Vertical Feed Mechanism for Surface Grinding Machines

Product Specifications

Technical details and manufacturing context for Vertical Feed Mechanism

Definition

The vertical feed mechanism is a critical component of a surface grinding machine that precisely controls the downward or upward movement of the grinding wheel head or workpiece table. It enables accurate depth of cut adjustments during grinding operations, ensuring dimensional accuracy and surface finish quality of machined parts. This mechanism is typically composed of a lead screw, nut assembly, handwheel or motorized drive, and precision guides. Rotation of the handwheel or motor drives the lead screw, converting rotational motion into linear vertical movement of the grinding wheel head or workpiece table. It may include vernier scales, digital readouts, or CNC controls for precise positioning. The mechanism is designed to handle vertical travel ranges from 200 to 600 mm, with feed rates adjustable from 0.01 to 5 mm/min. Positioning accuracy is ±0.005 mm, and repeatability is ±0.002 mm, both referenced to ISO 230-2. Maximum load capacity, including workpiece and fixture, ranges from 500 to 2000 kg. Motor power is typically 0.75 to 5.5 kW, with supply voltage of 380–480 V AC (3-phase, 50/60 Hz) per IEC 60038. Operating temperature range is 5–40 °C, and ingress protection is IP54–IP65 per IEC 60529. The guideway type is linear roller, providing high rigidity and low friction. Screw lead ranges from 5 to 20 mm, affecting resolution and speed. Net weight is 150–800 kg. Materials commonly used include alloy steel, cast iron, and bronze. These specifications are typical ranges; actual values must be confirmed with the manufacturer for specific models and applications. Standards listed are for reference and verification, not certification. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The vertical feed mechanism operates by converting rotational motion from a handwheel or motor into linear vertical movement via a lead screw and nut assembly. The lead screw is rotated, causing the nut to move along its axis, which in turn moves the grinding wheel head or workpiece table vertically. Precision guides ensure straight and smooth motion. The mechanism may incorporate vernier scales, digital readouts, or CNC controls for accurate positioning. Feed rate and depth of cut are adjusted by controlling the rotation speed and angle. The system is designed to provide high rigidity and low friction, enabling precise and repeatable positioning for surface grinding operations.
