Product details

The QD528 is a 5-axis 5-link CNC tool grinder which is independently R&D by Qiandao company. It is an excellent tool grinding center suitable for the production or grinding of milling tools, drilling tools, forming tools, etc.

The machine features a user-friendly Human-Machine Interface, high-rigidity cast iron construction with secondary aging treatment, ensuring superior stability.

The machine adopts direct drive frequency grinding spindle with high rigidity and precision. The spindle is 15KW big power. and the grinding wheel flange can be equipped with 2 to 4 grinding wheels at the same time, which can satisfy the grinding process of the front, back and end faces of the tool in one clamping need.

The workpiece spindle adopts dd direct drive. It is equipped with W25/W20 precision clamping system matching with Schauberlin precision collets, the workpiece is pneumatically clamped.

The machine tool is equipped with a NUM Flexium+ 5-axis linkage control system and NUM servo drives, incorporating Renishaw high-precision measuring probes, THK precision linear roller guides, a Z-axis C3-grade ball screw with FAGOR grating scale, and HIWIN linear motors with FAGOR scales on the X/Y axes. To further ensure dimensional accuracy of machining tools, the rotary axes adopt dual direct-drive (DD) motors with full closed-loop control, guaranteeing the machine’s superior performance and exceptional working precision.

The machine adopts totally enclosed frame(front sliding doors, left, right and back maintenance doors), hand-hold electronic hand wheel, special start and stop button, foot switch, automatic spindle cooling and workpiece coolant control device, automatic lubrication and mist absorbing devices, alarm buzzer, electrical box cooling air conditioner. Operation and maintenance are simple and convenient.
