Sample Preparation Surface Grinder

SPECTRAL 250 is a table-top portable surface grinder for the preparation of steel samples for spectroscopy. It’s compact design with vibration free operation makes it a practicle instrument to work with. Low noise and dust generation levels as well as standard outlet for dust exhauster are additional advantages.

250 mm grinding disc is dynamically balanced for smooth running. Grinding paper is sucked to the grinding disc which does not require any glue. Papers with 40-120 grit can be used to obtain the desired surface quality. The grinding disc is covered halfway by a lid, allowing grinding only in a segment.. A safety switch guarantees automatic switch off when the lid is opened.

spectral 250 surface grinder

SPECTRAL 350 is used to achieve excellent precision flat surfaces of iron and steel samples for spectroscopic analysis. The robust and vibration-free construction has been designed for continuous operation at high sample throughput.

SPECTRAL 350 Series of instruments are available as single disc and dual disc units with 350mm wheel size which is dynamically balanced for smooth running. Due to its special design, grinding paper is sucked to the grinding disc which does not require any glue.

spectral 350 dual surface grinder

SPECTRAL 350 Series are equipped with a strong aspiration device in addition to its special design, increasing vacuum for suction which retains the abrasive paper on the disc, eliminating the requirement for any adhesives or fixing attachments. Therefore, the abrasive papers can be used on their full widths and are very easy to exchange. The integrated dedusting system with spark trap allows a dust-free operation.

The grinding disc is covered halfway by a lid and the sheet metal allows grinding only in a segment for operator comfort and protection.

The machine is fitted with an interlocking safety device. When the lid is opened or the emergency button is depressed, the motors are stopped immediately.

Spectral 350-1 Single Disc Grinder with 2800 rpm fixed speed is the most basic unit of Spectral 350 series.

Spectral 350-2 Dual Disc Grinder has two discs with fixed speed of 2800 rpm.

Spectral 350-2S has two grinding discs with dual speed as 1400 and 2800 rpm. It's the most unique grinder, especially for foundries or steel plants having variety of materials.
