Product and technical questions only — selection, diameters, speeds, hammers, joints and maintenance. Sourcing and solution questions are answered on the solutions site.
Where an answer depends on a value KEENOVA has not released, we tell you what we need from you instead of giving a figure that would not apply to your conditions.
Start from the stone, not from the wire. The four inputs we need are the stone type and how abrasive it is, the cut length and face height, the machine and its power, and whether the cut runs wet or dry. From those we set bead diameter, beads per metre, bond and reinforcement together — changing one of them on its own usually moves the problem somewhere else rather than solving it. See the parameter checklist for what to collect before you ask.
Diameter is fixed first by the machine — the drive wheel and guide wheels have to take it — and then narrowed by the stone and the loop length. Tell us the machine model, the wheel sizes and the cut length and we will give you the diameter that fits the machine, with the bead specification to match. Diameter on its own does not tell you what output you will get.
Both are run on the same machines; the choice turns on the stone, how much water you have at the face, and how much the cut is allowed to wander. There is no answer that holds across all quarries, so we recommend against your own conditions: stone, machine, water supply and cut geometry. Send those and we will say which we would run and why.
A joint that fails early is usually a fitting problem or a loop-length problem rather than a wire problem. To tell which, we need the crimping tool and the pressure used, the loop length, the stone, and where in the cut it failed. A photograph of the failed joint helps more than a description. Send those and we will work through it with you.
Both models are published with the same working envelope, so the choice does not start from the wire speed. 55kW Quarry Wire Saw — 75kW PM Motor Quarry Wire Saw. Identical on both: Control: PLC + Vector Inverter
Dimensions: Approx. 212 × 170 × 197 cm
Flywheel Holder: 360° Rotation
Wire Speed: 0–40 m/s
Wire Tension: Stepless Adjustment. Where they differ: Machine Weight: Approx. 2,800 kg (55kW) vs Approx. 3,000 kg (75kW)
Main Motor: 55kW (55kW) vs 75kW (75kW). Send us the stone, the cut length and the machine you intend to run it on — we will tell you which one the numbers actually point to.
Wire speed for granite is set against the machine's power and how abrasive that particular granite is, and it is trimmed on the face rather than fixed on paper. Give us the machine model, its power and the granite you are cutting, and we will tell you the range to start from and what to watch as the cut develops.
Hammer size follows the hole diameter and the compressor you have, not the rock on its own. Send us the hole diameter and depth, the compressor capacity and working pressure, and a description of the rock, and we will match hammer, bit and rod as one set.
The bit is specified after the hammer: the shank has to match the hammer, the face shape follows how hard and how fractured the rock is, and the button grade follows how abrasive it is. Give us the hammer model, the hole diameter and the rock, and we will specify the bit with it.
In hard rock the hammer, bit and rod have to be matched as one set — rod taper and bit diameter to the hammer, button grade to the rock. Tell us the rock, the hole diameter and depth, and the compressor you run, and we will put the set together.
Dress the wire when it stops cutting freely, not on a fixed schedule — the signal is a fall in cutting rate or a change in how the machine loads. If you record cut rate and wire consumption per square metre you will see the point on your own face. Here is the recording method we use.
The gain is usually in the setup rather than in the wire: loop length, alignment of the guides, water reaching the cut, and whether the machine is running in the range the wire was specified for. Send us your current wire specification, the machine and the figures you are getting, and we will tell you where the loss is.
Whether the item is a stock specification or has to be made to one, the quantity, and the shipping method you want. Tell us the model and the quantity and we will give you a date rather than a range.
Yes. Machines, diamond wire, tools and the consumables that go with them can be shipped as one order, which also keeps the documentation and the container to a single set. Tell us what you need and we will quote it together.
We support the specification after the sale: help with set-up, with diagnosing a wire or tool that is not performing as expected, and with choosing the replacement when your conditions change. Contact us with the machine, the product and what you are seeing, and we will take it from there.
We start from your conditions and recommend against them, rather than quoting from a list — the specification comes before the price. If the honest answer is that a different tool suits your stone better, that is what we will tell you.
Send it with your conditions. If it belongs on this site we will add it; if it is a sourcing question we will point you to the right place.
