Granite Components for Photonics and Optics

UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite components for photonics and optics in China. With abundant experience, we warmly welcome you to buy advanced granite components for photonics and optics made in China here from our factory. We also accept custom orders.

Granite Components for photonics and optics are made by granite material, which has high precision 0.001mm. Granite has unique thermal and vibration damping properties. UNPARALLELED granite base plates with very high flatness properties. These literally build the basis for high-precision applications in the semiconductor, life sciences, photonics and industrial automation markets.

 Because granite has better physical properties than metal, so photonics and optics equipments choose granite mechanical structures with high precision. Granite machine base can maintain high precision in constant temperature workshop. But there many kinds of granite material in the world, just few granite materials can be manufactured into photonics mechanical components.

All granite mechanical components with high precision are supported by ISO 9001, CE Certification...

UNPARALLELED, byword for high-end ultra-precision machines, make your precision machine more advanced.

 1 Nature Granite With Nice Physical Properties

UNPARALLELED chooses the best granite material to manufacture custom mechanical components for High-end precision machinery. UNPARALLED Granite material with stable physical characteristics and nice physical properties.

 2 1 μm ultra-high precision in operation

Each precision component is manufactured by hand lapping. UNPARALLELED has the most advanced manufacturing equipment and inspection equipment, and enforces the most strict Quality Control system.

 3 Authoritative Inspection Report

UNPARALLELED will offer authoritative inspection report for each granite component before shipping.

 4 High inherent stability

(1). Granite is a volcanic deep rock comprising the three main components quartz, feldspar and mica, formed by crystallisation of rock melts in the earth's crust.

(2). "Aged" over several thousand years, granite is homogeneous and free of internal stresses. Jinan Black Granite, for example, is about 1.4 million years old.

(3). Granite has a great hardness: Mohs' hardness up to 10.

 5 High temperature resistance

(1). Compared to metallic materials, granite has a lower coefficient of expansion (approx. 5 µm/m*K) and thus a lower absolute expansion compared to these materials (e.g. steel α = 12 µm/m*K).

(2). The lower thermal conductivity of granite (3 W/m*K) compared to steel (42-50 W/m*K) ensures a slower reaction to temperature fluctuations.

 6 Keep high precision for long time

The use of granite as a measuring plate made of natural hard stone enables very good machining with diamond tools so that machine components are manufactured with high basic accuracies.

By manual lapping, the accuracy of the guides is optimized according to the requirements to the micron.

During lapping, load-related deformations of the components can be taken into account.

This results in highly-compressed surfaces which allow the use of air bearing guides. Air bearing guides are highly accurate due to the high surface quality and contactless movement of the axes..

6. How often should I clean my granite surface plate or granite machine base?

This depends on how the plate is being used. If possible, we recommend cleaning the plate at the beginning of the day (or work shift) and again at the end. If the plate becomes soiled, particularly with oily or sticky fluids, it should probably be cleaned immediately.

Clean the plate regularly with special liquid or UNPARALLELED Waterless surface plate cleaner. The choice of cleaning solutions is important. If a volatile solvent is used (acetone, lacquer thinner, alcohol, etc.) the evaporation will chill the surface, and distort it. In this case, it is necessary to allow the plate to normalize before using it or measurement errors will occur.

The amount of time required for the plate to normalize will vary with the size of the plate, and the amount of chilling. An hour should be sufficient for smaller plates. Two hours may be needed for larger plates. If a water-based cleaner is used, there will also be some evaporative chilling.

The plate will also retain the water, and this could cause rusting of metal parts in contact with the surface. Some cleaners will also leave a sticky residue after they dry, which will attract airborne dust, and actually increase wear, rather than decreasing it.
