CNC Heavy-Duty Roll Milling Machine XK8450H, XK8460H

• Aiming at the problem of high-speed steel roll processing.
• The XK8450 CNC roll milling machine is a new type of CNC roll groove processing machine tool developed after fully researching .
• And analyzing the advantages and disadvantages of similar products at home and abroad based on the company’s XK9350 series.

Product Introduction of CNC heavy-duty roll milling machine XK8450H, XK8460H：

• A milling machine heavy duty is suitable for processing rebar rolls with a diameter of less than 650mm and a length of less than 2500mm.
• It can automatically process various specifications of crescent grooves .
• And contour rib grooves for φ6~φ50 rebar rolls (fully compliant with GB1499-2018 standards).
• The milling machine can automatically cut crescent grooves with different rotation directions and any helix angle according to customer requirements.
• It can divide into equal (or unequal) divisions or spaces in the circumferential direction of the roll.
• It can automatically engrave product specifications, Grade, trademark and other marks.
• Any groove shape, text can also process non-standard rolls., and markings according to user requirements.
• Achieve the purpose of high degree of automation, outstanding functions, and multi-purpose cnc machines.

Structural description：

• This series of machine tools all adopt an integral 4-rail bed structure.
• And the reference guide rails adopt integral super-audio quenching, which ensures the high rigidity, high precision and stability of the entire machine.
• And adopts a fully protective structure.
• The lateral moving guide rail of the flying cutter milling head component is supported by high-precision heavy-duty linear cylindrical rolling guide rails.
• In order to ensure the high precision and high rigidity requirements of feed motion during the flying knife machining.
• The workpiece spindle transmission adopts a gap-free connection method to ensure transmission accuracy and control backlash.
• Subsequently, the centralized control operator configures the rotary flying milling head.
• The machine tool realizes function conversion automatically.
• There is no manual mechanical conversion.
• As long as the operator completes the selection on the cnc machines system，The selection is of simple processing modes.

Throwing Knife Instructions：

• Particularly, the flying knife shaft transmission chain completely uses gears.
• These gears are 6-level precision ground ones.
• It ensures the tool trajectory fulfills the requirements totally.
• And especially eliminates hidden flaws such as groove mismatch and broken tools caused by the poor precision and rigidity of the transmission chain.
• Particularly, it shows its excellent performance in the processing of small-sized tungsten carbide roller rings.
• The flying knife spindle uses a large-diameter H40 spindle end, which can meet the requirements for processing 60mm contour ribs.
• The longitudinal and transverse linear motion axes of the machine tool are driven by high-precision ball screws to avoid the inaccuracy of gear and rack transmission.
• Under the automatic control of the CNC system, automatic movement and precise positioning from one hole pattern to the next can be achieved.
