Finding the right polishing machine for metallography

When a new polishing machine has to be acquired for metallographic applications, the first thing to do is to consider the general sample throughput. For a small or medium sample throughput, manual grinding and polishing machines may be sufficient. For a regular workload with a high sample throughput, it is recommended to use a polishing device with automatic pre-grinding or polishing equipment. Polishing machines for metallography differ in their construction, size and ease of use. The size of the polishing device's support discs is an important parameter which has to always be taken into account. In case only samples of smaller sizes have to be processed, a device with Ø 200 mm support discs might be the right choice. In analogy, appropriate polishing machines for larger support discs exist for larger samples. The ease of use of the polishing equipment is just another factor that must not be underestimated. In this context, one should ensure easy handling and a secure and precise operation. All parameters relevant for the polishing process should be finely or infinitely adjustable with ease.

SCAN-DIA Polishing Machines for metallography

The company SCAN-DIA has a long tradition of manufacturing versatile high quality grinding and polishing machines for metallography. We have always attached great value to solid and easy to handle polishing and grinding machines for metallographic applications. The current range of products for metallography comprises polishing and grinding machines to suit different requirements. The size of support discs for both SCAN-DIA Grinding and Polishing Machine Series is variable. Polishing machines of the Series 33 can be equipped with Ø 200 support discs, while Series 37 allows the use of support discs with Ø 250 mm and Ø 300 mm. Some of the model variants of both series are equipped with the unique automatic floating chuck mechanism. Polishing machines of this design allow a very economical metallographic work even for a small sample throughput. All SCAN-DIA Polishing Machines for metallography come with a powder coated metal housing. Owing to their compact and space-saving design, these devices can also flexibly be used in smaller spaces.
