High-Speed Milling Grades Provide Durability, Reliability
Dormer Pramet has released their latest high-performance grades for milling hard materials.
Dormer Pramet has released the M4303 and M4310 high-performance grades for milling hard materials. The milling grades provide durability and reliability in semi-finishing and finishing applications.
Each grade is designed for high-speed milling in the die and mold sector, offering consistent wear and longer tool life. An ultra-thin PVD coating increases cutting edge toughness, while the substrate provides durability and strength, preventing fracture by chipping.
The M4303 replaces the previous 7205 grade and provides better wear resistance. Developed for hardened steel above 55HRC and cast iron, it can also be used for machining steels and nonferrous metals.
The M4310 replaces the existing 7215 grade and offers a balance between toughness and wear resistance in hardened steel and cast iron. It can also be used for machining stainless steel, steels and nonferrous metals.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Economic efficiency is an important consideration when choosing tools for challenging metals.
