Customer Case
Quarry Wire Saw Machine in China
Huada shipped this quarry wire saw machine to Henan, China, for stone mining. The saved technical description centers on permanent-magnet drive behavior under changing frequency and voltage, rather than on a particular stone or production result.
Starting torque and cutting travel
The motor is described as providing constant torque over its frequency range, with strong torque at low frequency to make starting easier. Once cutting begins, machine travel and wire tension still have to suit the contact length, stone and pulley route. None of those site settings is present in the archive.
Voltage variation at a quarry
The source highlights safe use where voltage varies and says the energy-saving drive may allow more wire saws without expanding the mine's power-supply system. That is not an electrical capacity calculation for the Henan site. Simultaneous load, transformer capacity, cable distance and measured voltage must be checked before another machine is added.
What the Henan delivery does and does not show
The province, stone-mining purpose and drive technology are supported. The source does not identify granite, marble or another material, nor does it state the machine model, motor rating, wire or cutting output. Customer praise is qualitative.
A future acceptance record should pair the machine identity with the actual stone, bench geometry and electrical readings. Startup behavior, cut area, time and wire condition would provide the evidence needed to evaluate the drive in Henan rather than repeating a general product description.
