Our Services
Specialized services designed to improve spindle life, accuracy, and overall machine performance.
Hydrostatic Spindle
Hydrostatic spindles represent the absolute pinnacle of machine tool precision. Unlike standard spindles, they do not use mechanical ball or roller bearings. Instead, the rotor shaft floats on a highly pressurized, microscopic film of oil (or sometimes air, in aerostatic models). Because there is zero metal-to-metal contact during operation, they offer infinite theoretical wear life, incredible vibration damping, and sub-micron rotational accuracy. However, when they fail—usually due to oil contamination, blocked capillary restrictors, or a drop in hydraulic pressure—the resulting high-speed metal-to-metal crash causes severe scoring to the bearing surfaces. Rebuilding them is less about replacing parts and entirely about ultra-precision machining and fluid dynamics.
Milling Heads
Reconditioning a CNC milling head—whether it's a right-angle head, a universal bi-rotary head, or a heavy-duty attachment—is a precision engineering process. These heads endure massive torque and complex multi-axis forces, meaning even microscopic wear on the internal bevel gears or bearings can ruin surface finishes and destroy tools.
Hydrodynamic Spindle
While hydrostatic spindles rely on external high-pressure pumps to float the shaft, hydrodynamic spindles generate their own fluid pressure. As the spindle shaft rotates, it acts like a pump, drawing oil into a microscopic wedge-shaped gap. At operating speed, the shaft effectively "hydroplanes" on this pressurized oil film, providing massive radial load capacity and exceptional vibration damping. Because they rely on rotation to create the oil wedge, there is always brief metal-to-metal contact during startup and shutdown. Over thousands of cycles, or if oil viscosity breaks down, this friction causes scoring on the shaft journals and the soft metal bearing sleeves, requiring specialized restoration.
