Your question is somewhat vague. Various industries use a plethora of industrial equipment. The IMTS show in Chicago and EMO held alternately in Hanover, Germany and Milano, Italy are major trade shows promoting equipment by hundreds of manufacturers. Other smaller regional shows are held that are more specific to Metalforming, Machining, Grinding, Robotics, Material Handling, etc.
If you check out the IMTS website, providing your industry type and equipment needs, the machine builders will be sending their local contacts to assist you with your needs.
