Housings for electronic devices/microwaves, heat sinks/radiators for electronics, as a rule, contain small structural elements: threads for fastening printed circuit boards, holes for connectors, grooves for laying and fixing sealing gaskets, etc. Universal machining centers are often not able to quickly cope with milling small elements of electronic devices due to the low rotation speed of the cutting tool, so high-speed 3D CNC milling is optimal.
High-speed 3D CNC milling of aluminum is a modern, dynamically developing area of metal cutting. With this type of processing, classical formulas for calculating cutting forces do not work, because the speed of intermolecular rupture of metal differs significantly from the speed of metal separation during standard “power” milling.
During high-speed milling of aluminum, the importance of removing heat and chips from the cutting zone increases, so cooling is carried out using technical alcohol supplied to the cutting zone using compressed air. This provides additional advantages in the absence of the need to wash parts after milling - aluminum and copper housings for electronic devices / microwaves, heat sinks / radiators for electronics, come out literally shiny.
Also, one of the undeniable advantages of high-speed milling is the cleanliness of the processed surfaces. High-speed 3D CNC milling allows, without grinding, to obtain the required parameters of roughness and flatness of heat-removing surfaces of REA / microwave housings and heat sinks / radiators of radio-electronic devices.
High-speed milling requires the purchase of special, expensive carbide tools. Unfortunately, “standard” cutters are not suitable for this type of processing, and this significantly narrows the choice of cutting tools.
Another advantage over “standard” milling is that “drilling” holes for various diameters of blind or through threads can be done with one carbide milling cutter at high speed without the need to change the cutting tool. This significantly reduces processing time and, as a result, becomes cheaper.
Mechanical threading in instrument housings for electronic devices/microwaves often leads to breakage of the taps inside the almost finished part. This increases the cost of parts for the Buyer, because The supplier has to include additional costs for technological stock into the cost of manufacturing the batch. Also, a negative factor in metalworking threading in aluminum, copper and plastic is the low quality of the resulting threads: lack of perpendicularity to the main surface, “jamming” of the first turns of the threads being cut due to the need to repeatedly screw in and turn out the taps.
High-speed 3D CNC milling of aluminum allows you to avoid this problem: thread milling is carried out with special carbide cutters moving along a spiral path.
Another serious problem in the manufacture of “species” housings of REA / microwave units is manual machining of chamfers, burrs and sharp edges, because It is very difficult to achieve high quality of processed surfaces of aluminum parts manually.
High-speed 3D CNC milling of aluminum, copper and plastic allows you to remove chamfers, burrs and sharp edges with high speed, accuracy and quality using special carbide countersinks. This type of milling processing significantly increases the consumer qualities of manufactured products and reduces the risk of specific parts becoming defective.
Our company provides services in the field of milling aluminum and non-ferrous metals to order of any complexity. We specialize in the manufacture of housings for electronic equipment, including sealed and waterproof IP69 (for remotely controlled uninhabited underwater vehicles).
Housings for radio-electronic equipment (REA) and control and measuring instruments, and automation (instrumentation and automation) are widely used in all sectors of industry and the national economy. This is due to the fact that electrical and radio-electronic devices need protection from mechanical, physical and chemical influences for normal functioning. It should also be noted that aluminum cases for electronic equipment and instrumentation are very durable, so they effectively protect the equipment located in them from accidental damage. The durability of such cases is also high, since, properly treated, they are not subject to atmospheric or chemical corrosion. This allows the use of aluminum (aluminum alloy) housings in industry. The production of aluminum cases is an important segment of our company's activities. Absolutely any modern production cannot do without housings for electronic equipment or instrumentation and automation, made on the basis of aluminum and other non-ferrous metals.
Metal milling is a technology for producing various parts by cutting using a milling cutter - a special cutting tool.
Milling processing is carried out with high quality and within the specified time frame of the customer. The company has the latest special equipment that will allow you to perform any type of milling work. Your order will be fulfilled by highly qualified specialists, thanks to whose skill it is possible to produce the necessary metal blanks with minimal material costs for the customer. They will be able to process shaped, cylindrical, end, and conical surfaces.
Metal milling, performed on milling machines, allows the processing of horizontal, vertical and inclined surfaces, as well as shaped surfaces and grooves.
Milling work, which is a specialization of our company, includes a complex of technological processes for processing metal workpieces by cutting. Milling work is carried out to process the external and internal surfaces of parts with the ability to process horizontal, vertical and inclined surfaces on milling machines. Milling work is performed with a certain speed, feed and depth of cut, while the feed speed is limited by the heat resistance of the cutter material, and the choice of depth and feed depends on the strength of the cutting tool. Depending on the work performed, universal, horizontal, vertical, longitudinal, rotary, drum and other types of milling machines are used.
The most effective metalworking methods, in addition to turning, include milling. The milling method can be used to process unhardened steels, non-ferrous metals and alloys, although in some cases it is also possible to process hardened steels. A feature of milling performed using a multi-edged cutting tool (cutter) is the intermittency of cutting by each tooth of the tool. Milling involves cutting only on a certain part of the workpiece with which the cutter teeth come into contact.
When milling, the geometry of the workpiece directly depends on the shape of the tool, therefore, depending on the workpiece, different types of cutters are used. Climb milling is used to obtain clean surfaces, and up milling is used to increase productivity. Rough milling is performed using cutters with large insert pitches and involves a large depth of cut, while finishing reduces both the depth and the processing speed.
Milling using multi-blade metal-cutting tools is one of the most common metalworking technologies. Milling as a technological process of metal cutting is carried out using cutters that allow horizontal, vertical and inclined milling of surfaces.
This technology is used for end, face, peripheral and shaped milling of parts. End milling is used for grooves, undercuts and grooves (including through grooves), face milling is used for machining large surfaces, and form milling is used for machining profiles (for example, gears). Milling, like turning, is performed at different speeds, feeds and depths of cut with the ability to change these parameters for specific parts.
Modern high-precision milling equipment from DATRON (Germany) allows us to process materials such as aluminum, copper and their alloys, plastic and textolite.YCM also presented a turning and milling machining center YCM-GT-250MA.
The development of control programs for CNC machines is carried out using the Mastercam geometric modeling and software processing system for CNC machines.
