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

This ceramic square ruler is made by SiC ceramic. The function of Precision Ceramic Rulers are similar to Granite Ruler. But Precision Ceramic is better and the price is higher than precision granite measuring.
According to customers' requests, we are able to provide finished parts to tight tolerance for most technical ceramics with high degree of accuracy for CMM machines and other precision machines. These ceramic materials can be machined by diamond grinding to very precise tolerances for dimension, flatness, wedge, roundness,an cyindrcty a required. lery tight as-ground tolerances are routine, and most features can also be mechanically polished to optical quality. Our technicians are also willing to review your design and provide feedback on machining feasibility including material and cost drivers such as key tolerances etc according to request.
All precision ceramic machinery parts are supported by ISO 9001 Certification. UNPARALLELED, byword for high-end ultra-precision machines, make your precision machine more advanced.
Why choose UNPRALLELED advanced ceramic square ruler?
•Best suited for high-precision measurement
High precision measurement of squareness and straightness to within 2 μm or less per up to 1000 mm achieved.
•Lightweight and easy to measure and carry around
As compared to the 4-plane finished square masters made of Metal and Granite, a ceramic master is lightweight and is easy to measure and carry around.
•Small deflection and superb abrasion resistance
Because of its light weight and high rigidity, the master provides small deflection under its own weight and outstanding abrasion resistance. (Young’s modulus: 380 GPa)
•Little change over time
The ceramic 4-plane finished square master provides high hardness and outstanding abrasion resistance. Furthermore, it has a small coefficient of thermal expansion, which results in small deformation caused by temperature changes and makes it less susceptible to environmental influences during measurement.

1 High End Material---Ceramic
UNPARALLELED choose the best ceramic material to manufacture custom mechanical components for High-end precision machinery. UNPARALLED ceramic material with stable physical characteristics and nice physical properties.

2 1 μm ultra-high precision in operation
It can be said very stable in secular variation by our company after a 5-year inspection and examination.

3 Lighter Weight
It is almost the same as granite in specific gravity but it would be hollow.Owing to the hollow,the gravity of unit volume of the granite is lighter than same volume granite. So it is easier to start and stop for using as the machinery component.

4 Stable Physical Properties
It is in the thermal expansion coefficient,about 1/2 of the stainless steel,and stable in any temperature changes. Because it's extension modulus is 1/2 of the stainless steel, it is better to be critically processed.In addition the whole precision will not be destroyed with the pressing-mark.

5 Good Wear Resistance
It is considered as the best material because of its hardness; and wear able capacity (5 times higher than granite's)

6 Keep high precision for long time
The instinctive vibration frequency has the close relation with the extension modulus and specific gravity of the materials. It is high in the vibration frequency,extensive in used-eddy range and betters in shockproof.AII those can satisfy with the requirement of the higher precision of the measure tools and machinery component.lt can satisfy with the following requirements seen from the function:
• It is most important for a measuring tool to get a higher precision standard.And now,much more attention is being focused to the newma^ena - ceramic,and it can be seen as the modern material because of Its advanced performance,such as thermal expansion.secular vanation.hardness, rigidity.wearable capability,etc.
• It will guarantee a fast measuring speed and a high- efflciency,depending on its own rigidity and specific gravity.
• Considered its rationality and stability, it need not the special maintenance.lt is antl-rust.corroslon resistance and wearable resistance so it is believed as an ideal material for the high precision measuring tool and machinery component.
