5-axis CNC machine for metal. Jig milling machines. Features of multi-axis milling machines

An increase in the number of working planes for milling equipment means additional features and a significant increase in functionality. All this can be fully attributed to 5-axis CNC metal milling machines, which are in high demand today. Their scope of application is quite wide, and the quality of processing of metal workpieces remains high, even when it comes to complex structural elements.

Technical parameters and purpose of 5-axis CNC milling machines

home distinctive feature A 5-axis CNC machine has a movable spindle head that can move simultaneously in two planes perpendicular to the surface being processed. Thus, the working tool can be moved in the up and down direction, positioned along or across the direction of the workpiece axis, or placed at an angle according to presets software.

The design of a 5-axis metal milling machine is similar to other equipment in this category. The workpiece is located and fixed on the working field, and the equipment is started thanks to servo drives. The choice in their favor is due to high accuracy their work and opportunities feedback, simplifying the management and control of equipment. One of the types of five-axis centers is a version with a spindle that can rotate simultaneously in five planes, mounted on a special rotating mechanism. This is the main difference between the machine and 4-axis milling models. An important advantage is also the presence of special sensors, whose tasks include monitoring the quality and accuracy of the operations performed.

Among the advantages of 5-axis CNC metal milling machines it is worth noting:

  • Ease of processing parts with a complex surface structure, where there are stiffening ribs, roundings, fillets and other protrusions and recesses. In addition, the equipment is effective when working with parts with complex shapes;
  • The ability to drill holes in different planes, which requires special precision of the machine;
  • The presence of a CNC unit simplifies the reinstallation of the machine and allows you to work without long downtime associated with moving the workpiece and readjusting equipment;
  • Five-coordinate milling machine can perform a full range of work operations without the need for additional equipment. This reduces the likelihood of defects and guarantees high accuracy finished products;
  • 5-axis metal milling machines can be used to process large parts for the needs of architecture, automotive and machine repair, shipbuilding, foundry, manufacturing household appliances and other areas.

Five-axis milling and processing of parts makes it possible to obtain a product from a solid workpiece, while eliminating the possibility of local overheating of the workpiece and thermal deformation of the product. The heat generated during the processing process is carried away from the processing zone along with the chips. Also, a product made from a single piece has better strength characteristics in comparison with products made by casting or stamping.

5 – coordinate milling is characterized by the ability to process complex products with a high degree of accuracy without the need for additional technological devices. In addition, a 5-axis CNC milling machine makes it possible to drill and boring all technological holes in one installation, thereby eliminating errors when basing in a technological device, which is important when the axis is positioned at an arbitrary angle. Moreover, the absence of reinstallation of the workpiece eliminates the loss of time for this operation, which has a positive effect on cost savings, which in turn is important during setup serial production parts, and the possibility of human factor or defects due to the fault of the operator disappears.

With 5-axis machining, it becomes possible to use short cutters, which allow achieving a greater degree of accuracy and more high speeds cutting, as well as obtain a better surface of the product. This approach combines several technological operations into one, thereby achieving a high degree of smoothness of the treated surface. This technique relevant for cutting polymerized parts made of composite materials and parts produced by vacuum forming.

Briefly about the machine and elements:

bed

The basis of the machine is a “column” shaped bed, made of cast iron elements, followed by machining. The use of cast iron makes it possible to obtain an almost “monolithic” frame that is not subject to deformation, which has a positive effect when working with particularly durable materials. All elements of the frame have high-quality milling for interfacing with each other and installation of structural elements, such as a profile rail, fastening elements for ball screws and stepper motors. The quality of milling in this case determines the accuracy of installation of all machine elements, their alignment and parallelism.

Table

The table is a massive plate cast from high-quality cast iron. The surface of the table is polished and processed to a “mirror” state. With “bad” casting, it is almost impossible to obtain such quality of subsequent processing, due to the presence of cavities, air chambers, etc. The table has additional milled grooves for fastening workpieces, vices, rotary-tilt mechanisms and other working equipment (T-slot).

Mechanics

The mechanics of a CNC machine deserve special attention. It all starts with a 20mm profile rail. The profile rail today is the best choice to build the basis of the mechanics of a high-quality CNC machine. The profile rails are installed in specially milled grooves on the frame, which ensures their absolute parallelism to each other along each axes, as well as the absence of a difference in height during installation. The rails are fastened with a large number of screws and additionally pressed to the frame with special hardened cylindrical “crackers”. This type of rail fastening design is difficult to implement on budget segment machines due to its high cost and increased requirements for material processing.
There are 4 linear motion bearings installed on each axle. To increase the rigidity of the moving elements, the bearings themselves are fixed at a certain distance from each other. On the one hand, this slightly increases the dimensions of the machine. On the other hand, it gives increased rigidity and the absence of backlash in all planes.
All moving parts of the CNC machine are driven by a 1605 ball screw, optionally with an additional nut and a “pre-tension system”. This system provides full compensation for ball screw play in the longitudinal plane, and also has better load distribution during movement, since the entire load is actually distributed over two independent nuts. The ball screws are attached to the frame using special support blocks. The entire machine is driven by NEMA 23 100mm stepper motors.

Control electronics

Stepper motor control is implemented using Leadshine DM556 discrete drivers. These drivers have their own built-in DSP processor, which controls the operation of the entire driver (current tracking, step crushing, anti-resonance algorithm). Leadshine is one of the leaders in the production of stepper motor drivers today. By default, the electronics unit is controlled by the computer via LPT. It is also possible to control the machine via USB or Ethernet.

