Precision Wire Saw with Sample Stage and Diamond Wire – 12″ Dia Cutting Capability – NST-1202


Available on backorder


Available on backorder


The STX-1202 precision reciprocating type diamond wire saw uses diamond impregnated wire (0.3mm dia.) for cutting all kinds of materials (especially for larger size crystals, such as Si, Ge, and GaAs, etc. with boule diameter up to 12″ (300 mm) and leaves a smooth cutting surface. Y and Z axis and the rotary sample stage are all driven by the stepper motors which provide the precise, stable and varied cutting of the samples. The cutting program can be set in the touch screen controller which includes the feeding speed, cutting depth, width, slice number, etc.

Power Supply AC 220 V, 50/60 Hz, 350W    (110V available upon request)
Frame Material Heavy duty Aluminum alloy
6″ color LCD touch screen control panel
program to control the Moving Speed of the diamond wire, feeding speed of the sample stage, the slicing thickness, and coolant pump operation.
Three axles Sample Stage
(All three axles are driven by the stepper motors and can be defined in the cutting program.)
  • Z axle moves the diamond wire up and down.
    • Z down(cutting/feeding): The diamond wire moves down toward the sample stage.
    • Z up(backing): The diamond wire moves up and away from the sample stage.
  • Y axle moves the sample stage in and out (defining the cutting width). Multiple cuts with the same width can be set.
  • R axle rotates the sample stage horizontally.

Maxium Sample Dimensions Ø300mm×300mm
Wire Tension System
  • Built-in pneumatic valves can adjust the tension of cutting wire. (air pump with >20 PSI pressure is required, but not included)
  • Optional: Digital Pressure regulator 0~130PSI (+/-3% full span accuracy, see Pic below right)


Cooling System One Coolant tank and two small immersion pumps are included for cooling and lubricating diamond wire ( only use anti-rust liquid and oil as a coolant, never use water )
Meteorite Sample

  • Swing & Rotation Sample Fixture: Such fixture needs an independent controller for its parameter settings such as swing frequency/ angle (±23°, up to 20 swings/min), rotating speed and rounds (30rpm max.) Higher cutting surface quality can be expected by swinging or rotating the specimen throughout the cutting process. Please click Pic.2 &3 and video to learn more details.   The fixture will enhance cutting speed up to 2 times

Application Notes
  • An air compressor is necessary for operating the STX-1202 Wire Saw, please order from the relate product below.
  • The flow rate of coolant is adjustable by the valve in the blue feeding tubing. Please adjust it properly to improving cutting performance.
  • Wire saws applications
  • 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, otherwise, the rusting 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 by 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.
