Easy-To-Handle Inserts Provide Cost Effectiveness
IMTS 2018: Ceratizit’s MaxiMill 491 is a series of double-sided, 90-degree shoulder milling inserts with eight useable cutting edges.
Ceratizit’s MaxiMill 491 is a series of double-sided, 90-degree shoulder milling inserts with eight useable cutting edges. The tools are designed for ease of handling and can be quickly changed inside the machine, reducing machine downtime. The inserts’ coating technology effects stable and soft cutting, making them suitable for most requirements. Positive insert geometry and good surface quality promote extended tool life. The eight usable cutting edges of the inserts also contribute to cost effectiveness.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
