The Choice for Grinding Hard Materials

At Reparex our focus is on providing our customers with a one-stop-shop for wear resistant solutions. In many precision applications we have helped our customers by replacing abrasion resistant steels with precision ground monolithic ceramics, thermal spray coatings, brazed tungsten carbides or AeroTech Bonded ceramics. With our in-house machining and grinding capabilities we are able to modify existing parts to accept any specified coating or lining, which then can be ground to meet precision machine tolerances.

Schneider ID / OD and Surface Grinder

Our Schneider grinder offers some unique large capacity capabilities for diamond grinding very hard materials. Our equipment is capable of grinding the ID and OD of pieces and has a completely separate head for surface grinding. This set-up allows us to complete both surface grinding and ID or OD work at the same time. Also, both the ID/OD and Surface grinding heads can be angled to allow us to complete chamfering work or work on conical pieces. The grinder table is 48” in diameter and the machine is capable of swinging parts as large as 76” in diameter. The unit is able to work up to a full 41” under the rail making our ability to handle large piece work quite unique.

Other Large Capacity Machines

• Landis 30” x 120” Universal Cylindrical Grinder
• Thompson 24” x 72” Surface Grinder

Our Machining & Diamond Grinding Experience

We have deep project experience diamond grinding very hard materials including: Tungsten Carbides, High Alumina Ceramics, Reaction Bonded and Nitride Bonded Silicon Carbides, as well as the spectrum of thermal spray coatings. We have application know-how to match the correct diamond tooling to the characteristics of the wide variety of hard materials we are to offer. We are confident we can meet your specific application needs.

Other Diamond Grinding Capabilities

In addition to our large capacity equipment we are able to offer diamond grinding services for a variety of smaller wear parts. These include ID & OD grinding, as well as surface grinding for smaller precision components such as valve gates, valve seats, pump shaft sleeves, pulverizer mill liner walls and plates, screw conveyors and shaft seals to name just a few.

Rotary Airlock Rebuild, Lining and Grinding

If your current Rotary Airlock units see continual wear from abrasive materials let us help you prevent down time and loss of efficiency. We specialize in repair and retrofitting of Rotary Airlocks with ceramic and tungsten carbide linings, as well as thermal spray coatings. With our unique grinding capabilities we are able to either retro-fit or rebuild any sized rotary airlock and provide a precision ground ceramic or tungsten carbide liner to optimize both the performance and the useful life of your rotary airlocks. Let us help you find a liner that can meet your specific application needs.
