Product Specifications

Technical details and manufacturing context for Cross Feed Mechanism

Definition
The cross feed mechanism is a critical component of a surface grinding machine that enables precise lateral positioning and movement of the grinding wheel or workpiece table perpendicular to the longitudinal feed direction. It ensures uniform material removal across the entire surface width during grinding operations. The mechanism typically consists of a lead screw, nut assembly, handwheel or motor drive, and guideways. Rotation of the handwheel or motor drives the lead screw, which moves the grinding wheel carriage or workpiece table laterally along precision guideways. Manual or automatic controls allow for incremental or continuous cross feed adjustments. The mechanism is designed to handle maximum table travel from 300 to 1000 mm, feed rates from 0.1 to 10 m/min, and positioning accuracy of ±0.005 to ±0.02 mm, with repeatability of ±0.003 to ±0.01 mm. It can exert a maximum feed force of 5 to 20 kN, powered by a motor of 0.5 to 3 kW, operating at 220 to 480 V AC (three-phase, 50/60 Hz, per IEC 60038). The operating temperature range is 0 to 45 °C, and the protection class is IP54 to IP65 per IEC 60529. The guideway type is linear rolling guide, and lubrication is automatic. Net weight ranges from 200 to 1500 kg. Materials used include alloy steel, cast iron, and bronze. These values are reference ranges for typical configurations; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The mechanism is essential for achieving consistent surface finish and dimensional accuracy in surface grinding operations.
Working Principle
The cross feed mechanism operates by converting rotary motion from a handwheel or motor into linear motion via a lead screw and nut assembly. The lead screw is coupled to the grinding wheel carriage or workpiece table, which moves laterally along precision guideways. Manual operation uses a handwheel for incremental adjustments, while automatic systems use a motor drive for continuous or programmed feed. The guideways, typically linear rolling guides, provide low friction and high rigidity, ensuring smooth and accurate movement. The feed rate and positioning are controlled by the operator or CNC system, allowing for precise lateral positioning across the workpiece width.
