Granite Tri Square Ruler

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

UNPARALLELED® Granite Tri Square Rulers are made by nice Black Granite with density: 3070kg/m3 with four precision surfaces, which is suitable for measuring and calibration in assembly and inspection of CNC, LASER Machines, CMM Machines, semiconductor equipment, metrology equipment and vision equipment in laboratories.

Striving ahead of the regular industry trends, UNPARALLELED® strives to produce high quality precision granite triangular square(also called granite tri square). Using finest black granite as the raw material, the precisiongranite triangular square is ideally used to check out the three coordinates (i.e. X, Y and Z axis of a spectrum data of machined components). The function of Granite Tri Square Ruler issimilar with Granite Square Ruler. lt can assist the machine tool and machinery manufacturinguser to perform right angle inspection and scribing on parts/workpieces and measure theperpendicular ofthe parts.

All granite tri square rulers are tested in a temperature (20°C) and humidity controlled environment.

All UNPARALLELED® granite measuring tools are supplied with a Test Report, in which error map and installation instructions are reported.

UNPARALLELED® can supply granite tri square ruler with different sizes according to customer needs and drawings, with holes, threaded inserts, guide or clamping T-slots, clearing grooves and with rubber feet (for the smaller sizes).

All granite machinery parts are supported by ISO 9001 Certification.

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

 1 High End Material---Black Granite

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.

 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 th 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..
