Milling of metal blanks is one of the main stages in the production of metal products, as well as structures for construction and mechanical engineering. Most often, when choosing processing equipment, preference is given to CNC horizontal milling machines, productive and multifunctional machines, thanks to which it is possible to guarantee excellent quality of output products, as well as ensure safety in the work shop.
Technical characteristics and features of horizontal CNC milling machines
The main feature that distinguishes the horizontal milling machine in the line of metalworking equipment, is horizontal arrangement spindle in which the tool is mounted. In this case, the working surface in relation to the cutting surface can be placed at any angle. Using CNC horizontal milling machining centers, a whole range of operations is performed: milling, boring, drilling, spot grinding of metal and other operations. The flexibility of the numerical control system settings makes it possible to quickly and accurately process complex, oversized products with a European and Japanese quality guarantee.
In order to easily perform full cycle finishing operations on one equipment without the need to repeatedly move the part to other types of machines; each piece of equipment is equipped with a wide range of metal-cutting tools. For example, cylindrical cutters are used for horizontal surfaces, and processing of vertical planes is carried out with end and disk cutters. The weight and dimensions of workpieces can vary widely: from small parts to large fragments of machines and other complex mechanisms.
The introduction of numerical control systems makes it possible to significantly simplify operator tasks and transform conventional machines into multifunctional ones. Thus, one person can control the operation of not one or two pieces of equipment, and the likelihood of defects is reduced to a minimum. There is no need for complex reconfiguration and time-consuming readjustment of equipment, since now it is put into operation thanks to a special computer program, which is activated by simply pressing a button. In this case, the output parameters of the part exactly correspond project documentation, and quality meets the requirements of any standards.
Depending on the dimensions, power, list of work performed and purpose, equipment is divided into household and industrial types. Recommendations for the use of one type or another can be gleaned from the technical documentation supplied with the equipment. Another option for classifying equipment can be its weight. According to this parameter, equipment is divided into 4 groups. The first includes machines weighing no more than 1 ton, the second - from 1 to 10 tons, the third - weighing up to 100 tons. The fourth group consists of models special purpose whose weight exceeds 100 tons. Each of the options described above differs in its functionality and can be equipped with any program control unit.

Design features of horizontal machines
The layout of equipment with a horizontal position involves placing both the work table and the spindle head in a single horizontal plane.
This design ensures optimal rigidity of the connection of machine elements, which has a positive effect on the quality of the entire range of operations associated with roughing and finishing processing of massive large-sized products. The movement of the work table is responsible for moving the workpiece along the X and Y axes, and the spindle head moves the workpiece along the Z axis. Often, machines of this type are equipped with a rotating work table, which allows processing of a fixed workpiece from four sides.
In order to reduce the processing cycle and optimize production process horizontal milling machines can be equipped automated system changing pallets, the number of which is two or more.
This principle of operation makes it possible to reduce the total cycle time for the workpiece installation operation, because large and heavy parts significantly complicate and prolong the production process.

Our range of milling machines is presented in the Milling Machines section.
Not a single one, both small and industrial enterprise The production of steel products and woodworking cannot be done without milling machines. The milling process is the first and key process in the processing of steel and wood workpieces.
The most popular among this category of units are horizontal milling machines.
1 Features of horizontal milling machine
A horizontal milling machine is one of the first units used for processing metal workpieces and various works on wood. They are used for milling, boring, grinding, and sometimes drilling. However, the equipment and technical specifications similar units are approximately the same.
The main feature of the horizontal console-milling device is the horizontal arrangement of the spindle. The working surface itself can move at different angles relative to the cutter.
The horizontal milling machine, like other industrial units, has not been spared by technological progress. In addition to the usual machines, where all the work with a milling cutter is performed by the operator, new units for metal and wood with CNC appeared(numerical program control).
Such a device does not require operator intervention in the workpiece processing process itself. A CNC machine operator must have skills not only in working with metal or wood, but also knowledge in the field computer technology and programs.
A 3D model of the future part is created on the computer, the path of the cutter and other technical characteristics are drawn, the program is transferred to the machine, and the machine performs all work on processing the workpiece under CNC control without human intervention.
1.1 Basic equipment
At its base, this device has a frame on which the remaining working elements of the unit are located. The frame must be as strong and vibration-resistant as possible, so it is made of cast iron or high-strength steel.
