CCMT2026 Preview After a Successful Jinan Machine Tool Exhibition

The 29th Jinan International Machine Tool Exhibition has successfully concluded. With rising raw material costs, more customers are showing strong interest in modular drilling systems as a cost-effective alternative. Ruilif Tools engaged with visitors across multiple industries and looks forward to meeting again at CCMT2026.

The difference between electric drills, impact drills, hammer drills, and pickaxes

A handheld electric drill simply relies on a motor to drive the transmission gear and increase the rotational force of the drill bit, allowing it to scrape through materials such as metal and wood.

Electric drills can be divided into three categories

Handheld electric drill: The power is the smallest, and its use is limited to drilling wood and as an electric screwdriver. Some handheld electric drills can be converted into specialized tools according to their purpose, and there are many uses and models available 2. Impact drill: There are two types of impact mechanisms for impact drills: dog tooth and ball bearing.

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.
