The DeHoff 3060 is a single-axis boring machine used in the railroad manufacturing supply chain. The machine is custom designed for boring the bottom housing of a rail car hopper bin.
The DeHoff 3060 has a single spindle with a maximum boring capacity of 3 inches (76.2 mm) and a maximum boring depth of 60 inches (1524 mm). To meet the rigorous material removal requirements, the cutting tool is powered by a 40 horsepower spindle motor with a 4-speed gearbox. A totally custom workpiece loading and fixturing system was designed specifically for the customer’s unique part. The machine features Beckhoff CNC controls with G-Code programming capability.
DeHoff machines feature steel box ways and hand-scraped mating components (instead of cheaper linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved surface finish. DeHoff deep hole drilling and boring machines are designed and manufactured by Kays Engineering in Marshall, Missouri, USA.

- G-code programming
G-code programming
Programs written to operate NC machines with control systems that comply with the ANSI/EIA RS-274-D-1980 Standard. A program consists of a series of data blocks, each of which is treated as a unit by the controller and contains enough information for a complete command to be carried out by the machine.
- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- boring machine
boring machine
Similar to a turning machine except that the cutting tool (single-point or multiple-cutting-edge), rather than the workpiece, rotates to perform internal cuts. However, boring can be accomplished by holding the tool stationary and turning the workpiece. Takes a variety of vertical, slanted and horizontal forms, and has one or more spindles. Typically a large, powerful machine, it can readily hold tolerances to 0.0001". See jig boring; lathe; turning machine.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
