Product Details

Our spindle has the advantages of compact structure, light weight, small inertia, small vibration, low noise, fast response and so on, and engraving machine spindle speed high, power, simplified machine design, easy to realize the spindle positioning.Engraving machine spindle bearing adopts high-speed bearing technology, wear-resistant and heat-resistant, life is several times the traditional bearing.
High-speed spindle is the core component of high-speed machine tool. It integrates the spindle of machine tool and the spindle of frequency conversion motor into one, namely, the stator and rotor of spindle motor are directly loaded into the spindle component. It is also known as built-in spindle.It has the advantages of compact structure, light weight, small inertia, good dynamic characteristics, and improve the dynamic balance of machine tools, avoid vibration and noise, in the ultra-high-speed machine tools have been widely used.According to the application of different machine tools it is divided into: drilling and milling spindle, machining center spindle, carving machine spindle, grinding machine spindle.With the rapid development and extensive application of high-speed machining technology, various industrial sectors, especially aerospace, aviation, automobile, motorcycle and die processing industries, are increasingly demanding high-speed, high-precision CNC machine tools.It is urgent to develop a higher quality high-speed spindle.

Engraving spindles types are very wide, such as: CNC engraving machine, laser engraving machine, woodworking carving machine, stone carving machine and so on.Conventional carving materials are: metal, non-metal, aluminum alloy, zirconia, acrylic, titanium alloy and so on.
