GENYMAB, THE MIXED de fraisage 15/29 kw (6000 tr/mn) TECHNONOGY : MACHINING CENTER HIGH GENYMAB 400 & 900 - Broche the union between a CNC Lathe and a milling center with an automatic tool changer The GENYMAB range belongs to a new GENYMAB 400 & 900 - Broche de reprise G900 8“ - generation of multi-functional machines offering performances of both CNC lathe and 5-axis machining center. Compared with traditional machining means, this range of machines offers very high productivity and super accuracy. Production cycles and work-in-progress are extremely reduced, so the production cost is...

SOMAB invented first turning & milling machine in the world Twenty years ago, there is no combined turning and milling operation on one machine. In 1986 SOMAB invented & developed a really multi-functional machine which was called POLYMAB European patented N° 0368977 and United States patented N° 5,052,089 (the first version of our Genymab ). It was first presented on the 1988’s biennial Machine-Tools exhibition in Paris. After experiencing continuous improvement, our Genymab machines have been greatly enhanced in accuracy, productivity, programming and additional features. Benefiting from...

Many machining operations available GENYMAB multi-functions machining center (or turning & milling machining center) brings solutions to all fields of activity : see examples of parts on this page. GENYMAB can realize special operations such as turning-planning, grooving, slotting, gear shaping, etc. Roughness of machined surfaces can even be lower than Ra 0.2. Accuracy for turning can reach 0.005 mm. GENYMAB can machine very hard materials such as nickel, chromium. The head can tilt and move in the whole working area so that the tool can be set to all possible orientations on the main...

STRUCTURE Excellent geometrical stability and great vibration damping One-piece Granitan bed base strong thermal stability As for the major part of its range, GRANITAN 100 (composite granite) has been selected by Somab as bed material which brings excellent geometrical stability and great vibration damping to the machine. Thermal conductivity coefficient of GRANITAN is about 50 times lower than cast iron. It provides a very high geometrical stability to the machine. As below diagram shows, its vibration damping is very important to improve machining properties, surface quality and tool life...

Compact and Strong COLUMN AND SADDLES The column, the vertical saddle and the ram on which the head is fitted, are all made of stabilized and heavily ribbed cast iron to assure machining quality for hardened material HRC 65. In order to provide excellent guiding and positioning with high rigidity we use pre-loaded guide-ways and ballscrews.

A powerful & high accuracy MAIN SPINDLE Spindle driven by separated motor through belt Two spindle nozes, 8 inches and 11 inches with different bore diameters are proposed. Assembled with super precision bearings, the spindle is driven by a separated motor with a high quality Polyflex type belt. A gear box is available in option for high torque needs. The spindle, the clamping cylinder, the chuck and the link tube are perfectly fitted and balanced in dynamics, thus ensuring perfect and efficient machining surface. In any case this spindle can be locked or driven at low speed as a C axis for...

SUB-SPINDLE Driven by a built-in synchronous motor with the above-mentioned advantages, a sub-spindle 6 inches or 8 inches is available. A part can be hold simultaneously by both synchronized spindles for different machining applications. Servo control of the push power of the sub-spindle carriage is available. It is very useful to hold a part automatically on the second spindle or to use the sub-spindle as a tailstock.

A multi-functional TOOL-HOLDER HEAD The head is fitted with a fixed attachment for turning tools and with a live spindle for milling tools. The same tapper shank (ISO, HSK, CAPTO...) can be fitted in either the fixed attachment or the live spindle. 12 12 Compact in structure and rigid in design, the head is firmly attached to the rotating B axis. It can be used in continuous up to 325°, from 0 to 30 rpm via a no-clearance transmission and measured by a ring encoder (increment : 0.0001°). It may be used in any fixed position or used as a rotary axis in order to realize complex machinings,...

Fixed attachment for turning A very robust fixed attachment catches the turning tool. The 45° position of the head optimizes the position of the short tool while external turning or facing. This very robust fixed attachment can receive ISO, BT, CAPTO or HSK tool attachements. There is an external coolant system and a through the center of tool coolant system. These coolant circuits can be used separately or simultaneously in any position of the head. Internal air-blasting is used to clean the taper while changing the tool. Live spindle for milling It can also receive ISO, BT, CAPTO or HSK...

FRONT TURRET SUITABLE for Quantity Production When machining large series of parts, the front turret is designed to realize all turning operations on the main spindle and also on the second spindle. Simultaneous machining, using the tool-holder head and the front turret in the same time, is also possible. TOOL CHANGER MAGAZINE with a great capacity The magazine of tools is fitted with a built-in digital tool changer. It has a capacity of 28 or 50, or120 tools on request. Maximum tool length in the magazine is 300 mm. An additional magazine for boring bars up to 500 mm is available on...
