CW6636X5000 Big Hole Oil Pipe Lathe
Main feature:
1. Bed
The bed is a basic component of the machine, and its rigidity directly affects working performance and accuracy of the whole machine. The bed are made by the press of resin sand mould and the materials of high quality iron casting and this has excellent exterior and strength. The bed also has features of strong rigidity, anti-shock ability and anti-section deformity ability because of the construct of -typed ribs and the process of 450 side and rear chip removal. Width of guide-ways is 600 mm, this dimension is very bigger, and it has a better anti-subversive capacity when cutting large-sized swiveling work-pieces. The bed has V-typed and flat guide-ways for longitudinal traverse of the apron and tailstock.
2. Spindle box
The spindle box is a construction of whole box. The movement of main motor will be transmitted into the spindle box through V-belt. The change of moveable gear is adjusted by control handle, the range of spindle speed is 5 to 315 r/min. The transmits of main drive has two advanced roads, which is separated for high speed and low speed, so wide range of spindle variable-speed is realized economically and effectively. This driving system has characters of big torque output
3. Tailstock
The tailstock is consisted of up and lower bodies. The sleeve, spindle, manual and rapid traverse mechanism for sleeve, and adjusting spindle center line mechanism of the tailstock are wholly installed in the up body, the stopping mechanism is installed in the lower body. The tailstock can do longitudinal traverse along the guide-way of the bed, and it can support all kinds of work-pieces, and mechanical locking fastness will be realized, it is safer and more reliable.
4. Saddle and tool post
Main functions of this part by the frame of reference of the spindle finish various kind of feed. To prevent the feed of saddle from climbing longitudinally, a pair of guide-ways of the saddle has stuck with plastic guiding plates of high performance, the problem for cross and longitudinal combinational traverse has thoroughly been solved in the construction of longitudinal and cross branch, reliability of the machine is raised greatly. In additional, the up tool post can cut different taper within the effective travel.
5. Taper turning device
This device is installed at the end of the saddle, it can drive the saddle and tool post to turn taper ≤ 20° , length of the taper ≤ 300 mm, so it can turn pipe threads conveniently and reliably. Also this device with the length 800mm can be equipped with.
6. Feeding device (Out board support)
In order to clamp the pipe conveniently, the feeding device is installed in the saddle, and a handle is set on it. When moving the handle with hand, this pipe can go from chuck to rear chuck through the spindle hole automatically, easy for clamping the pipe, at mean time, the pipe which has been machined may be unloaded from the front or rear chuck, the device can be selected more according to the length of this pipe. This device has function as roller supporting, it can support long pipe.
