Correct use of CNC drill includes what aspects?
The drill bit has a strong impact force when it is changed, so the drill bit device can adapt to any type of formation. The drilling speed of CNC drills has been greatly developed. How to use CNC drills correctly mainly includes the following aspects: Tip runout 1. Select the correct machine tool. CNC drills can be applied to CNC machine tools. Machining centers have high power and good steel performance, and the knife TIR should be guaranteed to be <0.02. The rocker drill, universal milling and other machine tools due to the power is small, the spindle accuracy is poor, easy to lead to the early collapse of the CNC drill bit, should try to avoid. 2. Choose the right hilt, spring clip

What are the basic components of a rig and what do they do?
The drilling rig is mainly composed of four major parts: rotary mechanism, feed mechanism, lifting mechanism and frame. The rotary drilling tool drives the drill bit to work at the bottom of the hole. Feeder mechanism: adjust the drilling pressure required for the drill bit to work at the bottom of the hole and control the feed speed; Lifting mechanism: used to complete the lifting of drilling tools, casing and ancillary work. Some drilling rigs also use the lifting mechanism to control the feed speed and feed pressure. Frame: according to the characteristics of the overall layout of the drilling rig, the above components are assembled into one or two whole, to achieve the requirements of compact structure, easy installation and disassembly.

Causes and treatment scheme of drill pipe sticking of rotary digging machine
Rotary drilling machine has the characteristics of large installed power, large output torque, large axial pressure, flexible, high construction efficiency, and environmental protection. With different drilling tools, it can be said that it is the most ideal machine for hole-forming work in construction projects. Also because of its high efficiency, environmental protection, high efficiency advantages, access to the construction unit. The problem of sticking in the process of work should be dealt with according to the depth of sticking, formation and other related factors, and corresponding countermeasures should be taken. The following is a specific look at the reasons for the sticking of the drill pipe of the rotary excavator and how to solve the sticking. 1, due to hole collapse or equipment itself caused by sticking drill, sediment thickness is large, to first clean the hole, and then use the drilling rig or auxiliary

What factors should be considered in the matching of drill pipe and drill bit?
Diameter difference is the primary factor we consider. Diameter difference refers to the difference between the diameter of drill pipe and the diameter of drill bit. As we all know, the diameter of drilling hole is caused by the diameter of drill bit. According to the requirements of drilling technology, the diameter of drill pipe should be smaller than that of drill bit. In the drilling process, it is beneficial to the discharge of cinder. Reasonable diameter difference can reduce the friction force of drill pipe.

What is the material of 42CRMO and 42CRMOA and what is the difference?
The A symbol after the grade of round steel indicates that the high-quality steel with low content of phosphorus and sulfur, 42CRMO and 42CRMOA have no difference in other aspects, and we know that the content of phosphorus and sulfur will seriously affect the performance and strength of steel. The one with A indicates high quality, less impurities and better performance.

Safety Operation Regulations for Impact Drill
The percussion drilling machine is an important drilling machine for the construction of cast-in-place pile foundation, which can adapt to various geological conditions, especially in the pebble layer, and the percussion drilling machine is more adaptable than other types of drilling machines. At the same time, with the impact drill hole, into the hole, the hole wall around the formation of a layer of dense soil layer, to stabilize the hole wall, improve the pile bearing capacity, have a certain role. Installation of 1. drilling rig 1. The site where the drilling rig is installed shall be flat and solid. If the drilling rig is installed in the soft stratum, the foundation shall be treated, and then sleepers shall be paved to ensure the stability of the drilling rig during operation, so as to avoid local subsidence of the drilling rig during drilling and affect the drilling.

Steps and process of drilling construction
Drilling engineering is a process of crushing rocks in the earth's crust according to a certain process with certain tools. The result of this project is drilling holes in the earth's crust. A borehole is a space of circular cross-section excavated from the surface like rock, generally of small diameter and great depth. The diameter of 25-500mm is called drilling; the diameter of 500mm or more is called drilling. The depth of drilling has been from several centimeters to several kilometers, and the current drilling depth has exceeded 10000 meters. The borehole includes an orifice, a hole bottom, and a hole wall. The orifice is the opening part of the borehole, that is, the place where the borehole intersects the ground or tunnel; the bottom of the hole is the deepest part of the borehole;

Yi Kuang Science and Technology | Teachers' Day | Don't Forget Teacher's En in September
Autumn September is another year of Teachers' Day. Looking back on the past, do you still remember the teachers who are persuasive beside you? They are so lovely that it is their teaching and severity that made us who we are today. Thank you for accommodating all our rebellious patience and teaching our teachers in the best years. It is because of your teaching that our life has a triumphant return.

About the installation and removal of the drill bit
The drill bit looks small, but its installation and use are still very exquisite. Familiar with it all know. Let's see what it's worth. First is the installation of the drill bit. Slowly lift the drill box, put the four legs of the drill box into the four holes of the drill rotary table, select the corresponding drill box core plate according to the specifications of the drill bit, lift the drill box core plate into the drill box, and then put the drill groove to be installed into the drill box corresponding to the convex point of the drill box core plate. Put the drill into the drill box, and the drill bit will be stuck in the rotary table core. Then screw the drill pipe with the connecting nut of the drill bit in turn. Again, the drill bit is disassembled. Lifting drill pipe (Attached
