From roughening to high-gloss polishing
Grinding and polishing tools with bonded abrasives
The combination of abrasive grains and matching bonding agents results in many different compact and powerful tools. Depending on the combination, they can achieve any kind of surface finishing – from intensive material removal through to gloss polishing.
With many abrasives, the abrasive grains are embedded in a bonding agent and applied to different backings. This combination of different abrasive grains, bonding agents and abrasive materials results in a huge variety of possibilities. LUKAS’ know-how and manufacturing quality turn these into a system of grinding and polishing tools that has a solution for practically every machining job.
LUKAS tools with bonded abrasives tools comprise four categories:
We offer an enormous variety of mounted points. The range covers 15 grain qualities, up to 13 head shapes, synthetic resin or ceramic as bonding agent, and head diameters between 2 and 50 mm. Depending on the type, the mounted points are suitable for different materials and machining stages, and for coarse to fine machining. What they all have in common are the standard LUKAS quality and long tool life.
Choosing the right mounted point is simple:
- Select the machining material such as steel, cast materials, non-rusting steels, non-ferrous metals, etc.
► Abrasive grain and matrix will be shown according to your selection. The machining method – from rough cutting to fine grinding – is stated for each mounted point.
- Choose a head shape depending on your machining requirements
► Each mounted point is available in various shapes.
- Select the appropriate head size
► Mounted points are available in both metric and imperial dimensions.
This simple schema will help you find the right mounted point straight away.
A large range of polishing tools is also available. The differences lie in the base material, the grinding wheels, the shape and the hardness. LUKAS has divided the grinding materials into seven classes from P1 to P7 for a simple overview. In these classes, the polishing materials are assigned to the desired results. You have the following choices:
- dash-dot matting
- matt finish
- mirror finish
Select the appropriate abrasive from a matrix. Each abrasive is available in different forms such as a point, stick or disc. This makes them easy to use on the respective workpieces.
Felt polishing points are used for polishing complex-shaped workpieces. Their high elasticity lets them grind grooves, bores and other tight spaces. They are designed to be used in a wide variety of jobs: machining pressure and injection moulds, drawing, pressing and cutting tools, cold impact dies, dies, bearings, spindles, rollers and calibres.
LUKAS felt polishing points are available in two qualities: H3 and H3-S (super hard). Based on its many years’ experience, LUKAS has developed grinding wheels that meet all the usual requirements. This allows you to choose from five types of felt polishing pins in different sizes. Also available is the S1 felt polishing disc and matching clamping bolt for machining larger workpieces.
Sanding and diamond pastes enable metals to be quickly ground to achieve a high gloss finish. Our versatile grinding pastes contain silicon carbide in the grit sizes 320 to 120. This material expedites the machining of steel, cast iron and non-ferrous metals. It is excellent for grinding workpieces by hand. It demonstrates its versatility not only on steel and cast materials, but also on non-ferrous metals.
Diamond pastes are mainly used for machining hardened steels, stainless steel and titanium, as well as other very hard metals. They can be effectively used with both manual tools and robot systems. Monocrystalline diamond pastes achieve the best results at a hardness of 50 to 70 HRC. The very latest product in this category are polycrystalline diamond pastes. These continually produce new sharp cutting edges due to predetermined breaking points in the diamond cutting edges. This makes them incredibly productive. They are used on steels and titanium with a hardness of more than 60 HRC. Their high process reliability and economical consumption make them the first choice for polishing with NC machines and robot systems.
