Machine builder makes intricate cuts with Spyral saw blades

Panafab Custom Machine Builders of Suwanee, Georgia has spent three decades advancing the special automation processes of customers ranging from Fortune 500 component and tool makers to small machining companies and even worm breeders.

“We are dedicated to customers looking to augment their production lines with custom equipment and automation systems,” said Joe Panetta, President of Panafab. “After years of investing in the highest quality engineering and programming software, tools and machinery, we now move on to designing and building exclusive lines of industrial automation equipment designed for increase productivity, improve quality and reduce costs in our customer’s manufacturing process.

“However, we still support many of our existing partners with industry-specific solutions designed to enhance their unique production, assembly and manufacturing needs.

In 2013, legacy services expanded to manufacture a custom aluminum handle produced for a hand-held heat sealing tool used by the military to hermetically seal jet engines in sheet polymers. “Unfortunately, our first attempts turned out to be far too expensive for a short run of around a thousand pieces,” Panetta explained. “We tried to create our own extruded profile, but there was no way to cut the handle into the necessary z-pattern with conventional methods. So we decided to think outside the box when we contacted Bestway Products on the advice of one of our associates.

Since 1986, Bestway Products has manufactured a full line of Spyral saw blades that provide tight, intricate cuts that are virtually impossible with conventional flat saw blades. Designed with a single continuous cutting tooth that rotates 360° around the length of a hardened steel wire, Spyral saw blades cut materials ranging from metals, plastics and ceramics to rubber, graphite and to wood to make them ideal for many construction, machining and craft jobs. and manufacturing applications.

Panafab“Conventional toothed saw blades are typically flat, cut forward and should be positioned so the teeth face the material at a right angle,” said Stuart Gordon, owner and president of Bestway. “Our Spyral saw blades cut in all directions, even sideways and backwards. They will cut in the direction of the feed pressure, which can make a significant difference when cutting without a rigid fixture. While other metal blades are limited to cutting only certain types of foam or require machinery that can cost hundreds of thousands of dollars, our Spyral saw blade can cut a wider assortment of foams as well as wood, plastic insulation, plastics and many metals without requiring expensive costs. specialized CNC machines.

After several initial conversations with Bestway, Panafab developed a cutting platform based on the company’s recommendations. This custom bandsaw was designed to quickly cut aluminum handles sequentially from their aluminum extrusion, requiring only two axes of motion to produce a single cut piece with the Spyral blade. This action would then be repeated continuously until the entire extrusion was consumed.

Before embarking on the design of a custom saw, Bestway suggested that Panafab send the extrusion material for test cuts. “Once we received the material and fully understood their manufacturing needs, we experimented with Spyral blades of different diameters until we developed a design that we thought would work,” Gordon said. “We had already put a lot of effort into developing a solder for the Spyral blade for use in continuous loop applications.”

Given Bestway’s extensive experience with systems like these, the company was able to provide Panafab with several recommendations within days of receiving fabrication details and testing the aluminum parts. Within four months of the initial outreach, Panafab was producing batches of 1,500 pieces of the aluminum handle with a 0.050″ Spyral blade making simultaneous vertical and horizontal cuts to precise dimensions in a single stroke.

“We’ve been working with this particular client for nearly 20 years,” Panetta said. “And they keep coming back because they fully appreciate the quality of our work and our ability to deliver on demand. This was a particularly challenging request that we fulfilled in extremely short timeframes and with incredibly accurate and cost-effective results. There’s no way this could have happened without Bestway.

“That’s what we do,” Gordon said. “Working regularly with companies to develop unconventional solutions for unique applications is our specialty. Sometimes the traditional blades used on existing bandsaws just don’t work. This app was perfect for us. They could have gone in other directions. But these systems would likely have cost hundreds of thousands of dollars to produce.
