What Is Welding Milling Cutter? – UKO Blog

The hard alloy blade is brazed with pure copper or other solder on the ordinary structural steel or cast iron toolholder to make a welding milling cutter.

What are the advantages or disadvantages of welding milling cutter?

• Advantages: The welding milling cutter has a simple and compact structure; good rigidity and strong vibration resistance; convenient manufacturing and sharpening; flexible use.
• Disadvantages: After high temperature welding, the strength and hardness of ordinary blades are reduced, and the cutting performance is reduced; ordinary blade materials produce internal stress and are prone to defects such as cracks; but cemented carbide blades can avoid the above situation due to their own material characteristics. ; But the time for tool change and tool setting is long, which is not suitable for automatic CNC machine tools.

What are the types of welding milling cutter?

• Cylindrical milling cutter: used for processing plane on horizontal milling machine. The cutter teeth are distributed on the circumference of the milling cutter. According to the tooth shape, they are divided into straight teeth and spiral teeth. According to the number of teeth, there are two types: coarse teeth and fine teeth. The helical coarse-tooth milling cutter has fewer teeth, high tooth strength and large chip space, suitable for rough machining; fine-tooth milling cutters are suitable for finishing.
• Face milling cutter: It is used to process plane on vertical milling machine, face milling machine or gantry milling machine. There are cutter teeth on the end surface and the circumference, and there are coarse and fine teeth. Its structure has three types: integral type, insert type and indexable type.
• End milling cutter: used for processing grooves and step surfaces, etc. The cutter teeth are on the circumference and end surface, and cannot be fed along the axial direction when working. When the end mill has end teeth passing through the center, it can feed axially.
• Three-sided edge milling cutter: used to process various grooves and step surfaces, with teeth on both sides and circumference.
• Angle milling cutter: used for milling grooves at a certain angle, there are two kinds of single-angle and double-angle cutters.
• Saw blade milling cutter: used to process deep grooves and cut off the workpiece, with more teeth on the circumference. In order to reduce friction during milling, there are 15’~1° secondary deflection angles on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail milling cutters, T-slot milling cutters and various forming milling cutters.
