STARWAY HV-40 VERTICAL MACHINING CENTER

Technical Description

This CNC spindle assembly features dimensions of 15.75 inches (X-axis), 11.81 inches (Y-axis), and 11.81 inches (Z-axis), designed for precise 3-axis machining control. It operates at a maximum rotational speed of 15,000 RPM, suitable for medium-to-high-speed milling and cutting operations, particularly in materials like steel, where this speed balances cutting efficiency and tool life. The spindle is controlled via CNC, ensuring automated, precise positioning and repeatability. The 15,000 RPM rating aligns with belt-driven spindle designs, which provide higher torque at moderate high speeds, typically featuring air or liquid cooling to manage thermal stability during operation. Such spindles are built with precision bearings (such as ceramic or ABEC 9 rated) to minimize vibration and maximize rotational accuracy, critical for maintaining surface finish quality and tool longevity. The spindle motor generally ranges from approximately 3 kW to 7 kW power, offering an optimal balance of torque and speed to support tooling diameters up to around 10-16 mm depending on the application and material hardness. The CNC control facilitates exact feed rates and spindle speed adjustments for diverse machining tasks, from roughing to fine finishing. This unit’s size and RPM make it suitable for use in industrial machining centers for metals including steel and aluminum, plastics, and composites, operating with high consistency and reliability. Ancillary features likely include tool holders compatible with ER collets and integrated cooling systems to prevent thermal distortion during extended runs, ensuring high throughput with precision.
