Product Description

Product Description

Vertical Center Hole Grinding Machine

The The 2M8015 and 2M8018 series center hole grinding machines, inspired by both domestic and international designs since 1967, have been meticulously researched and crafted. Primarily catering to the precision grinding of center holes in various shaft parts, this machine significantly enhances the coaxial alignment of center holes on either end. It perfects the roundness, angular precision, and surface finish of individual center holes, thereby guaranteeing superior outer grinding surface quality.

This advanced machine is perfectly engineered for components such as cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts, where high accuracy in cylindrical grinding is paramount. The excellence of cylindrical grinding is intrinsically linked to the precise geometrical accuracy of the center hole.

Product Advantages

1. The innovative grinding head features an upward and downward moving guideway with a double V structure, while the tailstock is equipped with a dovetail guideway, ensuring exceptional machine rigidity and stability. 2. All guideway and contact surfaces undergo meticulous manual scraping and research for enhanced 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. Grinding head body offers both manual and automatic feeding options for versatile usage. 5. During grinding wheel dressing, the diamond pen can trace the grinding wheel's cone surface linearly, coupled with lateral back-and-forth vibration, independent of wear and pen positioning. 6. Workpiece clamping is simplified with an automatic centering clamping device, streamlining installation and adjustment processes.

The Semi-Automatic PET Bottle Blowing Machine excels in crafting PET plastic containers and bottles of diverse shapes. It stands out as a pinnacle in bottle making, molding, and manufacturing.
