Precision sawing motors, which use a long time, advanced bearings, quality and stability, has been well received by our customers worldwide praise, the main salient points are: end jump small, space, cut out the product surface smooth. Carrying large and stable, making it more long motor life. Mainly used woodworking machinery, environmental protection equipment, aluminum cutting, cutting presses, cartons, packaging, printing and dyeing machinery, machining centers to do the following by the stringent requirements of the process: (1) chuck precision: ≤1.5 wire (3 ) axially movable jump: ≤1.5 wire at work among them, grease, water stains, water vapor into the interior of the motor causes the motor to be damaged. We solve this problem by the built-in seals. In order to meet the requirements of cutting the trip we made in the side of the motor stroke improved motor technology.
