Tangential knife

Tangential knife

For turning the blade as a drive, a stepper motor is used. The use of such a knife allows cutting various materials: plastics, leather, fabric, or corrugated cardboard.
The blade oscillation mode (a vibroknife) makes it possible to effectively cut honeycomb materials, rubber, and other soft materials


Helical racks

Helical racks

Helical racks mounted to the X and Y axes increase the accuracy and the quality of processing of parts and reduce noise when moving the beam and the carriage.


Vacuum hold-down

Vacuum hold-down

The vacuum hold-down system is the most progressive method of fixing the material being processed to the working surface of milling engraving machines. The vacuum hold-down system includes a vacuum table, a system of air ducts and valves, and a vacuum pump. The vacuum hold-down system can be used in zones depending on the size of the material being processed.


Automatic tool change system

Automatic tool change system

This option allows for a significant speeding up of the process of material processing with the use of several tools, helps increase the automation of the machine, and simplifies the adjustment of the tool along the length. The automatic tool change system is only installed on the equipment with HSD spindles with a pneumatic gripper. 


Tool-length-measuring probe

Tool-length-measuring probe

The sensor allows for quick and accurate measurement of the length of the cutter.  The operator only needs to launch this function from the touch screen monitor, after which the machine measures the length of the cutter automatically. The received data are automatically taken into account when performing tasks, which excludes damage to the working surface of the machine.


Spindles

Spindles

VOLTER equipment uses air-cooled spindles with a power ranging from 2 to 11 kW, which are manufactured by HSD (Italy). For all spindles, the ER32 collets are used. Spindles with a mechanical clamping tool or with a pneumatic gripper can be installed. The maximum speed is 24,000 rpm. 


Working area dimensions

Working area dimensions

Standard working area dimensions: 1,640x1,610 mm, 2,200x1,610 mm, 3,200x1,610 mm, 3,200x2,150 mm, 4,200x1,610 mm, 4,200x2,150 mm, 6,200x1,610 mm, 6,200x2,150 mm. You can order a machine with non-standard working area dimensions.


IP camera

IP camera

This option allows cutting out the printed image along its outline. When preparing a file for printing, marks (circles of black color with a diameter of 5–8 mm) located behind the outline of the image to be cut are added to the file. The printed image is placed on the machine, and the camera reads the mark offsets after the job is started. Special software used by the machine introduces corrections to the cutting program, which allows cutting out the printed image accurately along its outline regardless of the geometric distortions that have occurred during printing and offsetting the printed image on the machine.


Tool lubrication and cooling system

Tool lubrication and cooling system

The system carries out a dosed supply of a lubricating emulsion or an air stream to the cutting zone.  Continuous supply of a lubricant (in the form of an oil mist) or compressed air allows maximizing the service life of the tool, improving the quality of processing, and increasing the material processing speed.  The lubrication system is operated after the connection of an external air compressor with a working pressure of at least 6 atm.


Installation of two spindles

Installation of two spindles

This option allows the material to be processed with two cutters without operator intervention. Each spindle has its own Z axis drive. To preserve the dimensions of the working field, the portal beam has increased radii. This option is especially relevant for the processing of aluminum composite panels.  In this case, a V-shaped milling cutter is installed in one spindle for milling for bending, and a milling cutter for cutting the material is installed in another spindle. This configuration allows the processing of sheets of composite panels without operator intervention to replace the tool.


Vane rotating knife

Vane rotating knife

This is an efficient and reliable device for cutting polymeric materials and corrugated cardboard. Its main application is the cutting out of shapes of corrugated cardboard, sheet vinyl, and other polymer sheets along an outline. The principle of operation of vane-type knives lies in the fact that the device cutter is installed into the free-rotation rotary mechanism due to the special shape of its cutting edge and the displacement of its tip relative to the axis of rotation of the cutter, which is rotated by the cutting edge in the direction of the tool movement due to the material resistance.


All-purpose mounting attachment (chip removal + material hold-down)

All-purpose mounting attachment (chip removal + material hold-down)

This option serves to create additional pressure on the material in the processing area so as to ensure the best possible pressure of the material against the surface of the working table. 
It is recommended for the processing of warped or curved sheets of a rigid material (for example, aluminum) and for the processing of thin and soft materials. 
In addition, this attachment can be used to remove chips and dust.


Chip conveyor mounting attachment

Chip conveyor mounting attachment

This option serves to remove the processing waste from the cutting area. A special chamber mounted to the slide plate of the support shields the cutting area and prevents the spread of chips and dust from the processing area; the processing waste is removed from the chamber through the air branch pipe by a chip pan, which must be installed permanently.  The application of this option promotes faster processing (there is no need for manual cleaning of the processed sheet and machine mechanisms) and improving the environmental situation at the milling and engraving facilities.
