Victor Taichung - V760

BASE, UPRIGHT AND CROSSBAR

The base, the upright and the crossbar are built in a single cast Meehanite ® cast iron with oversized ribs able to withstand the most severe stresses. These are subjected to outdoor stabilization treatment for a minimum period of 6 months allowing to eliminate the remaining internal tensions; the geometry of the base has been designed to facilitate chips evacuation and the accessibility to the machine by the operator. Base, upright and crossbar are designed according to the application of the analysis and design system (FEA). Using this system the computer determines the thickness and dislocation of the internal ribs. On the very stable base is fixed the upright on which are obtained the two flat guides for the movement of the Z axis. On the upright in turn is fixed the crossbar that supports the very rigid turret body on which are made the two flat guides for the movement of the axis X.

GUIDES

The lathe guides are flat. Z and X axes are moved by means of Turcite.The width of the guides of both axes are oversized thus allowing them to withstand even the most demanding machining operations.

SPINDLE LINE

It has a monolithic structure in Meehanite ® cast iron, fastened to the base on the base. The structure itself is "thermally symmetrical" to limit the effects of any temperature ranges that might be generated. An efficient cooling system with external cooling unit keeps the temperature constant. The motion transmission is by belt with ZF two-speed mechanical gear box. A Fanuc αP40i(18.5-22kw) motor is fitted as standard. A more powerful Fanuc α30i(30-37kw) motor can be fitted.

TOOL HOLDER TURRET

The hydraulic turret has 12 stations on which tools can be mounted in both radial and axial position; it is predisposed for the exit of the coolant both outside and inside the tool holders. The positioning and bidirectional rotation of the platter is guaranteed by an extremely fast and reliable Fanuc motor with an indexing time of only 1 sec.

CHIP CONVEYOR

It is positioned with the rear exhaust to the machine allowing a considerable reduction of the machine footprint. Its maintenance and cleaning is extremely simple and fast. Carpet dimensions have been dimensioned for a long life while having to evacuate a large amount of steel chips or other material. Also included is the chip pick-up trolley.

REFRIGERATION TOOL UNIT

It is complete with a very large collection tank capable of collecting up to 300L pump and pipes for the refrigeration of tools; the supply is brought directly to the turret tool. Upon request the system is equipped with additional high pressure pumps and systems for waste oil recovery in the tank to prevent the pollution of emulsions.

ELECTRONIC EQUIPMENT

The system is integrated with the machine CNC and is complete with a watertight cabinet. All controls as well as the steering unit are located at the front, while the control cabinet is located at the rear of the machine. An effective air conditioning system ensures that the operating temperature inside the electrical enclosure is controlled and constant to prevent that electronic components used from being damaged, especially in warmer seasons.

AUTOMATIC LUBRIFICATION SYSTEM

It includes the lubrication units, equipped with a timer and a series of dosing units for the automatic lubrication of: sliding guides - ball screws - bearings. An audible warning device warns us if the level has reached the minimum allowed while continuing to lubricate. To ensure that the system is fully functional there are pressure switches that measure circuit pressure that releases the liquid only when set pressure has been reached; if this does not happen due to leakage an alarm arises. The basement structure has been realized for the recovery of most of the waste oil in a special tray placed in the back of the machine.
