Product Description

Product Description

Vertical Center Hole Grinding Machine

The 2M8015, 2M8018 series center hole grinding machine is the absorption of the same type of machine tools at home and abroad in 1967 on the basis of research and design, mainly used for various precision shaft parts of the center hole grinding. Improve the coaxiality of the center holes at both ends and the roundness, Angle and roughness of a single center hole to ensure the roughness of the outer grinding.

The machine is suitable for cuttingtool, spindle, tool holder, gear shafts and tempered transmission shafts and the workpiece requestshigh accuracy from cylindrical grinding. The quality of cylindricalgrinding will depend on the centerhole circular geometrical accuracy.

Product advantages

1. The upward and downward moving guideway of the grinding head adopts double V structure, and the upward and downward moving guideway of the tailstock adopts dovetail guideway structure, which ensures the high rigidity and stability of the machine tool. 2. All guideway surfaces and contact surfaces are scraped and researched manually. 3. The spindle of the grinding head adopts imported high-frequency electric spindle, and the speed can be infinitely adjusted from 0 to 60,000rpm through the frequency converter. 4. The upper and lower feeding of the grinding head body can be fed manually or automatically. 5. When dressing the grinding wheel, the diamond pen can move along the grinding wheel cone surface in a straight line, but also at the same time, lateral back and forth vibration. Completely independent of the position of the diamond pen and the impact of wear. 6. The workpiece clamping adopts automatic centering clamping device to simplify the installation and adjustment of the workpiece.

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
