Knuth 20.1HP 20” R 100 Radial Drill Press 101659

Description

The top model of Knuth’s radial drilling machines offers 100 mm (3.9 in) drilling capacity and a huge work area. The stability required for this is achieved through the very heavy design and XL dimensions of all components. Due to the easy handling of large and heavy workpieces and the considerable flexibility due to the long arm, these models are recommended for shipyards, steel, and heavy industry. The R-series has a hydraulically switched gearbox and a multi-plate reversing clutch. Despite the size, it is easy to transport, and assembly takes place on site.

Features

• A large throat and high boring capacities are supported by a very rigid structural design, without compromising the ease of handling and smoothness of operation
• The drill head features a rigid design with motorized or manual movement
• Spindle speeds and feed velocity are hydraulically controlled for easy and safe operation
• The drill spindle is driven via multi-disk reversing clutch to avoid excessive load peaks and for easy operation
• Base, column, boom, and gear head are made of premium high-quality cast
• Boom height adjustment via a powerful motorized drive and vertical spindle
• The boom lifting gears run in an oil-bath for maximum reliability and minimum wear
• Advanced column swivel design with optimized clamping features maximum rigidity and minimum clamping offset
• Swivel axis and travel axis feature extremely smooth operation to make the operator's everyday production work easier
• The gears feature hardened and precision-ground chrome-nickel steel for smooth and low-noise operation
• All gear parts are lubricated reliably via oil pump
• The main spindle runs on precision bearings and features an automatic spindle brake
• Quill teeth are precision-ground for a smooth feed and minimum wear
• The drill head moves on hardened and ground guideways
• Features adjustable overload clutches in the feeds
• Adjustable boring depth stop with large, easy to read scale
• All operator controls are placed within reach for convenient and practical handling and quick learning
• Powerful coolant system with coolant reservoir integrated into the machine foot
• Independent hydraulic clamping of head, column, and boom
