Condition: new, Year of construction: 2026, Take advantage of our portfolio of plastic abrasive media for processing softer materials such as brass, copper, or aluminum. Plastic abrasive media offer a gentler and less aggressive treatment. Like ceramic abrasive media, plastic abrasive media are available in a wide range of grit strengths, shapes, and sizes. We select the optimal media for your components and processes to ensure the best results. Overview of the different geometries and their properties: - Cones (K) have a high mass, resulting in efficient material removal. Their rounded shape enables gentle processing. - Pyramids (P), with their edges, are ideal for deburring operations. Thanks to their pointed design, these media can reach difficult areas such as boreholes. Dksdpfx Asyq N S Nskgen - Tridents (DZ) are especially suitable for processing complex components, such as gear parts or workpieces with grooves. - Paraboloids (PA), similar to cones, use their rounded shape to excel at smoothing and polishing, delivering gentle and even surface treatment. - Lenses (L), with their lower weight, are well suited for soft materials and deliver gentle and consistent material removal. - The Wedge (K), thanks to its versatile geometry, is an optimal abrasive for deburring. Its pointed shape means it can easily access narrow slit areas. - Tetrahedrons (T) function similarly to pyramids, with their edges providing efficient deburring. Their sharper corners allow them to better access complex areas. As an experienced partner, we provide expertise in the field of vibratory finishing. Together with you, we develop efficient solutions to achieve optimal process results. If you are interested, we look forward to hearing from you. We will gladly provide you with non-binding advice. The European Commission provides a platform for out-of-court online dispute resolution (ODR platform). This offer serves solely as an online presentation of our products. Contract negotiations take place via telecommunications (e-mail, telephone, messaging platform). We will initially send you a non-binding offer, which will also include our general terms and conditions with legal notice and information about your right of withdrawal, before any purchase or contract is concluded.

Condition: new, Year of construction: 2026, Discover our extensive range of high-quality, cost-effective ceramic grinding media for processing workpieces made of steel, stainless steel, or other hard materials. Ceramic grinding media are distinguished by their outstanding durability. Dkodpfx Aksyq N N Isgon Ceramic grinding media are particularly suitable for working with hard materials such as steel, but are also ideal for deburring aluminium parts. Due to their higher weight, they exert greater pressure on the workpieces and deliver excellent grinding performance. Compared to plastic grinding media, they are significantly more durable and cost-efficient. When selecting the right grinding media, it is important to find the optimal configuration in terms of grinding performance, surface finish, geometry, and size. - Triangles & Triangular Bevel Cut (D & DS): Ideally suited for deburring thanks to their edges, but also reach a variety of complex areas on workpieces. - Tridents (DZ): Access even hard-to-reach areas, such as grooves or gear wheels. - Cylinders & Cylindrical Bevel Cut (Z & ZS): Their round shape makes them ideal for achieving a uniform surface finish, e.g. in polishing processes. Cylinders are generally easy to separate due to their slim design. - Ellipses & Elliptical Bevel Cut (E & ES): Suitable for polishing and smoothing; their tips enable them to reach deeper areas of the workpiece. - Wings (W): Combine the advantages of triangles and tridents. Their "wings" reach complex areas, while their edges and compactness make them excellent for deburring and ensure good pressure on the workpiece. As an experienced partner, we provide expertise in all aspects of vibratory finishing. We work with you to develop efficient solutions for your optimal process results. If you are interested, we look forward to hearing from you. We will be happy to provide you with professional and non-binding advice.
