About TTB Engineering
TTB Engineering SA is a manufacturer of high-precision tool grinding machines headquartered in Riva San Vitale near Lugano, Switzerland. The company develops and manufactures CNC tool grinding centers in 5- and 6-axis configurations as well as custom special-purpose machines and robotic cells for the grinding process. The machines produce rotary tools, gear hobbing tools and indexable inserts with diameters from 0.01 to 40 mm in micrometric tolerances (0–3 µm) in solid carbide, HSS, CBN, ceramics and other materials. The offering also includes application technology such as custom clamping systems, steady rests, measuring systems with laser and probe technology, loading units, as well as cylindrical grinding and regrinding services. TTB Engineering has been a member of the SAACKE GROUP in Pforzheim (DE) since 2007 and supplies industries such as automotive, watchmaking, medical technology, dental technology, aerospace and micromechanics.

Additional services
Quality
The machines operate with workpiece and wheel palpers, 8 temperature sensors and high-resolution optical scales and guarantee repeatability below 0.3 µm (tool positioning within 1 µm). Micrometric tolerances in the 0–3 µm range are consistently maintained even over long production runs without operator intervention.
