TX-202A (STX-202A is an upgraded version of STX-202 since Mar 2014 with additional auto-control Y-axis) is a CE certified, small precision diamond wire saw for cutting sample ≤ 2″ diameter or square up to 50mm in thickness. It is designed to provide a smooth cutting for many kinds of materials, especially for  fragile crystals and TEM or IC sample by using  0.28mm diameter x 15-meter long diamond impregnated wire. It is an ideal cutting tool for material research, TEM sample preparation, and  IC failure analysis.

  • Wire Saw Control Consol: Universal 110V or 240VAC  50/60Hz, 200W max.

  • Heavy-duty aluminum alloy structure with compact size
  • automatically controlled Y-axis by the digital panel
  • single wire swing cutting with adjustable wire length from 5-15mm (broken wire still can be used)
  • Transparent plastic plates are included to prevent Coolant splashing
  • Add an oil refill cup behind the forming tube (New design), please apply 10-15 drops Anti-Wear Oil before first-time use.
  • Wire spooler motor, 3 Amps, Torque=1.8Nm

Controller & Touch Screen
  • Color touchscreen controller will set up wire travel speed, cutting speed along Z axis and cutting width along Y axis


Diamond wire
  • ≤ 15 meters used for each installation
  • One spool of 0.30mm Dia x 20 meter length Diamond Wire is included for immediate use
  • A Diamond Blade Dressing Stone is included for keeping the wire sharp.
  • Optional:
Wire tension system

  • Standard:  Steel spring wire tension system with break wire alarm
Water Pump
  • One water pump is included for cooling diamond wire during cutting. (the pump voltage is the same as the saw voltage)
  • You must use anti-corrosive oil or radiator water as coolant ( buy from any auto store )
  • Warning:  must clean the machine after each cutting, especially using tap water as the coolant to prevent rust.


  • 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
  • The flow rate of coolant is adjustable by the valve in the blue feeding tubing. Please adjust it properly to improving cutting performance.
  • Please use correct cutting fluid. Don’t use tap water or any other fluid would cause corrosion of machine parts.
  • Must clean the machine after each use.
  • 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, the rust component is not part of the warranty.
  • Do not overflush the sample stage, it may rust the Z-axis step motor.
  • It is required to apply 10-15 drops Anti-Wear Hydraulic Oil (ISO 32) using an oil can(#19)  before first-time use or continue working for 150 hours.
  • And limited amount of grease (general purpose grease will do) should be added to the motor shaft periodically,
  • 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.
