inspection systems, and bonding machines.
- Medical Devices: Bases for CT, MRI, and X-ray equipment (Non-magnetic requirement).
- Metrology Equipment: Bases and moving bridges for Coordinate Measuring Machines (CMM).
- Precision Optics: Mounting tables for laser interferometers and optical alignment systems.
Engineering & Shipping Support
- Design Collaboration: Our engineers work with your team to optimize granite structure design for rigidity and weight.
- Precision Machining: Full-service milling, grinding, and drilling using CNC stone machining centers.
- Global Logistics: Heavy-duty wooden crates with shock absorption, suitable for sea and air freight.
- Installation Guide: Detailed instructions for leveling, supporting, and assembling granite components.
Expert Care Tips
- Support Points: Use adjustable leveling mounts to ensure even weight distribution and prevent stress cracks.
- Assembly: Use torque wrenches when tightening bolts into embedded inserts to prevent over-stressing the stone.
- Environment: While stable, avoid direct exposure to extreme heat sources (>80°C) or direct sunlight.
- Cleaning: Use compressed air or alcohol wipes. Avoid harsh acids.

Q: What are precision granite components?
A: Precision granite components refer to materials made from high-quality natural granite (such as Jinan Green or Indian Black), which undergo mining, aging treatment, precision grinding, and polishing to manufacture high-precision mechanical bases, measuring platforms, guide rails, beams, and other parts. They leverage granite's physical stability to ensure equipment accuracy.
Q: Why use granite for machine bases or measuring platforms instead of cast iron or steel?
A: Compared to metallic materials, granite offers these core advantages:
• High stability: Dense rock structure with minimal internal stress ensures minimal deformation over extended use.
• Low thermal expansion coefficient: Minimal impact from temperature fluctuations, maintaining precision.
• Excellent damping properties: Strong vibration absorption reduces the effect of machine vibrations on accuracy.
• Rust-free: Resistant to acid and alkali corrosion, eliminating the need for oiling and reducing maintenance costs.
• Non-magnetic: Suitable for electronic or optical equipment sensitive to magnetic fields.
Q: Does the precision of granite components deteriorate over time?
A: Natural granite achieves exceptional stability through natural and artificial aging processes. Under normal use and maintenance, its precision remains unchanged for decades. However, precision may be compromised by impacts, uneven heating, or improper support.
Q: How can screws or other components be secured to granite?
A: Granite cannot be directly tapped (risk of chipping). Common methods include:
• Threaded inserts: Drill holes, inject specialized adhesive, and embed metal threaded inserts.
• T-slots: Machine T-slots for use with bolts and clamping plates.
• Blind holes + adhesive bonding: Secure metal components using epoxy resin adhesive.
Q: Does ambient temperature affect granite components?
A: Although granite has a low thermal expansion coefficient, temperature control is still required for ultra-high precision (micron-level) applications.
• Standard temperature: 20°C ±2°C.
• Heat sources: Avoid direct sunlight, proximity to heating equipment, and prolonged contact of body heat with measurement surfaces.
