The emergence of the belt sander has replaced the traditional manual grinding steps, which is simply a lazy gospel. At the same time, because it can bring higher work efficiency, it is favored by users. It has the following characteristics:
1) Abrasive belt grinding is a kind of elastic grinding, which is a composite processing technology with various functions such as grinding, grinding and polishing.
2) The abrasive particles on the abrasive belt have stronger cutting ability than those on the grinding wheel, so the grinding efficiency is very high.
3) The surface quality of the abrasive belt grinding workpiece is high. In addition to various functions such as grinding, grinding, polishing, etc., it is also because:
A. Compared with grinding wheel grinding, the temperature of abrasive belt grinding is lower, and the surface of the workpiece is not easy to be burned.
The abrasive belt grinding system has low vibration and good stability. The elastic grinding effect of the abrasive belt can greatly reduce or absorb the vibration and shock generated during the grinding process.
B. The grinding speed is stable, and the abrasive belt drive wheel is not ground like the grinding wheel, the diameter is small, and the speed is slow.
4) High precision abrasive belt grinding, abrasive belt grinding has entered the ranks of precision machining and ultra-precision machining, and the Z high precision has reached below 0.1mm.
5) The cost of abrasive belt grinding is low. This is mainly reflected in:
A. The abrasive belt grinding equipment is simple, mainly due to the light weight of the abrasive belt, the small grinding force, the small vibration during the grinding process, and the rigidity and strength requirements of the machine are much lower than those of the grinding wheel grinder.
B. The abrasive belt grinding is easy to operate and has less auxiliary time. All of this can be done in a very short time, from changing the adjustment sand to clamping the workpiece being machined.
C. The abrasive belt grinding ratio is high, the machine tool power utilization rate is high, and the cutting efficiency is high. Cutting the same weight or volume of material requires less tools, less effort, and less time.
6) Belt grinding is very safe, with low noise, less dust, easy control and good environmental benefits.
7) The abrasive belt grinding process has great flexibility and strong adaptability. details as follows:
Belt grinding can be conveniently used for grinding flat, internal, external and complex surfaces.
C. The choice of the base material, abrasive and binder of the abrasive belt is wide, which can meet the needs of various uses.
8) The application range of abrasive belt grinding is extremely wide. The superior grinding performance and flexible process characteristics of belt grinding determine its wide application range. From daily life to industrial production, abrasive belts cover almost all fields.
