Absolute linear scale features and advantages

1. High Accuracy

The glass grating of absolute linear scale consists of two grating masks, it is the absolute mask and incremental mask respectively. Unlike normal incremental linear scale, the glass grating masks of the absolute linear scale is unique over the whole scale measurement travel. Any slight defective in the grating glass will cause the forced disposal of the whole grating glass !

Therefore, good equipment and extreme careful production process control, skill workers and comprehensive QA procedure are essentials for production of absolute grating glass and it need far more investments in whole production process ! The better grating glass quality naturally offers much higher measurement accuracy.

2. Convenient to use

The grating mask of absolute linear scale is unique over the whole measurement travels, it offers a fixed reference ( Zero Point ) to the system.

The Zero reference is physically a fixed location at the linear scale ( and hence a fixed location at the machine or measuring equipment ), it won't be affected by power failure, any accidental event or mistaken operation. This make sure the user's working coordinate is always refer from one mechanical zero location, work process inaccuracy can easily be controlled or reduced to minimal. The single and fixed zero reference feature of absolute linear scale make it much easier for secondary system error compensation. This make systems with absolute linear scale normally have much higher system accuracy.

Connector interface

Easson was established since 1995.It is a high-tech enterprise specializing in design and manufacturing of precision measuring equipment, obtained more than 20 national invention and utility model patents. Our product field in DRO systems, precision optical profile projectors, video measuring machine and etc..

Easson's factory building is specifically design and built for the manufacturing of precision measuring equipment, has four Laser interferometers for being the company's length measurement standard and R&D.

Easson is one of the few companies in the industry that has its own high-precision grating master which use own fully-developed grating master lithography equipment, produce the absolute linear encoder and high accuracy CNC linear encoder.

Our quality management system has been assessed and registered by National Quality Assurance Ltd.(NQA) against the provision of ISO 9001:2015.

Strong Technical Capabilities And Scientific Research Resources

Over the years, the company has established a very close and effective cooperative relationship with scientific research institutions such as Xi'an Jiaotong University and Jilin University, taking advantage of the abundant talents and theoretical advantages of university scientific research institutions, combined with the company's long-term accumulated technology and practical experience in this industry , so that we have created many products that are leading the domestic industry.

In addition, the company actively participates in the scientific research and industrialization projects issued by the state and Zhuhai City.

For example, in 2011, the company participated in the "High-end CNC Machine Tools and Basic Equipment" led by Xi'an Jiaotong University and issued by the Ministry of Industry and Information Technology of China "Science and Technology Major Project. And combined with Tianjin University, Hefei University of Technology, Chinese Academy of Metrology... and other units jointly developed.

The company's AS-40 series grating ruler is one of the results of this project, which is industrialized by our company. And our company's EC-2 Pseudo-random absolute coding is one of the project achievements jointly developed by our company and Jilin University.

Actively participate in industry standard setting
