4.Product Introduction:
The machine tool produced by our company, whose bearing capacity is 18t. belongs to general one of muti-function series, with the feature of high accuracy, high reliability, high rigidity, precision manufacturing as well as beautiful appearance, the machine tool can be
used for rough or finish machining of metal or non-metal as well as turning of end faces, excircles and inner holes of workpieces, moreover, it can also achieve turning operations as short taper, metric, BPS and module threads with the motor-driven upper tool rest individually. The machine tool has been the first choice
equipment for paper making machinery, glue roller manufacturing, maintenance, railway, mould large valves and metallurgy roller etc. of machining and manufacturing industries.
5.Features:
Headstock
The spindle, with its 240mm front diameter, has the feature of high rigidity and high accuracy.
The spindle bearings in the spindle box of the machine all adopt Japanese KOYO-P5 or the domestic famous brand products with D grade. The three-supporting structure has endowed the spindle with the characteristics of high rigidity, high strength, high accuracy as well as high stability. Besides adopting hydraulic braking system to compensate for the abrasion, the spindle is fairly effective with the integration of hydraulic system and lubrication function. Heat-scattering measures are added in the spindle box who also adopts bath lubrication. Bearings of spindle have been pre-tensioned and all gears in the box have undergone quenching-grinding process to ensure high rotating accuracy and low noise. Rotating speed: 3-136 rpm, 12 steps; motor power: 30 KW, 4p motor.
Machine bed:
Due to the mixing arrangement of V-flat guideways, the machine bed is endowed with an excellent technology. With 1100mm in width, 710mm in height, and box shape canting pull plate structure of high rigidity, the bed has a great feature of stability and bearing capacity. Moreover, the entire bed is in a casting structure and reasonable stiffened plate arrangement internally. The guideways adopt the middle frequency quenching-grinding process which makes them have a very good hardness. Technological measures will be taken, such as sticking crawl-preventing guideway plate on the surface of slide guideways to make the dynamic features such as rigidity of feed system and friction damping coefficient be in their best status, thus avoiding occurrence of low speed crawl.
Chuck
The standard configuration of machine tool of the series is manual-operated chucks with diameters of 1250,1400,1600,1800 mm. Chucks are made of casting steel materials with static balance technology.
Feed box & Slide box
For this part, we will totally adopt CT series which are fairly mature and reliable products of our company. The boxes are driven by electromagnetic clutches of simple structure and high reliability, which makes it very convenient for maintenance. Meanwhile, the cross handle switches also provide us a compatible operation.
Tool rest of the saddle
For each series, it is endowed with the function of automatic feed. With the structure of double layer compound rest whose diameter is over 1400mm, it can easily realized the longitudinal and cross feed. The four-working-position rest can rapidly change tools and clamps them accordingly.
Tailstock
The tailstock adopts a structure with high bearing capacity, and the handles equipped on the side are very easy for operation. There are also active centers inside. Besides the feature of high rigidity and rotating accuracy, the tailstock is equipped with rotating and fixing conversion devices. The motor-driven tailstock, whose sleeve diameter is 240mm and stroke is 250mm, also has the backward preventing security mechanism and sleeve force-measuring mechanism.
Hydraulic system
The system can be effectively and rapidly performed with hydraulic braking. For lubrication, it is the same system used in machine head. Main hydraulic elements are all produced by Taiwan ChaoTian of good quality and high working reliability.
Cooling and chip disposing system
The standard configuration of the machine will adopts chip pan for chip disposal. The cooling box will be separated from the main set to avoid the machine accuracy being affected by heat caused by cutting. The system will adopt home-made cooling pump, and the cooling box will be installed in trench.
