LMT Onsrud's MXR and HXR End Mills Engineered for Machining Inconel
LMT Onsrud LP’s MXR and HXR end mills are designed to meet the challenges of machining Inconel and other nickel-based materials.
LMT Onsrud LP’s MXR and HXR end mills are designed to meet the challenges of machining Inconel and other nickel-based materials. Both tool series are coated with EnduraSpeed for better tool life and performance.
The MXR series has been engineered for heavy profiling, allowing for 15 percent radial engagement during machining. The optimized variable geometry delivers high material removal rates along with a quality surface finish. Tools are available with four or five flutes and with multiple corner radii. A four-flute ballnose version for contouring is also available.
Configured in seven-, nine-, or 11-flute options, the HXR end mill line also provides material removal rates and has been developed for lower radial and higher axial engagement for high-efficiency machining (HEM). Longer tool lengths incorporate a chipbreaker design to enhance chip removal and thereby increase tool performance.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
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.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
