Turning of Zirconia
Are you interested in lathe machining of zirconium and its alloys from the vendor — company Electrocentury-steel? Here you will find only reliable information on this issue
The company Electrocentury-steel offers to acquire affordable rental and semi-finished products of zirconium and its alloys. Supplier guaranteed prompt delivery of products at any address specified by the consumer.
Some mechanical properties of Zirconia, which determine its machinability on machine tools:
- Tensile strength tensile, MPa — 240;
- Shear modulus, MPa — 190;
- Poisson’s Ratio Is 0.35.
Zirconium can be machined on machine tools of conventional methods. For all operations you must use three main parameters:
- The speed of rotation of the workpiece;
- Considerable feed of the cutting tool;
- Intensive supply of lubricating-cooling mediums (mostly with low viscosity).
For mechanical processing of zirconium in the pre-treated surface, the angle of filing and sharpening of the cutter determines the quality of the execution of the turning operation.
Satisfactory results can be obtained with tool made of hard metal and tools made of high speed steels. In the first case, provided a better surface quality and higher productivity. Polishing or honing the cutting edges of the tool provide a high resistance. Zirconium semi-finished products after turning have excellent finish, requiring relatively material and labor costs compared to turning of alloy steels.
Buy billets and semi-finished products of zirconium and its alloys at cost-effective prices, the company offers Electrocentury-steel. The supplier ensures prompt delivery of metal in any item set by the client.
Since the attached for turning the forces and moments is relatively small, should be timely to eliminate causes for the spontaneous ignition of zirconium workpieces. Since zirconium is turning very hot, its dimensions increase, which may adversely affect the reliability of clamping the workpiece in fixtures the lathe.
Good results are processes vertical and horizontal milling flat surfaces. Milling of zirconium is performed at the maximum values of the setting angles of the cutter and the maximum cutting depth.
In the preparation of metal-cutting tool, special attention is paid to the quality of the cutting edges of the cutters. Use positive axial angles for both sides of the recess.
Optimal surface finish and tool life are obtained when the grinding angle of the cutting tool is in the range of 12 …15 °. In the treatment area must always be a sufficient amount of cutting fluid.
Turning of Zirconia is much less energy-intensive: only 10 percent of the energy is absorbed by the cutting surfaces of the cutting tool.
When grinding Zirconia are usually established tolerances for final processing. Metal (both pure and alloys) can be easily surface grinding, cylindrical grinding, centerless grinding and belt grinding.
For processing, you can use normal as abrasive wheels, abrasive materials and lubricants. The use of lubricating-cooling media improves the quality of processing, high performance and also prevents ignition of the workpiece from accumulating chips.
Zirconium produces a white stream of sparks.
Cutting speed and choice of the tool material determines the efficiency of the CNC cutting zirconium blanks. The normal speed of rotation is 2500…35000 min-1.
