14 times HELLER – Innovations are the secret of success

HELLER solutions at PMP Industries

Within only 20 years, PMP Industries located in Coseano has developed into one of the most renowned suppliers and references for complete mechanical and hydrostatic drives. For manufacturing, especially turning and milling operations, the company uses 14 HELLER machining centres of different types (MCi 25, MCH 250, H 4000 and H 2000). “For entrepreneurial reasons,” says production manager Dino Caporale, “we limit our cooperation to a small number of machine suppliers and in case of machines used for operations providing higher added value, we only work with HELLER.”

Task Setting

  • Reduction in production costs
  • Highly automated manufacturing line, enabling easy changeover and machining to very close tolerances
  • Manufacturing of complex products, including integrated motors and pumps, requiring high precision not only in terms of dimensional accuracy but also in view of flatness and angularity
  • Highest possible safety in production
  • Reliable and attentive technical support

Project scope and solution

  • Three machining centres model H 2000 and one H 4000 equipped with pallet changer, high-performance spindles and measuring probes
  • The H 2000 machining centres used are equipped with a pallet changing system, a PCU spindle unit with 38kW, 242Nm and up to 10,000rpm, a chain-type tool magazine with 80 storage places, an integrated measuring probe, Siemens-CNC Sinumerik 840D sl control, an optical path measuring system and HELLER zero spindle system

Result

  • Cycle time reduction of up to 35 percent
  • Minimised stock inventory
  • Due to the machine's high precision it was possible to eliminate the need for further milling operations in the final phase, enabling to complete the machining process in a single cycle
