DESCRIPTION

Design

MICRACUT 152 precision cutters are used for precise and

deformation-free cutting of “Metals, Ceramics, Electronic

Components, Crystals, Composites, Biomaterials, Sintered

Carbides, Minerals, etc.” MICRACUT 152 has its place in

virtually any metallurgical, geological, electronics, research,

biomedical or industrial laboratory. The applications are

endless.

•Modern and sturdy design

•Easy to use control panel with ergonomic turn-knob

•Precise micrometer with digital readout

•Gravity feed system

•Automatic stop at the end of cut

•Transparent protection hood with magnetic safety

switch

•Inbuilt recirculation coolant tank

MICRACUT 152 accommodates diamond and abrasive wheels

up to 175 mm (7”) diameter and the speed range is between

50 and 1500 rpm. Modern-looking touch pad controls with

ergonomic turn knob allows fast and easy setting of wheel

speed and increases productivity. The gravity feed loading

design minimizes sample deformation. The sliding weight arm

with counterweight allows precise force application. The

digital micrometer enables the operator to set the cutting

width with a resolution of 1 micron. The digital micrometer is

interchangeable and the customer can mount other types of

micrometers if and whenever required. The coolant tray is

removable from the instrument for easy cleaning. MICRACUT

152’ s cutting chamber is fully enclosed by a transparent

hood. Blade dresser is optionally available. At the end of the

cut, the motor automatically stops and an audible signal

notifies the operator.

Optional Cutting Table Attachment is available for manual

cutting of extra flat large specimens and PCB’s.

MICRACUT 152 precision cutters are capable of cutting most

materials such as, brittle or ductile metals, hard or soft

metals, composites, ceramics, rocks, biomaterials, laminates,

etc. They are designed for cutting all types of materials with

minimal structural deformation.

The structural integrity of the sample is maintained through

MICRACUT 152's design and operation. Additionally, low kerf-

loss and sample holding versatility makes the MICRACUT 152

an essential part of the modern day laboratory. The cut

surface is ready for microscopic examination with minimal

polishing.

Safety

MICRACUT 152 precision cutters has the highest safety

standards. The magnetic safety switch does not allow the

motor to be started unless transparent hood is closed. If

transparent hood is opened during cutting, the motor

immediately stops automatically. Easily accessed and

operated emergency stop button ensures immediate shut

down. Soft closing feature of transparent hood protects

fingers from risk of injury.

Installation and Set-Up

CAUTION

Follow approved procedures and take all

necessary preventive safety measures when

lifting and installing this equipment. Improper

lifting can result equipment damage.

The MICRACUT 152 is shipped completely assembled except

its digital micrometer for safely shipment. It is designed for

table-top placement. After unpacking select a smooth

location to place the MICRACUT 152. Then, adjust the leveling

feet to make the equipment parallel (set-square). Locate the

MICRACUT 152 with convenient access to a grounded type

electrical receptacle.

Electrical Installation

Before making electrical connections, check that the voltage

and frequency stated on the specification plate correspond to

the local voltage and frequency. Check that the values for

one-phase grounded voltage, is compatible with the intended

electrical supply before installation.

Connect the mains cable of the MICRACUT 152 to an

appropriate electrical outlet.

Close the door. Turn the instrument on from the main

switch, which is on the backside of the instrument.

See Cutting Operation section for operation.

Press “START” and “STOP” buttons and observe from the

window that the cutting wheel shaft rotates clockwise

when looked at from the left.

ATTENTION

Connect the unit to the grounded mains

voltage. The MICRACUT 152 requires a 1-phase

electrical supply.

WARNING

Electrical Shock Hazard. A qualified electrical

technician should perform all hard wiring and

electrical maintenance

Disconnect the power supply before making any

electrical adjustments.

Make sure that the supply voltage and frequency is

correct. Check the values from the machine identification

plate located at the rear of the machine

You can see suitable power sockets as below. If you have

not suitable power socket, in this case you should supply

a suitable power cord.

Cooling Unit

The MICRACUT 152 uses the “drag” principle of lubrication

with the lubricant carried to the sample on the periphery of

the wheel. METCOOL Cutting Fluid reduces cutting time and

produces superior quality cuts. Its use promotes effective

lubrication which allows the diamond particles to cut cleanly.

Coolant is lost during the cutting process because of

evaporation or left in the cutting chamber or components. For

the best cutting performance and corrosion protection,

replace the coolant regularly (max. 1 month)

IMPORTANT

ONLY water-based cooling fluids has to be

used. Use of alcohol or oil based flammable

cooling fluids are strictly FORBIDDEN because;

the vapor is potentially EXPLOSIVE when

ignited.

CAUTION

Do not run the pump dry for more than 30

seconds.

For removing the water tank, please follow the below steps:

Remove the cutting-wheel.

Open the covers which are under the wheel
