Model
910 - Lapping and Polishing Machine
This model 910 is specially designed to provide all of the features required to obtain outstanding results using the EMS Polisher. The Polisher is designed for SEM cross sectioning and also for TEM wedge polishing preparation. For instance, TEM wedge polishing requires that the polishing wheel rotates at a constant speed with high torque at a very low rpm.
This combination of features is not found in standard grinders. Our model 910 provides all of the requirements that a Tripod Polisher needs. This includes the use of diamond lapping films and either colloidal silica or colloidal alumina suspensions. Plain backed diamond lapping film adhered to a glass plate by surface tension, and is easily removed for storage and re-use. Model 910 is also designed for ease of cleaning and disposal of abrasive debris.
Features
- Variable speed from 8 - 600 RPM
- Solid, cast aluminum construction
- Low speed, high torque rotation (makes it ideal for Tripod Polishing)
- Vibration free, quiet operation
- Stylish, tabletop design

Model
920 - 8” Lapping Machine
The model 920 is the first in a new generation of multi-purpose lapping machines designed for accurately lapping and polishing a wide range of materials. The 920 can be used as a standard metallurgical grinder/polisher utilizing abrasive papers, abrasive films, diamond discs, polishing cloths, etc., or it can be used as a high precision free abrasive lapping machine for flat polishing of optical and semiconductor materials.
When used as a free abrasive lapping machine, the 920 can accommodate most of our Lapping Fixtures for precise sample orientation and maximum flatness. The precision fixtures and the self turning lap ensure samples of the highest quality. In addition to flat lapping, we offer 2 fixtures for polishing oriented crystals. The crystals can be oriented and subsequently polished while maintaining their orientation.
The Model 920 is also available with two optional workstations. These independently controlled workstations rotate polishing fixtures automatically, thereby simplifying the polishing process and minimizing operator supervision. The 920 is ideal for high precision polishing in both R & D and production environments.
FEATURES:
- Variable Speed, 10 - 600 RPM
- Solid, Cast Aluminum Construction
- Quick exchange of worn-out disc
- Optional workstations for semi-automatic polishing
- Stylish, Tabletop design
- Vibration free, quiet operation

Lapping
and Polishing Fixtures
The Electron Microscopy Sciences Precision Lapping and Polishing Fixtures are designed to accurately produce polished parallel, tapered or critically oriented samples with minimal sub-surface damage. A series of specialized fixtures has been developed for lapping and polishing samples up to 6" in diameter, TEM samples and oriented crystals. In addition to size and shape, the fixtures differ in the type of thickness control techniques they employ. The Lapping and Polishing Fixtures are designed to be used either by hand or with a lapping machine (Model 920 above). Sample Mounting Fixtures are also designed to be used in conjunction with these fixtures to ensure that the sample is mounted parallel to the mounting block and that a thin, uniform layer of wax exists between the mounting block and the sample.
Micrometer Controlled Fixtures
The micrometer method of thickness control employs a dial with 25 micron or finer graduations, that is adjusted relative to the outside support ring to set the amount of material to be removed. To set the dial, the sample is initially zeroed against the lapping plate and then the dial is adjusted to create a gap between the outside support ring and the center slide. This gap corresponds to the amount of material to be removed and gradually decreases, as the sample is lapped or polished, until the final thickness is reached. The load on the sample is varied by adding weights or finger pressure to the top of the fixture. Due to the ease of adjustment, a micrometer controlled fixture is generally used when desired sample thickness will vary from sample to sample.
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.
Model
145 Lapping and Polishing Fixture
This model accommodates up to a½" sample mount, which is held in place using a threaded draw rod and locating pin. This small, lightweight fixture is ideal for hand lapping or polishing of samples less than ½" in diameter.
Model 147
The Model 147E is designed for edge polishing applications where rods, wafers, or fiber optic components are mounted vertically and polished edge on.
Model
150 Lapping and Polishing Fixture
This model accommodates sample mounts up to 1" in diameter for both parallel and tapered samples. Angled blocks up to 45 degrees are available and are simply mounted in place of standard parallel mounts when tapered sections are desired. The mounting blocks from this fixture are directly transferable from any cutting saw. The Model 150 is for general-purpose fixture and is capable of lapping and polishing multiple small or large samples up to 1" in diameter.
Model
151 Counter-Balanced Lapping and Polishing Fixture
This model is identical to the model 150 except that the center slide is completely counter-balanced which enables the user to precisely vary the sample load. The model 151 is ideal when lapping or polishing very delicate materials, where only a minimal sample load can be tolerated.
Model
155 Lapping and Polishing Fixtures
This model works the same as the Model 150, but accommodates sample mounts up to 2" in diameter. A streamlined design reduces the overall fixture weight, which makes it ideal for lapping either by hand or on a lapping machine. This model also has replaceable tungsten carbide feet.
The Model 155V has the ability to mount specimen up to 2" diameter using vacuum. The Model 155D has a digital indicator allowing 1micron resolution during the lapping and polishing process.
The Model 155DV combines both the Model 155D and the Model 15501 Vacuum Kit Accessory. It uses a digital indicator with vacuum mounting to provide the most precise and accurate lapping and polishing capability. Specimens up to 2" diameter can be mounted with vacuum and monitored with 1 micron resolution during processing. An additional vacuum plate must be purchased separately for use with the vacuum option.
Model 155L
The Model 155L (Previously Model 154) is ideal when lapping or polishing very delicate materials, where only a minimal sample load can be tolerated. The 155L uses counter-balance springs to reduce specimen load. The fixture is capable of lapping and polishing multiple small samples or larger samples up to 2" in diameter.
Model 155E
