Product Overview
The QD580 by MINNUO is a 5-axis CNC tool grinding machine designed for manufacturing and regrinding of complex cutting tools. It combines a rigid mechanical frame, high-speed grinding spindles and an integrated CNC control with a tool database to perform simultaneous multi-axis shaping and profiling for carbide and HSS tools used in aerospace, automotive, mold and precision machining production lines.

Key Features

• 5-axis simultaneous CNC control for accurate geometry grinding.
• Supports manufacturing and resharpening of carbide and HSS cutting tools.
• Rigid machine base to minimize vibration and ensure dimensional stability.
• Integrated CNC with tool database and parametric programming for repeatable setups.
• Suitable for step tools, ball nose end mills, profile cutters and drills.
• Compatible with automation and robotic loading systems.

Recommended Configurations

• Spindle System: High-precision grinding spindles (belt-driven, electric or hydrostatic), spindle cooling (oil or air) and optional automatic spindle balancing.
• Workpiece Clamping System: Precision chucks and fixtures, universal V-block clamps, custom tool-holding fixtures and rotary workpiece systems.
• Grinding Wheel System: Automatic dressing (diamond dresser or single-point dresser) and dynamic balancing for grinding wheels.
• Feed and Motion System: CNC-controlled feed with adjustable speeds to match grinding operations.
• Cooling and Filtration System: Coolant circulation with adjustable nozzle injection and high-efficiency filtration (paper belt or magnetic separator).
• Control and Automation System: CNC or PLC control with HMI touch screen, optional in-machine probe for tool measurement and automated loading/unloading.
• Accessories and Optional Devices: Dressing tool holders, workpiece supports, integrated lighting and air-blow cleaning, chip removal and dust extraction systems.

Application Case

• Client: Cutting tool manufacturer — East China.
• Workpiece: Ø20 mm solid carbide end mills with stepped flutes.
• Setup: QD580 with 5-axis controller, in-machine measuring probe and mist collector.
• Results: Profile accuracy ≤ 0.006 mm; cycle time reduced by 22% versus previous 4-axis solution; resharpened tools recovered up to 90% of new-tool life.
• Client Feedback: “With the QD580, we achieved faster turnaround and tighter tolerance control; it is central to our regrinding line for HSS and carbide tools.”
