Above: The TTSC model range is the most compact of all Weber grinding machines
January, 2026- In most industries, tight-tolerance parts are crucial to achieve performance and durability goals-and just one small burr can have a negative effect on fit or surface finish. Sharp edges also can create hazards for operators during the handling and assembly process.
Named after its founder and now run by the fourth generation of the family, Hans Weber has been developing and manufacturing grinding machines for over 100 years. The company introduced its first metal grinding technology in 1983-a machine that featured a pin sanding beam to press the belts evenly against the sheet metal parts and achieve consistent sanding quality. Based in Kronach, Germany, with U.S. sales and service in Paola, Kansas, Weber builds deburring machines that meet a variety of requirements and handle parts processed via punching, laser, plasma or other cutting methods.
UPGRADE
Contract fabrication and machine shop Newswanger Machine, Shiloh, Ohio, serves such markets as water treatment equipment, agriculture and trucking, among others. “We also do laser cutting for other local fabrication and machine shops,” says Marlin Newswanger, general manager.
Newswanger learned about Hans Weber “from Fabtech and our local dealer, FMS Machinery. We selected a TTSC1100 sander and deburring machine and have had it for about a year and a half.”
Prior to installing its TTSC1000, the company was deburring its carbon and stainless steel and aluminum parts by hand, using grinders and other hand tools, but sought to streamline the process. Machines’ advantages over hand processing include greater efficiency, making quick work of large volumes, consistent, more precise results, less labor intensity and greater operator safety.
Grinding rollers are available with different diameters and rubber hardness.
According to Hans Weber, when selecting a grinding machine, companies should consider the type and size of the parts to be processed, desired surface quality, required processing speed, available space in the production environment and budget for both purchase and ongoing maintenance.
The TTSC1100 machine is useful for companies like Newswanger that process many different types of parts. It comes in a compact housing and can handle deburring, rounding, descaling, slag removal and surface grinding on parts from 0.3 to 100 millimeters thick—even combining processing steps to meet customer requirements.
Newswanger says key features of the TTSC are the “two-stage abrasive belt and edge rounding brushes, the thickness measuring tool, and the optional dust collector that is safe for both aluminum and steel.” Other specs include three grinding stations, a grinding belt drive up to 19 kilowatts and adjustable feed speeds from 1 to 10 meters per minute.
STAY IN CONTACT
For surface finishing, the Weber equipment offers three grinding stations. A grinding roller achieves surface finishing and deburring in a single operating sequence. According to company literature, “The grinding pressure is generated by positioning the roller downward below the zero level. When the roller approaches the workpieces, the rubber coating of the roller is pushed inward.”
The force of this motion contributes to the grinding action, and rollers are available with different diameters and rubber hardness to adapt to all types of parts. The precise control and positioning also allow for flexible adjustment of the grinding pressure to accommodate various workpieces. The unit is equipped with electric adjustment and can be accurately positioned and readjusted during operation.
The planetary head has several rotating brushes arranged in groups to provide the ideal angle on the workpiece and overlap to ensure there are no gaps. The STC bolt grinding beam has a long contact surface with the workpiece to tackle all edges without creating secondary burrs. Th beam is pre-tensioned to compensate for existing thicknesses between one part and another and makes simultaneous feeding of small parts possible.
“One job we do is an aluminum flange with runs over 2,000 parts, and our customer requires that the laser burr is removed,” Newswanger says. “Before we had the Weber, it was very time consuming, and our operators don’t like doing deburring so the job was often running late. Now, the TTSC does the parts quickly, and they look better and more consistent. We regularly have customers requesting that we run the parts we cut for them through the Weber since it makes them look better-and they are no longer sharp.”
