NTL Industries founder and proprietor Greg McArthur thinks in target-concentrated preparing. “One of my preferred concepts was from Elon Musk. He said to have a 10-calendar year program but try to attain it in 6 months. You’re by no means likely to carry out it, but you will be a lot more ahead than if you weren’t seeking to carry out that larger 10-yr system.” All pictures courtesy of NTL Industries.
Greg McArthur grew up in the relatives machine store, fortunately performing the grunt operate even though he was continue to in substantial school — from cleaning to driving to shelling out Saturday evenings painting elements. He realized from his dad and uncle on the position, as perfectly as by means of courses at a regional neighborhood faculty. He parlayed this expertise and knowledge into getting a machine operator and total-time staff. Points have been likely perfectly, but like so numerous other equipment retailers in the state, this a person experienced from the fallout of the Good Economic downturn in the late 2000s and shut. But that was not likely to be the close of McArthur’s career as a machinist or in a loved ones enterprise.
He observed function with a hydraulics manufacturer, but dreamed of opening a producing business of his own. He and his spouse Shelley arrived up with a firm identify in excess of dinner just one night: NTL Industries. The acronym stands for “Never Far too Late” or “Nothing To Shed.” He says each work for the enterprise they introduced in 2017.
Currently that company has 11 workers and has lately added capabilities including horizontal machining. Noticeably, the desire has also expanded. McArthur is planning to develop into a manufacturer of aftermarket automotive components — and the horizontal machining heart will allow this. Below is how automated machining, exclusively functioning lights out, can allow for a single shop to run as a occupation shop by day and a creation maker by night.

Setting up With Growth in Brain
McArthur started off NTL by purchasing a Bridgeport knee mill and a CNC lathe to established up store in his 500-square foot property garage whilst still operating entire time. The CNC lathe was a specially significant investment, but he realized he needed the lathe to be programmable so he could operate it and the mill at the very same time.
He ongoing to get the job done whole-time and would devote various hrs each afternoon undertaking income for his own organization. “If everyone experienced a ‘help wanted’ indication, I’d halt in since obviously they had extra get the job done than they could cope with,” he suggests. “I’d leverage those people opportunities to get them by whichever they necessary,” building interactions and believe in amid these other shops. This helped McArthur mature the organization, and make long lasting interactions with other community stores, several of whom are nevertheless shoppers now.
In just six months, McArthur resigned from his job and fully commited to NTL Industries whole-time. He outgrew the garage and leased his very first creating in March 2019. By the conclusion of 2020, when the US was in the comprehensive throes of the COVID-19 pandemic, NTL had 8 whole-time staff members experienced included 3 Haas CNC vertical machining centers, a CNC plasma cutter and a welding office and had expanded to 3,500 square toes. NTL Industries also acquired its ISO-9001 certification at this time.
This 316 stainless-steel clamp is created of two distinct parts that were machined at the exact time. They had been run in a Kurt cluster vise in 3 set ups.
Imaginative and Strategic Enlargement
McArthur experienced generally prepared for the small business to be a lot more than a task store — he needed the capacity to realize some of his possess solution tips as perfectly, in effect starting to be an OEM. This goal served form the trajectory of his business’ progress. He purchased most of the equipment secondhand from eBay and Facebook Marketplace. But he understood he had to develop not only his equipment, which he did however obtaining machines secondhand from eBay and Facebook Market, but also his capabilities. So, he bought two Doosan (now DN Solutions) machining centers in 2021, both of those of them new, 1 of which was the shop’s initially horizontal machining center.
It was essential to McArthur to get the two machines from the similar builder. “I realized I was likely to invest in two machines, so earning absolutely sure the controls were being incredibly equivalent was significant to not possessing to study two different units,” he says. It was also vital that the machines have large enough tables and get the job done envelopes for massive components and output operates. Today, he and the staff function to establish how to very best established up areas and sequential operations on the equipment to maximize spindle time. They also develop quite a few of their very own workholding methods, created for economical setup and/or quick changeover.
He considered purchasing a 5-axis machine, figuring out it would develop NTL’s capabilities even a lot more, but the shop could not still justify the charge. “We’re performing 5-sided machining on our horizontal Doosan by spinning the part and remachining the other aspect,” he suggests. “I would appreciate to get into it with a serious 5-axis machine, and I will. It’s not a make a difference of if, but when.”
