Company of group of machine tool of plain of the Qin Dynasty is in exhibition of machine tool of the 10th China International (CIMT2007) showpiece heavyweight product, namely the VTM180 ／ with newest successful development mill of car of linkage of 5 5 axes is compound machining center. This machine tool is in large mill of car of vertical of 5 axes linkage is compound fill of machining center domain the country is blank, make the machine tool that domestic head stage can have exceeding big norms helix bevel gear is machined. This product is in former VTM180 mill of car of dragon door type is compound on the foundation of machining center, the mill of has own intellectual property car of 5 axes linkage that development goes is compound machining center. It is to be aimed at generate electricity, the demand that the motivation such as hydraulic turbine, turbine equips and develop development, apply to aerospace, shipbuilding, generate electricity, machinery of war industry, serious chance, engine, machine tool, spin, printing machine instrument, mould is made those who wait for an industry is medium the treatment of bevel gear of the component of appearance of large and intricate geometry, large helix and integral impeller. VTM180 ／ 5 have 7 axes 5 linkage function, through be being placed to outfit of workpiece, can finish already large the turning function that place establishing a car has, can fulfil the milling function that large pentahedral Long Menxi has again. Workpiece installs clip hind in but high accuracy, efficient finish mill, boring continuously, auger, the treatment of a variety of working procedure such as bore with a reamer, tap. This machines and tools has overall the construction is reasonable, the operation is simple, adjust convenient, precision is stable, function is reliable wait for a characteristic. In addition, on treatment helix bevel gear, the biggest diameter can be amounted to 2.
4 meters, diameter of the biggest circumgyrate can amount to turning 2.
8 meters, to the treatment of large helix bevel gear, precision can achieve 7 class above. This machine tool solved sheet effectively the production difficult problem of the helix bevel gear of small lot and big norms, the special software on the machine tool is wrapped, can use the helix bevel gear that establishs milling cutter and angle milling cutter commonly to machine high quality on machining center of 5 axes linkage. The helix bevel gear that uses this software to include treatment and the helix bevel gear that use international popularity to make type have parameter of identical tooth flank geometry, the equipment after assured prototype or be being maintained and original design have complete oneness. Because use general cutting tool, shortened greatly treatment preparation is periodic, reduced the devoted the first time cost of cutting tool, reduced sheet substantially the production cost of small lot and bevel gear of big diameter helix, shortened production cycle. Especially the helix bevel gear to big diameter, if use angle milling cutter, its machine the rolling cut of tradition of efficiency prep above to machine a method. The development that this software includes also broke through the bottleneck that bevel gear of helix of domestic big diameter makes at the same time, fill the blank of engineering capability of bevel gear of helix of two meters of above of domestic, those who be a lot of heavy equipment is homebred change levelled road. The product will be used at 1 above all.
Rig of 20 thousand meters of oil is made in. CNC Milling
