Torgim TL 350/400 lathe is a machine for high cutting depth, it’s a perfect one to work forged pieces and very hard materials.
Headstock: The head, melted in special stabilized Meehanite cast-iron, is steadily fixed on the bed and it is free from vibrations. All gears are made of Cr.Ni.Mo. steel, hardened and ground. The spindle, provided with hole Ø 133 mm, is mounted on precision TIMKEN ball bearings. The machine has two mechanical gears with manual or automatic speed gear range by means of an hydraulic piston and relative unit. The spindle motor power is 18,5 kW. The project was checked with FEM method to verify very high cutting forces.
Carriage: The carriage slides on the bed guided in the front part by a prismatic guide and in the back part by a flat guide. With a solid structure it is able to stand to a strong cutting moment assuring a constant precision at the same time. The transversal slide has a support section very wide that gives it sturdiness. The ways of the cross slide are ground and adjusted by means of conic gibs: the ways between the movable parts are covered by TURCITE to allow motion regularity also at lowest feeds and are manually scrape-finished so to guarantee an accurate assembly. The movements are driven by high precision recirculating ball screws.
Bed: The bed, melted in special Meehanite cast-iron and covered on all the length, is carried out with a sturdy structure, to assure the highest stiffness, in the worst duty conditions too. The natural gap under the head increases the machining potentialities allowing to work very large flanges usually workable on lathes much more bulky.
Extra accessories: continuous “C ” axis, automatic turret 4/8 positions, VDI 40 driven tools, toolholder with internal cooling, tailstock with automatic sliding sleeve, automatic hydraulic or pneumatic self-centering chuck, swarf conveyor, unloading pieces unit.
