Product Description

Product Description

Vertical Center Hole Grinding Machine

The 2M8015, 2M8018 series center hole grinding machine stands as a testament to the innovative fusion of domestic and international technology since its inception in 1967. This exceptional machine is primarily dedicated to grinding the center holes of precision shaft components. It enhances the coaxial alignment of center holes at both ends and refines the roundness, angle, and surface finesse of a single center hole, all to elevate the roughness quality during external grinding processes.

This machine epitomizes versatility and precision, making it ideal for applications involving cutting tools, spindles, tool holders, gear shafts, and tempered transmission shafts. It is specifically engineered for workpieces that demand high accuracy in cylindrical grinding, as the quality of the cylindrical grind is intricately linked to the geometrical accuracy of the center hole's circular design.

Product advantages

1. The grinding head's upward and downward movement is supported by a robust double V guideway structure, while the tailstock's movement relies on a durable dovetail guideway structure, ensuring the machine tool's exceptional rigidity and stability. 2. Every guideway and contact surface is meticulously scraped and hand-finished, highlighting our commitment to craftsmanship. 3. The grinding head spindle incorporates an imported high-frequency electric spindle, offering seamless, infinite speed adjustments from 0 to an impressive 60,000rpm via the frequency converter. 4. The grinding head body allows for both manual and automatic feeding, catering to diverse operational needs. 5. For precision, the diamond pen can traverse the grinding wheel cone surface linearly, and simultaneously, perform lateral back-and-forth vibrations, independent of its wear and positioning. 6. The workpiece clamping utilizes an automatic centering clamping device, simplifying installation and adjustment processes, enhancing operational efficiency.

The Semi-Automatic PET Bottle Blowing Machine is an advanced solution for producing PET plastic containers and bottles of all shapes. It efficiently caters to the manufacturing needs of diverse industries, delivering precision and scalability.
