Pendulum Grinder for Sample Preparation

Spectral PG 52 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.

SPECTRAL PG 52 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 52 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 handwheel 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 AG 102 is an automatic cup grinder for spectroscopic sample preparation of iron and steel samples.

Heavy duty cast aluminium base with motorized vertical drive provides accurate control. High-torque grinding motor rotating at 2800 rpm guarantees high material removal rate. Spectral AG 102 is equipped with automatic sample feed with fine speed control. Fast advance and reverse are available. Automatic cup wheel positioning is done with a laser measurement station. This ensures extremely precise positioning with shorter times. All important parameters of the grinding process like feed rate and grinding depth are preset with digital display. Pneumatic Clamping Device, Electromagnetic clamping device and T-slotted table are offered as optional accessories.

An automatic diamond dresser keeps the grinding stone plane and sharp for optimum performance and precise results. The multi-pass grinding depth is monitored accurately with material height measurement system. Instead of relying on preparation time, the necessary amount of material to be removed can be specified with the shortest possible grinding time.

Fully Automatic Operation

• 7” coloured HMI touch screen and user-friendly software allows easy view and control of all steps. Up to 99 different cutting programs can be saved.
• An automatic diamond dresser keeps the grinding stone plane and sharp for optimum performance and precise results.
• Controlled Material Removal allows you to preset the amount of material to be removed very accurately. Instead of relying on preparation time, the necessary amount of material to be removed can be specified with the shortest possible grinding time.
• Multi-pass grinding: It is possible to set the number of passes and the milling depth of each pass.
