Haas does not use Yaskawa. They use Lincoln Electric.
They do not publish information like this along with spindle or drive tourque curve charts. It is true that Haas would be good for someone starting out. The problem lies that very often as the company grows and productivity requirements go up, companies will tend to stay with Haas because the control is easy to use. Despite great Haas marketing efforts to prove they are the answer for all applications, if your profit is directly related to making chips, you will outgrow Haas capabilties. It takes more labor and cycle time to run Haas, Many people look at it differently. The machine's all do the same thing and that is a recipe for getting passed over by larger customers and leave you in a lower tier supplier role. Just one opinion that would fit other machines in the same class. Marketing and Popularity have brought them to the table for applications where they don't belong. I take nothing from Haas as its the buyers responsibility to be dilligent and educated.
