Product Description

Product Description

Vertical Center Hole Grinding Machine

The The 2M8015 and 2M8018 series center hole grinding machines, designed with insights from both domestic and international technologies since 1967, excel in precision. These machines are primarily utilized for grinding the center holes of various precision shaft components. They enhance the coaxiality and improve the roundness, angle, and surface roughness of a single center hole, ensuring exceptional outer grinding surface finish.

Ideal for cutting tools, spindles, tool holders, gear shafts, and hardened transmission shafts, this machine meets high-accuracy cylindrical grinding requirements. The excellence of cylindrical grinding hinges on the circular geometrical precision of the center hole.

Product Advantages

1. The grinding head's vertical guiding mechanism boasts a double V structure, while the tailstock features a dovetail guideway, ensuring exceptional rigidity and machine stability. 2. All guiding and contact surfaces are meticulously hand-scraped for precision engineering. 3. The grinding head spindle is equipped with an imported high-frequency electric spindle, offering infinitely variable speeds up to 60,000 rpm via a frequency converter. 4. The grinding head's vertical feed can be operated manually or automatically for better control. 5. When dressing the grinding wheel, the diamond pen can traverse the grinding wheel cone surface in a straight line while accommodating lateral vibration, ensuring precision independent of wear and positioning. 6. Automatic centering clamping devices simplify workpiece installation, enhancing operational efficiency.

This Semi-Automatic PET Bottle Blowing Machine is expertly designed for crafting PET plastic containers and bottles of various shapes and sizes.
