About KOSAKA Machines
KOSAKA is the equipment brand of Kosaka Laboratory Ltd., a Japanese manufacturer headquartered in Tokyo. Its precision measurement business focuses on evaluating surface texture, contour, roundness, cylindricity, micro-scale profiles, and three-dimensional geometry. The company also produces hydraulic equipment and specialized automation, but its surface metrology instruments are particularly relevant to buyers of used industrial inspection equipment.
KOSAKA surface roughness machines use contact stylus measurement to trace a workpiece and calculate parameters under standards such as JIS, ISO, DIN, and ASME, depending on the model and software configuration. Combined roughness and contour systems extend this capability to profile, radius, angle, step-height, and form measurements. The EC series uses precision rotary-table arrangements, including air-bearing systems on many models, to evaluate roundness, cylindricity, concentricity, flatness, and related geometric characteristics.
These systems serve quality laboratories and production environments inspecting shafts, bearings, pistons, precision-machined components, electronic materials, wafers, display components, and optical parts. KOSAKA equipment receives attention on the used market because specialized metrology systems can represent a significant new-equipment investment. A properly configured pre-owned unit can expand inspection capability, provided its detector, mechanical axes, reference standards, software, and calibration status remain suitable for the buyer’s measurement requirements.