The following components and mechanisms are installed on the frame:
- transmission. With its help, the rotation speed of the cutter is adjusted;
- console. Moving device work surface cantilever milling unit along vertical guides;
- desktop This device is equipped with clamping mechanisms or a vice for installing metal or wood workpieces. The work table of a cantilever milling machine is made in such a way that it can be moved in three directions: longitudinally along the slide guides; transversely by moving the slides themselves along the console guides; vertically, by moving the console-support mechanism along the frame guides;
- spindle. The main rotating device on which there is a mandrel for fixing cutters;
- trunk. The housing element on which the suspension with the spindle is attached;
- the milling mandrel is attached to the end of the spindle;
- engine. Industrial units are equipped with a three-phase motor, while household units are equipped with a two-phase motor. The engine power must be at least 1200-1500 W, to provide desired speed spindle rotation. A horizontal milling machine for metal or wood must maintain a cutter speed of 400 to 4500 rpm;
- additional equipment. In addition to the equipment listed above, the machines can be additionally equipped with CNC boards, chip ejectors, and magnetic tables for clampless fastening of workpieces.
1.2 Cutters
It is very important that a horizontal milling machine allows for quick replacement of cutters, since each cutting tool performs only its narrow-profile function. In addition, the attachment of the cutter should be as rigid as possible.
Any vibrations or bending of the cutting tool will lead to damage to cutters and workpieces when working on metal or wood. To securely fasten the cutter, the mandrel must be mounted on a suspension. The fastening itself is done using rings and nuts.
- The milling machine 6р81, 6р82 and its other analogues process horizontal surfaces using a cylindrical cutter;
- The device performs vertical work on metal or wood using end or disk cutters;
- combined processing requires changing several cutting tools with different functionality.
To increase the accuracy of milling work on metal or wood, a 6m82 milling machine It is recommended to equip it with a CNC board.
2 Machine types
Note that cantilever milling machines can be used for both household and professional use. They allow processing workpieces weighing from a few grams to thousands of kilograms.
Based on the size of the equipment, cantilever milling machines for metal or wood are divided into three groups:
- first group – light equipment weighing up to 1 ton;
- the second group is medium-sized equipment whose weight ranges from 1 to 10 tons;
- the third group - heavy units, weighing from 10 to 100 tons;
- There is also a fourth group - special machines whose weight exceeds 100 tons.
Any of the above units can be equipped with CNC.
The second criterion for dividing cantilever-milling units into groups is the control method. The machine control can be manual, semi-automatic or automatic using CNC.
- Machines with manual control require full control from the milling machine. He must install the workpiece, turn on the machine, bring in the cutting tool, adjust the trajectory and speed of the cutter, turn off the machine, and remove the part.
- Semi-automatic devices are configured to perform a specific cyclic task. The operator places the workpiece and starts the machine. The unit independently performs the programmed cycle and stops. The worker must then remove the part from the clamp and turn off the machine.
- Automatic units are equipped with CNC. In this case, A milling operator must be able to use not so much a machine as a computer and related programs. His task is to create a 3D model of the future part and draw the trajectory of the cutter, as well as other technical parameters of the machine. After transferring the numerical code to the machine, installing the workpiece and starting the unit, it will independently perform all the work. The operator's task is only to observe his work.
2.1 Operating rules for horizontal milling units
IN technical passport For any model of a cantilever milling machine, the rules for its installation, assembly, and operating features are prescribed. However, there are also general rules relating to any type of manual or CNC equipment. These requirements relate to the organization of the technical process and compliance by workers with safety rules.
The first task of a production engineer is to correctly select and prepare the installation site for the unit. It is selected depending on the dimensions and weight of the machine. It is also important to have vibration compensation for the unit on the side of the platform on which it is installed. The floor under the machine must be rigid; it is usually poured from durable reinforced concrete. Additionally, supports with compensation cushions can be installed.
Assembly and maintenance any unit must be carried out by a specialist. Operation of the unit with the slightest technical malfunction is strictly prohibited!
Also, the general operational requirements of horizontal milling machines include:
- Horizontal milling machine operator must carry out work in special clothing. The use of protective gloves or mittens is strictly prohibited.
- The milling operator must carry out all work on the machine wearing safety glasses.
- If the workpiece for milling weighs more than 20 kg, it is installed on the work table using lifting mechanisms.
- If abnormal vibration or oscillation occurs, the machine must be stopped immediately. Most often, such a malfunction is caused by improper installation of the cutter.
- Often, on devices of horizontal milling type, an additional chip ejector is installed. But even in this case, the worker must thoroughly clean the machine from chips and dust.
