Ceramic insert, Ceramic Cutting Tools

Description: Ceramic grade tools are typically classified into three general
categories: oxide, nitride, and matrix ceramics.
Oxide ceramics are alumina-based and are generally used in roughing and
finishing applications of the cast and gray irons. Increasingly, oxide
ceramics are being used in dry machining applications at high speeds. This
is due to the advancements within materials science, including the
incorporation of whisker-based materials.
Nitride ceramics exhibit extremely high fracture toughness and are used for
roughing and semi-roughing of cast irons under harsh conditions, such as
when there is considerable starting and stopping that would typically
increase fracturing.

CMCs contain ceramics mixed with other hard materials like cemented and
titanium carbides. They can also contain reinforcing whiskers and other
materials to increase wear resistance and toughness under hot machining
conditions. These are commonly referred to as SiC-whisker reinforced.
Alumina reinforced with SiC whiskers is the toughest and most resistant to
thermal shock of the oxide-based ceramics due to the extremely high tensile
strength of the SiC whiskers. It offers the additional benefit of being able
to be run without coolant, thus making dry machining a common application
while also being able to offer an increase in machining rates up to 800%.

Applications of Ceramic insert, Ceramic Cutting Tools :
Auto parts processing
A series of parts such as milling cylinder cover, cylinder sleeve, and
automobile brake disc are processed with composite silicon nitride ceramic
blade, which can improve the efficiency. For example, a milling cutter can
increase its speed from 92r/min to 275r/min.

Bearing machining
The rolling bearing adopts the technology of rough, fine, quenching, rough
grinding, and fine grinding for a long time. For example, after hardening to
63HRC, the blank of the GCr15 precision forging bearing will be deformed and
uneven and will get stuck in the rough grinding of the automatic grinding
machine directly, and even burn the spindle of the grinding machine in
serious cases. The finishing process of the bearing ring before quenching
and the rough grinding process after quenching are combined into the
finishing process of the ceramic cutter after quenching, which will make the
workpiece fully meet the required size and geometric accuracy, realize the
substitution of grinding by car and greatly improve the processing
efficiency.

Hard cast iron processing
If the composite nitride ceramic tool is used to process the cold cast iron
roll, the tool life is increased four times than that of cemented carbide;
it can be used to process superhard nickel alloy spray welding roller
bushing, which can greatly improve the cutting efficiency and speed, save
time and cost and improve economic efficiency.

Other fields
In the fields of machinery, metallurgy, mining, railway locomotive,
aerospace, precision instruments, molds, etc., the technology can be
reformed by using silicon nitride ceramic cutting tools to greatly improve
production efficiency, save energy and reduce cost.

Advantages of Ceramic insert, Ceramic Cutting Tools :
Compared with carbide cutting tools, silicon nitride ceramic cutting tools
have obvious advantages, which are shown in the following aspects.
● The HRA value of silicon nitride ceramic cutter is usually 91-93 (HRA is
used to represent the hardness index of soft and hard materials), so it has
good wear resistance and can be used to process high hard materials that are
difficult to be processed by traditional tools or cannot be processed at
all, such as various kinds of hardened steel and hardened cast iron with the
processing hardness up to HRC65 (60HRA = 20HRC).
● It can be used for rough and finish machining of high hardness materials,
as well as for high-impact machinings such as milling, planning, and
intermittent cutting.
● The cutting tools made of silicon nitride ceramics can be cut at high
speed to realize the function of “milling for grinding” for high hard
materials, simplify the processing technology and improve the processing
efficiency, so as to save time, electricity, number of machine tools and
plant area and other effects.
● The silicon nitride ceramic blade has less friction with metal when
cutting, which makes it difficult to stick to the blade and the roughness of
the workpiece is low.
● The tool’s durability is several times or even dozens of times higher
than that of traditional tools, which reduces the number of tool changes
during machining, ensures the uniformity of the workpiece, and also ensures
small taper and high accuracy.
● The cutting tool consumes the most abundant element silicon in the crust
as raw material, which can save a lot of strategic metal materials such as
tungsten, cobalt, and titanium.
