Single Disc 203mm Manual Metallographic Polishing Machine 50rpm-600rpm

Single Disc 203mm Manual Metallographic Polishing Machine with Stepless Speed 50-600rpm

Brief Introduction: 

iqualitrol Single Disc Mopao-160E grinder polisher is suitable for pre-grinding, grinding and polishing metallographic specimens. Since the machine is speed-adjusted by microprocessor, it can run at speed of 50 to 600rpm,which favors the machine with wide applications.

Mopao-160E is equipped with cooling system that can cool down the specimen during pre grinding so as to prevent overheating and damage the metallographic structure.

Featuring easy operation and reliable performance, it is an indispensable device for the factories, research institutions and college labs to prepare metallographic specimen.

Technical Specifications:

After mounting, the specimen is wet ground to reveal the surface of the metal. The specimen is successively ground with finer and finer abrasive media. Silicon carbide abrasive paper was the first method of grinding and is still used today.

Many metallographers, however, prefer to use a diamond grit suspension which is dosed onto a reusable fabric pad throughout the polishing process. Diamond grit in suspension might start at 9 micrometres and finish at one micrometre.

Generally, polishing with diamond suspension gives finer results than using silicon carbide papers (SiC papers), especially with revealing porosity, which silicon carbide paper sometimes "smear" over.

After grinding the specimen, polishing is performed. Typically, a specimen is polished with a slurry of alumina, silica, or diamond on a napless cloth to produce a scratch-free mirror finish, free from smear, drag, or pull-outs and with minimal deformation remaining from the preparation process.

After polishing, certain microstructural constituents can be seen with the microscope, e.g., inclusions and nitrides.

If the crystal structure is non-cubic (e.g., a metal with a hexagonal-closed packed crystal structure, such as Ti or Zr) the microstructure can be revealed without etching using crossed polarized light (light microscopy).

Otherwise, the microstructural constituents of the specimen are revealed by using a suitable chemical or electrolytic etchant.

The metallographic grinding and polishing machine Mopao-160E made by iqualitrol has passed CE certification. It features a sturdy and durable base, equipped with high-precision spindle and transmission mechanism, which effectively absorbs vibration during grinding and greatly increases comfort in use.

Mopao-160E can obtain smoother grinding samples and reduce laboratory noise. The machine can be equipped with a fast magnetic adapter, compatible with various diamond grinding systems, facilitating quick switching of various grinding consumables and greatly expanding the scope of equipment applications.

The stainless steel ceramic faucet customized by a Taiwanese sanitary ware manufacturer is used to meet the special needs of metallographic grinding, including water flow rate and angle, while also being aesthetically pleasing and practical.

The drainage system adopts an anti-clogging triangular waterway design to solve the problem of clogging caused by grinding consumables for long-term users. We use the shortest waterway distance and angle design to reduce the probability of clogging.

The waterproof film panel has 9 sets of grinding and polishing parameter memory functions. Different grinding speeds, directions, and times can be set for different materials and requirements, which can be changed at any time to meet different grinding and polishing needs.

When used for automatic polishing, an automatic dripping device can be purchased to allow polishing consumables (diamond suspensions, alumina powder, final polishing liquid) to automatically drip onto the polishing disc according to the set time.
