The spindle end structure usually adopts the short cone flange type. The spindle shaft end is used to install fixtures and tools. The positioning accuracy of the fixtures and tools at the shaft end is required, the loading and unloading process is simple, and the overhang length of the spindle can be short. Due to long-term use of the belt-driven spindle of the 5 axis cnc machining service, the spindle box belt will make abnormal noises. This situation is mostly caused by belt problems.
(1). The belt tension connecting the main shaft to the servo motor is too tight: too tight can easily lead to increased belt wear, slipping, and abnormal noises.
(2). The belt tension of the spindle connected to the servo motor is too loose: If it is too loose, it will easily cause slipping during heavy cutting. When slipping, the belt spindle of the CNC machining center will make abnormal noises.
(3). The belt connecting the spindle to the servo motor is damaged: Under normal circumstances, if the CNC machining center operates for a long time, problems will inevitably occur. For example, the transmission belt will wear out after long-term use, which directly causes the belt to “wail”.
(4). The tooth profile of the transmission belt does not match the tooth profile of the servo motor and spindle: the transmission belt of the cnc copper machining center will definitely show some wear and tear after long-term use. Therefore, many customers will purchase and replace it by themselves in order to save costs. Later, it was discovered that the tooth profile of the transmission belt did not match the tooth profile of the servo motor and spindle, which would cause abnormal sounds during use. Therefore, professionals suggest that when purchasing a drive belt, customers must pay attention to whether the purchased drive belt is the same type as the disassembled and worn belt.
The mechanical structure of the main transmission system has been simplified to a great extent. Belt transmission and gear transmission have been eliminated. The spindle of the CNC machining center is directly driven by a built-in motor, thereby shortening the length of the main transmission chain to zero, allowing the machine tool to achieve The “the reasons for abnormal noise in the belt spindle of CNC machining center” process has been implemented.
