Product Description

Product Description

Vertical Center Hole Grinding Machine

The The 2M8015 and 2M8018 series center hole grinding machines are expertly crafted, drawing inspiration from domestic and international counterparts since 1967. They are specifically designed for precision shaft parts' center hole grinding, enhancing both ends' coaxiality and a single center hole's roundness, angle, and surface smoothness. This ensures that the external grinding surface retains its superior finish.

This machine is ideal for a variety of high-precision components such as cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts. Its performance is pivotal for applications demanding impeccable cylindrical grinding accuracy, which is largely dependent on the geometrical precision of the center hole.

Product Advantages

1. The grinding head's vertical movement is supported by a dual V guideway, while the tailstock's employs a dovetail design, ensuring unmatched rigidity and stability. 2. Every guideway and contact surface is meticulously hand-scraped and examined for precision. 3. Equipped with an imported high-frequency electric spindle, the grinding head offers variable speeds ranging from 0 to a remarkable 60,000rpm via a frequency converter. 4. The grinding head body can be manually or automatically adjusted for feed. 5. The diamond pen, during wheel dressing, can traverse the cone surface straight, with additional lateral oscillation capabilities, unaffected by wear or positioning. 6. Automatic centering device for workpiece clamping simplifies installation and adjustment, streamlining operations.

The Semi-Automatic PET Bottle Blowing Machine is a versatile solution for creating PET plastic containers and bottles of various shapes, perfect for diverse production needs.
