- chemical vapor deposition ( CVD)
chemical vapor deposition ( CVD)
High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.
- flank wear
Reduction in clearance on the tool’s flank caused by contact with the workpiece. Ultimately causes tool failure.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
Tungaloy’s CVD grades in the T9200 series offer outstanding performance in steel turning. This new generation of grades features Tungaloy’s innovative PremiumTec post surface treatment technology making T9200 hard to break.
- A newly developed hard coating layer, with a high resistance to flank wear.
- Thick Al2O3 layer with excellent resistance to high heat and crater wear, especially effective for high-speed machining.
- New cemented carbide substrate exclusively designed for T9200 series drastically reduces defects in alloys, which greatly improves fracture resistance.
The new T9200 grade series provides long and stable tool life, reduced machine downtime and cost reduction.
