30 years ago this month, November 1983, J&D Machine started in the basement of our family home in New Hampshire. Back when we started, we only had a few cam machines and a cam shaper, and we did not know that we would become the successful CNC machining company we are today. 30 years later we only have CNCs (and a few more of them). In 1985 we moved into our first commercial space. We had 1250 square feet in our unit, and that’s when we added our first CNC machine. Back then we did a lot of electronics work as well as defense work. We stayed in that space for about 12 years and eventually tripled our space in 1997 when we purchased 3 identical units a few buildings over. This is where we still do business today. We currently have about 4000 square feet of manufacturing space, and 7 CNC machines. At our peak in 2009, just before the recession hit, we had 9 CNC machines.

CNC Machining to 3D Printing
3D printing is becoming quite popular in the media these days. The idea that you can “print” something out of raw materials seems like something out of a science fiction movie, yet people are really doing it with this amazing technology. But what does it mean for the state of manufacturing? As I research about 3D printers I’m reminded of the changes in manufacturing that came about with the advent of CNC, or Computer Numerical Control. CNC changed manufacturing forever, making more complex parts a lot easier to create.
3D printing is somewhat of a natural progression from CNC turning and milling. In CNC, you’re starting with a rod of material and using tools on the X and Y axis, along with a moving Z axis to cut away the material until you have your desired shape. With 3D printing, you’re using the same X, Y and Z axes, but you’re putting down the material instead of taking it away, cutting the cost of tooling and fixturing.
But what will 3D printing do for CNC? I think it will improve it. There are already plenty of combination CNC machines and 3D printers, and since CNC shops are already used to CAD systems, I see the CNC shops that are heavy in prototyping adopting 3D printing and outfitting their shops with 3D printers.
3D printing is still in its infancy. Those who can remember back to the early 80’s, when CNC was just coming about might see some similarities between the two. 3D printing definitely has the same potential that CNC had back then.
When it comes to mass production, CNC is still the most cost effective and the fastest. Of course that could change because, as we know, anything is possible.
2013 – CNC Machining – Looking Ahead to the New Year
As we begin the year 2013, at J&D Machine, we are cautiously optimistic. With 2012 ending well in the CNC Machining world, in the hopes that 2013 will continue this way, we are making plans to add a new piece of equipment in the 2nd quarter. After our longest stretch of time without purchasing new equipment, we look forward to the process and seeing how much has changed in the last four years.
We have been working on some great new projects recently. CNC Machining projects that are small (but important) parts of exciting advances in robotics, defense, and aerospace. We are seeing a lot of new product quotes that we haven’t seen before, and that’s very encouraging.
Although nothing is etched in stone, this is a good sign that things are getting better in the CNC Machining industry, and we are excited to be a part of it.
Forging Relationships with Other Machine Shops
Here’s an example of a job that was sent out for silver plating.
One of the best things you can do to grow a CNC machine shop is to develop long-lasting relationships with other machine shops. It’s important not to look at all the other businesses in your industry as competition, but as colleagues. Not only does it help to have support from the manufacturing community when you need it, but it’s also important to have trust in other machine shops that have different specialties when you need them. It’s difficult for a CNC machine shop to be good at absolutely everything. There are many jobs that we have to send out to our friends to make sure they are of the highest quality possible. We send out jobs for heat treating, grinding and plating, and we are lucky to have a few go to shops that we can trust with every job we send their way. Since turn-around time is usually stressed in our industry, we need to make sure that all our work is done right and on time every time. The bonus is that the work we send out is usually reciprocated when these shops get work in that requires one of our specialties, any small CNC turning or lathe CNC turning.
CNC Machining – A Small Part of a Big Deal
In CNC Machining, every once in a while a job comes along that’s not the most profitable or the longest running order, but that is just kind of neat. That happened to us recently. A customer of ours with a parent company in England contacted us about doing a rush order for the Sailrocket Team. Not knowing anything about Sailrocket, I looked them up on the internet and found out they are a team of sail boat racers trying to set a new sailing speed record. That was cool enough for us to say yes to the project.
The Return of Cam Machines?
I recently read an article from a machine dealer that said that, after years of inactivity, he has been receiving requests for turn key cam machines. These requests have been coming from Asian manufacturers. I believe, but am not sure, that cam machine production stopped completely around the year 2000, and now all single spindle screw machines are CNC. For us here in the United States, the move to CNC machining was necessitated by our changing job market. Our lot sizes became smaller, and the need for versatile set up and ease of programming became as important as, if not more important than, cycle time.
