How to select and use belt
The Hangzhou Xihu grinding wheel factory to remind you: only reasonable selection, proper use of abrasive belt, and properly solve the belt used in various problems, play the abrasive belt grinding of superiority and the optimum grinding performance, in order to ensure the quality of workpiece.
1, reasonable selection of belt type
Different workpiece material and different workpiece shape in the selection of belt type is not the same, the selection of belt type mainly from four aspects of the matrix material, abrasive material, binder type and belt joint way to choose.
2, select the appropriate size
Only choose the appropriate granularity, in order to ensure the surface quality of workpiece and improve the service life of the belt. If the selection of abrasive grain size number is too small, there is no guarantee that the surface quality of the workpiece; if the selection of abrasive particle size is too large, belt in use easy to wrinkle and fracture, the service life of the belt reduced.
3, multi abrasive belt grinding process of selection of Liu Du
A workpiece if the multichannel abrasive belt grinding process, after use belt granularity ibid channel than most can only jump two granularities, and only in this way can play the efficiency of abrasive belt grinding, in order to ensure the surface quality of the workpiece size and shape of the workpiece.
4, multi process grinding grinding quantity distribution
Two processes: the distribution of the front and rear road is more than 85/15;
Three processes: the distribution of the front and rear road is more than 65/25/10;
Four processes: the distribution of the front and rear road is more than 50/30/12/8
5, the choice of the belt running direction
Consistent with the direction of using lap belt, to make the running direction of the belt with the back of the sand belt sign or belt in the use process is easy to premature fracture and influence the surface quality of the workpiece.
