Product description
Parameters
1. Introduction of Machine Tool
XK500H Rebar Roll Crescent Groove CNC Machining Combined Machine Tool is a special processing machine tool for processing rebar roll "Crescent Groove" The bed, saddle, milling head, headstock, tailstock and other transmission components are all manufactured or selected according to the precision required by the CNC machine tool. The control system uses the Siemens CNC system, which is more stable in control and improves the performance of the machine tool. The efficiency of cutting large-scale thread roll "crescent groove" is significantly improved, and the performance of cutting tungsten carbide roll ring is also enhanced.
The special machine tool is suitable for processing rolls with a diameter less than 500mm and a length less than 2500mm. The processable thread "crescent groove" specification is 5 ~ 50mm. It can automatically cut "Crescent groove" of different specifications and different rotation directions. Equal (or unequal) divisions or spaces; can automatically engrave product specifications, grades, trademarks and other marks on any position of the roll. It can also process arbitrary grooves, characters and marks on non-standard rolls according to user requirements. To achieve the purpose of outstanding functions, multi-purpose machine.

2. The machine tool is a fully automatic processing machine tool with four servo motors and four servo drives (patent number ZL201720076022.5). It is equivalent to the current five servo-controlled machine tools, which improves the machining accuracy and production efficiency of the machine tool, which can greatly reduce the labor intensity of workers and allow users to enjoy the performance brought by fully automatic machine tools.
3. The machine tool is designed according to the heavy-duty roll machine. The bed adopts three parallel guide rails, and the guide rail surface is super-audio frequency quenched, with good accuracy retention and good shock resistance.
4. The machine tool adopts high-rigidity ball screw nut auxiliary drive in both vertical and horizontal directions, which can realize one-time roll tool setting and continuous processing of porous automatic positioning.
5. Adopt high-performance numerical control system, which can realize automatic programming, and automatically realize the processing and engraving marking of any spiral rising angle with different hole types and different rotation directions. It can automatically make any equal division, any job change, and automatically engrave the factory standard, specification code and other signs.
6. The machine tool overcomes the shortcomings of the similar products of the headstock worm gear and the main shaft intermittently, which affects the processing quality. The taper surface contact is adopted to ensure that the processing is always without intermittent state, and the service life of the product is improved.
7. The main shaft bearing of the headstock adopts oil pool lubrication, which is the first of its kind. It ensures the lubrication of the bearing and reduces the problem of unstable main shaft transmission caused by the thermal deformation of the bearing. Machine tool stability.
8. The tailstock of the machine tool adopts the retreat device used by the heavy-duty machine tool to ensure that the tailstock will not have any displacement during the cutting process of the machine tool. It also guarantees the normal use of the machine tool.
9. Main precision items of machine tool:
Spindle axial movement ≤ 0.01mm
The radial runout of the spindle taper hole near the spindle end
300mm place ≤ 0.02mm
The parallelism of the slide plate movement to the axis of the main shaft
In the vertical plane 0.02 / 300 (only upward deviation)
0.015 / 200 in the horizontal plane (only forward deviation)
Parallelism of sliding plate movement to tailstock sleeve axis
0.015 / 300 in the vertical plane (only upward deviation)
0.015 / 200 in the horizontal plane (only forward deviation)
The equal height of the spindle and tailstock center 0.02 ～ 0.06
Cross-rib milling precision
Transverse rib depth 0.01mm
Lettering depth 0.01mm
Transverse rib surface roughness Ra3.2
Min. Unit of vertical and horizontal movement 0.001mm
