Our DeHoff machines feature a robust high-pressure coolant system, a PC-based control system, and various fixturing options to suit your needs. These machine systems are designed, engineered, and manufactured in-house for unsurpassed performance and reliability.
DeHoff high-pressure coolant systems are extremely robust and can handle either oil or water-soluble coolants. The coolant tank has a capacity of up to 500 gallons (1893 L), and features a twin tank system with a separate clean tank and dirty tank.
The coolant system features an optional chip conveyor to separate the larger metal chips from the cutting fluid. Chip conveyors are available as either magnetic or flighted type, and 6 or 12 inches (152 or 305 mm) wide. The system also has twin filter canisters for additional filtration, which are equipped with pressure switches to indicate clogged filters.
The temperature of the cutting fluid is controlled by a shell-and-tube heat exchanger, which can use water from the facility or Glycol from an external chiller unit. Coolant system parameters such as flow, temperature, and pressure can be monitored and adjusted from the machine control panel.
DeHoff machines use an embedded PC-based controls system featuring Beckhoff Controls. This system emulates the typical PLC-based control while also providing features commonly associated with a PC.
Beckhoff Controls use the Microsoft Windows® OS with built-in Ethernet capability. The system utilizes a solid-state disk drive instead of a typical PC magnetic hard drive. This results in no moving parts and increased reliability in a production environment.
The control system also features a robust EtherCat communication technology for high-speed interface with the machine spindle and servo drive, resulting in dynamic performance of the servo system.
The Beckhoff Controls package is also available for control retrofits, either as a field installation or as part of a full factory machine rebuild.
DeHoff machines offer various workpiece handling options to accommodate the different lengths and diameters of customer parts.
Available on the DeHoff 20 Series, the High-Torque Gearbox enables the operator to change the spindle torque with the pull of a lever, instead of a time-consuming belt and pulley changeover. It is also able to deliver up to twice the torque of a standard duty machine. The High-Torque Gearbox is ideal for the drilling of high temperature material where low surface speeds are required, yet high torque at the spindle is also necessary.
Included in the option is a 4-speed transmission gearbox, manual change with proximity sensors for range display, heavy duty spindle assembly and pulleys, belts, and 2:1 feed drive gearbox for increased feed thrust. No spindle pulley change is needed.
