Product Description

Product Description

Vertical Center Hole Grinding Machine

The The 2M8015, 2M8018 series center hole grinding machine was ingeniously crafted in 1967, drawing inspiration from top-tier machine tools worldwide. This machine is meticulously engineered for the precision grinding of center holes in various shaft parts. It enhances the coaxiality of center holes at both ends, improving roundness, angle, and roughness, ultimately ensuring superior outer grinding roughness.

This versatile machine excels in applications involving cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts, where high precision in cylindrical grinding is paramount. The machine's effectiveness largely hinges on the circular geometric accuracy of the center holes.

Product Advantages

1. The grinding head's upward and downward movement guideway features a double V structure, complemented by a dovetail guideway structure for the tailstock, ensuring exceptional rigidity and stability. 2. Each guideway surface and contact point is painstakingly scraped and manually finished for optimal performance. 3. The grinding head's spindle is equipped with an imported high-frequency electric spindle, allowing infinite speed adjustments from 0 to 60,000rpm via a frequency converter. 4. The grinding head body supports both manual and automatic feeding for versatile operation. 5. The diamond pen, when dressing the grinding wheel, can precisely move along the grinding wheel's cone surface in a straight line, also enabling lateral back-and-forth oscillation, maintaining independence from the diamond pen's position and wear impact. 6. Workpiece clamping is streamlined through an automatic centering clamping device, simplifying installation and adjustment.

The Semi-Automatic PET Bottle Blowing Machine efficiently produces PET plastic containers and bottles in all conceivable shapes, offering unparalleled flexibility and reliability.
