Particular Challenge: For the assessment of rotating parts, numerous parameters have to be taken into consideration: Concentricity, radial run-out and axial run-out (i.e. wobble); furthermore thickness, diameter, planarity and the absence of surface defects had to be examined. The solution developed by QuellTech consists in a configuration of three Q6 Laser Laser Scanners.Each of the lateral surfaces is assigned to its own scanner. In order to enable the thickness precisely to be determined, both laser lines are mutually oriented in opposite direction. The third scanner inspects the outer circumference of the wheel, this way measuring diameter and radial run-out. All of these scanners are subject to encoder signals supplied by the rotary axis and synchronously triggered, so possible defects on the wheel can precisely be localized. The measurement takes place at a resolution of ca. 30 µm, and a cloud comprising several millions of points are obtained.

The choice of the right serrated grinding wheel for grinding knives, scissors, tweezers, pliers, surgical instruments, etc. with the most suitable teeth and the highest quality standards must be determined on a customer-specific basis depending on the intended use. The base body of the serrated grinding wheel is made of aluminum. A coating is applied to the aluminum body, into which the teeth are then inserted depending on the profile shape according to the intended use. With our many years of experience, we would be happy to advise you by telephone or on site regarding a high-quality and cost-effective design of a serrated grinding wheel for your process.

Mixed alumina type WIWOX® RK has a low ferrite content and is particularly suitable for applications where a high consumption of blasting abrasives cannot be avoided. Mixed Alumina is produced from ceramic grinding wheels and reclaimed alumina dust from the blasting and grinding industry. It consists of a mixture of white, pink and brown alumina, and is an iron-free alternative for many sectors of the blasting and grinding industry.

When processing sheet metal parts by punching, lasering, plasma cutting, flame cutting, etc., a burr is always created. We have met the challenge of deburring or rounding these “sharp” edges of the workpieces in companies by developing our deburring grinding wheels and deburring rollers. By using these highly flexible tools, both on hand machines and on automatic machines, sheet metal parts can be optimally rounded or deburred. We have the right dimensions for your deburring machine! We would be pleased to advise you on which deburring rollers can be used in your processing, in order to achieve top process results.

Uniformly wide polyurethane lamellae are attached in precisely established spacing while plastic foam lamellae are attached in the spaces between them to the aluminium hub of the frequency damped contact wheel FAPI-KS/V FREQUENCY DAMPED. The height of the coating resp. the length of the polyurethane and plastic foam lamellae can be varied depending on the application (standard: 25 mm). The positioning of the lamellae dampens the howling sounds in the upper frequency range in the contact wheel coating during grinding so that they are no longer audible to the human ear. The contact wheel FAPI-PUS/KS frequency damped achieves a significant reduction of the noise level in the workplace and so contributes its share to work safety. Benefits of contact wheels with polyurethane foam lamellae: Highly elastic (adaptable) Wear-resistance Oil-resistance Grease-resistance We will be happy to advise you in order to find a suitable contact wheel for you.

The contact wheel FAPI-PUS/KS is an extremely soft version of a contact wheel with a polyurethane foam and plastic foam lamella coating. The overall height of the coating must also be selected based on the respective application. The alternating polyurethane and plastic foam lamellae make the contact wheel extremely soft and particularly adaptable. In practice, this contact wheel is used mainly for the finishing of strongly cambered or rounded workpieces. Because of the different material densities and the spacing between the lamellae heat dissipates very well during the grinding process. Advantages The contact wheels of the FAPI-PUS – series are coated only with polyurethane foam lamellae. Benefits of contact wheels with polyurethane foam lamellae: Highly elastic (adaptable) Wear-resistance Oil-resistance Grease-resistance We will be happy to advise you in order to find a suitable contact wheel for you.

The contact wheel FAPI-PUS OPEN is a further development of the dense design. Here the aluminium core is coated alternately with a long and short polyurethane foam lamella. The overall height of the coating is also adaptable to the respective application and is therefore variable (standard: 35 mm). Because of the variant of the open design, the abrasive belt can better cool because the heat from the belt sanding process is better dissipated. Through the precise adaptation of the extremely soft running cushion to the workpiece that shoud be found it is possible to achieve high-performance results when finish grinding. Advantages The contact wheels of the FAPI-PUS – series are coated only with polyurethane foam lamellae. Benefits of contact wheels with polyurethane foam lamellae: Highly elastic (adaptable) Wear-resistance Oil-resistance Grease-resistance We will be happy to advise you in order to find a suitable contact wheel for you.

With the contact wheel FAPI-PUS DENSE, the aluminium hub is coated with dense adjoining polyurethane foam lamellae. The height of the coating resp. the length of the polyurethane foam lamellae can be varied depending on the application (standard: 20 and 35 mm). The polyurethane foam lamellae provide the contact wheel with a “running cushion” with which a fine finish is possible especially when working on (strongly) cambered and profiled parts. The coating adapts to every workpiece to be found. In addition, the contact wheel FAPI-PUS dense contributes in large measure to abrasive belt cooling because the spaces between the lamellae dissipate the heat generated during belt grinding.

The gauges from the VSL Series measure the form, diameter, roundness and eccentricity of the rolls during the grinding process with very high precision. Form, radial run-out and eccentricity are measures with a precision of ± 1 µm. If an interface is available, they communicate online with the controller of the roll grinding machine and thus enable even more cost-effective use of the grinding machine. With the appropriate configuration, they measure the height and lateral alignment of the roll in the grinding machine before grinding, often enabling the set-up time to be significantly reduced. Vollmer produces the automatic roll measuring gauges for both bench-mounted machines where the roll is moved along the grinding wheel and for support machines where the grinding wheel is moved along the rotating roll. Vollmer supplies the systems for a broad spectrum of roll diameters.
