Line boring is a very convoluted thing and therefore, the staff takes no chance at all and simply relies upon the best machines. The best machines are determined on the basis of various factors and the most crucial of them all is the boring diameter.
According to the experts, a machine can be called an ideal, if it is capable of supporting boring diameters from 1.375 to 80 inches (35 to 2030 mm approx). Other factors that are determined at the time of selection of the machine are –
• The speed of the machine
• How precisely it is generating the results
Apart from these, some features are also looked for like specially designed mounting brackets, spherical bearings, self-centering set-up cones, and movable rotational drive and feed units. They are expected to be there in the machine, as they all simplify the set-up and allow the machine to work in conditions too tight for different machines used in this task. Moreover, the basic as well as highly advanced models should equally feature –
• Rugged Rotational Drive
• Axial Feed Systems
• Precision Bars
• Heavy Duty Bearings
• Electric, Pneumatic And Hydraulic Options
All of them should have the ability to work on the same mounting system with Auto Bore Welding Systems for single-setup machining and welding. Based on the features discussed above, we have got three different line boring machines that are unarguably the best. Let us know some more facts and figures about them.
