Machine tool usage:
♦ It can achieve precision honing machining of large bore inner holes in ship low-speed diesel engine cylinder liners, large hydraulic cylinders, mining and petroleum machinery parts, and similar parts.
♦ Can process materials such as cast iron, carbon steel, non-ferrous metals, hard alloys, ceramics, etc.
Processing accuracy:
◆ Dimensional accuracy IT6 level, surface roughness Ra0.4 or above.
Especially suitable for:
Specialized batch processing of cylinder liner inner hole honing for low-speed diesel engines (including G series) with cylinder diameters below 800mm (including 800mm) designed by MD company, and cylinder diameters below 800mm (including 800mm) designed by W Ä RTSIL Ä company, as well as PA and PC medium speed diesel engines.
The maximum processed workpiece is:
The outer diameter, inner diameter, and length are both 1200 mm, 800 mm, and 4000mm respectively, with a weight of less than 9.0 tons.
