Tool set
HERMAN QGX-14
For straight grinder

Grinding wheel on a shank HERMAN FWS-10/S:

Large core made of special synthetic resin:
reliably holds the lamellae and safely withstands high peripheral speeds

Primary raw material - abrasive belts (KLINGSPOR material) with a layer of abrasive grains made of industrially produced corundum:
long service life and very good removal when processing ferrous and non-ferrous metals of medium hardness

Abrasive carrier medium - cotton cloth:
for elasticity, flexibility and good ability to follow the shape of the surface to be processed

Optimal lamella density for efficient machining:
the selected number is the result of long-term testing and depends mainly on the diameter and grit of the tool

Grain size standard in the range P60 to 120 according to FEPA (approx. 120 to 270 µm):
allows selection of the appropriate tool from rough grinding to fine finishing work

Warning:
when working, do not exceed the maximum speed indicated on the product.

Grinding cuffs HERMAN GSB-10/S:

Primary raw material - grinding belts with a layer of abrasive grains made of aluminum oxide (industrially produced corundum):
long service life and very good removal when processing ferrous and non-ferrous metals, hard and soft wood and plastics

Abrasive media carrier - combined fabric made of cotton fiber and synthetic polyester fiber (poly-cotton):
high strength and increased tear resistance, optimized to handle extreme centrifugal forces arising from tool operation at high peripheral speeds

Smooth running of the grinding cuff and work with minimal vibration:
the condition is the use of a suitable carrier that ensures the fastening of the sleeve against slipping.

Grain size standard in the range P40 to 80 according to FEPA (approx. 500 to 250 µm):
allows selection of the appropriate tool from aggressive to coarse grinding

Carrier for grinding cuffs HERMAN RH-80/S Medium:

Flexible, medium-soft design (hardness 55-65):
when grinding in combination with appropriate pressure, it partially adapts to the uneven surface of the workpieces

Made of synthetic rubber:
good mechanical strength, resistant to abrasion and aging, as well as to oils and other similar chemicals

Stable properties over a wide temperature range:
a slight change in properties occurs at ambient temperatures below -20°C and during prolonged grinding and overheating of the pad to a temperature of more than 120°C

Warning:
do not exceed the maximum speed when working (30,000 rpm for Ø 10mm, 16,000 rpm for Ø 25mm, 8,500 for Ø 45mm)

Cleaning wheel on a shank HERMAN FWK-10/S Dragon Black:

Primary raw material STRIP-IT Black high quality (3M material):
support spatial mesh structure made of durable nylon fibers, impregnated with synthetic resin containing silicon carbide abrasive

Stability of the structure of the primary raw material:
the structure of the tool does not change under the influence of grinding, thus allowing repeated use with unreduced power

Elasticity as a key feature:
enables cleaning even highly uneven surfaces

Reduced sparking intensity during machining:
mainly due to silicon carbide grains in the synthetic resin

The contact surface is only minimally contaminated with dirt:
the grinding dust from the pores is easily released during grinding due to centrifugal force

The porous structure dissipates heat effectively:
ambient swirling air easily penetrates the pores and contributes significantly to cooling the tool

13mm thick, small diameter abrasive body:
combined with the elasticity of the primary raw material, it allows cleaning even in the most inaccessible places

Gentle on the workpiece:
silicon carbide with a suitably selected grain size does not cause damage to the surface and maintains its shape

Cleaning wheel on a shank HERMAN FWK-20/S Dragon Green:

Primary raw material STRIP-IT Green high quality (3M material):
spatial mesh support structure made of durable nylon fibers, impregnated with synthetic resin containing corundum-based abrasive

Stability of the structure of the primary raw material:
the structure of the tool does not change under the influence of grinding, thus allowing repeated use with undiminished performance

Elasticity as a key feature:
enables cleaning even highly uneven surfaces

The contact surface is only minimally contaminated with dirt:
the grinding dust from the pores is easily released during grinding due to centrifugal force

The porous structure dissipates heat effectively:
ambient swirling air easily penetrates the pores and contributes significantly to cooling the tool

13mm thick, small diameter abrasive body:
combined with the elasticity of the primary raw material, it allows cleaning even in the most inaccessible places

Aggressive cleaning and removal:
coarse-grained aluminum oxide intensively removes dirt and penetrates the surface of the material
