AT320 Milling and Turning Machine

CORMAK Tokarko-frezarka CORMAK AT320

CORMAK AT320 is a professional combination lathe and vertical milling machine designed for precision metalworking in manufacturing facilities, toolrooms, maintenance workshops, and repair shops. By integrating both a lathe and a milling machine into a single compact unit, the operator can perform complex machining operations without removing or repositioning the workpiece, significantly improving accuracy and productivity. The machine is supplied with a complete set of 16 × 16 mm turning tools and an MT3 live center.

Key Features
2-in-1 machine – combines a universal lathe and a vertical milling machine in one compact, heavy-duty design.
Separate induction motors for the lathe and milling machine provide maximum torque and independent operation.
38 mm spindle bore allows machining of larger-diameter shafts and bar stock.
Hardened and precision-ground guideways together with a hardened gearbox ensure long service life and high machining accuracy.
Thread cutting without changing change gears enables fast setup for different threading operations.
Vertical milling head with ±90° tilt and 360° column rotation provides exceptional flexibility for angular and multi-sided machining.
Integrated coolant system supplied as standard extends cutting tool life and improves machining performance.
Construction and Technology

The CORMAK AT320 is built on a rigid cast iron bed with induction-hardened and precision-ground guideways, ensuring excellent accuracy even during long carriage movements.

The 1.5 kW lathe motor provides reliable performance when machining a wide range of materials, including carbon steel, stainless steel, aluminum, and brass.

The vertical milling head is mounted on a round column, allowing 360° rotation and ±90° head tilt, greatly expanding the range of possible machining operations.

Precision and Productivity

The machine is capable of accurate longitudinal, cross, and taper turning, as well as metric and imperial thread cutting.

The 12-speed lathe gearbox and 4-speed milling gearbox allow optimal selection of cutting parameters for various materials and machining operations.
