MiniMet 1000 Grinder Polisher

The MiniMet 1000 Grinder-Polisher is a sample preparation system that quickly prepares materials for

cross-sectional analysis. Its space saving design employs a patented geometric action that combines the

advantages of hand-lapping as well as mechanical polishing. This motion provides a random polishing

action, eliminating any induced polishing artifacts.

The MiniMet 1000 adjustable speed and high pressure capability reduces preparation time and makes it

easy to prepare advanced ceramics, composites, and even large hardened steel sections.

Safety Information

For safe installation and operation of this equipment, carefully read and understand the contents of this

manual. Improper operation, handling, or maintenance can result in equipment damage and personal

injury.

The MiniMet 1000 is designed for use in dry, indoor laboratory and workshop environments away from

strong electromagnetic fields and with normal temperature ranges (41° F to 104° F / 5° C to 40° C) and

non-condensing humidity ranges (30-90%).

Machine Use and Care

All operators should be trained in the use of grinder polishers.If training is needed contact

Buehler at 800.BUEHLER (800.283.4537) or your local Buehler Sales Representative.

Always use safety glasses. Flying debris and liquids can cause severe eye injury.

Dress properly. Do not wear loose clothing or jewelry and contain long hair. They can be caught

in moving parts and can result in severe personal injury. Protective equipment should be worn to

handle specimens, which may be sharp or hot.

Do not operate machine in explosive atmospheres, such as in the presence of flammable

liquids, gases, or dust. Sparks may ignite the dust or fumes.

Maintain the MiniMet 1000 with care. Properly maintained machines are less likely to bind and

are easier to control. Any alteration or modification is a misuse and may result in a dangerous

situation.

Only qualified repair personnel must perform machine service. Service or maintenance

performed by unqualified personnel could result in a risk of injury.

Replace damaged or defective parts immediately and use only identical replacement parts.

Use of unauthorized parts or failure to follow maintenance instructions may create a risk of

electrical shock or injury.

Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the machine operation. If damaged, have the machine serviced

before using. Poorly maintained machines cause many accidents.

Do not abuse the power cord. Never use the cord to cart the machine or pull the plug from

an outlet. Keep the cord away from heat, oil, sharp edges, or moving parts. Replace

damage cords immediately. Damaged cords increase the risk of electrical shock.

Use of extension cords is not recommended for Buehler machines and equipment.

Installation of the MiniMet 1000 must comply with local electrical standards or codes of practice.

The Specification Plate is located on the back of the MiniMet 1000. Check that the Specification

Plate values for voltage, current, and power consumption are compatible with the intended

electrical supply before installation.

The MiniMet 1000 can be plugged into an outlet rated for the voltage and frequency listed on the

Specification Plate.

Activating the MiniMet 1000

To activate power to the MiniMet 1000, move the power switch on the back of the machine to the

ON position.

The power switch is also a circuit breaker that will provide protection for the machine in the event

of an overload.

If at any time the control panel buttons or motor does not operate, reset the MiniMet 1000 by

moving the power switch to the OFF position then back to the ON position.

MA691100_14.1 [Original Instructions] 4/08/2013

MA691100_14.1 [Original Instructions] 4/08/2013

SELECT...........Press the SELECT button to scroll through and select a parameter:

TIME, SPEED, FORCE, and SOFT STOP.

TIME ...............Press the INCREASE or DECREASE buttons to set a TIME

value from 30 seconds to 9 minutes, in 10 second increments.

TIME can also be set for continuous operation. ON will be

displayed in the LCD indicating continuous operation.

SPEED.............Press the INCREASE or DECREASE buttons to select a speed

from 10 to 50 rpms, in 5 rpm increments.

FORCE.............Press the INCREASE or DECREASE buttons to select a force
