Doosan Machine Tools announces the addition of the DNM 4000 to its line of vertical machining centers. This compact VMC was designed for lean cell applications where space is tight, but productivity and cutting performance are essential.

Able to take more aggressive cuts than similarly sized 30 taper drill – tap machines, the DNM 4000 is suitable for machining small parts in tough-to machine materials for a range of industries including medical, aerospace, automotive, job shops, firearms and die and mold. Featuring a 12,000-rpm, 25-hp, 40-taper spindle with 86 ft.-lbs. of torque and a standard BIG-PLUS dual-contact interface, the DNM 4000 delivers short cycle times, fine part surface finishes and long tool life.

This vertical machining center has a compact footprint of only 65"W x 112"L x 108"H and travels of 20.5" in X, 15.7" in Y and 18.9" in Z. The two-door design reportedly incorporates the largest opening width in its class, allowing for easy operator access. The coolant system is located in the rear of the machine so the DNM can be placed mere inches from the neighboring machines.

The DNM 4000 comes with a long list of standard features. These include a 20-tool capacity magazine with a 1.3-second tool-to-tool time, standard spindle cooler, Doosan Smart Thermal Monitoring software, grease lubrication system and 230-psi through-spindle coolant. The FANUC i control with Easy Operation Package (EOP) software developed by Doosan provides numerous functions designed for convenient operation and reduced setup time.

"The DNM 4000 was purposefully developed to be small in size, but not in power," said Andy McNamara, director of sales at Doosan Machine Tools America. "Manufacturers can now enjoy increased productivity and performance without sacrificing compactness."
