Tell us a bit about your shop, how you got started, and what sort of products you manufacture.
TL Technologies got started in January 2012. Our first customers were firearms and defense based. Since then we have diversified our business through growth within customers and word of mouth. We started with the intent to be precise and accurate in a lights-out or nearly automated fashion.
What sort of machines do you use in your shop?
We use an array of modern equipment. 4 axis Kitamura HX400G Horizontal Mills. Nakamura Tome 9 axis Turn Mill, Star 6 axis, and two 5 axis vertical Hurco Machines. All our machines are optioned out with Renishaw probing and all the bells and whistles required to handle high accuracy runs for 24 hours a day with no process issues. Most of the machines have glass scales and thermal packages.
Which materials do you most often work with at your shop?
Mostly steels; the usual 4000 and 8000 series steels. Comparatively less 6061 and 7075 aluminum and other common stainless grades. We’ve been fortunate to have many of our materials within a reasonable range of Rockwell so that we may tool accordingly for most of the business.
How has your experience been with multi-axis machining?
Fantastic. Multi axis Machining has been excellent for us. It requires high-level understanding to fully maximize but the benefits are huge.
On your website, you mention that TL Technologies has never delivered a rejected part. What sets your quality apart from the competition?
From day one and job one, we worked with the customer to understand exactly how they were measuring the parts, exactly with what tools, processes, and methods to identically duplicate the process in our shop. After replicating key processes we performed many correlation studies to ensure that our measurements were within single-digit microns of what our customers were seeing on their end during inspection. This methodology was scaled up into our overall quality program and allows us to greater understand and manufacture our goods. Our ISO process coupled with this method truly does prevent bad work from getting out. We have never had a case where a part did not function or perform due to our oversight or bad specs. There have been failures on the customer side of things due to engineering, bad prints, and tolerance stackups, but we have not supplied parts that were flat out incorrect.
What sort of tolerances do you work in on a daily basis?
Typically single or double-digit microns. .0002” to .003” total is common for a large percentage of specs. It is not unusual for +/-.0002” to run long-term over many fixture stations with no manual adjustment. Our machined products are from 1” to 8” cubed.
What are some of the coolest projects you have had come through the shop?
That’s a good question. TL Technologies sat on the United States Senate committee in 2013 for Small Business and Entrepreneurship. We were featured on the cover of New York Times business section in 2013 as well. Throughout our years we’ve been fortunate to meet many amazing people from high branches in the government, the US Military, top name manufacturers, lenders, and local municipalities. Some of the coolest contacts were folks that formerly operated with US Special Forces. Unfortunately, we cannot comment.
As for projects not covered by an NDA, one of my personal favorites was producing low impact physical therapy products for rehabilitating shoulders after surgery. Though simple in manufacturing, this project provided an array of fun challenges that required high performance tooling, 3D printing, and using our machines with custom cycles. This allowed us to use the equipment very unconventionally. In this way, we were able to provide a cost-effective product utilizing the maximum ability of our equipment with a very short lead-time and low up-front cost.
You also offer assembly services on-site, which is fairly unique in the industry. Can you talk a little bit more about this?
Sure. Both my business partner and I have tremendous experience with assemblies in both hands-on and directorial roles. Whether it was a high precision multi-axis mechanism that ended up being a custom machine, on and off-road vehicles, or even things like child safety seats, we have had our hands in a lot of things over the years. At TL Technologies we’ve provided assistance to machine tool builders, special tooling designers, consumer goods of various types, and most frequently to firearms builders. Mostly we drive out cost, but as we age we’ve been called upon to troubleshoot high-end assemblies where the issues were not immediately apparent. This led to us creating sub-assemblies and even semi-finished OEM products. This includes hand fitting and assembling collectible pistols and precision bolt action rifles. This is usually offered as a temporary solution or process engineering service to larger companies developing new goods or revamping existing ones, and is offered as part of our comprehensive knowledge to attract clients. It has been very successful.
You service a variety of industries, including defense, automotive, agricultural equipment, and consumer products. Do you have a personal favorite?
I’d have to say the products we make that almost every soldier carries and relies on are my favorite. We take great pride in knowing that these parts have not failed due to machining error since we took over the production years ago on the core components.
Why is American manufacturing important to you?
It’s everything. It’s the heart and soul of all products and by extension facilitates the means with which goods and services exist in our society. By bolstering the skills, knowledge, and experience, we can not only succeed economically but also further the craft and pride of making quality goods. We will always need to be able to make our own goods. The skill and craft to create is more than just economic. We absolutely must embrace and respect the skill and hard work it takes to create. We must pass that knowledge on for posterity so the next generation might find the satisfaction and pride of skilled work.
Why is high-quality tool performance important to you?
It’s everything. The old adage, “Garbage in, garbage out,” is accurate for us. We feel that if we invested so much in these high-end machining centers, it would be criminal to put insufficient tooling and holders into them. We found that by selecting the proper tool with the appropriate sciences behind it we have been able to create products with a cost per cut that is not only competitive, but required to stay current. By keeping the quality as high as possible on the part making side of things, we’ve insured as much ease and reliability into our downstream process as we could. Quality tooling also provides predictability and added safety into the workflow. High-quality carbide tooling is the lifeblood of the business.
Have Harvey Tools had an impact on your performance?
Oh man…frequently. Harvey Tools are a mainstay in our company. If I had to think of some key examples it would have to be your variety of Keyseat Cutters, 3 Flute Counterbores, Extended Reach Ball End Mills, and Miniature End Mills under .040”. The 270 degree Lollipop Cutters are excellent for deburring, and we also rely on the 140° spot drills, corner radius forming tools, and more. In short, not only are the tools good, but they provide exactly what we need and the specifications to handle major OEM jobs. We absolutely love metric and you’ve got that too. Your catalogs help us eliminate the need for customs. That is key to cost and lead time.
If you could give one piece of advice to a new machinist ready to take the #PlungeIntoMachining, what would it be?
Embrace the old knowledge and techniques. The manual skills learned with files and hand ground tools translate critically into the concepts you will need to master if CNC becomes your career. Understand how and why materials cut or refuse to cut, what rake angle to use and when, and how to leverage machine physics to help you work smarter instead of harder. Don’t be afraid to jump down the rabbit hole of engineering concepts, materials, physics, elementary chemistry; these all help give you an edge. Machining is done best with comprehensive knowledge of the machines and machining environment. You never stop learning. All that said, keep a fresh perspective. Old knowledge can be great, but operationally each business will likely have its own methods and flow. Try to understand there is more to the overall business picture than you can often see.
Is there anything else you would like to share with the In The Loupe community?
Oh definitely! Buy our stuff!! Ha. We are a supplier of choice for OEM, and small batch bolt actions for rifles, pistol components, and pistol slides. We machine to spec and provide cost-competitive options as well as super-premium options. We are working now to release our own line of aftermarket products in 2018, so keep an eye out for those!
