Are you looking for cnc metal cutting machine for your workshop? Different kinds of cnc metal cutter machines are available on the market but have no idea where to start, please check the 2022 latest buyer guide here, undoubtedly you will find the best solution within your budget.
Types of Metal Cutting Machine
CNC plasma cutter is a kind of economic type cnc metal cutting machine, it is equipped with plasma power, eg, Hypertherm, Huayuan, etc. CNC plasma cutting machine can be used for different profiles, including steel plate, steel tube, channel steel, angle steel, beam profile, etc of stainless steel, carbon steel, electrical steel, galvanized steel, aluminum zinc plate, aluminum, aluminum alloy, titanium alloy, copper, brass, iron, etc.
Fiber laser cutting machine is a kind of high precision cnc metal cutting machine which takes fiber laser as light source, it is equipped with IPG or China Raycus fiber laser ranging from 500W to 12000W, Fiber laser cutting machine can be used for both plate and tube of different metal materials, including stainless steel, carbon steel, electrical steel, galvanized steel, aluminum zinc plate, aluminum, aluminum alloy, titanium alloy, copper, brass, iron, etc.
Comparision of Different CNC Metal Cutting Machines
Laser Cutting VS Plasma Cutting
Plasma cutting and laser cutting belong to heat cutting, plasma is more suitable for a thick plate having no high precision. However, with the development of the laser cutting machine, the high power of the laser cutting machine in recent years has ended, and the current cutting thickness has exceeded 100mm.
Plasma cutting machine is a plasma arc using high temperature and high heat to cutting the metal, the maximum disadvantage is that the cut is large, the cutting end surface is rough, and the precision is low. The laser cutting machine can do contactless cutting, the cutting is very small, high precision, small influencing area, smooth cutting section smooth, no need to process, saving processing and labor costs.
The product after the laser cutting machine is cut without secondary processing. Later use costs and labor costs have been reduced.
Plasma laser cutting machine is generally used for rough processing such as mechanical. Laser cutting machines are used in high-precision sheet metal processing, aerospace, intelligent equipment, construction machinery, transportation, electric equipment and other industries.
With the rapid development of industrialization, the accuracy requirements of metal workpiece cutting in various areas are increasing, and the advantages of laser cutting machines are increasingly obvious, and they are also applicable to more industry applications.
Oxyfuel Cutting VS Plasma Cutting
The flame cutting uses a high temperature flame to heat some point of the steel plate to the combustion point, and charge the high pressure oxygen to form a slit. The plasma arc cutting utilizes the heat of the high temperature plasma arc that causes the metal partial melting (and evaporation) at the workpiece incision and excludes the molten metal by the momentum of the high speed plasma to form a slit.
Flame cutting requires gas and oxygen, and three of the flames can be used in gas, propane, acetylene. Taking into account practicality and security, the current flame cut is mainly propane gas. The plasma cutting gas has argon, hydrogen, nitrogen, oxygen, air, water vapor, and some mixed gases.
The thickness of the flame cut is generally 6-200 mm, and the cutting thickness can reach about 350mm after special transformation. The thickness of the plasma cut is determined based on the size of the power supply to the cutting machine.
Flame cut is commonly used for cutting of ordinary steel sheets, while plasma cutting can be used in many types of metal sheets, such as stainless steel, aluminum plate, manganese steel plate, etc., Q235 sheet.
Compared to plasma cutting, the flame cutting machine cutting speed is slightly slow. Cutting 20 mm thick sheet, the flame cutting speed is about 450 mm / min per minute, the plasma cutting speed is about 1500 mm / min per minute.
The flame cut verticalness is better than the cutting of the plasma, and the flame cutting cut is perpendicular, and the plasma cutting surface has a certain inclinement.
The pre-input of flame cuts is small, there are many post-cost; the pre-input of plasma cut is large, and the later cost is relatively less. The difference between the cutting costs is mainly due to the need for the flame cut, mainly the need for gas, and plasma cut requires power and cutting.
CNC Metal Cutting Machine Price
There are many different kinds of cnc metal cutting machines and their price varies much, so it is hard to give the exact price. Generally, the price of cnc plasma cutter machine ranges from $4,000 to $50,000, whiles thbe price of fiber laser cutting machine ranges from $20,000 to $200,000, depending on actual model & configurations, such as driving system, control system, plasma & laser power, software, spare parts, etc, Also, some other charge & fees will have to be taken into consideration, including shipping costs, tax and customs clearance, etc.
