The material of linear boring machine mainly includes high-strength cast iron. Specifically, high-strength cast iron HT200-300 is a commonly used material, and its working surface hardness is between HB170-240. After two manual treatments (such as artificial annealing at 600-700 degrees or natural aging for 2-3 years), Ez az anyag stabil pontossággal és jó kopásállósággal rendelkezik .
In addition, the accuracy standard of linear boring machine is also worth mentioning. Its flatness standard is the national level 3 standard, and the T-slot straightness standard is twice the national level 2 standard. Flatness can be detected with a combined level, and the straightness of the T-slot can be detected with a light tube collimator.
