COMEV S.p.A. was established as soc. coop. COMM r.l.  by 13 workers coming from a factory, which was already a producer of parallel lathes.  In 1971 it became a Joint Stock Company and took the current name.  COMEV has always produced parallel lathes and up today 7500 machines have been manufactured.

In our installed base take place all stages necessary to get the end product and in particular the milling, hardening, grinding on CNC machining centres.

First matters produced on the spot, together with tested and reliable quality component industry, assure the high standard of our products.

Being the 90% output of all machine components on-site, COMEV can provide direct assistance and spare parts for machines produced in the 60es both in Italy and foreign countries.

Planning, development and manufacturing are due to our workers and technicians, whose work assures high quality and reliable products.

COMEV’s years long experience with producing and managing, together with the contribution of experts in high level software has allowed us to develop a powerful CNC equipped with a programming system, which has been adapted to the turner’s needs.

HEAD

G25 cast iron box, with a strong structure and ribs to remove vibrations, contains the spindle tree and the gearing change.

The gear system, equipped with three gears, permits the optimal exploitation of the available torque over a wide range, without loss of power.

The gear system can be set to work in fixed gear mode or continuous selection.

SPINDLE

The spindle, made of special steel NiCrMo, is cemented, tempered and precisely grinded.

The spindle is equipped with a ASA 11” attach system for the insertion of a bar of 160 mm. This insures interchange, stiffness, precision and security when mounting and dismounting the self-centering.

BASEMENT - BENCH

It is a unique, very strong cast iron fusion, it receives a relaxation treatment ,before it is machine worked, that eliminates internal tensions caused by the fusion itself.

The structure has a third guide. This solution guarantees an high stiffness of the X axis when working with large diameters.

Indeed, the loading, caused by the transverse cart, by the turret weight and by the effort of the working cycle, is centered on that guide offering in this way a great steadiness to the

transverse slide and precision to the worked piece.

It also permits to use the full length of the X axis without the need to use particular expedients to work the maximum diameter admitted for the bench.

CART GROUP

The cart is made of a G30 cast iron fusion, well dimensioned and robust, with sliding guides covered with antifriction material and scraped by hands.

The command screws both for the Z axis and the X axis, are with bearings recycle with preloaded snails with 0 gap, grinded with precision class ISO 5.

They are protected by graduated drums with divisions for easy reading.

The transverse slide guides, the bench prismatical ones and the command screws are all lubricated by a timed electropump and proper proportioner valves.
