In deep-hole drilling, small-diameter holes of less than 1 mm are machined using carbide gun drills, whereas holes of 15 mm and above are typically drilled using welded-edge drills, and holes of 25 mm and above are drilled efficiently using indexable-insert drills.

In the modern manufacturing industry, with the product complexity and accuracy requirements continue to improve, the traditional single processing method has been difficult to meet the production requirements. jp46-500 precision turning and milling machine should be the

Versatility: Turning and milling compound lathe can carry out turning, milling, drilling, tapping and other machining operations, which reduces the number of workpiece clamping and machining time. As an advanced processing equipment, mill-turning lathe is characterised by its versatility, high precision and high efficiency.
