Sample Preparation for Spectroscopy - SPECTRAL Series
Sample Preparation for Spectroscopy - SPECTRAL 250
SPECTRAL 250 is a Table-top Surface Grinder for spectroscopic sample preparation of steels and irons. It’s a compact design with vibration-free construction makes it a practical instrument to work with. It has robust steel housing, strong 1,1 kW motor, working disc of 250 mm dia., a rapid stop of the turning disc, suction created by special design retaining the abrasive paper on the disk (no need to glue or fix), disc covered halfway by lid allowing grinding only on a segment, spark trap, dust box and standard outlet for exhauster, easy to clean and ready for operation. 110/230 V, 1-phase, 50 Hz.
Sample Preparation for Spectroscopy - SPECTRAL 350
SPECTRAL 350 Dual Disc Grinder 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 has two independently driven grinding discs of 350 mm which are dynamically balanced for smooth running and the speed of each disc can be set either to 1400 RPM or 2800 RPM. Coarse and fine grinding on two separate grinding discs can be done on the same machine. Due to its special design, grinding paper is sucked to the grinding disc which does not require any glue. SPECTRAL 350 can be 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. Strong Aspiration Device (Blower) unit available as an accessory with easily replaceable filter creates a dust-free working environment. Both discs are covered halfway by a lid and the sheet metal only allows grinding per segment for the operator’s comfort and protection. Magnetic and mechanical specimen holders are available to ensure maximum operator safety. SPECTRAL 350 is further equipped with breaking device permitting a rapid stopping of the turning discs. The machine is fitted with an interlocking safety device the permits the lid from being opened before the motors are stopped.
Sample Preparation for Spectroscopy - SPECTRAL PG
SPECTRAL PG is a compact bench-top pendulum grinder for fast grinding of iron and steel samples for spectroscopic analysis. It has a simple and reliable design with low noise and dust generation levels. It is completely enclosed and dust-proof with LED spot light. The front cover can be completely opened for easy access to all sides.
SPECTRAL PG is suitable for wet and dry grinding with minimum maintenance required which is mainly cleaning. It is possible to attach an external dust exhauster to the standard outlet at the rear side. The grinding arm is placed just in front of the machine making it ergonomic and easy to handle. SPECTRAL PG is especially suitable to grind hard materials like white cast irons. It is also possible to prepare other materials by using special stone cup wheels which are easy to exchange. Vertical movement (Z axis) of grinding head is by hand wheel in front and positioning with 0,01 mm accuracy is possible. Reproducible flat surfaces are achieved with column mounted on taper bearings. Manual V shaped clamping vice, Electromagnetic and Mechano-magnetic plates are available as accessories. Spectral PG is equipped with braking device permitting a rapid stop of the grinding wheel. The machine is fitted with an interlocking safety device not allowing the hood being opened before the grinding motor is stopped
Sample Preparation for Spectroscopy - SPECTRAL MM
An automatic milling machine for fast milling of non-ferrous and steel samples for emission and X-ray spectrometer analysis. Automatic fine surface milling guarantees the highest level of reproducibility through automatic processing of the specimen. SPECTRAL MM has a robust and reliable design with low noise and emission levels. It is completely enclosed and sound-insulated with LED spot-light. The front cover can be completely opened for easy access to all sides. The unit is equipped with automatic sample feed with fine speed control. Fast advance and reverse are available. All important parameters of the milling process like feed rate, milling depth, spindle speed are adjustable on the touch screen LCD. The spindle speed can be adjusted to different materials to achieve optimum surfaces. Reproducible flat surfaces are obtained with column mounted on taper bearings. SPECTRAL MM is suitable for different sample shapes (cylindrical, mushroom shaped etc.) with diameters up to 80 mm. It can be fitted with special cutter head with 8” diamond or tungsten carbide tips. Three-point-chuck is included in the standard scope of supply of the machine. Other additional clamping devices are available as optional accessories.
SPECTRAL MM is equipped with highest level of the safety standards. Several safety circuits guarantee optimum protection for the operator. An electronic brake system is integrated to the system for a rapid stop of the milling head. The interlocking safety device does not allow the hood to be opened before the milling motor is stopped.
A smart clamping solution tor practicaldaily use:pneumatic clamping device offers advantages in milling and general use. The pneumatic clamping device can be used for accurate clamping and increase productivity and ensure repeatable alignment. Air cooling system is also offered optionally Which is ideal for applications especially for steels and hard material.
SPECTRAL MM has advanced techniques and software with programmable HMI touch screen controls increasing the productivity, sample consistency and operator comfort
Controlled Material Removal:
SPECTRAL MM allows you to preset the amount of material to be removed very accurately. The vertical movement of the milling head is motorized with digital positioning and display on the touch screen LCD. The robust design of the column guarantees high reproducibility. The material to be removed from the specimen can be preset in increments of 10 microns
The preselection of the milling feed rate (0.,1-5mm/sec) is possible from the touch screen LCD. The feed rate is automatically adjusted, if needed reduced, resulting in perfect surfaces and eliminating sample and machine damage.
SPECTRAL MM can be programmed to make multi-pass milling operations. It is possible to set the number of passes and the milling depth of each pass which can be stored under a program number or name.
Programmable Return Positions: (SPECTRAL MM has 3 different stop modes)
Auto stop: Stops when the specimen has been through.
Relative Stop: Stops when it has returned to its starting point.
Absolute Stop: Stops when the ultimate reset point in all axes has been reached.
A library of 25 different milling programs with related specimen name or number can be saved with all milling parameters which can be recalled at anytime. Data with Qualitest milling tips is also listed for easy selection.
