STX-4001 is a CE certified large precision diamond wire cutting saw.  It is designed to provide the smooth cutting or slicing for all kinds of materials (especially for larger size crystals, such as Si, CaF, glass, and sapphire, etc.) with the diameter up to 40″ (1000 mm).  It cuts the sample by a diamond impregnated wire (0.28 mm diameter) which moves back and forth repeatedly with the help of a digital controller.


Power Supply AC208-24 VAC, 50/60 Hz, 6000W, Single Phase
Cutting Speed  0.05 – 100 mm/ minute adjustable
Wire Moving Speed 0 – 5 Meter/ second variable
Controller 6″ color LCD touchscreen control unit allows you to set the program to control the Moving Speed of the diamond wire, feeding speed of the sample stage, the slicing thickness, and coolant pump operation.
Sample Stage The sample stage can move in the X-axis and rotate towards two directions (clockwise and counter-clockwise) for precision orientation. Max. Load Capacity: 1500KG
Diamond wire Ø 0.65mm x  400 m Length
Cutting Area Ø1000mm × 1000mm
Wire Tension Built-in pneumatic valves can easily adjust the tension of cutting wire. (air pump with >20 PSI pressure is required, but not included)
Cooling Circulating water/coolant system by two water pumps (included)

Warranty One years limited, not include the diamond wire and rusty parts
Certification CE Certified. With additional certification fee, MTI can arrange NRTL to perform UL/CSA inspection and label the machine per customer’s request.
  • It is required to use proper cutting fluid with the saw to prevent corrosion of the machine components. We strongly recommend you use oil based coolant or lube cool lubricant with the water. Do not use tap water directly, rusted component is not part of the warranty.
  • Never cut any materials without the use of proper cutting fluid. If you do so, serious damages can be caused to the spooler driving mechanism. 
  • For cutting the sticky materials such as non-ferrous alloy, epoxy, and plastic, you must sharpen diamond wire frequently. We suggest that cutting sample along with the included dressing stone (Glue sample and the dressing stone side by side and cut them together, this process will help keep the wire sharp enough for efficient cutting.  
  • Please clean the machine after the completion of each use.
