Z-Mag DTM for Remote Hole Making

Zagar Inc. introduces its Z-Mag DTM™ portable CNC drill and tap machine for remote holemaking operations. The innovation is geared toward industries such as ship building, bridge construction, railroad and several others where metal removal has to be done on location due to structures that are permanently installed or too large to move. Any needed machining - like modifications, retrofitting or for final assembly needs - must be done remotely.

To serve customers with these permanently affixed requirements, Zagar engineered a unique solution that uses an electromagnetic base with 5,000 lbs. of hold-down force, allowing users to bring precision machining to the job site. Z-Mag DTM can be used on any type of ferrous steel for drilling, tapping, reaming and even combination tooling with programmable feeds, speeds, dwells, and peck cycles. Once in position, the operator can safely and ergonomically operate the unit without the need to manually feed by hand.

The unit accommodates different height applications with an available 13 inches of stroke, 1,300 lbf. of thrust and spindle speeds of up to 3,000. Using an HSK style spindle adapter, operators can use a variety of HSK tool holders. The sturdy cast iron frame, linear rail system, and precision ball-screw feed system provide a solid foundation for any application, from light roughing to finishing. With the use of the handheld HMI (Human Machine Interface), the operator can control the unit with touch screen controls and has the capability to program and run all operations. The unit has a servo feed motor for consistent feed rates and precise hole depths. The hold-in-place solution is well suited for carbide cutting tools.

Related Glossary Terms

  • 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.

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • precision machining ( precision measurement)

    precision machining ( precision measurement)

    Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.

  • spindle adapter

    spindle adapter

    Bushing or toolholder that permits affixing a variety of taper- and straight-shank tools to a machine spindle.

  • tap

    tap

    Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.

  • tapping

    tapping

    Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
