Coordinate Measuring Machine Granite Air Bearing

UNPARALLELED LTD is one of the leading manufacturers and suppliers of coordinate measuring machine granite air bearing in China. With abundant experience, we warmly welcome you to buy advanced coordinate measuring machine granite air bearing made in China here from our factory. We also accept custom orders.

Coordinate Measuring Machine Granite Air Bearing is made by nice black granite. In order to realize highly accurate measurement, the surface of a coordinate measuring machine is often a surface plate made of stone. The stone surface plate has a very small change in shape over time and is not easily scratched, so it has the advantage that it can be used stably for a long time.

The development of measurement technology in recent years and decades is still exciting to follow today. In the beginning, simple measuring methods using measuring plates, measuring tables and test benches were sufficient, but over time the demands on product quality and process reliability have increased. Measurement accuracies resulted from the basic geometry of the plates used and the measurement uncertainty of the respective probes. However, measuring tasks became increasingly complex and dynamic, and results had to become more precise. This heralded the dawn of spatial coordinate metrology.

Accuracy means minimising deviations

3D coordinate measuring machines consist of a positioning system, a high-resolution measuring system, switching or measuring sensors, an evaluation system and measuring software. To achieve high measuring accuracies, the measuring deviations must be minimised.

Measurement errors are differences between the value displayed by the measuring instrument and the actual reference value of a geometric quantity (calibration standard). Modern coordinate measuring machines (CMMs) achieve a length measurement error E0 of 0.3+L/1000 µm (L is the length to be measured). The length measurement deviation is significantly influenced by the design of the measuring device, the probe, the measuring strategy, the workpiece and the user. The mechanical design is the factor that is best and most sustainable to influence.

Inherent stability, temperature resistance, vibration damping and accuracy of the guides are the four properties that make granite the ideal material for coordinate measuring machines. Granite is increasingly used in the manufacture of measuring and test benches as well as CMM's for measuring plates, measuring tables and measuring equipment. Due to the increasing demands on the precision of machines and machine components, granite is also used in other industries, e.g. machine tools, laser machines and systems, microprocessing machines, printing machines, optical machines, assembly automation, semiconductor processing and many more. 

Unparalleled can manufacture advanced grantie components for CMM Machimes. All granite machinery parts are supported by ISO 9001 Certification. UNPARALLELED, make your precision machine more advanced.

 1 High inherent stability

UNPARALLELED choose 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.

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.

"Aged" over several thousand years, granite is homogeneous and free of internal stresses. Impala, for example, is about 1.4 million years old.

Granite has a great hardness: Mohs' hardness 6 on a hardness scale up to 10.

 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.

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.

 3 Assembly and Calibration Rails and Ball Screws

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

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).

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.
