Gear bench metal lathe Fervi 0716

The Fervi 0716 gear bench metal lathe is the ideal device for machining metal materials by removing cold shavings. It is a tool particularly suitable for processing such as turning cylindrical or conical pieces, profiling, threading, faceting, drilling and boring and cutting or parting. This type of lathe is designed for intermittent use during daily activities and not for intensive use as can occur in industrial or production departments. To perform the movements, the operator's command is required, which is why the machine is fully manual.

The Fervi lathe is equipped with a spindle head made entirely of cast iron, inside which two protrusions have been obtained which increase its rigidity. In this way it will be possible to reduce vibrations during processing. Equipped with 3-jaw self-centering chuck. This type of spindle allows the locking and centering of circular or polygonal pieces that have a number of sides divisible by 3. For the opening and closing of the jaws it is necessary to use the special key supplied.

The spindle rotation speed is managed by an electronics that controls DC motors with brushes. Through a two-position lever it is possible to modify the gear transmission ratio and choose between two rotation speed ranges: L: 100 ÷ 1100 rpm and H: 200 ÷ 2500 rpm. In the control panel there is a potentiometer: this allows to start the parallel lathe and to select the rotation speed within the selected range through the two-position lever. The potentiometer varies the voltage on the motor by reducing the speed and is flanked by a display that shows the number of revolutions.

The tool holder trolley slides along the guides of the pallet, which is used to fix the tools and to transmit them the movements of positioning and advancement. the parts that make up the trolley are made of cast iron with hardened and ground guides. To move the trolley the special handwheels must be used. The change of the feed speed of the gear bench metal lathe is with replaceable gears in plastic. The gears guarantee a high availability of feeds and threads. The selection of the steps takes place through the insertion of the related gears. The gearbox is located at the left end of the machine.

The tailstock is made of cast iron and has the task of ensuring rigidity and stability in all conditions of use. Its structure is equipped with a locking system on the lathe guides, with nut. To handle it it will be necessary to use the special crank.

This model of gear bench metal lathe is equipped with a motor with power 230 V 50 Hz 0.5 kW, which can therefore also be used with a normal electrical socket. the electrical and control panel, on the other hand, is positioned to the rear of the machine, between the spindle and the gearbox of the speed change.
