Can you cutting titanium with angle grinder? 10 ways to cut titanium
Titanium and its alloys have the characteristics of high strength, light weight, strong corrosion resistance, etc., and are widely used in aerospace, medical and automotive industries. However, titanium has poor thermal conductivity and high hardness, which also makes titanium prone to work hardening during machining, making it more difficult to cut than other metals.
At present, there are many different methods for cutting titanium alloys, such as cutting titanium with an angle grinder, plasma cutting titanium, laser cutting titanium, turning titanium, milling titanium, etc. These methods will be introduced in detail below. Through the introduction, you can choose the appropriate method for cutting titanium.
⏩ Is titanium metal easy to cut?
Titanium and titanium alloys are sensitive to temperature during processing, and are considered to be one of the more difficult metal materials to process. For the cutting of titanium alloys, cold sawing, laser cutting, or choosing appropriate tools and coolants during machining can be smoothly cut.
⏩ Why is titanium alloy particularly difficult to cut?
There are 6 reasons why titanium alloys are difficult to cut, namely:
Short contact length between the tool and the chip
Poor thermal conductivity
High chemical affinity
Low elastic modulus
Titanium chips are flammable
Severe cold hardening phenomenon
⏩ Can you cutting titanium with angle grinder?
Angle grinders are a commonly used power tool that is mainly used for grinding, cutting and polishing metal materials. However, when trying to use an angle grinder to cut titanium alloys, we need to consider the following key factors. Can the type and material of the blade you choose effectively cope with the hardness of titanium alloys? The heat generated during the cutting process may cause the cutting tool to wear out quickly.
In order to safely and effectively use an angle grinder to cut titanium, you should use a tungsten carbide grinding wheel with a special coating, which can provide better wear resistance and cutting efficiency.
In addition, during the cutting process, a coolant such as water or oil metal cutting coolant should be used to reduce heat and extend the service life of the tool.
⏩ Introduction to 10 methods of cutting titanium
Manual cutting of titanium plates
Manual cutting of titanium plates is possible, but it is very difficult and takes a lot of time, but the biggest advantage is that it saves money.
Sawing titanium:
Usually, carbide saw blades are used. The surface after cutting is clean and smooth. Sawing is suitable for cutting titanium tubes, but it should be noted that titanium chips are easy to catch fire and should be cleaned in time.
Cutting Titanium with Angle Grinder:
An angle grinder is a handheld power tool that can be used to cut metal. This can be done using an angle grinder with a cutting disc. An angle grinder with a masonry cutting disc is the best.
When cutting titanium with angle grinder,, a special titanium cutting disc is required, and the cutting speed should be low. At the same time, water or oil is continuously poured to cool the titanium and cutting disc to prevent overheating of the titanium and the cutting disc.
This cutting method is suitable for small-scale cutting work. Operators need to pay attention to safety and wear protective equipment.
Turning titanium:
Processing titanium on a lathe is to rotate the titanium material and then gradually cut it with a special tool.
It is often used to process shaft parts because these parts are suitable for turning. However, cutting titanium metal on a lathe requires a lot of patience because it is only effective at low speeds. Once the speed is too fast, it is easy to increase the wear of the tool.
Milling titanium
Milling titanium is not as simple as milling aluminum. The high hardness of titanium will cause the tool to wear quickly. Just like turning titanium, it needs to be cut at a low speed. Carbide or coated tools can be used, and coolant should be sprayed continuously to reduce the heat of the metal.
Plasma cutting of titanium:
Plasma cutting machines are usually used to cut metals through high-temperature plasma arcs. This is a more feasible solution and is often used to cut titanium plates. It is efficient and low-cost. However, there is a disadvantage that the edges of the cut titanium metal will produce an oxide layer, which requires subsequent grinding.
Laser cutting of titanium:
This method uses a high-energy laser beam to irradiate the surface of the material, causing the material to melt and vaporize rapidly. At the same time, these high-speed airflows can also blow away the molten titanium chips, so that the surface becomes cleaner, which is very suitable for difficult-to-process metals such as titanium.
Water jet cutting:
Water jet cutting is a method of cutting by flushing the material with high-pressure water. Abrasives can also be added to achieve faster cutting.
Compared with traditional mechanical cutting, water jet cutting has the advantages of no heat-affected zone, smooth cut without oxidation, environmental protection and no pollution.
Although water jet cutting may be slightly inferior to plasma cutting and laser cutting in terms of speed, its advantages are more obvious than the first two processes when processing complex shapes and thick plate materials.
Electric spark wire cutting (EDM)
Electro-spark wire cutting is an advanced titanium metal cutting technology. It is particularly useful for difficult-to-process metal materials. It is different from other processes in that it uses high-speed electron flow to accurately remove materials. The advantage of this method is that it can be used for special-shaped parts and is not limited by hardness. The disadvantages are slow speed, regular replacement of electrode wires, and high cost.
CNC machining center cutting titanium
Computer numerical control machining can also be used to process titanium. It can be easily and safely programmed to cut titanium plates or process titanium parts. Xavier's operators are proficient in CNC programming and CNC machining technology to ensure that titanium parts are cut at accurate angles and speeds. CNC machining often does not require too much labor cost to complete high-quality parts processing.
Here is a titanium alloy cutting guide, which details 10 titanium alloy cutting solutions, including cutting titanium with angle grinder, cutting titanium with a water jet, etc., which will give you the answers you want to know.
⏩ The most suitable titanium cutting tools and equipment
Titanium and titanium alloy tubes should be cut mechanically (manual saws, sawing machines, lathes, etc.), and low cutting speed is the best. Processing hard materials such as titanium metal takes a long time.
If you are too impatient to increase the processing speed, the high temperature generated during cutting will harden the surface of the tube;
In addition, when titanium tubes are cut or repaired with an angle grinder, special grinding discs should be used; flame cutting should not be used, and water jet cutting is a better solution. Before the tube is processed and cut, the cutting part must be marked to ensure that the correct size of the tube is obtained.
⏩ FAQ: Comparison of difficult-to-process metals
Titanium alloys and stainless steel are two common metals in mechanical processing. So many people have questions about which is more difficult to cut, stainless steel or titanium alloy.
What is the difference between titanium alloy and stainless steel?
 |
| Titanium alloy plate |
 |
| Stainless steel sheet |
First of all, we all know that titanium alloy and stainless steel are two different metals, and the categories are different. The main difference is mainly reflected in the material and performance: titanium alloy is based on titanium and other elements are added. It is stronger, lighter, and has excellent corrosion resistance and high temperature resistance. Stainless steel is mainly composed of iron, chromium, etc., which is corrosion-resistant and has a lower cost.
In terms of processing difficulty, both titanium alloy and stainless steel are prone to work hardening, which also troubles many mechanics. In a comprehensive comparison, titanium alloy is more difficult to process because of its higher hardness and greater viscosity.
If you want to say which of these two metals is better, titanium alloy is more expensive than stainless steel in terms of price. Both titanium alloy and stainless steel are very good in performance, but the overall practicality of titanium alloy is higher.
