Specification

NOTE:

1. During using, appropriately reduce the cutting speed and feed rate, which can prolong the service life of the milling cutter.

2. When working, it is necessary to add cutting fluid to protect the knife edge, so that the cutting is smoother.

3. When the oxide film or other hardened layer remains on the surface of the workpiece, it can be removed by reverse milling.

Aluminum machining requires specialized tool geometry to ensure smooth cutting and effective chip evacuation.

Our aluminum roughing end mills feature:

• Optimized flute design for aluminum alloys

• Large chip evacuation space

• Sharp cutting edges for reduced cutting force

• Improved surface finish during rough machining

These tools are ideal for high speed CNC machining of aluminum components in automotive and aerospace industries.

Color coated roughing end mills are designed to enhance tool performance and durability.

The advanced coating technology provides:

• Improved wear resistance

• Higher heat resistance

• Reduced friction during cutting

• Longer tool life

Different coating colors help identify tool applications and improve machining efficiency in industrial environments.

Common coating options include:

• TiAlN coating

• AlTiN coating

• Nano coating technology

Q1: What is a roughing end mill used for?

A1: A roughing end mill is designed for high efficiency material removal during rough machining operations.

The serrated cutting edge breaks chips into smaller pieces, reducing cutting resistance and improving chip evacuation. Roughing end mills are widely used in CNC machining of steel, stainless steel, and aluminum.

Q2: What is the difference between a roughing end mill and a finishing end mill?

A2: A roughing end mill is used for rapid material removal in the early stage of machining, while a finishing end mill is designed to achieve a smooth surface finish and precise dimensions in the final machining process.

Q3: Can roughing end mills be used for aluminum?

A3: Yes. Specially designed roughing end mills for aluminum feature sharper cutting edges and optimized flute geometry.

These tools provide better chip evacuation and reduce cutting force when machining aluminum alloys.

Q4: What are the advantages of coated roughing end mills?

A4: Coated roughing end mills offer improved wear resistance and heat resistance compared to uncoated tools.

Advanced coatings such as TiAlN or AlTiN reduce friction during cutting and significantly extend tool life in demanding machining conditions.

Q5: What materials can carbide roughing end mills machine?

A5: Solid carbide roughing end mills are suitable for machining a wide range of materials, including:

•Carbon steel

•Alloy steel

•Stainless steel

•Aluminum alloys

•Titanium alloys

Q6: Do you provide custom roughing end mills?

A6: Yes. Dohre CNC Tools provides custom carbide roughing end mills based on customer drawings or machining requirements. Our engineering team can design specialized tools to improve machining efficiency and tool life.
