Milling cutter sharpeners are specialized tools or machines designed to sharpen milling cutters, which are used in milling machines to remove material from a workpiece. These sharpeners help restore the cutting edges of milling cutters to their optimal sharpness, ensuring efficient and accurate machining operations.
There are different types of milling cutter sharpeners available, ranging from manual hand-held devices to automated machines. Here are a few common types:
1.Manual Sharpeners: These are simple tools designed for occasional or light use. They typically consist of a handle or frame with a sharpening stone or grinding wheel. The milling cutter is manually moved against the rotating stone or wheel to sharpen its cutting edges.
2.Bench-Top Sharpeners: These sharpeners are more advanced than manual tools and are suitable for regular use. They are larger, bench-mounted machines equipped with grinding wheels, adjustable guides, and mechanisms to control the sharpening process. They provide more precise and consistent results compared to manual sharpeners.
3.CNC Sharpeners: Computer Numerical Control (CNC) sharpeners are highly automated machines used for sharpening milling cutters with precision. They utilize computer-controlled movements and advanced grinding mechanisms to achieve accurate and repeatable results. CNC sharpeners are commonly found in industrial settings where high-volume milling operations are performed.
Using a milling cutter sharpener involves several steps to ensure proper sharpening of the cutter blades. Here's a general guide on how to use a milling cutter sharpener:
1.Safety Precautions:
Wear safety goggles and gloves to protect your eyes and hands.
Ensure the sharpener is securely mounted on a stable surface or workbench.
2.Prepare the Milling Cutter:
Remove the milling cutter from the milling machine or holder.
Inspect the cutter for any damage or excessive wear. Replace any damaged or worn-out blades.
3.Adjust the Sharpener:
Refer to the manufacturer's instructions for your specific sharpener model.
Adjust the settings and angles according to the cutter specifications. This may involve adjusting the grinding wheel position, angle, and depth of cut.
4.Mount the Cutter:
Depending on the sharpener design, you may need to secure the milling cutter in a holder or jig provided with the sharpener.
Make sure the cutter is firmly held in place to prevent movement during sharpening.
5.Sharpening Process:
Turn on the sharpener and allow the grinding wheel to reach the operating speed.
Gently lower the cutter onto the grinding wheel, following the manufacturer's recommended technique.
Move the cutter across the wheel, applying even pressure to ensure consistent sharpening.
Use smooth and controlled movements to avoid overheating and damaging the cutter.
Take breaks during the process to prevent overheating of the cutter or sharpener.
6.Inspection and Adjustment:
After sharpening, remove the cutter from the sharpener.
Inspect the cutting edges for sharpness and consistency.
If necessary, make adjustments to the sharpener settings and repeat the sharpening process until the desired sharpness is achieved.
7.Clean Up:
Turn off the sharpener and unplug it from the power source.
Clean the milling cutter to remove any metal shavings or debris generated during sharpening.
Dispose of the collected metal shavings in a suitable manner.
It's important to note that the specific steps may vary depending on the type and model of the milling cutter sharpener you're using. Always refer to the manufacturer's instructions and safety guidelines for your particular sharpener to ensure proper usage and best results.
