Doosan has introduced the DNM 200/5AX compact, reliable and affordable five-axis vertical machining center. This newest member of the DNM Series is ideal for machining complex prismatic parts by reducing set-up time and ensuring consistent accuracy without taking up too much valuable space on the shop floor.
Integrated Trunnion 5-axis Table
The DNM 200/5AX is a purpose built 5-axis machining center, featuring a built in 4th and 5th axis trunnion table allowing for the machining of multiple faces on complex prismatic workpieces, without having to re-fixture.
This unique design provides for more available z-axis clearance than a traditional VMC with a rotary system placed on the standard table. Precision and repeatability are superior as well, due to the reduction in stacked tolerances. The platter size is 7.87" in diameter, allowing for a maximum work piece of 11.81" in diameter and 7.87" in height. The maximum table load is 88 lbs.
Roller Type LM Guideways
As with all Doosan DNM Series vertical machining centers, all linear guideways feature roller type bearings, delivering 3 times more rigidity and double the lifespan. Additional benefits include optimal weight and force distribution, superior stiffness, accuracy, and surface finish.
The direct-coupled spindle drive system is a true cartridge type unit supported by high precision ceramic ball bearings that offer minimal noise, vibration and thermal growth due to the absence of gears or belts inside the spindle head body. The powerful 12,000 rpm, 15 / 25 hp motor has 86 ft-lbs of torque with a spindle accel/decel time of 0 -- 12 k (2.16 sec ) / 12k -- 0 (2.21 sec).
Bed, Column and Saddle Construction
The bed is a rigid, one piece casting made from fine grain Meehanite cast iron with heavy ribbing to help prevent vibration and deformation during heavy cutting. Extra wide spacing of the roller guideways provide for excellent support of the saddle, regardless of the load distribution on the table. The table is fully supported by the saddle in all positions with no overhang. The rigid box type column casting is heavily ribbed to help prevent twisting or distortion as well as helping to dampen vibration during high speed or heavy machining.
