Design advantages

Unlike conventional 3-axis milling of a part, 5-axis machining allows you to machine a product from five sides, without additional operations for rearranging the part on the desktop.

This allows you to obtain products of complex shape with high accuracy and processing speed.

TPA control desk (Italy) - includes 2 modules: Tra WSCM - machine control and Tpa Cad - modeling, editing, creating control programs.

Additional touch-sensitive portable control panel for convenient control of the machine.

The machine is equipped with a modern powerful electrospindle 12 kW from the Italian manufacturer HSD, "ES779". This is the first spindle with its own intelligence, which independently diagnoses its work and sends information to the machine control system in real time. This allows you to accurately control the operating modes of the spindle and comply with the required technology for processing the part, which ensures stable operation of the machine, high quality processing and extends the life of the tool.

The milling unit is mounted on the “Z” carriage and has a pneumatic start. Movement occurs on 75 mm wide linear guides and preloaded linear bearings capable of withstanding equal loads in 4 directions.

This solution, together with the large distance between the Z-axis guides and the optimal position of the lead screw (in the center position), guarantees high milling precision. Two sensors ensure the correct grip of the tool.

The electrospindle is equipped with a cone cleaning system by blowing air for a safe grip and has the following features:

• Rigid construction.
• liquid cooling.
• Cone clamps HSK-F63.
• Rotation speed up to 24000 rpm.
• Rotation along the “C” axis (0 – +720°).
• Rotation along the “A” axis (-20° – +200°).
• Automatic tool change.
• Tool control system.
• Spindle diagnostics are visualized on the control stand.
• Overload protection.

The 22-station automatic tool changer for the HSK-F63 chuck will provide the machine with the necessary stock of used milling cutters and allow you to perform complex operations using more tools. The magazine is equipped with a servo drive, which allows you to change the tool with high accuracy and speed. The maximum permissible weight of the tool is 6 kg.

Additional 16-position automatic tool change magazine for HSK-F63 chuck.

Optional 5-station linear magazine for HSK-F63 chuck for quick access to specialty tools.

1 post blade magazine for saw blades up to 250 mm.

The drilling and filler group has (12 vertical + 8 horizontal spindles + 1 grooving saw).

Technical characteristics of the drilling and filler group:

• Center-to-center distance between spindles 32 mm.
• Motor power 2.2 kW.
• Rotation speed 4600 rpm.
• Grooving saw 125 mm (5400 rpm).

The five-axis operating unit and drilling head work independently, thanks to two separate Z-axis screws, for quick tool change for different applications.

The sensor for automatic tool measurement and calibration accurately measures the length of the tool, reduces machine setup time, which greatly facilitates the work of the operator.

The bed has the form of a frame structure with stiffening ribs and ceilings made of all-metal sheet, this provides a reliable base for further fastening of all units and assemblies to it. High precision of execution guarantees precise movement of the console and spindle, which subsequently affects the accuracy of processing.

The machine in the basic configuration has a conveyor for removing chips and small residues of workpieces.

Additional blowing of the processing zone ensures effective removal of chips from the cutting zone, which significantly affects the quality of processing and tool life.

Z-axis ball screws - movement is carried out using a TBI ball screw (Taiwan), which guarantees the complete absence of backlash, and subsequently high accuracy of movement.

The digital acceleration control together with the high rigidity of the structure allows high speed movements without vibrations.

The toothed rack and pinion with teeth ground from hardened steel provide high precision and smooth running due to minimal friction and no backlash. The pinion is integrated into a high precision planetary gearbox.

HIWIN (Taiwan) rolling guides and bottom brackets provide smooth running due to minimal friction, while maintaining a tight grip and precision accuracy.

Delta Electronics high power X/Y/Z 1/0.5/1kW servo motors and SESAME Motor Taiwan precision planetary gearboxes provide synchronous movement, high precision and dynamics.

Working table for 8 traverses with digital display and SCHMALZ vacuum blocks allows you to quickly position the part. Possibility of installing up to 8 vacuum blocks on each profile.

Quick change clamping device.

Choose accessories according to technological requirements.

The pendulum mode of operation divides the desktop into two zones - this allows you to set various processing programs in these zones and can significantly reduce the operating time (cycle) of the machine, the time when processing takes place in one of the zones, in another operator performs machine maintenance (workpiece change ).

The automatic lubrication system lubricates all necessary components and assemblies.

All equipment of the KDT plant uses electrical components from trusted manufacturers. They are interchangeable, thereby increasing the efficiency of service maintenance and quality control. These are mainly Delta Electronics, INVT (Innovation Value Teamwork), some configurations use special-purpose components from Schneider Electric, Siemens, Lenovo (industrial computer).

Vacuum system with a capacity of 244 m3/h securely fixes the workpiece.
