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 — such as 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 pounds 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 touchscreen 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.

Improving American productivity for more than 80 years, Zagar Inc. manufactures and distributes, multi-spindle drill and tap heads and machines a range of workholding solutions, feed units, robotic end effectors, and offers a range of contract manufacturing services. The company’s expertise is machining both ferrous and non-ferrous materials for industries such as automotive, aerospace, electrical, medical, off-road construction equipment, hydraulic, pneumatic, and high-production drilling and tapping.
