High grindability and long life cycle of vitrified wheel increase the quality and productivity enhancing competitiveness of customers.
▶ High Quality
Vitrified wheel has high precision and even amount
of grinding on both sides due to fixed abrasive grain without warping
(Adjustment of amount of grinding is available with speed adjustment for upper
and lower wheel). Also, polished products have excellent surface roughness with
reproducibility.
▶Stability
Workpiece with holes or grooves can be
polished without impact.
▶ Longer Lifecycle of Wheel
The more dressing is performed, the
shorter the lifecycle of the wheel is. However, SYD vitrified wheel has long
lifecycle due to high grindability.
▶ Cost and Time Saving
Polishing time is five time faster than
the existing resin bond diamond pellet wheel.
Also, it does not need multi-stage complicated ultrasonic hot water cleaning.
General cleaning is enough.
▶ Clean Working Environment
Abrasive is not used, so working environment can be
kept clean.
▶ Applicable Grit Size of Diamond and CBN
: #80 ~ #30,000
▶ Wide Range of Application
Most of materials including steel can be polished.
▶ Size
: available up to ø2500
▶ Usage of Application
Range of Application:
SYD vitrified diamond and CBN wheel can polish most of materials including
steel.
● Metal : Cast iron,
Tool steel = SKS, SUS, dies steel, SKD, structural alloy steel = carbon steel
S-C, SCM, SNCM, bearing steel, tungsten, carbide
● Ceramic : alumina, silicon, carbide● zirconia, boron carbide● Glass(sapphire) ● quarts
● ferrite ● aluminum ● copper, brass
CBN is boron nitride(BN) made from the
reaction between nitrogen and boron, a part of boride. It is also called
CBN(cubic boron nitride) due to cubic crystal structure like diamond.
Hardness is lower than diamond, but
diamond is worn after starting oxidation on 600~700℃ in the air. However, CBN is not oxidized on high
temperature of 1,370℃, and it does not react with iron rarely worn.
Therefore,
vitrified diamond wheel is mainly used for polishing non-heat treated products
including steel, and vitrified CBN wheel is mainly used for polishing
nonferrous metal and heat treat products.
