How To Improve The Service Life Of Diamond Bit
- May 07, 2018 -

When diamond bits are used for stone processing, machining parameters such as spindle speed and drilling speed have great influence on tool surface temperature. The surface temperature of tool increases with the increase of spindle speed and feed speed. 

The surface temperature of diamond bit increases with the increase of drilling time, and is directly proportional to drilling time. The influence of stone properties on the surface temperature of diamond bit is also great. When drilling granite under the same conditions, the surface temperature of the drill bit is 2 times that of marble and 5 times that of sandstone. Coolant should be used in dry drilling to prevent serious wear of diamond bit. Sintered diamond should be brazed or laser welded. It can ensure the high temperature resistance of the welded joint, so that the diamond head will not fall off earlier.