Spindle

This machine has on board a high-quality spindle with a power of 1.5 kW liquid cooling. The control is carried out by a frequency converter, which allows you to adjust the speed of the cutting tool in the range of 6-24 thousand revolutions per minute.

Additional options (available upon request):

Spindle installation 2.2 kW

Tool sensor. Helps to accurately adjust the position of the cutting tool in height relative to the surface being processed.

Installation of servo stepper motors. A servo stepper drive differs from a classic drive in the presence of a feedback circuit with an encoder and flexible current control of motor operating modes. The use of servo stepper motors can improve machine productivity during intensive work by reducing the number of failures due to skipped steps. Also, the use of servo stepper motors allows you to work at higher speeds and accelerations compared to conventional stepper motors, which has a positive effect on processing speed.

Lubrication system. The machine can be equipped with a semi-automatic lubrication supply system. Oil is supplied to each linear bearing and to the ball screw nuts. Adjustment of the supply and quantity of supplied lubricant is regulated by a special dosing and distribution unit. The use of a lubrication system can significantly increase the working life of the moving elements of the machine and improve performance.

Computer. Finding a stable PC for CNC is not an easy task. The computer we offer has been tested and configured to work with the machine, and has on board all the programs necessary for operation.

Undoubted advantages of the five-coordinate center

The five-axis CNC-controlled center is operated on various enterprises, thanks to its wide functionality and the ability to work with the vast majority of materials. One center is capable of performing a series of complex operations that require high skill and precision in work. The operator sets computer program, allowing for filigree processing of parts and shaping the lining of their edges, which usually requires additional skill. The machine allows you to quickly and efficiently carry out complex mechanical processing of parts of a high level of complexity: shafts, sleeves, engine blades, dies, molds, etc. The centers allow you to operate various types cutters, drills and countersinks, spending a minimum of time and effort on reformatting the process. Carving and boring of parts made of titanium, cast iron and steel occurs dynamically and accurately, thanks to the power milling head and rigid structure

To speed up the productivity of modern factories, a 5-axis machine was developed; this installation operates on the basis of a spindle head, unique in its design.

Processing of workpieces can be carried out in 5 different planes, which eliminates the need for separate equipment to carry out such tasks.

general information

The main characteristic of the functionality of the coordinate installation of the master is the increased number of degrees of freedom to five.

It is allowed to process parts in the following planes:

  • the cutter can move along a vertical axis;
  • movement in a horizontal plane is allowed;
  • movement of the cutter at a set angle to the workpiece – 5th plane.

In terms of design features, the CNC coordinate milling machine is almost similar to its previous versions (four-plane and three-axis), but in terms of functionality, the addition of a fifth plane has allowed it to significantly outstrip them. An innovation for the innovative machine is its equipping with a servo drive, which ensures maximum operating accuracy.

The main difference is that the working tool is secured using a unique rotating mechanism. This feature is responsible for the inclination of the working cutter during milling.

Advantages of 5-axis installation

For many outdated models, it was necessary to select blanks that would correspond to a certain template shape; working with complex parts required significant preliminary preparation.

The jig milling machine is capable of working with the most complex blanks, which makes it a universal machine.

In addition to expanded versatility, a machine with software operating algorithms is characterized by the following advantages:

  • It is allowed to process products with non-removable complex elements: roundings, built-in stiffeners, various bosses.
  • The machine allows you to drill any number of holes located in different planes.
  • The operating time on the machine is significantly reduced due to the absence of stops, changes in the position of the workpiece, and additional fixations.
  • Working with numerical algorithms eliminates the human factor of intervention.
  • Additionally, there is no need to manually place the cutter in the “zero” position after finishing the work.

This type of machine is actively used when processing even large parts with complex shapes. The model is necessarily present in the staff of advertising organizations, automobile repair shops, is used in architectural areas, in the manufacture household appliances and in other areas.

Features of 5 coordinate technology

Carrying out work on a 5-axis milling installation begins with the creation of a main control algorithm. Thanks to the presence of CNC, this process is carried out automatically. Software for complex parts is created with the obligatory presence of a specialist.

After creating the software, the main stage begins - the implementation of mechanical work directly on the machine. The five-axis programming cycle looks like this:

  • A 3D model of the workpiece is created.
  • Often a pre-developed template is used or the installation is programmed from scratch.
  • For each stage of the processing process, a cutter trajectory is built, and both the rough version and the final finishing version are designed at once.
  • Loading the developed algorithm into a specific milling machine.

TO technological features The process of processing workpieces includes milling the contour of a part. To maintain efficiency, this function must be performed both with standard template workpieces and when working with complex parts.

Maximum accuracy is ensured thanks to pre-calculated trajectories of movement of the working cutter, as well as absolute fixation of the workpiece.

Subtleties of technological milling

Thanks to the single clamping of the workpiece, there is no need to stop the machine; the position of the working tool at each point of the trajectory is controlled under chip control. Only 5- and 4-axis machines are characterized by such precise calculations. During the milling process, these machines independently remove excess chips and remove them from the workspace.

Control of the angle of inclination of the cutter, the current position of the spindle - these parameters are controlled every second by the CNC, which underlies the most accurate processing of parts.

On the machine, it is easy to mill a part relative to a horizontal plane, cut holes vertically, and cut at any angle of the cutter. In addition, internal processing of any elements and parts of the workpiece is allowed.

The advanced functionality of this innovative model is used everywhere today. In any area, this installation allows you to significantly save time spent on work, and financial resources, while the quality of the final result only increases.
