Product Description

Product Description

Vertical Center Hole Grinding Machine

The Introducing the 2M8015, 2M8018 series center hole grinding machines - a marvel in mechanical engineering that draws inspiration from international designs since 1967. Specifically crafted for precision shaft parts, these machines enhance the coaxiality of center holes, refining roundness, angular precision, and surface roughness, ensuring unparalleled performance in outer grinding applications.

Tailored for high-precision applications, this machine is perfect for cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts. It sets the benchmark for cylindrical grinding quality by ensuring the center hole's circular geometrical accuracy is at its peak.

Distinctive Product Features

1. The grinding head's vertical mobility is supported by a robust double V guideway, while the tailstock glides on a dovetail guideway, affirming the machine's supreme rigidity and stability. 2. All guideway and contact surfaces are intricately hand-scraped for optimal performance. 3. The grinding head's spindle, featuring an imported high-frequency electric spindle, boasts a variable speed range up to 60,000rpm, facilitated by a frequency converter. 4. Precision in feeding is ensured with options for manual or automated operation of the grinding head body. 5. The diamond pen dresses the grinding wheel across its conical surface in a linear motion, with the flexibility of lateral vibration, maintaining independence from wear patterns. 6. Workpiece clamping is streamlined via an automatic centering clamping device, simplifying setup and adjustment.

Our Semi-Automatic PET Bottle Blowing Machine is an epitome of innovation, skillfully crafting PET plastic containers and bottles in diverse shapes, meeting a wide spectrum of industry needs with precision and efficiency.
