Tungaloy's TCL18 Chipbreaker Minimizes Cutting Forces with TetraMini-Cut Grooving Tool
The TCL18-style chipbreaker for Tungaloy’s TetraMini-Cut line of grooving inserts is designed to minimize cutting force.
The TCL18-style chipbreaker for Tungaloy’s TetraMini-Cut line of grooving inserts is designed to minimize cutting force. The chipbreaker is said to ensure light cutting action as well as good chip control when turning at low feed rates. The insert is coated in AH7025, a nano-multilayer PVD coating with high aluminum content that provides hardness and adhesion to the grade for better process security during grooving operations.
TetraMini-Cut features a compact grooving insert with four cutting edges. According to the company, the security of the insert clamping system contributes to repeatability, accuracy and more predictable tool life. The system’s insert clamping mechanism ensures secure insert retention and high repeatability, the company says, promising machining accuracy and more predictable tool life.
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.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
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.
