How to choose different cutting edge milling cutter?

When selecting milling cutters with different cutting edges, there are several factors to consider, including the material to be machined, machining requirements, and machine performance. Here are a few key points to help you choose the right milling cutter blade:

• Type of cutting edge

Straight tooth milling cutter
Scenario: Suitable for machining relatively hard metal materials.
Characteristics: High strength of the cutting edge, smaller chip space, suitable for light milling and milling of hard materials.
Helical tooth milling cutter
Scenario: Suitable for machining relatively soft materials.
Characteristics: Uniform cutting force distribution, reduced vibration, suitable for deep grooves and long cutting paths.

• Number of cutting edges

Rough Tooth Milling Cutter
Scenario: suitable for rough machining.
Characteristics: Small number of teeth, large chip holding space, suitable for large depth of cut and large cutting volume.
Fine Tooth Milling Cutter
Scenario: Suitable for finish machining.
Characteristics: more teeth, small chip space, suitable for small depth of cut and small feed machining, and can obtain high surface finish.

•  Cutting Edge Angle

Large cutting edge angle
Scenario: Suitable for machining hard materials.
Characteristics: High edge hardness, high cutting force, suitable for efficient machining of hard materials.
Small cutting edge angle
Scenario: Suitable for machining soft materials.
Characteristics: Sharp edge, low cutting force, suitable for fine machining of soft materials.

•  Coating type

Uncoated milling cutter
Scenario: Suitable for machining general materials.
Characteristics: Low cost, suitable for regular machining.
Coated Milling Cutter
Scenario: Suitable for special materials or demanding machining.
Characteristics: Improve wear resistance, hardness and cutting performance, and extend tool life.

• Cutting Edge Materials

High speed steel milling cutter
Scenario: suitable for general milling machine.
Characteristics: moderate hardness, lower cost, suitable for general machining.
Carbide milling cutter
Scenario: suitable for CNC machining centers.
Characteristics: high hardness, strong wear resistance, but poor impact resistance, suitable for high-precision and high-efficiency machining.

•  Cutting edge shape

Spherical Milling Cutter
Scenario: Suitable for milling curved contours and round surfaces.
Characteristics: High cutting quality, suitable for machining thin-walled workpieces.
T-slot milling cutter
Scenario: Suitable for machining T-slots and V-slots.
Features: High precision, but easy to break, suitable for precision machining.
Woodworking Milling Cutter
Scenario: Suitable for machining wood, plastic, aluminum and other materials.
Characteristics: sharp edge, but the precision is lower than metal milling cutter.

• Summarize

When choosing milling cutters with different cutting edges, it is necessary to comprehensively consider the characteristics of the processed material, processing requirements, machine tool performance, and cost and other factors. By reasonably selecting the type, number, angle, coating and material of the cutting edge, the machining efficiency and machining quality can be improved and the tool life can be extended.
