用车床加工成的玻璃钻头(附图),可用来加工φ10以上的通孔,也可加工较厚的普通平板玻璃,但不能加工半深孔。加工时,可把这种钻头装在小台钻或摇臂钻床上加工。根据生产需要,也可制造专用设备。这种钻头是用潮湿金刚砂配合钻孔的。因此,专用设备的钻杆最好是上下相通的,以便金刚砂流入钻头空腔内。这种玻璃钻头,对一般小厂很适用。在使用玻璃钻头时,一定要做好操
Lathe processed into glass drill (with photos), can be used to process more than φ10 through-hole, but also thicker ordinary flat glass processing, but can not be processed half-deep hole. Processing, the drill can be installed in a small bench drill or radial drilling machine processing. According to production needs, but also create special equipment. This bit is drilled with damp emery. Therefore, it is preferable that the drill pipe of the special equipment be connected up and down so that the corundum flows into the drill cavity. This glass drill, is suitable for small factories in general. When using the glass drill, be sure to do a good job
