WR2 160 / WR2 200

Product catalog summary

Overview: The WR2 160 and WR2 200 are horizontal deep drilling machines designed for specialized deep hole drilling processes. They are equipped with advanced CNC systems for precise and efficient machining.

Basic Parameters: The machines offer a maximum spindle torque of 50,000 Nm, can handle workpieces up to 40 tonnes, and drill holes up to 10,000 mm in length and 800 mm in diameter.

Main Features: Key features include a 2-guideway bed made from enhanced cast iron, hardened guideways, a central lubrication system, and a tool liquid cooling system with a 10,000-liter tank. The machines also have a range of continuously variable spindle rotation rates from 0.5 to 315 rpm.

Standard Execution: The WR2 160 has a swing over bed of Ø1,600 mm, while the WR2 200 offers Ø2,000 mm as an optional feature. Both models have a main drive motor power of 75 kW and are equipped with a rack-and-pinion transmission for Z-axis travel.

Optional Execution: Options include a drilling tailstock with a live tool, steel guideways hardened up to 56 HRC, and other custom arrangements.

Additional Equipment: Various steady rests are available, ranging from Ø100 to Ø1,600 mm, to support different workpiece sizes.

Technical Specifications: The machines support a range of drilled hole diameters from Ø30 to Ø800 mm, with a maximum axial force of 100,000 N. The overall dimensions vary with the drilling length, with a base weight of 30,000 kg for a 3,000 mm drilling length.
