1. The first reason is the quality of the spindle of the engraving machine. That is to say, the quality of the spindle itself does not contribute to the damage of the bearing. The use of a bearing with a very poor quality makes the life of the engraving machine spindle shorter at high speed, and it is easy to be damaged.
2. The second reason is that the engraving spindle cooling system has no effect. The water cooling system of the engraving machine spindle is water-cooled. If the long-term water circulation is not good, or the water circulation cycle is forgotten, over time, a hot-lift effect will occur, resulting in increased friction and bearing damage.
3. The third reason is related to the specific operation of the engraving machine. Some spindle speeds have not yet reached the beginning of engraving, which can easily cause damage to the bearings. Some customers do not have the same resistance when carving, and they do not adjust the speed in time. The spindle of the engraving machine is damaged.
4, the fourth is for the water-cooled spindle winter must do a good measure of antifreeze, water freezing in the winter caused the pipe rupture is not uncommon, the engraving machine spindle will be frostbite.
Trapezoidal Toothed PU Timing Belt
Industrial synchronous belt applies the superior synthetic neoprene imported
from Japan as main raw material. It matches with multiple auxiliary materials with
various uses. Skeleton uses the superior glass fiber cord imported from japan. Tooth
face of the belt adopts nylon 66 high spandex for protection.
Synchronous belt drive is a novel drive mode that utilizes pulley gear meshing to
transfer motive power. It has accurate synchronous drive function. It needs no
lubrication without slip differential nor pollution and with little noise. Drive efficiency
reaches to 0.98. Speed ratio range can fulfill 1:10. Allowable linear speed can attain
50m/s. Drive efficiency ranges from several hundred watts to several kilowatts. It
suits multi-axial drive. It features as fine dynamic flex resistance, good anti-cracking
properties, superior ozone-proof performanca, sound heat-resistance and wearability etc.
