​TESTIMONIAL: 
My small business recently purchased an Acer E-mill 3VK with an Acu-rite 3 axis CNC controller.

Prior to making the purchase I went to Rossi Machine to talk with them as I had a lot of questions.

I have never purchased a new machine before. The Rossi’s took the time to answer all of my questions and we spent a couple of hours just talking machining.

I soon became confident that these folks know their products and how to service them. I felt that these were folks that I could put my trust in.

​ My new machine arrived and went into service without any problems. Our labor input for our parts were cut by about 60%. 

After the machine was in service about a month a warranty issue popped up. I called Mike Rossi and he came to the shop in a little over one hour. He quickly located the problem with the controller. My machine was repaired and back in service with minimal down time.
 
Rossi Machinery is a company with honesty, integrity and the skills which I was looking for in a machinery dealer. You can depend on them, I do.
