Victor Taichung - VMT-X200

BASE AND WAGON

The basement 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 geometry of the "slant" type (including 45°) has been designed to facilitate the evacuation of chips as well as the accessibility to the machine by the operator. The base and the 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. In the upper part of the base are obtained the roller guides for the longitudinal wagon movement (Z1 axis) on which the sled (X1 axis) is made. At the bottom is placed the static turret with independent movement (B axis).

GUIDES

Lathe guides are linear rollers guides of the best steel brands. An efficient automatic, timed forced lubrication system ensures constant lubrication on all contact surfaces. Guides dimensions are such as to make the specific pressure very low even under very heavy loads and stresses of work greatly increasing the speed of the rapid processing.

TILTING HEAD

It has a monolithic structure in Meehanite ® cast iron. The structure is "thermally symmetrical" to limit the effects of any temperature ranges that may be generated. The tilting head contains the 12000rpm DDS (Direct Drive Spindle) electrospindle. The head is positioned as a continuous B-axis with a resolution of 0.001° and includes a working angle from - 30° to + 210°. An effective oil refrigeration system that is pumped through the electrospindle allows us to keep the temperature controlled during the entire period of use even at full capacity. It has a Fanuc Bil 132S/15000 engine (15 - 18.5 - 22kw).

SPINDLE LINES

These lines have 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. Both spindle lines are driven by DDS (Direct Drive Spindle) motor, very powerful that allows to have an excellent precision for an optimal finish and at the same time a lot of power for a high removal. It has a Fanuc Bil 132S/15000 (15-18.5-22 kW) engine.

TOOL CHANGE

The automatic tool change system consists of a "chain" type magazine positioned on the right side of the column and a double-grip exchanger arm. The storage capacity is 40 seats. There are 48 and 60 tools options. The system is anchored to a monolithic Meehanite ® cast iron structure, which in turn is fixed to the machine base thus releasing the tool change from other machine movements. The tool magazine is completely covered by means of a pneumatic door that opens and closes allowing the arm to carry out the exchange thus avoiding the entry of chips and dirt. The exchanger arm is built according to concepts of remarkable strength and reliability over time. The selection of the tool type "Random" bidirectional, with search of the tool according to the shortest path allows a quick pre-selection during processing, then in time masked. The tool change is very fast: it takes only 2.0 sec. (Tool to Tool) to make it.

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 560L, 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 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.
