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

UNPARALLELED High-Precision Ceramic Straight Edge – Al₂O₃, SiC, Si₃N₄ Materials
UNPARALLELED produces high-quality ceramic measuring tools, including ceramic straight rulers, tailored to customer specifications using premium Al₂O₃ (alumina) ceramic, SiC (silicon carbide), and Si₃N₄ (silicon nitride). These precision ceramic components are ideal for ultra-precision measurement and industrial machinery applications.
Why Choose Ceramic Measuring Tools?
Compared to granite measuring instruments, ceramic measuring tools offer superior wear resistance, dimensional stability, and long-term accuracy. They are widely used in ultra-precision installations, calibration, and measurement of machinery where accuracy is critical. All UNPARALLELED ceramic measuring components are produced under ISO 9001 certified quality standards, ensuring reliable performance in industrial applications.
Applications of UNPARALLELED Ceramic Straight Edge:
- Straightness measurement of machine tool table surfaces
- Parallelism measurement of clamp surfaces
- Flatness measurement of machining tables
- Working accuracy verification on machining centers
- Precision inspection of double-column surface grinding machines
- Accuracy measurement of planer machining operations
- Surface shape inspection of lapping machines and other precision equipment
UNPARALLELED ceramic measuring tools provide the highest precision and stability for industrial and ultra-precision machining applications, making them an essential choice for modern high-end machinery.
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.
