BASE AND WAGON

Base is built in a single cast iron Meehanite ® with oversized ribs able to withstand the most severe stresses. This is subjected to outdoor stabilization treatment for a minimum period of 6 months, allowing to eliminate the remaining internal tensions; The "slant" type geometry  (including 45°) has been designed to facilitate chips evacuation and the accessibility to the machine by the operator. Base and wagon 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 base are obtained the two upper flat guides for longitudinal movement of the wagon (Z axis) and the two lower ones for the tailstock.

GUIDES

The lathe guides are flat, cut directly from the machine base. Wagon, turret and tailstock movements takes place between the materials cast iron on steel with a thread of oil interposed to pressure. In this way Turcite or other antifriction material necessary for handling is not used, thus allowing a strong stability during processing and at the same time an increase in the life of the guides, drastically reducing the maintenance of the same.

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 transmission of the motion is carried out by a belt with a 2-speed mechanical gear box. A Fanuc α30i (30-37 kW) motor is mounted.

TOOLHOLDER TURRET

The turret has 10 stations (option to 12) on which tools can be mounted in radial and axial position; it is prepared for the  coolant exit 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. (tool to tool).

TAILSTOCK

It has a Meehanite ® cast iron structure. The body is positioned by attaching to the turret wagon, thus taking advantage of the handling of the Z axis. The tailstock has a diameter of 150mm, and the stroke of the boat is 150mm.

CHIP CONVEYOR

It’s positioned with the drain facing the tailstock, hinged type. Its maintenance and cleaning is extremely simple and fast, extracting it from the front of the machine. The dimensions of the conveyor have been sized for a long life while having to evacuate a large amount of steel chips or other material. The chip pick-up trolley is included also.

REFRIGERATION TOOL UNIT

It is complete with a very large collection tank capable of collecting up to 850L pump and pipes for the refrigeration of tools; supply is brought directly to the turret. Upon request the system can be 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.
