With the type of bearings the spindle has 3000 rpm is just about max. And even if it was american made it will be no better for the size of machine. The problem is with quality control the chinese have none. With the rising cost of fuel and food. They wont sell very many machines until after the recession we are going through. So by that time they might improve but at this point it's hasn't happened. They need to improve on the castings . The earlier castings were better than the newer ones. They took a step backwards and they need to stop cutting corners before they cant sell anything because people will want quality for the money they are spending.
