The grating ruler, also called the grating ruler displacement sensor (the grating ruler sensor), is a measurement feedback device that uses the optical principle of the grating. Grating rulers are often used in closed-loop servo systems of CNC machine tools, and can be used to detect linear or angular displacement. The measured output signal is a digital pulse, which has the characteristics of large detection range, high detection accuracy and fast response speed......

The successful development of the ball scale system is based on its innovative non-contact inductive encoder. This design has a strong anti-fouling ability, such as resistance to dust, iron filings, oil and other environmental conditions, while achieving measurement, high protection level and zero mechanical hysteresis. These all ensure that the user's machine runs reliably without excessive maintenance. Not only that, the series of ball grid systems are also easy to install...

The installation of the magnetic scale is very important. The installation method manual must be very detailed and clear. You should read it carefully. The cable should also have a standard, if not, see the interface definition on the manual. The connection method with the computer depends on the type of your grating ruler (many types). For example, if your magnetic scale is absolute and the interface is 232, then you can directly connect to the 232 interface of the computer, and then use a 232 debugging software (many online) to directly read the magnetic scale data. .....

The essence of the magnetic grid measuring displacement is to measure the positional weighing with the magnetic grid pitch as a standard ruler. High-resolution magnetic scales are generally more expensive and difficult to manufacture. In order to improve the resolution of the system, it is necessary to subdivide the moiré fringe, and the magnetic scale sensor system mostly adopts the electronic subdivision method. When the two magnetic grids overlap at a slight inclination angle, moiré fringes will be generated in the direction roughly perpendicular to the grating scribe line. As the magnetic grid moves, the moiré fringes will also move up and down......

Generally, the main ruler is installed on the worktable (sliding board) of the machine tool, and the bed moves with the knife. The reading head is fixed on the bed, and the reading head is installed below the main ruler as much as possible. The choice of the installation method must pay attention to the direction of the chips, cutting fluid and oil splashing. If it is necessary to install with the reading head facing up due to the limitation of the installation position, an auxiliary sealing device must be added...
