“What sets us apart from our competitors is our ability to manufacture everything internally,” says Jim Hower, engineer at Technical Processing and Engineering Inc. (TPEI). The Lehighton, Pennsylvania, manufacturer provides spare parts for continuous mixers and extruders, designs and manufactures compounding equipment, and repairs and rebuilds equipment for the plastics and rubber industries. For years, TPEI serviced its customers’ smaller mixers, but it did not have the equipment necessary to rebuild their larger equipment.

“The investment in the machine tools required to be able to repair or rebuild those larger units was pretty significant,” Hower says. “But we got to the point where we felt there was enough of a market to justify that investment.”

TPEI determined it needed to upgrade its manual lathe from a 160-inch bed with a 32-inch swing to a lathe with a bed length of approximately 200 inches in order to machine some of the components for those larger mixers and extruders. The company ultimately decided the Romi C 830 CNC lathe was the best solution for its needs.

Romi has introduced a line of hybrid machine tools that combine traditional machining operations with 3D metallic additive manufacturing.

Three Generation D vertical machining centers—the D 800, D 1000, and D 1250—form the basis for this family of hybrids. They feature heavy cast bases; roller guides on all axes; direct-drive spindles; and have a maximum machining volume of 31 by 24 by 25 in., 40 by 24 by 25 in., and 50 by 24 by 25 in., respectively.

Switching to AM operation involves swapping out a tool with the machine’s 3D printing head. An automatic toolchanger brings the head into position then the laser-deposition-AM process begins. Material can be added to the workpiece in the exact profile, amount, and location desired, reports the manufacturer.

The machines are recommended for part repair, adding features, and intricate work in which subtractive manufacturing would consume too much time and material.

Romi teamed with Hybrid Manufacturing Technologies—developer of the Ambit additive head—to design the hybrids.

Additive and subtractive manufacturing in a single machine

Romi has introduced a complete line of hybrid manufacturing machine tools that combine traditional machining operations with metal additive manufacturing. The new machine is ideal for part repair, adding features, or intricate work where subtractive manufacturing would take more time and produce more waste material.

This new generation of D Series vertical machining centres are the basis for this family of hybrids and include the D 800, the D 1000 and the D 1250. The three models have a robust and heavy casting, roller guides on all axes, big plus direct-drive spindle and a maximum machining volume of 31 x 24 x 25 inches, 40 x 24 x 25 inches and 50 x 24 x 25 inches, respectively. Also available as a hybrid is the Romi DCM 620-5X five axes vertical machining centre.

Romi has made switching back and forth from subtractive machining to additive manufacturing as simple as making a tool change. An automatic tool changer brings the additive head into position, which allows the laser deposition – additive process on the workpiece to begin. The tool changer allows fresh material to be added to the piece in the exact profile, amount and location desired.

Romi teamed with Hybrid Manufacturing Technologies, led by Dr. Jason Jones to make the D Series Hybrids a reality. Hybrid Manufacturing Technologies makes over ten AMBIT FLEX processing heads for the hybrid D series machines. The versatility of these processing heads provides unmatched operational flexibility for a variety of applications, including machining with additive manufacturing (metal, polymer, or composites) and inspection (surface and subsurface). Dr. Jones is the pioneer and world’s leading authority on hybrid manufacturing – integrating Additive Manufacturing (AM) with mainstream CNC machines. He is the co-founder and CEO of Hybrid Manufacturing Technologies.

According to Mr. Rafael Boldorini, General Manager at Romi USA, “While we didn’t invent additive manufacturing, we have made it more accessible for smaller shops with our standard line of Hybrid CNCs. Previously, customers had to spend well over $1,000,000.00 to take advantage of these capabilities. By building our D Series specifically for hybrid manufacturing, we can offer an entry-level machine starting at a much more affordable price point. That has opened the door for a lot of shops to take advantage of this powerful technology.”

The D-Series are equipped with thermal compensation monitored with sensors to improve precision. Each model is equipped with a Fanuc 0i-MF i-HMI CNC with a 15-inch touchscreen, and a high-speed and high-quality package that allows better performance during machining.

Designed and built based on extensive customer research, the New Generation Romi D Series vertical machining centers offer users higher productivity, robustness, and precision. Like all Romi machine tools, they are built with Romi made mono-block cast iron beds that absorb vibration and allow consistent precision production of parts.

Romi has introduced the New Generation GL Series 2-Axis horizontal turning centers. The new machines are available in four models with maximum cutting diameters ranging from 11″ (282mm) to 19.3″ (490mm) and Z travel ranging from 23.6″ (600mm) to 47.2″ (1,200mm). Designed for medium to high production environments, the GL Series features notably high power, torque, and feed force, in addition to Romi’s trademark rigidity and precision attributed to the robust Romi-made monoblock base.

Models include the GL250, GL300, GL350, and GL450. Each is constructed with durable roller ways on all axis to produce high rigidity. A built-in spindle motor with a chiller incorporated and direct-drive servomotors results in high response speed, accuracy, less vibration, and lower maintenance requirements. Chilling the motor increases life expectancy and produces less thermal expansion.

The all new GL Series come standard with active thermal compensation to maintain consistent accuracy even as the machine temperature increases over the course of extended use. The tailstock is programmable and servo driven. Position, speed, and force are determined directly via the Fanuc controller that reduces setup time.

Each model comes with a 12-station turret with a choice of fixed tools with a Romi disk, driven tools with a VDI or BMT disk, driven tools with Y-axis, or dual spindle with driven tools and Y-axis.

The CNC control features a Fanuc Oi-TF with 15″ LCD touchscreen and Fanuc 32iB with 19″ LCD touchscreen for dual spindle version machines and is the newest generation of Fanuc’s Series iHMI. It is designed to produce faster, more accurate performance for turning applications with separate areas on the main screen for planning, machining, improvements, and utilities. Functions are accessible with just two clicks. It comes standard with an ethernet interface, as well as a compact flash card and USB ports.

Romi’s GL Series turning centers are all produced in Romi’s state-of-the-art facilities that maintain various safety and quality certifications including ISO 9001, ISO 14001, IATF 16949, and CE.

“Designed and built based on extensive customer research, the new generation Romi D Series vertical machining centers (VMCs) offer users higher productivity, robustness and precision. Like all Romi machine tools, they are built with Romi made monoblock cast iron beds that absorb vibration and allow consistent production of highly precise parts,” said a company spokesperson.

In the USA, Romi offers three models, the D 800, the D 1000 and the D 1250. All three are equipped with big-bore 40-taper direct drive spindles with speeds of 10,000 RPM or 15,000 RPM. “Direct drive is low maintenance and improves accuracy and repeatability, while the big-bore 40-taper increases stiffness and allows increased depth of cut during machining,” said the spokesperson.

The machines are equipped with thermal compensation with sensors to improve precision. Each model is equipped with a FANUC 0i-MF i-HMI CNC with 15″ touchscreen, and a high speed and high quality package that allows better performance during machining.

“Linear roller guides on all three models facilitate feedrates up to 1,575 IPM (40 m/min), which allows for precise and fast acceleration and positioning. They also increase robustness during machining and load capacity (part weight) on the table,” said the spokesperson.

The three models, D 800, D 1000 and D 1250, have a net machine weight of 20,500 lbs., 21,800 lbs. and 23,000 lbs. and a maximum machining volume of 31″ x 24″ x 25″, 40″ x 24″ x 25″ and 50″ x 24″ x 25″. Each model is equipped with a 30 tool automatic vertical tool changer.
