LOESER prides itself in innovation using the latest technology in machine controls and mechanical components. LOESER’s product line has been recently expanded with new solutions for extremely high stock removal, Continuous through feed induction hardening, Continuous through feed chrome plating

Extremely high stock removal technology

Recently LOESER has developed new technology for extremely high stock removal applications on tube and bars made of different materials including carbon steel, stainless steel, special alloys, Inconel and similar type of materials. LOESER centerless belt grinding machines RPS 376 and RPS 377 offer much faster stock removal than a standard turning operation.
This process is successfully used by companies such as ThyssenKrupp Elevator (USA),V&M Deutschland GMBH (Germany), Salzgitter Mannesmann Stainless Tubes France S.A.S. (France), Zlatoust Metallurgical Works (Russia), DSS Elektrometallurgical Works Dneprospetstal (Ukraine), BÖHLER Edelstahl GmbH & Co KG (Germany), Bao Steel Group Steel Tube Co. (China), Jiuli Stainless Steel Pipe Co.,Ltd (China), WuLiangYe AnJi, Wilhelm Schulz GmbH (USA), Carpenter Technologies (USA), Tenaris Dalmine S.p.A (Italy) etc., KEPCO ( Korea).... Global Nuclear Fuels Hitachi (USA),

Continuous through feed induction hardening
LOESER continuous through feed induction hardening systems are successfully used by such companies as INA SCHAEFFLER (Germany), Stelmi (Italy), IHC Industrial Hard Chrome (USA) and Pacoma Hydraulic Equipment Co., Ltd. (China), BOSCH REXROTH.

New Loeser innovations:

Continuous through feed chrome plating
LOESER’s product line has been recently expanded to include complete continuous through feed chrome plating systems. LOESER through feed chrome plating systems are successfully approved by such Companies as Exxelin (Germany) and Pacoma Hydraulic Equipment Co., Ltd.(China), OGISO ( JAPAN), TAVILLER ( TURKEY ) and many more companies where confidentiality agreements don’t allow to show the reference....

LOESER offers technologies for centerless stainless tube mirror polishing/buffing. The design of the machine is based on abrasive belt polishing combined with cotton wheel buffing using a polishing compound

In addition to standard belt grinding and polishing machines for round and flat parts, LOESER provides creative solutions for micro finishing up to 0,004 µm Ra.

Pressure Controlled grinding and polishing combined with new Loeser innovations make LOESER the only producer of surface finish technology systems capable of offering all of the following solutions:
• through feed induction hardening
• through feed belt grinding and finest polishing before plating
• through feed continuous chrome plating
• through feed polishing post chrome
• Through feed wax buffing for added corrosion resistance.

Careful and accurate evaluation of each customer’s specific requirements is Loeser’s highest priority. The accumulated knowledge from many years of process development and innovative thinking is key. This is absolutely critical in order to construct large complex automated systems.
A complete Loeser System can be installed and running at a customer’s plant in a remarkably short amount of time. LOESER’s customers greatly benefit from LOESER’s decades of experience in developing thousands of grinding processes.
