A Quick Comparison between CVD & PCD Diamond Tools
When it comes to material machining, cutting or tooling,
nothing is more challenging and harder than tooling diamond. Under the accurate
machining circumstances and in various nonferrous applications, diamond easily
outlasts ceramic, tungsten carbide, high-speed steel, and polycrystalline cubic
boron nitride. As we all know, this specific does have downsides shortcomings,
for example, it is unable to machine ferrous substances, but when the
application entails high volumes, super-speeds, or resources like graphite or
aluminium; a diamond can be an idea and most effective device to bring into
play.
Whenever, an application necessitates tooling, users or
machinists usually get two options:
1.
Poly-Crystalline Diamond (PCD)
2.
Chemical Vapour Deposited (CVD) Diamond
While PCD tools like PCDBoringbare and PCD End Mill are
veteran players in this field; CVD tools are relatively new for this
application. However, both devices have their own set of advantages and drawbacks
and are called for various applications, under different circumstances.
●
PCD: A Verified Performer
PCD devices offer the strength, inflexibility, and strong
abrasion confrontation features to the natural diamond without representing its
vulnerability to fracturing to the application. Basically, these tools are
designed manufactured with the help of man-made diamond elements which are
brought up together in a high temperature and high-pressure process. During
this process, the particles are integrally linked to a lined tungsten carbide
intrinsic for the confrontation of motorized strength and crash.
●
PCD Applications
PCD is compatible with high-speed
machining and cutting of aluminium, especially when finely polished surface
finishes are compulsory. Alongside this, during the machining of the highly
sharp workpiece, PCB tools like PCD Boringbare and PCD End Mill are
also required.
Generally, PCD is suggested for
machining and cutting strong and high-content materials and silicon aluminium
alloys. Apart from this, it is also used for machining and cutting other strong
materials like brass, carbide, copper, and bronze in various applications
including turning, milling, profiling, boring, grooving, and Holemaking.

CVD Tools: The Neophyte /
Chemical Vapour Deposited or CVD diamond tool is an
extremely strong, abrasion-resistive, and pure diamond material device which
requires no binder to be used. As an alternative, diamond is put down in any of
two forms i.e. thick-film diamond or thin-film diamond. CVD Thick Film Diamond
is laid down as a rock-solid, free-standing wafer and eventually machined to
required size while the thin-film diamond is encrusted onto carbide CVD Insert
and gyratory instruments.

CVD Applications
The most promising application of CVD instruments like CVD Insert with Chip Breaker, CVD End Mill, CVD Thick Film Diamond, and CVD Boringbare has been machining of
graphite. But currently, there is a rise in CVD tooling for various other
machining applications for the nonferrous materials like plastic, metal, and
composite usage. In simple terms, the newcomer CVD is well-suited to almost all
kind of nonferrous metals and can deliver flawless finishing and outcomes
regarding the intervallic cuts of super-strong materials like high silicon
aluminium, copper, brass, carbides, and carbon fibre materials.
