3D-Printed Workpiece

This is what our bottle opener should look like after it has been 3D printed.

Description

3D-Printed Workpiece

To process this bottle opener, we chose our High-Speed Centrifuge Systems.

First it was grinder and after polished.

Description

How can the mirror shine be achieved?

Polished with walnut shells and different compounds. To achieve a high gloss, multiple polishing steps in a High-Speed Centrifugal Machine are required. Depending on the desired result and surface condition, this may require between three and five cycles to reach the high gloss finish.

Before

Titanium Workpiece

Task: Remove milling stripes and polish

Description

Processing of Titanium Workpiece

We worked on the titanium workpiece in two 60 minute cycles. First, the workpiece was grinned and milling stripes were removed. The second cycle involved polishing. The process took place in one of our High-Speed Centrifugal System, using a combination of wet and dry process.

After

Satin Finish

Workpieces after processing

Before

Satin Finish

Task: a matte shine should be created

Description

Satin Finish

Processing was done in using a dry process in a Round trough vibratory machine with special nugget-shaped media. The special feature of this media is its matte surface with a beautiful, satin-like shine. Processing can also be carried out in High-Speed Centrifuge Systems.

Processing in our High Speed Centrifugal Machine

1. Wet process with plastic cones

2. Dry process with walnut shells and compound

After

Grinding and Polishing of Plastic Part

A smooth surface could be achieved

Before

Grinding and Polishing of Plastic Part

Roughness is clearly visible.

Description

Grinding and Polishing of Plastic Part

Grinding and polishing in two steps using wet process.

The selection of abrasives and equipment depends on the nature of the workpiece.

After

Deburring of Rings with a Thickness of 2 mm

Grinded and deburred

Before

Deburring of Rings with a Thickness of 2 mm

Burrs are clearly visible

Description

Deburring of Rings with a Thickness of 2 mm

Depending on the material thickness, alloy and workpiece size, different grinding media were used, which differed in shape and properties.

Textile Machinery Industry

Spare parts for textile machines can be successfully grinned; even very narrow and angled areas can be processed and the surface can be rounded and smoothed.

Electronics: Deburring Copper Components

Deburring copper components is possible with ceramic media and our High-Speed Centrifugal System. One cycle takes 15–30 minutes.

Polishing very High-Quality Temples

As with brass instruments, high-quality designer eyeglass temples can be finely grinned and polished to high gloss in 2-3 steps.

Without workpiece picture

Medical technology: dental implants/knee prosthesis/hip prosthesis

Removing milling stripes, grinding and polishing of 3D printed components in different sizes, textures and shapes.

Without workpiece picture

Medical technology: components from highly sensitive areas

Our High-Speed Centrifugal Systems and our specially manufactured grinding media are also suitable for these applications. The grinding media and systems have been specifically concerted for this application.

Without workpiece picture

Automotive industry

Our media and systems are used in various automotive sectors. Processing of particularly small components is possible.

Without workpiece picture

Rolling bearings/ball bearings/valves

Surface roughnesses of less than 0.3µm can be achieved.

Without workpiece picture

Polishing of zinc-coated components

Used in medical technology, components can be polished with a wafer-thin layer of zinc to protect them from bacteria.

Without workpiece picture

Food industry

Our grinding media are also in this sector. Their high grinding performance produces a homogeneous, smooth surface. Large and small components can be reduced from milling stripes and prepared for electroplating.
