For bench cutting in marble quarries in India, diamond wire saw (DWS) machines are mainly used. The cutting performance of the DWS machine,
or diamond cutting tools depends on non-controllable
parameters related to rock characteristics and controllable parameters related to machine and other operational
aspects. Cut size area of a bench is one of the operational controllable parameters and it has an important role in
the cutting performance of the machine. Dolomitic marble deposits are available in large quantities in India. Thus,
this study was undertaken to investigate the effects of bench cut size area on the cutting performance of DWS
machines in soft, medium-hard and hard dolomitic marble. The study revealed that cut size of the bench plays a
significant role in the performance of the DWS machine. The optimum bench cut size also varies with the nature of
marble to be cut. It also depends on the types of cuts to be made in the marble such as vertical, vertical strand
and horizontal. The results of this study can also be applied to other types of marble and they will also be of use
to the operators of stone quarry machine.
Stones exploited from mines by rock driller
with irregular form and rough section are called raw stones, which can not be applied in plate processing
immediately. At present, raw stone in China mainly involves marble and granite. With the development of technology,
the old way of shaping stones by labor is outdated.
Diamond saw blade used to process raw stones usually owns a large circular saw blade, on which diamond
grits are inserted. Owning to its flexible property, diamond wire
saw blade can be used to process ultra-hard stones. However, its diameter is usually large, and its height is
twice the stones to be processed together with the diameter of Flange. It is not easy to produce diamond saw blade
with too large diameter. Therefore, diamond saw blade is unsuitable to process oversize plates.
Comparatively, diamond wire saw not only owns the flexibility of ropes, but also owns rigidity of
diamond. Moreover, they are not limited by length. Due to those features, diamond wire saws are almost applicable
to cut any large objects. It has many advantages, such as short time preparation, strong flexibility, high
efficiency, energy saving, etc, which make diamond wire saws popular in stone mining and stone processing.
Plate Cutting
When processing stones, plate cutting is a quite important step. Usually diamond saw blades are used to cut
plates. But in this situation, the size of plates is relatively small. One diamond wire saw is able to cut large
plates and ultra-large plates, and is not restrained by the thickness of stones. However, compared with diamond
frame saws containing several tens or a few hundreds saws, diamond wire saw is neither efficient nor cost-
effective. Consequently, diamond wire saws are used when plates are too thick or their amount is small. With the
development of technology, combined diamond quarry wire saws are went out. Combined diamond wire saws can be
applied in cutting marble and granite plates when changing different beads or linear velocity of diamond wire saws.
Irregular Stones Processing
Irregular stones refer to all special-shaped stones except sheet and block stones, and include many types, such
as pillars and arches. Nowadays, people’s demands are much stricter, so it is with irregular stones processing. In
the course of irregular stones processing, diamond wire saws and diamond saw blades are used. Owing to its high
linear velocity, diamond wire saws could shift curve type and arc type, and can be widely applied in processing
parquet and curved sides.
Concrete wire sawing is a versatile and effective concrete sawing tool used for particularly challenging
projects where traditional saws won’t work. When cutting through concrete structures, cross-sections, and other
complex objects, manual saws are often unable to do the job effectively—when those situations arise, wire saws can
get the job done. Once set up, wire saws can easily saw through any concrete, stone, or metal structure.
A concrete wire saw consists of a thin steel wire with diamond segments embedded that cut through hard
materials via abrasion. The wire is threaded through a system of pulleys that are aligned in the direction of the
cut. Once the wire is securely wrapped around the object, the pulley pulls the wire across the concrete and begins
cutting. Water is fed across the system to keep the wire lubricated and the system from overheating from extreme
friction.
WHEN IS Quarry Wire Saw NECESSARY?
If you have a difficult construction project that involves cutting through steel-encased concrete, concrete-
encased steel supports, concrete retaining walls, or reinforced rebar, wire saws can saw through them safely and
with ease. Due to its diamond cutting edge, wire saws are ideal for segmenting or removing large chunks of
reinforced concrete when other saws can’t cut through the strong material. Stone cutting wire saws can also be configured to tackle unique structures
such as steel nuclear reactors or metal engine blocks.
THE BENEFITS OF WIRE SAWS
There are several reasons why conventional diamond saw blades won’t work for a concrete cutting project: the
concrete structure may be too large, the shape may be too irregular to safely work around, the location may be too
inaccessible, or the structure may be too heavily reinforced for blades to cut through. Wire saws are easily able
to navigate all of those problems. The benefits of using wire saws for concrete construction projects also
include:
Cleaner construction areas. Since water needs to flow across the wire saw to keep concrete
dust from building up and damaging the equipment, this process produces much less airborne dust than traditional
saws. Not only does less dust make the construction area easier to clean up, but it also keeps workers from
inhaling concrete particulates
Deeper concrete cuts. Traditional cut-off machines, diamond chainsaws, and circular saws have
a limited reach. Concrete cutting wire
saw offers an almost unlimited depth range for concrete cutting.
Precision cutting. Since the wire is more narrow and flexible than ring saws, concrete cuts
will be more precise using wires. And since the wire is guided through pre-cut drill holes, the final cuts will
always be the right size and in the right location.
Easy access. Wire saws don’t require as much space to operate as ring saws do. And since they
aren’t manually operated, it’s an ideal option for construction jobs that have hard-to-reach places and are in
challenging environments like underwater.
Quiet. Wire saws cause minimal vibrations and are much quieter than other construction
equipment. This low noise output makes it the preferred cutting option for residential projects and night
operations.
Quick cutting. Since wire sawing doesn’t require manual operators, the machine can cut at a
consistent speed without breaks. This keeps construction projects running on schedule.
Increased safety. Because wire saws are remote control operated, it minimizes the risk of an
accident and keeps everyone near the construction site safe.
PROBLEMS WITH CONCRETE WIRE SAWS
Just because wire saws are remotely operated doesn’t mean there isn’t a chance of injury. Since the wires are
under extreme tension, there is always a chance that they can snap and cause extreme injuries to anyone nearby.
Construction teams should still take proper safety precautions when using this piece of machinery. Just like any
large piece of machinery, only trained specialists should operate wire saws with
dry cutter.
