Drilling Machines

Designed to perform complex machining on industrial components and cylinders, deep hole drilling lathes ensure high performance and efficiency. They are used in the paper and mechanical industries.

Drill Matic series

All structural components are made of high-quality cast iron, giving the structure both weight and rigidity. The machine features a dual-bed configuration to eliminate any interference between the drilling headstock carriage and the dividing head, tailstock, or any steady rests.

This type of machine tool is equipped with a customizable number of drilling heads, usually between 140 and 240, connected by a gear transmission system that enables simultaneous machining along the required length of the workpiece. The minimum distance between two adjacent drilling heads is 35.712 mm, which can be increased according to specific operational requirements.
