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. 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.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
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.
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.
