Indexable and micro tool products for the automotive aerospace medical energy and pcb industries.
Ceramic tools for machining.
This generates a material that is chemically very stable but which lacks thermal shock.
New ceramic insert grade for efficient and reliable cast iron machining with excellent wear resistance and reduced heat at the cutting edge.
Ceramics can be made from several different types of hard metal oxides or nitrides.
That facilitates the removal of material and a reduction in cutting forces.
With reinforced ceramic cutting tools the objective in machining is to generate high temperatures ahead of the cutting tool to soften or plasticize the workpiece material.
There are a range of ceramic grades available for a variety of applications.
Oxide ceramics are aluminium oxide based al2o3 with added zirconia zro2 for crack inhibition.
I used macor in applications where it had to withstand moderatly powerful laser hits and remain white.
If you do machine macor wear breathing protection.
Carbide cutting tools for milling turning and holemaking cnc operations.
So too can carbide and ceramic cutting tools achieve higher speeds regardless of the workpiece material than do ones made of high speed.
All ceramic cutting tools have excellent wear resistance at high cutting speeds.
Following a final firing when as fired tolerances are not sufficient fine diamond machining grinding using diamond impregnated cutters is often required.
The ideal cutting temperature in nickel alloy is about 1 800 degrees f for example.
This chart shows the relative strengths of various insert shapes.
All cutting tools have a recommended cutting speed for any given material.
The technical properties of typical ceramic tools are indicated in table i applications of ceramic cutting tool materials cast iron machining machining of cast iron brake drums and discs for the automotive industry remains the largest application area for ceramics and all three categories of ceramic can be used depending upon the application.
It starts with round on the outside edge being strongest and moves to 35 which is the weakest.
Fine diamond machining full density parts ceramic parts fired to their full density are too hard for machining with tool steel cutters or even conventional methods.
Ceramic cutting tools are becoming more and more popular with rise in demand for higher productivity improvement in machine capabilities and growth of automotive energy and aerospace markets.
I have used a white colored ceramic called macor which can be machined even with hss tools although it does wear them away a bit faster than tough steels.
But the tool tip generally carries much of the stress.
Cutting with reinforced ceramic inserts put a strain on the tool holder and machine.
