Spark Cutter, Micro Diamond Saw, and Micro Hotplate
Spark Cutter - Model EE 4 
The EE 4 Spark Cutter (Electroerosion Unit) is designed for drilling holes, slots and discs of virtually any profile in hard meals. The cutting speed will, of course, vary depending on the sample size and material. As an example, a hole can be drilled in titanium sheet of 0.3 mm thick in about 20 – 60 minutes depending on the surface quality required.
Application
Because of the basic operating principle of the Spark Cutter, it is advised that the device can onlybe used for high-conductivity materials (with the exception of aluminum). The work piece holder accessory can hold 5 mm wide metal bands. Work piece of different size require modification of the holder.
Operation
Operation of the device is based on an electrochemical process. The drilling tool and work-piece are connected to the power supply: the positive pole to the work-piece, and the drill through an electromagnetic coil to the negative pole. By switching on the power supply, electric current flows through the circuit consisting of the work-piece, the electromagnetic coil and the drill. When the electric current exceeds a certain limit, the magnetic field of the coil lifts up the drill and the current is cut off. The drill is then forced back to the work-piece by a spring in the head unit, and the cycle starts again. The drilling is effected by the electrochemical process taking place at the moment that the electric circuit is stopped.

MicroSaw – Model MS 3
MS3 MicroSaw
MicroSaw is a small, versatile diamond wheel saw, to be mounted under a standard laboratory microscope. The precision offered by such an optical alignment makes MicroSaw ideal for cutting and sectioning required during the TEM specimen preparation. The compact design and easy operation, MicroSaw allows the user cut almost any solid material with precisely and reproducibly prior to thinning for TEM. Thin ceramic, semiconductor material, hard metals can be further sectioned with 0.01mm accuracy.
Operation
The Model MS 3 MicroSaw is driven by an electric motor through a helical transmission. The 12 V DC is provided by the power supply subunit. The speed at which the wheel turns is continuously adjustable. Adjustment of the specimen position, arm contact point, arm tension and the down-stop control mechanism is possible. Two adjustment screws at the bottom of the instrument allow positioning of the stand, and leveling the MicroSaw underneath of the stereomicroscopy for precision sectioning.

MicroHeat –
Model
MH2
Thermoplastic gluing under stereo microscope
- Heat stabilized
- Small
- Ideal for thermoplastic gluing
Application
MicroHeat is heat-stabilized, combined with a power supply, designed for embedding samples and for thermoplastic gluing under stereo-optical microscope. The MicroHeat was developed to make the embedding procedure easier. Because of MicroHeat is small dimensions, it is can be easily placed on the specimen table of the sterooptical microscope, and with the help of the microscope, the gluing faults can be avoided, this result is very important in case of sample requiring bubble-free sticking (e.g. cross section samples for EM).
Operation
Model MH 2 is relatively simple to operate. The temperature of the hot plate can be adjusted continuously in a wide range and is kept constant by the built-in electronic. A control circuit maintains the temperature of the heated surface within ±5°C. The temperature of the heated surface usually reaches the preset temperature within 1 – 3 minutes. However, it is recommended that to use the hot plate at least 5 minutes after the unit was on.
