Product Overview
The 025A Full Automatic Saw Blade Grinding Machine grinds circular saw blades with outer diameters from 80 mm to 810 mm. It handles blades with inner diameters from 10 mm to 220 mm, thicknesses up to 8 mm, and circular pitches from 7 mm to 100 mm. The machine performs gear grinding, tooth surface grinding, and angle grinding with adjustable parameters. It is designed for use in sawmill production lines and blade reconditioning operations. The machine operates with a 50 litre/min cooling water pump and a 1.6 kW total power supply. It is part of a timber wood cutting machine system and supports blade sharpening and resharpening in high-volume environments.
Key Benefits
- Automates tooth and gear grinding on circular saw blades, reducing manual labor
- Supports blade sizes from 80 mm to 810 mm outer diameter and 10 mm to 220 mm inner diameter
- Adjustable grinding angles from -20° to 40° for oblique grinding and 6° to 45° for after angle gear grinding
- Grinding speed adjustable from 0.5 mm/s to 10 mm/s for consistent results across blade types
- Built-in cooling system with 50 litres/min pump and 85 kg tank capacity to prevent overheating
- Net weight of 980 kg provides stable operation during high-speed grinding at 2626 m/s
Application Scenarios
- A sawmill upgrading from manual blade sharpening to automated grinding for consistent tooth geometry
- A wood board plant reconditioning used saw blades to extend service life and reduce replacement cost
- A saw blade manufacturer adding a full automatic grinding step to a production line
- A workshop needing to process blades with varying circular pitches and tooth counts without retooling
Who It Is For
- Sawmills and wood processing plants
- Saw blade manufacturers and reconditioning shops
- Wood board and timber production lines
- Facilities that process circular saw blades with diverse sizes and pitch ranges
Problems It Solves
- Manual blade grinding leads to inconsistent tooth angles and uneven wear across blades
- Lack of automated cooling causes blade overheating and loss of hardness during sharpening
- Changing blade sizes requires frequent manual adjustments and tooling swaps
- Inconsistent gear grinding leads to poor cutting performance and increased blade vibration
Technical Features
- Hydraulic or mechanical feed system for gear grinding with adjustable mileage from 0 to 25 mm
- Adjustable oblique angle grinding from -20° to 40° and after angle gear grinding from 6° to 45°
- Tooth surface grinding range from -15° to +15° for precise edge alignment
- Addendum angle adjustment from -45° to +40° to match blade profile and cutting depth
- Integrated cooling water pump at 50 litres/min and 85 kg tank capacity for continuous operation
- Control panel with speed and angle settings, allowing real-time adjustment during grinding

Materials
- Circular saw blades with outer diameters 80 to 810 mm
- Blades with inner diameters 10 to 220 mm
- Blades with thickness up to 8 mm
- Blades with circular pitch from 7 mm to 100 mm
- Blades requiring gear grinding, tooth surface grinding, or oblique angle correction
Manufacturing And Process
Step 1
Load the saw blade onto the machine with the correct centering and alignment
Step 2
Set the grinding parameters: oblique angle, after angle, addendum, tooth surface, and gear grinding speed
Step 3
Start the cooling water pump and confirm flow before beginning grinding
Step 4
Engage the grinding wheel and begin the automated feed cycle for gear and tooth grinding
Step 5
Monitor the process for overheating or vibration; adjust speed or angle if needed
Step 6
Unload the finished blade and inspect for consistent tooth profile and edge sharpness
Quality Control
- Grinding angles verified against set parameters using calibrated angle gauges
- Cooling water flow checked before each run to prevent thermal damage
- Sample blades ground and inspected for tooth consistency and surface finish
- Machine calibration performed before shipment and after installation
- Operator training includes verification of angle and speed settings before production
Customization Options
- Voltage and phase configured for the destination market
- Grinding speed and angle settings adjustable to match specific blade types
- Machine can be integrated into a larger timber wood cutting machine line
- Optional tooling sets available for specific blade sizes and pitch ranges
Compared With The Alternatives
| Manual Saw Blade Grinding | Manual grinding requires skilled labor, has inconsistent results, and cannot maintain repeatable angles or speeds across batches |
|---|---|
| Semi-Automatic Grinding Machines | Semi-automatic models require more operator input and lack full automation of feed, cooling, and angle control |
| CRA-800 Bias Airway Buffs Forming Machine | The 025A is for saw blade grinding; the CRA-800 is for forming buffing wheels. Different processes, materials, and output types |
Use Guide
- Ensure the blade is properly centered before starting grinding to avoid uneven wear
- Check the cooling water level before each shift; refill if below 85 kg capacity
- Use the adjustable gear grinding speed to match blade material hardness—slower for hard steel, faster for softer alloys
- Verify the oblique angle and after angle settings before running a new blade type
- Keep the grinding wheel clean and free of debris to maintain cutting efficiency
