Spark Cutter, Micro Diamond Saw, and Micro Hotplate
Model TL-SC2 Spark Cutter
The TL-SC2 Spark Cutter has been designed for drilling holes, slots and discs of virtually any profile in hard metals.
The cutting speed will, of course, vary depending on the sample size and material. As an example, a hole can be drilled in a titanium sheet 0.3mm thick in about 3 minutes. The drilling tool can be made from any material, even copper, enabling special tools to be made with minimal effort.

Operation
Operation of the TL-SC2 is based on an electrochemical
process. The cutting tool [10) and the work piece are
connected to a power supply, the positive pole to the work
piece and the negative pole to the cutting tool, through
an electromagnet (7). By switching on the power supply,
an electric current flows through the circuit consisting of
the work piece, the electromagnet and the cutting tool.
When the magnetic field of the electromagnet lifts up the
cutting tool, the current is cut off and the cutting tool is
forced back to the work piece by the curved plate spring
(5), and then the cycle starts again.
The cutting is effected by the electrochemical process taking place at the moment the electrical circuit is broken. Considering the basic operating principle, it is obvious that the device can only be used for cutting highly conductive materials (with the exception of aluminum). The work piece holder (12) can hold 5mm wide metal bands. Different size work pieces can be accommodated with modification of the holder

TL-MS2
MicroSaw –
Diamond Saw
TL-MS2 includes: MicoSaw Diamond wheel, and Powder supply.
TL-MS1 MicroSaw
The MicroSaw is a small, versatile diamond wheel saw which is designed for cutting small pieces for TEM specimen preparation. It can be used under a standard stereo microscope which allows for precise positioning of specimens during cutting. The compact structure and ease of operation allows the user to reproducibly and rapidly prepare a section prior to thinning for TEM. Thin sections of ceramic materials, semi-conductors, and hard metals all can be sectioned with 0.01 micron accuracy.
Operation
The Model TL-MS1 is driven by an electric motor through a helical transmission. The 12 VDC is provided by the power supply subunit and the speed at which the wheel turns is adjustable in six different speed increments. Several different adjustments relative to the diamond cutting wheel can be made during operation. Adjustment of the specimen position and contact point of the arm can be accomplished. The tension of the arm can also be adjusted, as well as the downstop control for the arm. Two adjustment screws at the bottom of the instrument allow height adjustment of the stand, providing a method for leveling the MicroSaw underneath the stereo optical microscope.

MicroHeat –
Model
TL-MH2
The MicroHeat is a small, compact hot plate which offers an easy method for mounting 3mm TEM specimens prior to grinding and polishing or ion beam milling.
Input power is 6 VAC, 14 watts, temperature range 50 – 200ºC
Operation
The Model TL-MH1 is a relatively simple instrument to operate. It uses a control circuit which amplifies the signal of the thermocouple underneath the heated table. The circuit compares it to the temperature preset on the control panel, and if the temperature of the table is smaller than the required value, the control circuit switches on the heating element. Once the heated table reaches the required temperature the control circuit switches off the heating element. The control circuit maintains the temperature of the heated table to within +/- 2 degrees Celsius. The temperature of the heated table usually reaches the set temperature within 2-5 minutes of operation. However, it is recommended to operate the plate at least 5 minutes after switching the instrument on.
