Nowadays, road milling machine is widely used and the demand is huge. As an indispensable part of road milling machine, road milling bit has certain requirements for its use method and working environment. Only reasonable use of road milling bit can extend the service life of road milling machinery. So how to use road milling bit?
Here is the content list:
How to install road milling bits?
How to maintain road milling bits?
What problems may occur when using road milling bits?
Slowly lift the box of the road milling bit, and put the four legs of the box of the road milling bit into the four holes of the drill turntable. According to the specifications of the road milling bit, select the corresponding drill box core plate, and lift the drill box core plate into the drill box body. Then, the groove of the road milling bit to be installed corresponds to the protruding tip of the core plate of the drill box, and the road milling bit is placed in the drill box, and the drill bit is clamped in the center of the turntable. Then screw on the road milling bit connecting nut drill rod in turn.
1. After using the road milling bit, check immediately for damage, passivation, etc. If any, it should be ground and trimmed immediately.
2. When storing, the road milling bit should be seated. It saves time to search for the drill bit when it is used later.
3. When drilling a through-hole, when the road milling bit is about to drill through, the torque is maximum. Therefore, lighter pressure is required to advance slowly to avoid the road milling bit from twisting due to excessive force.
4. The center point must be drilled before drilling. Its purpose is to accommodate the static point and prevent the drill bit from bottoming out.
5. When drilling, make full use of cutting and pay attention to chip removal.
6. When drilling cross holes, drill large diameter holes first and then drill small diameter holes.
1. When the road milling bit is drilled, it may be broken or stopped suddenly, which may be caused by too fast cutting, sharpening, or sharp heat during drilling.
2. Drilling cracks the center of the road milling bit, which may be caused by too small drill lip clearance angle, too fast feed, passivation of the road milling bit, too much pressure, lack of cooling, and poor clamping of the drill or workpiece.
3. The road milling bit breaks during drilling. It may be caused by too small drill lip clearance angle or too high drilling speed, large feed or road milling bit has been dulled and continues to press cutting.
4. The drill lip and the cutting edge are broken, which may be caused by too fast feed or too small clearance angle of the drill lip.
5. When drilling, only one chip is discharged, which may be caused by the unequal length of the two cutting edges or the unequal half-angle of the drill tip.
6. The squeaking sound when drilling may be caused by the hole is not straight or the road milling bit is dull.
7. Abnormal changes in the properties of chips during drilling may be caused by the cut edges that have been passivated or broken.
It is the responsibility of each manufacturer to produce industrial road milling bit that meets the standards, to ensure the healthy development of the road milling bit market.
