Types ofdrillingin mining

This is a special breed of drilling machine mostly used to make deeper holes in various parts like spindles, barrels, connecting rods, and certain oil-well drilling equipment. This machine is also used by horizontal directional drilling contractors.

Titanium alloy has the characteristics of small specific gravity, high thermal strength, good thermal stability and corrosion resistance, and is widely used in aviation, aerospace, atomic energy and chemical industries. However, the material is difficult to cut, and it has been continuously explored to solve the technical problems of low processing efficiency and poor surface quality of titanium alloys. As advanced manufacturing technology has become more and more widely used in manufacturing, the use of ultra-high-speed cutting technology to cut titanium alloys has shown obvious advantages.

Every homeowner needs drilling tools and machines at some point. Let’s say that you plan to construct your dream house and to do massive construction like for a water source, you may need horizontal directional drilling contractors. Or if you are struggling with tight spaces, you can always check with directional boring contractors for a professional idea.

Ultra-high-speed cutting is a breakthrough in the understanding of traditional cutting. The cutting principle is different from conventional cutting. Ultra-high-speed cutting has its own characteristics and scope of application.

Ultra-high-speed cutting of titanium alloy improves its machining performance under the action of high strain rate response, thereby obtain high machining quality. The speed of ultra-high-speed cutting of titanium alloy is generally controlled in the range of 150-1000m/min. In addition to cutting speed, the key technology for ultra-high-speed cutting of titanium alloy also includes many factors such as tool spindle unit and feed unit manufacturing technology, machine tool support and auxiliary unit manufacturing technology, processing and testing technology. This article focuses on the tool materials that have a great impact on tool durability, machining efficiency and machining quality in the process of ultra-high-speed cutting of titanium alloy, in order to find the best match between the tool and the titanium alloy.

According to the processing characteristics of titanium alloy materials, the tool materials are required to have high deformation strength, high hardness, good toughness, good thermal hardness, good wear resistance and good heat dissipation properties.

During 221 BC, Qin Dynasty in China invented churn drills, which were used to drill large-diameter holes, in 1885, Isaac Singer built a steam-powered churn drill, based on the method that the Chinese used, and the greatest advancement in the drilling world was the invention of the electric drill.

These machines are for special purposes where the drill head consists of numerous spindles driven by a single motor. It is commonly used in manufacturing shops to drill multiple holes together at the same time. Its main purpose is to increase productivity and reduce operation time.

Steeldrilling type

Due to the high chemical affinity of titanium alloys, poor thermal conductivity and high strength, the cutting temperature is greatly increased and tool wear is intensified. Traditional processing methods are difficult to process.

A gang drill machine is a multi-column drilling machine in which numerous drill heads and columns are mounted on a single table. These are mainly used for drilling holes in a workpiece successively.

It was over 37,000 years ago when Home Sapiens realized what are the benefits of rotary tools. It was a sharp rock that, when rotated with hands, would drill a hole into another material. Around 10,000 years ago, people used bow drills as the first machine drills which were used in woodwork and stonework, but also in dentistry and to make fire.

In addition to the above, because titanium-containing tool materials are easily compatible with titanium alloys at high temperatures, titanium-containing tool materials must not be used.

For a long time, we have been exploring ways to improve the machinability of titanium alloys. Reasonable selection of tool materials and tool geometric parameters, reasonable formulation of cutting parameters, and the use of appropriate cutting fluids can all improve the machinability of difficult-to-machine materials to varying degrees. So far, there have been some methods. The commonly used methods include special heat treatment, heating cutting, introducing ultrasonic waves and vibration into the cutting area, etc. However, these methods generally have disadvantages such as low efficiency, high cost, and difficulty in guaranteeing processing quality. Here is an introduction to the advanced manufacturing process technology suitable for titanium alloy processing that can greatly improve production efficiency and product quality，it is ultra-high-speed cutting.

It can be seen that the main reason for the poor machinability of titanium alloy is due to the extremely high chemical affinity and poor thermal conductivity of titanium alloy. Experiments have shown that the greater the strength of the titanium alloy, the worse the machinability. The more the content of strengthening elements Al, Sn, Zr, Fe, Mo, Cr, etc. in the alloy, the higher the strength of the alloy and the worse the machinability. Impurities of oxygen, nitrogen, carbon, hydrogen, etc. in titanium produce interstitial solid solution, which makes the alloy stronger and has a greater impact on the machinability.

In this blog, let’s tackle the different types of drilling machines you need to know when you are planning to put up your own house:

Drilling typerig

This drilling machine is used for making holes in wood and metals. You can also perform various cutting operations such as boring, reaming, and tapping. This drilling machine is capable of drilling holes up to 12.5 mm in diameter in steel. It is widely used by woodworkers and manufacturing industries. This is also called a sensitive drilling machine due to the ability that this machine provides.

The use of ultra-high-speed cutting titanium alloy, which is difficult to machine, solves the problem of conventional cutting titanium alloy, which not only ensures the processing quality but also greatly improves the productivity, and has a good development prospect. Ultra-high-speed cutting technology is gradually mature for the processing of difficult-to-machine materials.

This is also known as the upright drilling machine. It is an advanced drill machine used for making 20mm to 40mm holes in metal and wood. It looks similar to a bench drill machine but it has a more powerful motor and more drilling capacity compared to a bench drill machine. This machine is primarily used by directional boring contractors and manufacturing industries.

A portable drilling machine is a small, hand-operated power drill, mainly used for making small holes up to 12mm in an object in any position. It can drill a hole through wood, plastics, metal, and concrete. Portable drill machines are used by woodworkers, house owners, plumbers, electricians, and industrial workers because of their small size.

On this machine, the drilling head is mounted to slide along a radial arm which can be rotated, raised, or lowered on a vertical pillar to adjust the position of the drill bit above the workpiece. It is mostly used in manufacturing machine shops to make a hole up to 80mm in diameter in large, heavy workpieces.
