Range of application
The Nearly every automobile manufacturer is in
the processof downsizing its passenger cars’ engines. Small displacement engines
are lighter and have reduced friction loss, thus making them more fuel efficient
and able to meet more stringent emission limits.
To achieve this technically, tomorrow’s crankshaft bearings will need to have
smaller diameters and lengths, and will often need to be harder — resulting in
higher stresses and strains due to increased pressures. Thus, the surfaces of
the main and pin bearings will require more precise microgeometry.
Rising to this manufacturing challenge, Supfina has created a new machine line:
the Supfina CenPro S. It combines high workpiece quality with short cycle times,
not to mention a smaller footprint and lower operating costs.

The Supfina LCM Crank was developed to
complement the high-production CenPro and the CenFlex series crankshaft
finishing machine and can be quickly changed over to accommodate a variety of
workpieces.
It’s also the perfect machine for those who want to superfinish critical
crankshaft surfaces (for example, main, connecting rod, thrust bearings, and oil
seal) in small to medium volumes.

That’s because the LCM Crank can be conveniently equipped
with the right finishing modules for each machining task.
Up to six Supfina attachments (either permanently mounted, manually adjustable,
or numerically controlled) can be used simultaneously, including stone- and
tape-finishing units as well as deburring and polishing devices.
Equipped with the latest machine technology, the LCM Crank’s modular system
meets the quality and process reliability needs demanded by the automotive
industry and its suppliers.
In addition to “simple” shaft geometries such as transmission, balancer, cam,
and eccentric shafts, a crankshaft’s main and connecting rod bearings can also
be easily machined. Just about any material — from soft iron to hardened steel —
can be finished.
LCM Crank series machines can be loaded and unloaded manually, by gantry loader,
or by robot — thus guaranteeing cost-effective part handling for single-unit or
small-run production.
Deep-groove ball bearings, angular ball bearings, cylindrical roller bearings, tapered roller bearings, self-aligning roller bearings: There is almost no limit to the types and sizes of bearings that are used in a wide range of industries.
When it comes to perfect surfaces, there is almost no limit to the solutions that Supfina can offer. Our superfinishing machines more than fulfill our customers’ requirements in terms of economy, versatility, reliability, and quality.
Our unceasing commitment to development work — in cooperation with the antifriction bearing industry — ensures that Supfina technology remains on the cutting edge.
Bearings reduce friction — and we reduce friction in bearings.
„From needle bearings in electric motors to roller bearings in offshore wind farms - Supfina develops and produces solutions for the precise machining of rings and rolling elements.“
Flexibility, reliability, safety and highest machining quality have always been the values of the Supfina machines Race, RacePro and RaceFlex. The new Supfina RaceNeo combines these values with the demand for highest machining quality and increasing requirements regarding economic efficiency in series production at the same time.
Time is money. That old adage applies to the road as much as it does to production. Yet time is not everything: Quality must be perfect as well.
Supfina’s throughfeed-finishing machines help to achieve high production rates with minimal work effort, thanks to reduced retooling times and long service lives for the tools.
But unparalleled quality also is a must — and Supfina delivers. By finishing antifriction bearings, piston rods, and cams to perfection, our machines keep cars and trucks moving smoothly on our roads. And that achievement keeps our customers happy.
Dams, refineries, pipelines, and chemical plants: All of these environments must control fluids and gases. Thus, they require reliable fittings, of which the ball valve is at the heart. That’s because ball-shaped surfaces are the ideal shape for accurately controlling technical processes of this kind.
They must be leak-proof, withstand tremendous loads, and have the ¬longest possible service life. These requirements can be met only if the surface is perfect — and Supfina’s technology makes that perfection possible.
Replacing a hip joint is not as easy as changing a washer in a leaky tap.
From the outset, everything must fit perfectly. Of course, the surgeon’s skill is integral to ensuring that, following the operation, the patient moves freely and without pain. But also crucial is the quality of the artificial femur head and ace¬tabulum, both of which must be finished to an extremely high standard of accuracy.
In many cases today, the preferred material for hip replacement parts is ceramic, which requires very specialized processes and is more difficult to finish than steel. But by using Supfina’s superfinishing technology, we can achieve the high quality that is necessary for these ceramic parts.
Perfection is achieved when the final finishing touches have been applied. In the automotive industry, components must meet the most exacting standards so that, in tough day-to-day running, parts can last for the maximum time.
Whether the part’s surface is flat or curved, our machines achieve the best possible finish. This result is crucial for load-bearing sealing surfaces, because perfect finishes make parts virtually wear-free and tough enough to last.
While our flat finishing machines can give a component the surface perfection it needs, that’s still not enough for us. With each improvement it becomes more difficult to make our machines even better — but this ongoing pursuit of excellence is a challenge that we’re happy to embrace.

Accurate flat surfaces are often required even if the workpieces they belong to are not visible. In household appliances, in entertainment technology, in the manufacture of clocks and watches, in the automotive field – nearly every product today contains small, flat parts.
Due to the high demands made on tolerances, evenness and parallelism, the workpieces have to be ground to a very precise degree to enable them to perform as intended. They are often components that the user never sees but which are essential so that the clock, watch, pump, gearbox and car function properly. The manufacturing process requires both quality and economical processes to be in the foreground.
This is where Supfina is setting new standards. Our double-disk grinding technology enables high product quantities to be machined to consistently high standards in the shortest possible times. The result is workpieces with high surface quality, evenness and parallelism while adhering to the tightest of tolerances and keeping costs per part to a minimum.
