PAINT BOOTH INVESTMENT: PRECISION PAINTING FOR UNISIG MACHINES

Paint Booth interior

UNISIG machines are designed to run for 20 years or more in production. While operating, the machines are exposed to factory conditions that are not ideal for precision machinery. Cutting fluid—whether straight oil or water-soluble—contains extreme pressure (EP) additives that improve tool performance but can degrade or damage seals and paint on the machines over time. We want our machines to look good while they age. Part of our strategy for this is to use a two-component polyurethane enamel to paint our base castings, structural frames, machine enclosures, or any fabricated metal parts in our machines. Recently, we targeted our painting department for investment to keep up with our growing company and expanding product line. Our goals for investment were clear:

  • Improve the shop environment in the painting area
  • Improve the quality of the finished product
  • Increase the dimension of parts we could paint
  • Reduce the amount of paint used and wasted
  • Increase the productivity in painting
  • Increase the throughput in the paint department

Manufacturing engineers researched the technology available, and as in most cases in manufacturing, we were even more excited about the project after learning what was possible.

DIMENSIONS AND INTERIOR

The paint booth’s workspace measures 16 feet wide by 30 feet deep, allowing us to paint large single components—such as machine bases and columns—or groups of smaller enclosure parts.

To handle large workpieces efficiently, the booth features a crane access slot in the roof that automatically opens for a bridge crane to place components, then closes and seals for painting.

Bright, well-planned lighting ensures clear visibility during painting and inspection, supported by targeted task lighting for detail work. Floors and walls are maintained regularly to preserve brightness and the overall quality of the painting environment.

“It’s an investment in long-term quality, efficiency, and the appearance of every UNISIG machine that leaves our facility.”

AIR HANDLING AND PAINT MIXING

Once the basic dimensions and working areas were defined, we specified a makeup air unit that draws in fresh air, filters it, and exhausts it to the outside. The system also heats and conditions the air to maintain optimal painting temperatures, then provides a curing cycle that raises the booth temperature for an hour after painting before rapidly cooling the parts. The air handling aspect of this project improved our throughput significantly because we can handle the painted items soon after painting. It also eliminated any odors from curing, which improved the working environment in and around the painting department.

The high-tech enamel applied to UNISIG machines is not cheap, and the formulation of the two parts must be carefully measured, or the result will not be consistent. UNISIG manufacturing engineers added an automatic mixing system to the project to precisely meter the individual components near the painting gun. This assures the exact mix is used, but also drastically reduces wasted paint. Our painting technicians have bulk color components in different pots, and choosing the paint color is as simple as pressing a button on the touch screen. Solvent for cleaning the gun or prepping the workpieces is also available as a selection on the control.

TRAINING, MAINTENANCE, AND CONTINUOUS IMPROVEMENT

The final step was training our team on the new technology and changing the expectations of what was possible. A regular maintenance schedule is followed, and paint quality is constantly evaluated as we continue to improve our painting performance. This investment represents more than a new paint booth—it’s an investment in long-term quality, efficiency, and the appearance of every UNISIG machine that leaves our facility.

WHAT DOES IT MEAN TO BUILD AUTOMATION?

Automation Gundrilling Cell

Automation is part of our DNA at UNISIG. Many of our deep hole drilling machine projects include some level of automation, and we think about it at every step of development. This approach allows us to offer customers automation options with their initial purchase or as a future upgrade, ensuring their investment is compatible with automated production.

UNISIG machines are servo-driven and equipped with programmable feed rates, positions, and spindle speeds that optimize production. Many models also include servo-driven workpiece positioning systems that automatically prepare the machine for the next part. The user interface clearly shows the machine’s position and cycle status, making it simple for operators to complete one cycle and start the next.

Before automating a machine, the drilling operation itself must be stable and controlled. UNISIG’s process monitoring system tracks drilling conditions in real time and can automatically adjust parameters to maintain cycle performance. When limits are reached, the machine interrupts operation to protect the tool and workpiece while communicating what fault caused the stoppage. This feedback helps operators fine-tune parameters for successful drilling and establish tool life settings for high-volume production.

INTEGRATED AUTOMATION: BUILT FOR EFFICIENCY

Not every automated system requires a robot moving parts around. In-machine automation, such as smart conveyors, indexing pallets, and bulk feeders, can provide fully automated operation within a compact footprint. These integrated systems are often designed to ship with the machine as a single unit, ready for production.

UNISIG also offers “robot-ready” machines. Depending on the model, this can include communication protocols, automatic doors, powered fixturing, and presence sensors. These features simplify future robot integration while making manual operation more efficient for the operator.

“Automation is never an afterthought. It is built in from the very beginning.”

UNISIG designs and builds deep hole drilling machines and automation systems. We provide the latest tools, equipment, and technology so our skilled team can take pride in their work and enjoy producing high-precision machines. One of those tools is our hand-held laser welder. We fabricate machine enclosures and other components that require long, watertight, clean welds. Our team of welders has used the latest MIG and TIG welding technologies to deliver high-quality results. When laser welding became viable, we saw its potential, but it took planning and preparation to bring it online. 

Better Welds, Faster

Our Fab Shop Manager evaluated the technology, chose the equipment, and brought one of our welders with him for training. Safety is a priority at UNISIG. While we waited for delivery, we engineered and built a custom welding enclosure (including the door and electronic interlocks) to exceed safety standards for laser welding and fit perfectly in our space.

We still use MIG for heavy plate and TIG for fine detail work, but the laser welder has proven effective across a wide range of applications. It produces clean, watertight welds across full panels without heat distortion at speeds that seem impossible until you see it in action. These clean welds require minimal finishing, improving workmanship and reducing costs.
