Grinder, Otolith Polishing, and Micro Polisher

Micro-Mill® Grinder

For fast, high-speed grinding of small samples from 20 to 50mm (¾" to 2"). The unit comes with a stainless steel or hard-faced blade which rotates at speeds up to 12,000 rpm and will successfully grind bauxite, bone, ceramics, coal, Devorda's alloy, fertilizer, filter paper, fly ash, frozen tissue, glass, grain, kaolinites, leaves, limestone, muscle tissue, pharmaceuticals, pigment blends, plastics, rocks, roots, seeds, slags, soil, teeth, wood, etc. The grinding chamber measures 2 1/8"dia.x 1"deep (54x25mm). Its overall dimensions are 5½" x 7" x 11"(H) (14x18x28cm). It comes with a 6 FT. (1.8m) 3-wire cord and grounded plug. Power: 115V, 60Hz or 220V, 60Hz.

Features:

• The grinder operates only when the cover is latched and in place. This provides safety and prevents sample loss.
• The temperature of the grinding chamber can be maintained by means of built-in heat exchangers. ¼" (6.4mm) tubing connections on the cover and housing accept tubes for circulating water, methanol/dry ice liquid, or liquid nitrogen.
• The cover, grinding assembly, and milling blade head are removable for easy cleaning.
• The aluminum housing has an epoxy finish and non-skid rubber feet.
• The control panel has an overload protection reset button and a pilot light.
• The 1/5 horsepower (150 watts) motor develops a torque of 30-ounce-inches (2.2 Kg-cm) at 12,000 rpm.

MultiLapTM Fish Otolith Polishing Tool - Model 195

In many materials preparation laboratories the need for high specimen throughput and precision made specimen preparation tools is a difficult bottleneck to correct. The Model 195 MultiLapTM is designed to grind and polish multiple specimens with precise control over each individual specimen. The fixture incorporates up to 6 separate pistons which are used for holding the specimen during preparation and controlling the amount of material to be removed. The piston assemblies allow for specimens of up to 1” diameter to be polished in 10-micron increments. The specimen mounts also provide a means for viewing the specimen in transmitted light, enhancing detection of features that require a light transparent specimen.Wear resistant Delrin plastic legs provide support and are very gentle on many types of abrasive films and media. Overall, the Model 195 is a versatile and precise instrument for performing any precision lapping processes and is an excellent addition to any specimen preparation lab.

Features

• Tungsten carbide base resists wear and maintains sample planarity.
• Wide base ensures stability thereby minimizing sample damage and edge rounding.
• Wear ring is replaceable, on some fixtures, which extends the life of the fixture.
• Can be mounted in the Model 920 Lapping & Polishing Machine for semi-automatic processing.
• Micrometer depth control allows precise control over sample thickness.
• Precisely crafted stainless steel construction ensures long life and high precision.

MicroPol™ Polisher For TEM & Metallography - Model TL-MC1

The MicroPol™ Polisher is a small, versatile mechanical fine grinder and polisher, which combine the advantages of both manual and automatic polishing. The parameters of polishing (speed, load, time, etc.) can be matched according to the properties of the specimen. High quality samples can be prepared with minimal effort by the operator.

Application:

While the MicroPol™ TL-MC1 is well suited for metallographic polishing; it has been specially designed for precision TEM polishing applications. Two specially designed TEM sample holders are included with each unit, which makes it ideal for the preparation of both plane view and cross sectional HREM samples. A 1”diameter stainless steel mounting block is also supplied, which simplifies processing of sample for applications including optics, mineralogy, quality control and failure analysis.

Operation:

The arm of the MicroPol™ moves the specimen holder or the specimen itself in a random geometric pattern gently pressing it to the bottom of a bowl containing suitable abrasive material. The abrasive material can be grinding paper, abrasive films or loose abrasive on either a polishing cloth or copper plate.

Features

• Rugged, corrosion proof construction
• Variable speed control for precision polishing
• Quick change bayonet mount bowls
• Utilizes economically sized 3” diameter PSA cloths
• Large 35mm maximum sample size
• Timer for automatic operation
• 2 precision TEM sample holders included
• Extremely light load for fragile TEM Samples
