More than just a “grinding jack”

Quality and technology of a GREIF grinding machine ensure the unsurpassed long-term value.

Meet tomorrow’s UVV regulations today:

Forced-closing, two-part protective hoods with constant opening angle of 55°!

Consumption reduces the diameter of each grinding wheel. The protective hood and workpiece support must then be readjusted, because the support should always be close to the grinding wheel (§ 9 Para. 2 VBC 7 n6). In the case of one-piece protective hoods, this increases the opening angle and the risk to the worker from flying sparks and dust increases accordingly.

GREiF-Technik is not content with the connection of an extraction unit and the attachment of a protective glass. On the contrary, GREIF also offers a tailor-made solution here: the positively guided closing, two-part protective hood with a constant opening angle.

The upper and lower parts of the protective hood are connected by a hinge and each is additionally guided in its own groove in the protective hood holder. These grooves do not run parallel to each other, but converge towards each other, thus causing the upper and lower parts to close in a scissor-like manner. The extraction performance is not impaired by increasing extraneous air.

The further qualitative added values of the GREIF double grinding machines:

• ergonomically correct working height for all column machines
• Best cast iron stand
• Clamping flange formats according to DIN 6375
• Clamping flange material GGG 50, solid, for grinding wheel diameters of 300 mm and more
• Precision-ground clamping flange mount
• Lowest grinding wheel unbalance
• Shaft ends countersunk in the clamping flanges
• Grinding wheel sizes according to din 69120
• three-piece motor housing made of best iron casting for sizes from 300 mm upwards
• all turned parts CNC machined
• lockable main switches with undervoltage release for sizes from 300 mm according to DIN VDE 0113 part 1
• Backlash-free opposed, dust-tight and maintenance-free rolling bearings for low-noise operation and long service life
• Occupational safety tested by the employers’ liability insurance association
• functional and modern industrial design
• highly wear-resistant polyurethane 2-component coating
• Stator winding made of highly heat-resistant enameled copper wire type W180 to DIN 46416 Part 5 for tropicalized insulation class B to VDE 0530 Part 1
