Spindle Core and Jacket Cooling System Control Machine Heat
Makino's compact D200Z machining center has 30,000-rpm, HSK-E50 spindle that is designed with a high-tech spindle core and jacket cooling system to tightly control thermal growth, deflection and vibration during high-speed machining operations.
Makino says its D200Z boosts productivity for complex dies and molds typically found in the automotive, injection molding, packaging, medical and optical markets. The design of the D200Z combines speed and precision into a compact unit that is 1500 mm wide and 2220 mm deep for efficient use of floor space. All machine elements and peripheral equipment are strategically located within the main body of the machine to limit the overall machine footprint. Both the standard 20-tool capacity automatic tool changer (ATC) and the optional 40-tool ATC fit within the same machine floor space, enabling companies to expand capability without loss of floor space. In addition, the machine tool magazine capacity can be optionally expanded to 100 and 300 tools.
Wide base castings and core-cooled ball screws serve as a base platform for all other machine components, enhancing overall process stability. The machine’s 30,000-rpm, HSK-E50 spindle is designed with a high-tech spindle core and jacket cooling system to tightly control thermal growth, deflection and vibration during high-speed machining operations. Makino says that as a result, the D200Z extends tool life and has high-quality surface finishes even in applications requiring fine tool blends and matches.
In today's moldmaking market, selecting proper parameters of the machining operation to avoid.
When evaluating new processes for mold manufacture, jig grinding is worth a second look as machine manufacturers have now added high accuracy features to guarantee repeatable results.
Negative stock shutoff can help you make better molds in less time. Here is a clear definition and description of the process. While the concept is fairly simple, the implementation can be challenging.
