. Equipment Overview
The large straight knife grinder / CNC paper cutter grinding machine is designed for precision grinding of woodworking blades, panel knives, and paper cutting blades. CNC control and servo drive allow automatic roughing, finishing, and compensation for consistent sharpness, meeting high-precision blade requirements in furniture, panel, and woodworking industries.
2. Key Features
1. High-Precision Structure
The bed is made of double-layer high-quality steel, heat-treated and precision-machined for maximum rigidity. 35# linear guide rails with dust covers ensure stable, accurate CNC blade grinding.
2. Automated CNC Control & Servo Drive
Full servo CNC system with PLC programming allows automatic rough/fine grinding, multiple passes, compensation, and memory functions. Supports single or double-end grinding and automatic origin return, improving productivity for woodworking and panel blade grinding.
3. Precision Feed & Lifting
Grinding head feed combines manual and CNC automatic modes. Ball screw ensures feed 0.005-0.10 mm. Lifting motor 1.05 kW enables fast, precise adjustment for consistent blade surface quality.
4. High-Performance Grinding Head
Dedicated grinding head motor provides smooth operation, large grinding capacity, long life, and high precision, suitable for paper cutters, straight knives, and panel blades. Left-right travel via VFD-driven rack & pinion with worm gear ensures quiet and stable operation.
5. Cooling & Lubrication
Independent water circulation cooling system maintains blade temperature. Centralized automatic lubrication enhances CNC blade grinder stability and convenience.
6. Precision & Durability
Spindle face error ≤0.02 mm, axial backlash ≤0.02 mm, radial runout ≤0.02 mm, blade straightness <0.03 mm, surface roughness RA <1.6 um, meeting woodworking, panel, and paper industry standards.
7. Safety & User-Friendly Operation
Independent electrical cabinet with touch screen + buttons, lighting, and safety guards, suitable for long-term continuous operation.
