FOR SALE / ref rac27022026 CAMSHAFT GRINDER TITAN RAC 500 X 1500 The technical architecture of the RAC 1500 is centered around a monolithic cast iron base, a design choice intended to provide maximum structural rigidity and dampen vibrations during the grinding process. This stability is critical for maintaining the dimensional accuracy required for cam profiles. The machine features a center height of 130 mm over the table and a maximum swing diameter of 260 mm, allowing it to handle a wide variety of camshaft sizes for both passenger and commercial vehicles. The machine is engineered to meet stringent tolerances, often maintaining dimensional accuracy within ±0.01mm and achieving surface roughness levels as low as 𝑅𝑎 0.2 𝜇m. Key physical specifications include: Maximum Distance Between Centers: 1,500 mm. Center Height over Table: 130 mm. Maximum Grinding Diameter: 260 mm (over table). Grinding Wheel Dimensions: The machine utilizes a wheel with a maximum diameter of 457 mm, with widths ranging from 20 mm to 32 mm. Workpiece Weight Capacity: While specific to the model configuration, similar Titan-class conventional grinders in this size range typically support workpieces up to 300 kg. Operational Features The RAC 1500 employs a hydraulically controlled grinding head feed system, which facilitates automatic micrometric adjustments. This is essential for "cam profiling," where the machine must follow a specific master cam or programmed path to regenerate the lobe shape of the camshaft. The control system often includes integrated gauging devices to check the straightness of the shaft and the stroke of the cam during the operation.