Castings also account for a substantial share of the occupation shop operate. The part on the suitable is a solid water pump housing been given from a client, while the section on the left is NTL Industries’ consider as machined on the DN Options NHP5000.
Functioning Toward Full Lights-Out Production
The DN Alternatives horizontal is a NHP5000 device. It has a 19.7” pallet, with a utmost workpiece measurement of 31.5” by 39.3”. The model NTL purchased has a 60-device capability and Renishaw probes for device and workpiece measurement.
The companion vertical is a DN Answers DNM5700S machining centre with a 51.2” by 22.4” table and 2200-lb. ability. The addition of these two equipment is already transforming the trajectory of the company’s development. By having entire advantage of the machines’ abilities, NTL can do bigger components in stacks of six or eight parts large and device all the faces of a aspect in just a couple of operations. The NHP5000 has a two-pallet program so the operator can set up for the next position and have it ready to load when an operation is accomplished managing, minimizing wait time among projects.
Brian Kozlowski is the operator of the HMC. With 24 years machining experience, he arrived to NTL right after functioning with McArthur at his prior employer. Kozlowski began his job undertaking on-equipment programing but now functions in Mastercam to program the DN Options machines.
This prototype section was machined on the HMC in both 7075 aluminum and 4140 steel. Machining was done 360 degrees around the aspect making use of the HMC’s fourth axis.
Latest Project Get the job done
Right now, NTL Industries focuses on a handful of vertical markets — agriculture and protection. The company manufactures a range of turned merchandise, alongside with at times complicated sections milled on its machining centers. Depending on the career, NTL may possibly commence from steel or aluminum billet or from castings.
One space of growth is workholding tooling for other outlets. “We can fill the voids when we have small downturns or holes in our working day-to-working day creation and enable out men like me when I very first started off out,” McArthur states. “We can aid them maintain their expenditures down,” leveraging some of what NTL has figured out about fixture tooling in the course of its possess do the job. This is the commencing of the organization sourcing its personal products, and the purpose is to go to lights-out manufacturing, significantly on the new HMC.
“We want to make absolutely sure the timing is proper. We really do not want to operate our equipment for eight several hours at 50%, slowing them down. The aim is to permit them operate at potential right away,” McArthur claims. “We want it to be as successful as attainable so we can gang elements and operate consecutive functions.”
NTL Motorsports is taking the shopper knowledge severely when tests its prototype rims for Jeeps: the company’s prime test matter is McArthur’s private automobile.
A New Small business Inside the Enterprise
In addition to the occupation store function, NTL has launched an offshoot model: NTL Motorsports. McArthur acquired the plan from observing his son, who is a go-kart racer, and now would make a line of aftermarket parts for go-karts.
“We’re starting with oil catch cans, but from there we’ll retain introducing to the merchandise line,” McArthur claims. He ideas for the shop to slowly but surely advance into this line of products, developing new offerings then transferring them into output as unattended capacity warrants.
“With the Doosans, we’ve got automation ability, and that will open more doors for us,” he claims. Recurring creation of his individual products can operate at evening, even though fewer-predictable occupation store machining can nevertheless fill the working day, when there are group members onsite to oversee the operate.
Also coming from the NTL Motorsports line: elements for authentic cars. The initially of these was a bumper for the Jeep design McArthur drives, with operations and welding executed in-household.
McArthur has currently refined the style and design for the future round of this product or service. The DN Solutions machines will allow NTL make various elements for the bumpers simultaneously with one particular established up. “We’ll be able to stack elements and slash all the holes and mounting openings at when because they will be copy areas. We’ll load the device and permit it operate all night time. The closing item will be superior than what we could do today simply because we’ll make a single integral body piece in the Doosan for the bumper and all the accessories — the lights, winch, and so on. Then you won’t have as several diverse components producing up the bumper, so there’s fewer room for it to break.”
A line of custom made rims is also in progress, starting up with protecting rims for McArthur’s possess Jeep. “We’ll produce common blanks that people can customise and structure to say what ever they want it to say. We’ll machine the rims on the Doosans and personalize with the plasma cutter. No matter what own touch you want to set on it, we’ll try out to make them completely customizable for our clients.” With concepts like these to go after, and with a thriving producing small business furnishing a platform to pursue them, the long run appears to be vivid — and relatively ironically, it appears all the brighter many thanks to lights-out output.
