Ordinary Discount Lmage Processing Apparatus - Granite Rectangle Square Ruler with 0.001mm precision – ZHONGHUI

The granite square is one of the main product series in the gage series, also called the marble square ruler or square ruler. ZhongHui Granite Square Ruler includes 90° special tools such as inspection square ruler, square ruler, bent plate, etc. It can assist the machine tool and machinery manufacturing user to perform right angle inspection and scribing on parts/workpieces and measure the perpendicular of the parts. The plane accuracy standard GB, DIN, JJS, ASME… Weight reduction holes are added to reduce weight and facilitate processing.
The main minerals of the granite square are the escaping stone, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, and structural precision code.After aging for hundreds of millions of years, the texture is uniform, the stability is good, and the strength is high. High hardness, can maintain high precision under heavy load.Suitable for industrial production and laboratory measurements.

Granite square ruler is mainly used to check the flatness of parts. Granite gages are the basic equipment used in industrial inspection and are suitable for inspection of instrumentation, precision tools, mechanical parts and high-precision measurement.
Granite square can be used in the calibration and assembly of precision machines such as CMM Machines, CNC Machine, Laser machines…
1.The rock has long-term natural aging, uniform organization structure, minimal linear expansion coefficient,internal stress completely disappeared, no deformation, and therefore high precision.
2. good rigidity, high hardness,strong wear resistance.
3. not afraid of acid, liquid material erosion, will not rust, do not have to oil, easy to stick dust, maintenance, easy maintenance, long service life.
4. no scratches, not subject to constant temperature conditions, at room temperature can also maintain the accuracy of temperature measurement.
Granite square material: Mainly composed of granite, the main minerals are pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite, black gloss, structural precision, after millions of years of aging, uniform texture Good stability, high strength, high hardness, can maintain high precision under heavy load.Suitable for industrial production and laboratory measurements.

Granite Square Features and Benefits:
1.The granite has dense structure , smooth surface and wear-resistance, and small roughness value.
2.Afera long perod of natural aging,. the intermalstress is completely disappeared and the material is stable and will not bedeformed.
3, acid, alkali, corrosion resistance, anti-magnetic.
4, will not rust rusty, easy to use and maintain.
5, linear expansion coefficient is small, affected by the temperature.

1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
