The company’s Form-A-Groove tooling can generate complex profiles in a single plunge. They are said to simplify programming, increase production and free tool locations for other tools. The tools consist of combinations of simple grooves or more complex combinations of grooves, arcs, angles and convex or concave radii. Tools can be composed of stacks of individual inserts or a single carbide block ranging to 2" wide. Available coatings include TiN, TiCN, TiAIN or diamond-film. Toolholders are available in 1" round and 1/2", 3/4" and 1" square for internal and external applications.
In addition, the company has expanded its selection of Groove ‘N Turn toolholders. The new toolholders are available in 3/4" and 1" square and are used for making undercuts and thread reliefs at a 30-degree/60-degree angle. The toolholders can be used on conventional, Swiss and CNC machines for grooving inserts in sizes ranging from 0.004" to 0.150". Inserts are available in three grades: D2 for steels, D5 for nonferrous and HSS. TiN, TiCN, TiAlN coatings are available as is a full selection of radius and special configurations.
UNCC researchers introduce modulation into the tool path. Chip breaking was the goal, but higher metal removal rate is an intriguing secondary effect.
Combining a rotating tool with rotating work produces a machining operation that is distinct from standard turning or milling.
The dynamics of chip formation and evacuation make grooving in turning operations unique in almost every way. Innovative insert designs and coatings can improve your grooving operation, but to be completely successful, there are some other things you should know.
