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 both domestic and international machine tools since 1967. These machines are primarily designed to be used in the precise grinding of center holes in various shaft parts. They enhance the coaxiality of center holes on both ends, while refining the roundness, angle, and surface roughness of each center hole. This results in superior outer grinding surface quality.

This machine is ideal for applications involving cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts that demand high precision in cylindrical grinding. The perfection of cylindrical grinding is intrinsically linked to the center hole's circular geometric accuracy.

Product Advantages

1. The grinding head's guideway features a robust double V structure, while the tailstock's guideway utilizes a dovetail design, ensuring exceptional rigidity and stability. 2. Each guideway and contact surface undergo meticulous manual scraping and research. 3. The grinding head's spindle employs an imported high-frequency electric spindle, enabling seamless speed adjustments up to 60,000rpm via a frequency converter. 4. The grinding head permits both manual and automatic feeding for upper and lower adjustments. 5. The diamond pen, when dressing the grinding wheel, can traverse the cone surface linearly and laterally, unaffected by its position or wear. 6. An automatic centering clamping device simplifies workpiece installation and alignment.

The Semi-Automatic PET Bottle Blowing Machine, Bottle Making Machine, and Bottle Moulding Machine are ingeniously designed for crafting PET plastic containers and bottles of various shapes with ease.
