Design advantages

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

Vacuum table with working area 3100*2150*230 mm for 6 vacuum zones with electronic control. It is possible to work in pendulum mode and with small parts.

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 is equipped with a modern powerful electrospindle 13.2 kW from the Italian manufacturer HSD, "ES951 e-core". 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 16-station automatic tool changer will provide the machine with the necessary stock of used milling cutters and will 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.

Drilling group for 10 vertical spindles with a power of 1.7 kW, 6000 rpm and a bore diameter of 10 mm.

An effective chip removal system into 2 separate aspiration outlets - for the milling unit and the drilling group, improves the quality of processing and prevents damage to parts. The efficiency of aspiration is complemented by an intelligent airflow system installed directly on the spindle. The system allows you to direct the air flow in the direction opposite to the current processing and keep the cutting area clean, which improves the quality of the cut.

The sensor of automatic measurement and calibration of the tool makes an accurate measurement of the length of the tool, reduces the setup time of the machine, which greatly facilitates the work of the operator.

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

Gear rack and pinion KAI HE (Taiwan) with teeth ground from hardened steel provide high accuracy 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.

High power INVT 1.5KW servo motors and SESAME Motor Taiwan precision planetary gearboxes ensure synchronous movement, high precision and dynamics.

A dual-circuit lubrication system lubricates all necessary components and assemblies - automatic lubrication system along the X / Y axis, manual lubrication system along the Z axis.

Pneumatic lifting jacks provide precise positioning and ease the operator's work.

The workpiece pusher / workbench cleaning reduces maintenance time and prevents chips from getting under the workpiece, which significantly affects the quality of processing, facilitating the work of the operator. At the same time, it collides workpieces and cleans the table from chips.

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).

2 Becker vacuum pumps of 5.5 kW each with a capacity of 250 m3/h each ensure a secure fixation of the workpiece.

The automatic loading mechanism allows the machine to load panels independently and be used in automated lines when loading tables are connected.
