Gesswein Abrasive Stones

Gesswein Abrasive Stones are designed to be used directly after machining or spark eroding in the preparation of surfaces for final polishing.
Among the stone types available are :-
MF Mouldmaker

(Grey/Blue), soft-bonded Silicon Carbide, which constantly presents fresh sharp edged particles to the work material. These stones produce fast stock removal and are widely used on hardened steel surfaces, as well as to rough finish non-ferrous materials. Excellent for contours. Generally used by hand.
MFP Mouldmaker Plus

(Grey/Blue), slightly harder than MF, the MFP cuts well with slower breakdown. It is a good choice for contours and radii, and generates a silky matt surface on hardened steels. Can be used on non-ferrous materials. May be used by hand or in a profiler.
EDM

(Orange) stones are designed to remove the tough hard scale left by ElectroDischarge Machining. These stones contain extra sharp particles of Aluminium Oxide, together with a small amount of Chromium Oxide, within a special bond, which enables them to follow contours. May be used by hand, or in a profiler.
EDM Blue

(Blue) stones are a natural development from the extremely popular EDM (orange) stones. Due to the inclusion of a small amount of cobalt, they are harder than EDM, maintaining their strength even in small section sizes, with good resistance to loading. Excellent for use in profiling or ultrasonic machines. EDM Blue stones break down slowly and cut fast. Very good for detailed work.
ROX Rough Out

(Dark grey) stones are large, relatively soft stones designed for maximum cutting with fairly fast breakdown. Used to remove rough machining marks or for "hogging" out material prior to the finishing process.
DF Diemaker

(Beige/light brown) This range of stones has established itself as one of the most popular in use today. Fast cutting with moderate breakdown, the DF can be used on both hard and soft steels, and is also suitable for some non-ferrous materials. Able to be used by hand or in profiling machines.
WP stones

Breakdown rapidly and are excellent at removing light scratches, or for use prior to polishing with diamond compound.
RA (brown) stones

Manufactured from very hard Aluminium Oxide within a resin bond to give flexibility and resilience. Excellent for corners, deep ribs and areas of fine detail, these stones produce a finer finish than other stones of the same grit. RA stones are extremely versatile and may be used by hand, or with profiler or ultrasonic.
OT Oil Treated (white)

These stones have been increasing in popularity over recent years. Able to be used on hard or soft mould and die steels, OT stones are made from white premium grade Aluminium Oxide, in a medium/hard bond, which is soaked in oil during the manufacturing process. This enables the stones to be used, if required, without lubrication. OT stones maintain good shape during use, and are excellent for processing machined or even EDM surfaces. Good for use in profiling machines.
US Ultra-Soft (White)

Specially developed for use on soft and nonferrous metals, with excellent results obtained on Aluminium in particular. Manufactured with an extra soft bond, the US stone shapes readily to contours. Fast cutting without loading. Recommended for use by hand only.
SF (Super Fine)

Made of levigated alumina, SF series has a very rapid breakdown and does not scratch. An excellent stone for P20 and P40 SS, use the SF for final finish prior to diamond polishing.
PW (Premium White)

Hard general purpose polishing stone, made of pure white premium Aluminium oxide abrasive, for use on all steels from hard to softer. Exposed sharp grains cause the stone to cut well. Good shape retention for finishing surface details. A special additive makes this stone load resistant. Both our PW and OT stones work well in a profiler and ultrasonic polisher.
CF (Classic)

The original Diemaker stone formulated in the puddled process preferred by traditional polishers. A puddled stone has more sharp cutting edges and acts more aggressive while resisting loading. Made of finely graded Aluminium oxide. Classic produces a uniform surface on all types of steel. Can be used in a profiler or ultrasonic polisher.
Gesswein Stones are available and priced in boxes of 12, with selected types also available within introductory Kits or in Pencil Stone Kits.
Xebec Ceramic Stones

Usage:
Perfect for Precise finishing of detailed surfaces, curves, ribs, bosses, etc., of various forming dies (especially plastic dies).
High finishing efficiency can be attained without clogging, even for metals such as aluminum, copper, gun metal, etc., which clogs with common finishers.
Use on narrow areas where other stones cannot be used because of breaking.
Use on complex shapes where uniform finishing could not be attained.
Meister Finisher finishes coarse surfaces after electro-discharge machining.
Features:
High finishing efficiency is realised by the crystal structure of the alumina fibres, which is optimum for finishing.
Finishing efficiency and strength have been improved by the two way liner structure, which prevents side slipping.
High accuracy of surfaces can be attained by the uniform fibre diameter.
No dropping of abrasive grain particles that can create linear scratches.
Little heat generation that minimises workpiece alteration and finisher deterioration.
Various finisher shapes can be used according to purpose.

Gesswein G-Flex Wheels

The Gesswein range of G-Flex Mounted Wheels are manufactured from the finest quality materials. These wheels can be dressed with a file to various shapes, their slight resilience keeps them from being too aggressive, they maintain their shape and do not clog, their nonloading and resilient characteristics enable abrading and finishing to be completed in one operation. Ideal in size and shape, their versatility enables them to be used in a variety of ways from polishing mould runners to forming and polishing the interiors of fine gold rings. Safety is an additional feature, the muslin laminates run parallel to the shank preventing the end from chipping.
Gesswein Belt Sticks

1/4", 1/2" & 3/4 An inexpensive hand tool to complement our range of other precision surface finishing products. Each plastic holder allows a narrow abrasive belt to be quickly fitted. As the abrasive wears, the belt can be easily inched round to expose fresh abrasive. The overall design of this tool makes it extremely useful for the dressing of irregular profiles. The holders are colour coded to promote correlation with the different abrasives thus:- Red (120 grit), green (240 grit), blue 320 grit), yellow (400 grit) and black (600 grit).
Kemet Stone Holders

Several types of Holders are available to suit many popular sizes of Gesswein (and other) abrasive stones, together with Xebec Ceramic Stones, Ruby Stones and lapping sticks.
The range includes Holders for use with reciprocating action machines. Some Holders have fixed axis shanks, some have variable axis shanks. For types are available for use by hand. Please Contact Us for details.
Kemet Stoning Oil
To ensure peak performance from your Gesswein Abrasive Stones, or indeed from most other types of abrasive stones, we have developed environmentally friendly Kemet Stoning Oil. Supplied in 2.5 litre or 5 litre containers. MSDS sheet available on request.
