Reconstruction of machine tool of grating digital display system display

The grating ruler, also known as the grating displacement sensor ( raster sensor ), is a measure of feedback device using optical principle of grating. Closed loop servo system grating ruler is often used in CNC machine tools, can be used as a linear displacement or angular displacement detection. The measurement of output signal is a digital pulse, with large detection range, high precision, fast response characteristics.

For example, in the numerical control machine tools used in the coordinate of tool and workpiece were detected, to observe and track moving error, to the motion error of a compensation tool function.

Definition: grating grating by Moore fringe theory, through the photoelectric conversion, digital representation of high precision displacement sensor linear displacement. Grating linear displacement sensor is mainly applied to linear motion guide mechanism, accurate display and can realize automatic control of mobile content, control is widely applied in the metal cutting machine tool processing digital display and CNC machining center position loop. The product has formed a series, all kinds of machine tools for the selection of different specifications, range from 50 mm to 30 m, covering almost all metal cutting machine tool stroke

The main application of raster ruler:

1, all kinds of measuring displacement measurement mechanism, instrument: spring testing machine, three coordinate measuring machine, projector

2 digital display system, all kinds of machine tools, milling machine, grinder: lathe, boring machine, drilling machine, electric spark etc.

3, the use of various types of CNC machine tools supporting: CNC milling, machining centers, CNC grinding

Then, with PLC 4, used to measure displacement of various types of automation mechanism.

Product features: 1, the most advanced optical measurement system, design of high precision five bearing system with reliable and durable, to ensure the stability of the optical mechanical system, excellent repeatability and high measurement accuracy class.

2, the sensor adopts a sealing structure, reliable performance, convenient installation.

3, using a special oil resistance, corrosion resistance, high elasticity and anti-aging plastic waterproof, dustproof is excellent, the service life is long.

4, the high level of anti-interference ability, stable and reliable.

5, the light source adopts imported infrared emitting diode, small size and long life.

6, the use of advanced production technology of grating, can produce various specifications of the high precision grating glass ruler.
