The ldeal Material for Precision Machine

The latest technology in mineral casting is the non-moving parts of precision equipment made of epoxy granite. Epoxy granite is a kind of high filling composite material with quartz or granite as the main aggregate and epoxy resin as the binder. Compared with gray cast iron has the following advantages:

Vibration Damping

Damping ratio
is more than 10 times that of gray cast iron. This reduces the vibration generated during high-speed machining, improves the accuracy and speed of workpiece processing.
Corrosion Resistance

Epoxy resin
Can effectively solve the problem of immersion in oil and coolant, improving the service life and performance of equipment.
Environment-friendly

Low energy consumption
No toxic gas emissions, Reduces carbon dioxide emissions

High Precision

Linear expansion coefficient
10×10 ^-6 is less than 1/5 of cast iron. Insensitive to temperature changes, low thermal shrinkage, no local shrinkage, and less prone to thermal deformation.
Flexibility in Design

Cold casting
Allows for complex external shapes and structural designs
Cost Saving

*No aging required, saving project time and accelerating cash flow
*Parallel engineering, reducing later processing and assembly costs

Why Nano Mineral Castings?

Epoxy Granite Formula

Single natural granite aggregate More stable physical properties, higher precision can be achieved. Thanks to the small contact angle and large extension area of crushed granite, the bonding strength is high, not easy to produce cracks.

Epoxy resin as the adhesive, with a dense molecular structure and high mechanical performance.

Process

Mature Process: The process is accumulated through long-term experience.
9t/h Fully automatic pouring equipment realizes automatic measurement of different component ratios.

70t Vibration molding equipment relies on vibration frequency to eliminate bubbles, ensuring uniformity and different compaction densities, with a maximum of 2.8g/cm3.

Precision

Three precision molding methods include:

Guide rail grinding and manual grinding
Replication and coating
Synthetic surface with granite, metal and ceramic

to meet different precision needs and solve various complex problems.

Additional Service

Three factors of static stiffness, dynamic performance and thermal performance are considered in the selection of materials used for functional parts of precision machine tools.

The static stiffness reflects the structural strength and can be determined according to the mechanical properties parameter table.
Thermal performance is reflected in the deformation of the material when the temperature field changes, which can be obtained by the linear expansion coefficient of the material and the actual test data.
The dynamic performance is very abstract and the most critical factor affecting the accuracy of the machine tool, we can carry out modal testing through the Siemens modal test system, obtain the natural frequency of each component unit, combined with finite element analysis and structural improvement measures, avoid the generation of resonance, improve the dynamic performance of the machine tool.
