SMU series five axis universal milling machine
SMU series milling machine is a product that has been optimized for many times, This series are rich in configuration which users can choose according to actual needs. There are two forms of workbench, namely the rigid workbench and the rotary workbench. The machine is used as the three axis vertical machining center when the customer selects a rigid workbench, and a fourth axis is available to realize four axis linkage; If equipped with rotary workbench, then the machine changes into a cradle type five axis five linkage machining center, At the same time ,there are options of 40/60 tool library. The machine can be widely used in the fields of automobile, mold, aviation and spaceflight to achieve the Machining of complex surface parts.
SMU series five axis universal milling machine is a compact vertical five axis machining center, the salient feature of the milling machine is its innovative structure, the whole lathe bed casting of the machine is designed by the method of computer optimization to form a compact structure. The layout of the structure is reasonable in which all the main parts are distributed with a plurality of ribs and stiffeners, and adopts structure of Symmetrical temperature and symmetrical mechanical. Also, it has the advantages of good rigidity, high torsion strength, good thermal stability and high precision. All axes are driven by digital technology, forming a closed loop control, and the fast move speed of linear axis is 30m/min, At the same time, there are different spindle power torque to choose, and the maximum speed goes up to 18000rpm, showing an excellent dynamic performance.
①The spindle unit
The electric spindle unit adopts a compact, high rigidity electric spindle, which ensures the accuracy of the main shaft and the maintenance of the long-term precision by the long acting grease lubrication. The spindle with high reliability uses an electronic spindle positioning device, which ensures that the main shaft is stopped at a fixed position, and the cutter is clamped through a disc spring, a hydraulic clamping device and an oil cylinder.
The machine tool is equipped with an internal motor encoder (direct linear measurement system) for standard.and X, Y, Z axis straight line measurement uses direct absolute grating system for option. The measurement system is equipped with an aluminum sealed box, the compressed air is blown, so that the grating scanning box and its guide rail are free from the influence of chip, dust and cutting fluid.B, C axis NC turntable uses a direct absolute circular grating measurement system.
B, C axis of Rotary workbench is servo driven with double gear backlash mechanism, At the same time, the bearing with high bearing capacity has the advantages of high bearing capacity, accurate positioning and convenient maintenance.
④Tool exchange and tool library
Cutter changing is arranged by the automatic tool changing mechanism between the main shaft and the cutter library, and the capacity of the chain tool library is 40.
The machine can allow a pressure of 45Bar to achieve a large number of coolant wet processing, A large, fully sealed coolant tank with a high efficiency cooling pump and a short coolant pipe and a plurality of nozzles can provide sufficient cooling fluid. Customer can select the 45Bar high pressure center cooling water supply In order to ensure that the chip can be effectively removed in some special processing.
⑥Machine shield / machining area
Machine tool adopts compact semi enclosed protective cover with sliding door.
Optional: side door.
Processing area is accessible to workers easy to clean and easy to maintain the machine tool parts is its outstanding features.
⑦Compact structure, strong applicability
Compact structure with strong applicability is suitable for the requirements of the vertical five axis machine tool with compact space dimensions.
