CNC Product Reviews & Testimonials

Here are just a few examples of what our satisfied customers are saying about our CNC Milling products. These are REAL PICS from REAL CUSTOMERS who have generously gone out of their way to take and send to us to show what they are machining with their CNC MASTERS Milling Machine.

A Hobbyist’s Testimonial

Being a hobbyist who enjoys designing rc model boats from the ground up, I have found the CNC Masters Milling Machine to be indespensible for the creation of custom design fittings, which in turn allow me to fit out my craft with one of a kind parts.

As well as being easy to use, this machine has provided me the means to not only create things, but learn new skills. I’ve always believed in the benefits of creating parts from scratch… why buy when you can have the satisfaction of diy.

Backup and support has been second to none, as I live in Australia all of my questions have been recieved with professionalism and in every case the solution is only an email or phone call away, from the helpful support crew. Thanks CNC Masters, you make my weekends memorable. lol.

Dear CNC Masters,

I just want to say “Thank You”. Your CNC Jr. has been a big help in my shop. It does about 90% of what my Bridgeport does at a fraction of the cost.

I sent along some pictures of the CNC Table Top in action and also some pictures of some custom motorcycle parts I made with it.

Dear CNC Masters:

In July 2001, we purchase your CNC Mini Mill and CNC Master software package. We have use the machinery and software in conjunction with two different 3-D CAD software programs, ArtCam and Cimigraphy. As you know, we added a rotary table to your setup and connected it to the y axis and use the fourth axis capability to cut cylindrical embossing wheels for our manufacturing process.

We have found that the mill will cut embossing wheels with acceptable tolerances using either of the 3-D CAD software program mentioned. We generally cut at a plunge rate and a feed rate of 40 inches per minute, often to 12 to 20 hours at a time.

We find the CNC Table Top Mill very satisfactory for our purposes, and wish you well with the marketing of this fine product.

Dear CNC Masters,

This letter is to complement on the good work you are doing with the Master software that runs the CNC Table Top Mill Machine. We produce our G-Code programs using Mastercam with a modified generic post processor in the Mastercam post processor folder. The postprocessor has been modified to match the CNC Jr. and now little or no editing is required once the G-Code program is produced. Here are some pictures of the parts I am cutting with the CNC Table Top Mill. and please continue the good work you are doing with the Master.exe program.

I have a small prototype shop, and already had an RF-31 mill/drill. I selected the CNC Table Top Mill conversion kit to augment the capabilities on hand, and to be able to machine complex shapes for some upcoming jobs.

The kit arrived in a timely fashion, and was well packaged. I ordered the 4th axis rotary table and the hand held remote options. I have some minor criticisms but overall I am very pleased with the system’s performance.

I had several “issues” with the system and the actual conversion. These were dealt with and resolved in a timely and professional manner by CNC Masters. In fact the “issues” I brought up with them have resulted in improvements to future models. They do have an excellent and evolving product.

All told my conversion took a little longer than their advertised time, due to taking the opportunity to thoroughly clean and re-grease my table components while apart.

OK, my “issues” having been resolved, the system is most excellent! Great accuracy/repeatability, and very easy to use and learn. (assuming you already are very adept at manual machining, and have some programming experience) And the system is a real joy to use compared to the tedium and drudgery of manual machining.

Within an hour or two of having the system completely assembled (4th axis not installed yet), and testing travels and getting used to the directions and so on, I had written simple programs in the Master Controller software, and performed some machining.

In the above image, a test block of acrylic was used to test the accuracy and play with manual programming in the Master Controller. Nice features and programming is VERY simple to learn. First cut at left was a big “oops”: feed too fast. next is a simple square using a 1/4″ 4 flute end mill, and doing 3 passes @ 0.100″ plunge increments. I wanted to test the accuracy in a manner consistent with manually doing this. The outline is bang on the program dimensions: 1.250″ x 0.750″

Then I wanted to try my hand at making a pocket bore for a bearing journal with an interference fit of the bearings I often use. Simple program using the arc command making several passes at larger arcs to the final dimension, and repeating at successive plunge depths. This took about 15 minutes to write and debug (you can “draw” exactly what the tool does in the master software to check), then about 8 minutes to cut. The bearing was a perfect interference fit first time out, with only this “roughing” and quick and dirty program! Man that is fantastic compared to taking an hour or two to do manually with a rotary table – getting close and measuring, eeking a little more radius and cutting again, measuring etc. This is going to be an immense time saver in addition to being able to make complex 2D and 3D parts!

OK, I elected to get 3rd party CAM software, i.e. BobCad. Once I learned the basics, I have begun making complex parts already (in less than a week since assembling the system, including ordering new tooling). Integration with master controller is a cinch, and machine performs flawlessly. (but as with any computer controlled system, GIGO garbage in garbage out – not only does your drawing have to be right, but you have to know how to machine things)

In closing, the CNC Masters CNC Table Top Mill conversion kit is a very good system, with some minor “issues”. But the issues were resolved quickly by contacting tech support, and the heart or core of the system is well done and performs nicely for the price.

PS: you really HAVE to get the hand held remote! I cannot imagine not having it. Getting the system without it is like ordering a new car without steering wheel and gearshift! (you can jog and position from within the controller software, but having this in the handheld, plus the micro positioning feature is something that makes system much better overall)

Thought you might be interested to know, we received our CNCJr / CNC Mini Mill last week and have spent this week playing around cutting different materials and learning the BobCAD software. We’re all very pleased with the machine, it’s far superior to anything we could buy in the UK for a similar price. Very easy to use and gives excellent results.

Thanks for all your help with the machine pickup it was worth all the hassle in the end!
