D Series Hybrid Machining Centers Throw Additive Into the Mix

Jan. 26, 2021

Romi has introduced a complete line of hybrid manufacturing machine tools that combine traditional machining operations with 3D metallic additive manufacturing. The Generation D Series vertical machining centers are the basis for this family of hybrids and include the D 800, the D 1000, and the D 1250. The three models have heavy casting, roller guides on all axes, big plus direct-drive spindle, and a maximum machining volume of 31 x 24 x 25 in., 40 x 24 x 25 in., and 50 x 24 x 25 in. respectively.


Romi has made switching back and forth from subtractive machining to additive manufacturing as simple as making a tool change. The additive head is brought into position via an automatic tool changer, and the laser deposition additive process on the workpiece can begin. Material can then be added to the piece in the exact profile, amount, and location desired.


It's ideal for part repair, adding features or intricate work where subtractive manufacturing would take more time, and produce more waste material.


The machines are fitted with thermal compensation monitored with sensors to improve precision. Each model features a Fanuc 0i-MF i-HMI CNC with a 15-in. touchscreen and a high speed and high-quality package that allows better performance during machining. Designed and built based on extensive customer research, the D Series offer users higher productivity and precision.

  • Materials can be added in the exact amount to achieve the desired profile, and later machined
  • Savings in the use of high-cost materials
  • Low-temperature transmission to the part, avoiding possible thermal cracks
  • Performs engraving and texturing operations
