ISO9001CE Glass Linear Scale KA500mm Encoder For Milling Bothe Machine

SINO is China's most famous international brand. Our factory is a professional factory dedicated to the manufacture of encoder numerical display. After several years of research and production.

All KA series of linear encoders have passed the strict quality examination by the advanced dynamic laser interferometer to ensure high precision. Test reports are provided.

KA-500 is a mini-encoder specially designed for the machine tool which has a low installation size and small operation space. It can meet the needs of those customers who have requirements for the position. The length is 70~470m.KA 500 is a super-miniaturethinrule, it facilitates the use in some narrow places and the installation of a special purpose measuring instrument.

Principle of Installation

1. The encoder must be installed with the guide rail of the machine tool as the benchmark and be kept in parallel. The center of the encoder measuring range must be positioned in the center of the travel of the machine tool. Ensure that the actual measuring range of the encoder is higher than the maximum travel of the machine tool.

2. The installation shall be based on the priority principle such that the encoder shall be installed close to the drive screw of the machine tool. After installation, the body of the encoder moves with the workbench, while the reading head is fixed on the machine tool.

3. The encoder shall be so installed that it will not obstacle the operation or reduce the function of the machine tool.

4. After installation, the encoder shall be kept from a knock. During machining, it shall not obstacle the handle of a machine tool or affect the brake or other protrusions. It is not easy to contact when a workpiece drops.

5. The encoder shall be vertically installed, as shown in Fig.20. But wherever impermissible, horizontal installation is also acceptable. Never install the encoder upside down (that is, reading head on top and encoder body at lower). Never direct the rubber seal of the encoder toward the outlet of cooling oil from the machine tool.
