Scott has made valid points regarding the electrical capacity of your building. I would say 400 amp for the service though. You always want to have room for some growth.
We supply transformers when applicable to our customers and they can run in the $3000 to $5000 range each depending on the size and voltages, so it is definitely something to consider. The machinery we carry is European with voltages from 380-400 volts three phase. Some European machinery requires a neutral. This means a Delta/Wye transformer is needed.
In my opinion, the used machinery market is on the weak side at the moment. There are a few good machines out there, depending on age, if you are purchasing from a company that needed to upgrade capacity. My observation on machinery up for sale in auctions, if the company was struggling financially, is that the machinery is not well maintained. When companies are having financial trouble maintenance is usually the first thing to go.
As far as brands go Scott is once again correct. The brands he mentioned as cheap are for hobby guys or those that have failed to understand the importance of having the right tool for the job. Scott is not familiar with Nutek Machinery and the machine lines we carry but I would encourage you and everyone else to take a look. Each line was handpicked by maintenance technicians with experience in production facilities of all sizes. Heavy built machinery that produces the highest quality parts on the market with a high level of production efficiency. The machines Nutek Machinery carries do not just look good on paper. They look good on your shop floor in production.
You will need to balance the cost to meet current capacities with machinery that will allow you to grow. There are two mistakes to be made.
1. Underbuying to meet only your current needs and finding you spent $50K on a piece of machinery that needs to be replaced in 1-3 years because it simply is not enough. No matter how you look at it, spending money that does not really get you what you need is throwing money away.
2. Overbuying and causing yourself financial hardship and setting yourself up for failure. You had mentioned that getting the work is the easy part, so you absolutely need to plan for growth.
Give thoughtful consideration to the number of cabinets you want to produce daily now and over the next 5 years. This will really help you focus on the right equipment.
My advice on the CNC is to make sure it is modular and can be added to. You may only need a stand-alone machine starting off but if you increase production in the future, you will want auto loading and unloading. Machining centers like ours run in automatic mode without an operator hitting cycle start. If the edgebander is placed at the outfeed of the CNC and there is a return system installed on the edgebander, one operator can run both machines. It does not take long to justify machinery like this if you are able to utilize one operator instead of 2 or 3.
The CNC should also allow you to do all of your vertical boring when you are nesting so I'm not certain you will need the boring machine in your drawing. If it is for horizonal boring for dowels I would just get a drill and dowel machine.
I look forward to talking with you in the near future Peter.
