Granite Triangle Ruler

The Granite Triangle Ruler is a kind of precision measuring tool made of natural granite.Here is a detailed introduction:

Characteristics

High Precision:It is made of high-quality natural granite and processed through precise manufacturing techniques,which enables it to achieve a very high level of flatness and accuracy.It can meet various high-precision measurement requirements,and the error can be controlled within a very small range.

Good Stability:The internal stress of the granite material has been completely relieved,and its structure is uniform with a very small coefficient of linear expansion.It is not easily affected by environmental factors such as temperature and humidity,thus maintaining stable measurement accuracy over a long period.

Excellent Wear-Resistance:Granite is very hard,with a hardness 2-3 times higher than that of cast iron.It is highly resistant to wear and tear,and is not easily damaged by friction with the measured object during long-term use.This ensures the good quality of its measurement surface.

Strong Corrosion-Resistance:It has good resistance to most chemical substances,and can adapt to a variety of complex working environments.It is not easily corroded by acids,alkalis and other chemical substances,which extends its service life.

Specifications and Accuracy

Common Specifications:There are various size specifications,such as those with right-angled sides of lengths 160mm×250mm×50mm,210mm×300mm×50mm,300mm×400mm×50mm,etc.Users can choose according to their actual measurement needs.

Accuracy Levels:Generally,it is divided into different accuracy levels such as grade 00 and grade 0.Grade 00 has the highest accuracy and is suitable for high-precision measurement and calibration work,while grade 0 has slightly lower accuracy and can meet the measurement tasks with general accuracy requirements.

Applications

Machining:It is used to detect the perpendicularity,angle and other parameters of mechanical parts,ensuring the machining accuracy of parts and the assembly quality of mechanical equipment.

Mold Manufacturing:In the process of mold manufacturing,it is used to measure and calibrate the angle and perpendicularity of molds,ensuring the accuracy and quality of molds,and improving the service life of molds.

Instrument Installation:It helps to install and debug instruments and meters,ensuring the accurate installation position of instruments and meters,and guaranteeing their normal operation and measurement accuracy.

Construction:In construction,it is used to measure and check the perpendicularity of walls,floors and the angles of inside and outside corners,ensuring the quality of construction projects.

Usage and Maintenance

Usage Methods:When using,the triangle ruler should be placed stably on the surface of the object to be measured,ensuring that the triangle ruler is closely attached to the object.Then,read the measurement data.For high-precision measurements,it can be used in combination with other measuring tools such as micrometers and dial indicators to improve the measurement accuracy.

Maintenance Points:Avoid collision and dropping to prevent damage to the measurement surface of the triangle ruler.Clean the surface of the triangle ruler regularly to remove dust and oil stains and maintain the smoothness of the measurement surface.When not in use for a long time,the triangle ruler should be placed in a dry and ventilated place,and its surface should be coated with anti-rust oil or a special protective agent to prevent rust and corrosion.
