Milling processing in the metal processing industry

Milling is the most common and mature method of processing in the metalworking industry. With the clarification of various processing requirements, more and more tools with various characteristics for various milling operations, as well as various new milling methods, have been continuously developed.

Coromant: Introducing a new solution

In May of this year, the International Association of Mould Industry and Special Purpose Tools (ISTMA) designated Sandvik Coromant as its global partner and became the organization's first cutting tool supplier, which also illustrates the milling of Sandvik Coromant. The position of the program in the mold industry. Recently, the company has introduced new milling tooling solutions.

The company's latest generation of GC4220 is hailed as “widening the boundaries of steel milling performance.” Compared to the current best grades, the GC4220 is able to increase productivity by 20 to 30% over its application, making it ideal for the mold industry. Semi-finishing and roughing milling. It has an improved matrix and coating and provides the high safety and predictability required for maximum productivity and high metal removal in steel applications at high temperatures (due to high speed milling and hard materials) , it still has good performance. Improved edge strength and toughness provide the ability to apply high cutting parameters while also providing high predictability in dry, face milling and copy milling applications, ensuring good surface quality.

Another notable mention is the high-precision tool CoroMill 490, which is suitable for applications with small depth of cut and less final machining, such as high-precision forgings and castings close to the final shape used in machine shops. High production efficiency. The amount of work required to process these forgings and castings is small but more precise. The CoroMill 490's four-blade insert design is now also available, which has a low cutting force that makes the cutting light and quiet, allowing for smooth cutting into the workpiece. This significantly reduces the cost per piece for the customer. For these applications, the CoroMill 490 is the most effective tool. It is so precise that it can be produced in one go. The maximum depth of cut is 5.5mm (4mm is recommended).

CoroMill 490

CoroMill 490 allows customers to use higher cutting parameters, starting values ​​for higher productivity in production, and the versatility allows customers to use CoroMill 490 as a standard milling tool instead of multiple tool stocks. Simplified production control. The result is reduced machining costs for face milling and square shoulder milling. CoroMill 490 can also be used for contouring and edge cutting without the presence of knife marks.

Kenner: New milling cutters increase production

At the ongoing IMTS2008 Chicago show, Kennametal launched innovative solutions in turning, milling and more. Among them, the Z Plung milling cutter for milling is designed for aerospace, mold and general engineering equipment. Its unique design makes the chip removal smoother, the milling groove processing performance is more prominent, the new milling cutter can increase the production capacity by at least 30%.
