Which type of titanium alloy drill bit is good

Considering the material properties of titanium alloys. Should be selected for materials with weak affinity for the material. Hard alloys containing cobalt are definitely a good choice. Take the following measures: increase the top angle, grind the angle between the two edges to 135-140 degrees, and increase the back angle at the outer edge of the drill bit by 12-15 degrees. Repair the length of the small horizontal blade to 0. 08--0. 1. To reduce the axial force of drilling. Cobalt titanium alloy drilled well! If using a high-speed steel drill bit, the cutting speed is 7-12m/min, the feed rate is 0.05-0.2mm/r. If using hard alloy, v=25-60m/min, f=0.050.15m/r. When drilling shallow holes, the cutting fluid can be selected as electrolyte, which consists of approximately 7% -10% succinic acid, 7% -10% triethanolamine, and 7% -10% glycerol. Boric acid 7% -10%, sodium nitrite 3% -5%, the rest is water. When drilling deep holes, you can choose to add No. 30 mechanical oil to kerosene in a ratio of 3:1 or 3:2, or you can use sulfurized oil.

What are the types of drill bits commonly used in CNC machining centers?

Drill bits are generally divided into high-speed steel (HSS) and hard alloy (CARBIDE) according to the materials we commonly use. If the spindle accuracy of the machine tool is good and the power is high, alloy drills can be used to improve processing efficiency. If cost is considered, high-speed steel is more cost-effective, but the efficiency is relatively low. Compared to high-speed steel drill bits, alloy drills have an efficiency improvement of 1.5-3 times. The advantages of alloy drills are high hardness, wear resistance, and high temperature resistance. Disadvantages: Hard and brittle, prone to breakage if used improperly.

The difference between crown drill and shovel drill

Aesthetic characteristics: The top of the crown diamond is sharp and three-dimensional, making it more suitable for formal occasions or people who need to show their status, while the top of the shovel diamond is wide and flat, giving people a comfortable and natural feeling.

Which is better, Crown Diamond or U Diamond

Shape: The crown drill bit is hexagonal, with two side clamps and hexagonal brackets; And the U-drill is shaped like a U-shape, with a wider clamp plate that can significantly deepen the base position of the drill bit.
