Electric Cylindrical Grinding Machine

The Electric Cylindrical Grinding Machine is a dedicated industrial system engineered by National Cutting Tools for <p>The Electric Cylindrical Grinding Machine by National Cutting Tools is a high-precision grinding machine tool designed for external cylindrical grinding on shafts, precision pins, spindle blanks, and motor rotors. Turning operations on lathes leave tool marks and minor diameter variations; cylindrical grinding removes microscopic amounts of material to achieve mirror surface finishes (Ra 0.2 to 0.4 µm) and strict geometric tolerances within 0.002 mm.</p>.

<p>Built with a heavy cast-iron base that dampens wheel harmonics, the machine features a precision wheelhead driven by an electric motor, an adjustable workhead with variable speed control, and a smooth table traverse driven mechanically or hydraulically. Precision hydrodynamic or preloaded angular contact spindle bearings ensure vibration-free wheel rotation for superior roundness and cylindricity on hardened steel parts.</p>

<h3>Key Features</h3>

<ul>

<li><strong>Micron-Precision Wheelhead Spindle:</strong> Hardened alloy spindle rotating in precision hydrodynamic bearings delivers chatter-free grinding.</li>

<li><strong>Variable Speed Workhead:</strong> Regulates workpiece rotational speed to match workpiece diameter and grinding wheel grit specifications.</li>

<li><strong>Heavy Cast-Iron Base:</strong> Normalized graded casting provides massive thermal stability and absorbs wheel-balancing vibrations.</li>

<li><strong>Fine Infeed Micrometer Dial:</strong> Allows precision micro-infeed adjustments down to 0.001 mm for tight tolerance production.</li>

<li><strong>Swiveling Table for Taper Grinding:</strong> Graduated table swivels to allow precision taper grinding on tool shanks and machine tapers.</li>

<li><strong>High-Efficiency Coolant with Magnetic Separator:</strong> Keeps the grinding zone cool and removes metal swarf and abrasive grit from the fluid.</li>

</ul>

<h3>Applications</h3>
