Specimen Mounting Press (Mechanical Type)
The machine is used for mounting Metallographic Specimens in a suitable
thermoplastic or thermosetting material. Mounting makes the samples
convenient for handling in subsequent polishing operations.
Mounting of specimen is also essential where the edges of samples are to be
preserved or examinations. It is a screw press comprising of 1 dia.
mould of alloy steel, heat-treated and internally ground. Both the main
plunger and top plunger are also of heat-treated steel suitably hardened an
d ground. The ramming action is obtained by means of a ratchet lever
provided at the front. Drive is through a pair of hardened steel crown wheel
and pinion gears, The crown wheel is fitted on a heavy duty thrust ball
bearing. A screw type lock with handle is provided for quick fixing of top
plunger on mould during operation.
Specimen Mounting Press has concentric heating and cooling arrangement on
the mould, ensuring a quick turn-out of samples. The processing time per
sample is only 15minutes maximum. Heating is by means of 400 watts heater
and cooling by water circulation around the mould Standard Mould Diameter is
1 (1 ¼ diameter mould, optional). Extra mould assemblies
on any diameter, not exceeding 50mm. can also be supplied at an extra cost.
Provided with Energy Regulator, Pilot Lamp and Three Core Cable and Plug
Pin. Finished in high gloss enamel and chrome plating.
- Size: 12 x 12'' x 19 approx.
- Nett Weight: 38.5 kg. approx.
- Shipping Weight: 78kg. approx.
The specimen after mounting is to be polished on emery papers of different
grades. Usually papers of four grades are used in succession, from 1 to 000
grades. Occasionally 0000 grade is also required. These emery papers are
commonly avaiLable in 11 x 9 size and can be conveniently
fastened on Polishing Stand, after cutting into three lengthwise pieces.
rd Polishing Stand is designed to take four umbers of 11 x 3 9
(i.e. 1/3 sheet) emery papers of different grades. They are clamped on
polishing place surfaces by means of clamping arrangements on both ends of
the surface, thus holding them flat and tight. The entire mechanism is fixed
in a tray so that even wet polishing can be done on these polishing stands.
For wet polishing the stand is provided with water jets and drain. Finished
in high gloss enamel.
- Dimension: 16 x 16 x 5 approx.
Metallurgical Mounting Press
For permanent mounting of Metallographic of rock specimens in thermosetting
plastic, we offer Bakelite Mounting Press. The unit is of a rugged
construction and is activated by an hydraulic press, capacity 10 tonnes. The
unit is provided with a pressure gauge to read the pressure being applied
while mounting. The press is supplied complete with mould heater, cooler and
thermometer. As a standard outfit, 25mm. dia. mould assembly is supplied
along with the machine other sizes of mould assembly can be supplied as
additional accessories at an extra cost.
This provides a simple and positive method for ensuring that the metal
surface is exactly perpendicular to optical axis of the microscope. The
pressure on the plunger knob renders the upper polished surface parallel to
the under surface of the microscope slide on which it is mounted with a
plastic material such as plasticine. The Leveler is provided with a steel
shaft having bronze bushing, retracting spring and a structural steel frame
finished in hammer tone grey paint.
Metallurgical Specimen Cut-off Machine
This machine is required for quick and clean cutting off metallographic
specimens from rods and tubes etc. The abrasive wheel turns at a constant
speed driven by an electric motor suitable for operation from 230/230 volts
for 440 volts A.C. supply. The specimen is held securely in a vice type
holder and moved into the wheel. Specially placed and shaped coolant valve
are conveniently placed at the front of the machine. Hinged safety hood
lifts up for easy access for wheel replacement or tank cleaning.
