XK8450FD CNC heavy-duty roll milling machine

Aiming at the problems of high-speed steel roll processing, XK8450 CNC roll milling machine is a new type of CNC roll groove processing machine developed and developed on the basis of the company's XK9350 series after fully researching and analyzing the advantages and disadvantages of similar products at home and abroad. The machine tool 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 equal height rib grooves for φ6 ~ φ50 rebar (full compliance with GB1499-2018). The machine tool automatically cuts crescent grooves with different rotation directions and any spiral elevation angles according to customer requirements. It can arbitrarily divide (or unequal) divisions or spaces in the circumferential direction of the roll; it can automatically engrave product specifications at any position on the roll. Marks such as grades, trademarks, etc. It can also process arbitrary grooves, characters and marks on non-standard rolls according to user requirements. To achieve the purpose of high degree of automation, outstanding functions, multi-purpose.

This series of machine tools all adopt the overall 4-rail bed structure, and the reference rail adopts the overall super-audio frequency quenching, which highlights the high rigidity, high precision and stability of the whole machine. And adopted a full protection structure.

Flying cutter milling head component lateral movement guide rail is supported by high-precision heavy-duty linear cylindrical rolling guide rail. To ensure the high precision and high rigidity of the feed motion during the flying knife machining.

Workpiece spindle drive adopts a gapless connection method to ensure the maximum transmission accuracy and control the backlash.

The parallel configuration of rotary fly milling head and swing engraving and milling head, centralized control The operator only needs to complete the selection of simple machining mode on the CNC system, and the machine tool automatically realizes the function conversion without manual mechanical conversion.

Flying cutter shaft drive chains all use 6-level precision grinding gears to ensure that the tool path fully implements the CNC system program instructions. It eliminates hidden defects such as groove misalignment and knife breakage caused by poor precision and rigidity of the drive chain. Especially in the processing of small-sized tungsten carbide roller rings, its superior performance is more prominent.

Flying cutter spindle adopts large diameter H40 spindle end, which can meet the requirement of processing 60mm equal height rib.

The longitudinal and horizontal linear motion axes of the machine tool are driven by high-precision ball screws to avoid the inaccurate gear and rack drive. Under the automatic control of the CNC system, it can realize automatic movement and precise positioning from one hole pattern to the next.
