First-class raw materials for exceptional products.

Many TYPEs of diamond exist. Selection of the suitable raw materials, their professional treatment and a precise and clean classification of the micro grain sizes are all extremely important for the quality of the end product, i.e. the lapping and polishing agent. Differentiation is made between the following TYPEs of diamond:

Natural diamonds
predominantly possess angular, extremely high-strength particles with numerous short but sharp cutting edges. Their regular grain shape and crystal structure enables a high rate of material removal, in particular with hard metals and ceramics, and delivers very good surface values on the workpiece.

Diamonds from normal synthesis
are characterised by their angular to splintered particles. Their grain shape and crystal structure results in a high rate of material removal in particular with hardened steel. Fracturing results in cutting edges that are partially self-sharpening.

Diamonds from explosive synthesis
With their rounded, brittle polycrystals they deliver very good polishing results, in particular in the grain size range of 3µm and finer. Thanks to their grain shape they are particularly well suited for use in the polishing suspensions employed in lapping machines.

Diamond pastes

When manufacturing all of our diamond products we only use healthy original material. This means: We do not use diamonds that have been recovered from grinding tools.

The micro grain sizes conform to grain size D46 - the smallest grain size extracted through screening. These are obtained through sedimentation and are measured in accordance with the FEPA STANDARD. However, we use grain size distribution curves that are stricter than the conventional curves due to our high quality standards, so that our classification is considerably more precise than that of other products. With good reason:

Each grain size has an upper and lower limit value. Within these limits at least 90% weight should comply with the specified grain size, whilst the remaining 10% of the mass portion is defined as half oversized and half undersized respectively. The oversized outliers in particular can significantly reduce the quality of the overall product: Because this TYPE of rough grain can act as a spacer between the workpiece and polishing agent. This dramatically reduces the removal rate of the grain size and the surface may be damaged by deep individual scratches.

In order to guarantee compliance with the required tolerances for first-class micro grain sizes, extensive monitoring is required. We use a laser diffused light spectrometer for this purpose, as well as a powerful microscope system in conjunction with computer-aided image analysis. We are happy to put in this effort: In order to assist you in obtaining the best results possible.

The high quality of our products allows us not only to guarantee you consistently reproducible results, but also efficient processing times for your workpieces.

liqui-plus diamond sprays

The diamond particles are integrated in a suspension for improved sliding characteristics. This is simply sprayed onto the workpiece as thin film. In order to obtain optimum results, we offer you two different TYPEs of liqui-plus diamond spray in 200ml spray bottles:

Diamond TYPE	synthetic, monocrystalline synthetic, polycrystalline (natural on request)
Diamond grain sizes	of 0.25µm–15µm larger only on request.
Binding agent	A = alcoholic, low viscosity O = oil-soluble, low viscosity
Packaging	Standard pump bottle with spray head for fine metering. The bottles are welded in PE film for protection.
Example order	1 x 200ml dia-plus diamond spray TYPE A

liqui-plus diamond suspensions

Under the registered trademark liqui-plus, we produce high quality diamond suspensions for a wide range of application fields, such as laboratory areas and mechanical lapping and polishing. The following also applies here: We only process top quality diamond grain sizes from natural diamond, synthetic monocrystals and synthetic polycrystals - none of which are recovered from used grinding tools.

Furthermore, diamond grain sizes disperse agglomerate-free - i.e. without the clustering of individual particles - in selected liquids. The settling of heavy diamond particles is delayed through the addition of stabilisers and this supports the high product removal rate.

Various requirements are placed on the suspension, depending on the processing task. We offer five standard binders, although these can be further modified by you.

TYPE A	Alcoholic binder with very low viscosity. This version is not suitable for machine applications
TYPE DP	An alcoholic binder with high viscosity. This type forms a good, resistant lubricating film
TYPE W	An aqueous binder with a high degree of purity and low viscosity
TYPE W/S	An aqueous binder with moderate viscosity, stabiliser and rust protection
TYPE O	Oil-based binder. However, this can be adjusted in the standard version with low viscosity. TYPE 0 delivers a very good lubricating film, high removal rate and very good corrosion protection.

 

The liqui-plus diamond suspensions are supplied in PE bottles with dropper closure and are additionally welded in PE film. Furthermore, delivery in 5-litre canisters is also possible.

Diamond concentrations
The diamond particles are very highly concentrated in the variants of liqui-plus diamond suspensions for laboratory areas: In this way, an outstanding diamond concentration is also guaranteed over small processing areas.

Our standard suspensions for machine applications are also very highly concentrated. Because a lower proportion of diamond is frequently sufficient with many processing tasks, we are also able to reduce the concentration in accordance with your requirements and offer you a tailored product.

dia-plus fluid – thinner for our diamond pastes

Some work demands the sparing thinning of dia-plus diamond pastes. This includes work on hard lapping and polishing workpieces such as brass, copper or Plexiglas, which require a stable lubrication layer in which the diamond particles can roll freely, although not agglomerate.

The dia-plus fluid has been specially developed for this thinning. It can be applied with a metering syringe (available from all pharmacies) or, with large-area application, with our utility model-protected single-handed sprayer. Our diamond pastes should not be thinned for polishing works with felt, cloth discs, etc. because this reduces the removal rate, lengthens the polishing process and the risk of relief forms (orange peel skin) on the workpiece is increased.

Our range of products includes:

TYPE A	Alcoholic mixture, miscible with alcohol and water in all ratios.
TYPE O	Ultra-pure mineral oil mixture with low viscosity.
TYPE W	125 ml dropper bottle 125 ml single-handed sprayer 1000 ml dropper bottle 5000 ml canister

dia-plus multi-mix

dia-plus multi-mix is a universal product that is used in the workshop, in domestic applications and in hobby areas: It loosens, cleans, maintains and forms a thin protective film against corrosion and mechanical wear.

Due to its moisture creeping properties it enables the establishment of improved contact with connections, circuit boards, relays, etc. Furthermore, it is possible to thoroughly remove lime residues, gummy grease and oil deposits, disinfectant residues, rust on machine parts or boiler scale on sanitary fittings.

dia-plus multi-mix is a superb additive for the lapping and fine grinding of metal workpieces, and with the use of ceramic grinding and polishing stones. It is free of silicone and acid, so that metals and paint coatings are not attacked. dia-plus multi-mix is also indispensable for the regular maintenance of our devices.

Packaging units	500 ml spray bottle 5000 ml canister
