HYDROSTATIC SPINDLES – WHEN TO USE THEM AND WHY The goal of this paper is to help manufacturing engineers determine and make the right decision on when it makes sense to use hydrostatic spindles for a particular application. Based on my personal involvement in the development and manufacture of hydrostatic
A COMPARISON OF ROLLING ELEMENT AND HYDROSTATIC BEARING SPINDLES FOR PRECISION MACHINE TOOL APPLICATIONS Dr. Kevin L. Wasson Hardinge, Inc. Elmira, NY USA INTRODUCTION The type of rotary motion bearings principally used in machine tool spindles are rolling element bearings. Spindles with hydrostatic fluid film bearings can be more desirable for
The Hyprostatik PMFlow Controller and hydrostatic components have been implemented in over 4,000 varied types of precision machine tools and components including grinding machines, measuring machines, highspeed machines, CNC lathes, machining centers, and milling machines, as well as large bearings and spindles.
The grinding wheel, regulating wheel, and tailstock used in this series all employ hydrostatic spindles. Spindle concentricity is within 2 µm on all spindles. These grinding machines are built for optimal precision and efficiency.
Grinding spindle solutions for a wide variety of machine types and applications. Our range of spindle units for grinding machines includes both internal and external cylindrical grinding as well as the respective dressing spindles. More. Special motors. In addition to spindles, WEISS manufactures special motor solutions for an exceptional ...
Hydrostatic bearing. The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding. It features high speed, no friction between metals, no heat generation, deformationfree and extra high accuracy. High rigidity structure
Ask about our "deep hole" ID grinding spindles able to accommodate up to 140" in grinding length for horizontal or vertical applications. Contact GCH to speak with an experienced sales engineer for quick, knowledgeable service about our grinder spindle inventory. Or, learn more about our spindle repair and rebuilding capabilities.
The spindle is a key component of a precision machine and it has significant impact on machined components in terms of form/dimensional accuracy and surface quality. Two types of spindles are most commonly used in precision machine tools,, aerostatic bearing spindles and oil hydrostatic bearing spindles. They are capable of high rotational ...
LPR Global provides precision machine tool spindles with diameters of 60230 mm and speeds up to 125,000 rpm for grinding, milling, and drilling machines. We manufacture a wide range of custom integral motor spindles and beltdriven spindles using hybrid ceramic ball bearing, air bearing, and hydrostatic bearing designs.
The Kellenberger KelVaria is a CNC controlled, universal cylindrical grinding machines with a directdrive workhead for grinding of large, heavy parts. "The torque drive allows heavy parts to be accelerated and braked with zero backlash during bidirectional movements," said a company spokesperson.
Typical applications are grinding operations on parts for hydraulic components, spindles, bearings, or gears as example. Voumard 1000 offers "almost infinite configuration options" for a wide range of grinding operations; it is designed to machine work pieces with a length of 300 mm and 300 mm swing diameter over the table.

The wheel spindle is supported by 20kg/cm 2 high pressure oil at axial and radial direction. ... During machine operation if grinding wheel unbalancing, the device automatic adjust wheel ...
Hydrostatic spindles or hydrodynamic spindles as tool machine spindles or main spindles have a very good radial accuracy. However, they have disadvantages in terms of rigidity and purchasing costs compared to spindles with roller hydrostatic spindles, the shaft is guided by the externally generated static oil pressure in the glide elements provided with oil pockets.
Precision ground hydrostatic bearing: Substantial decrease in heat deformation associated with hydrodynamic bearing. Minimal friction, lateral displacement, and tool life under heavy cut loads. The grinding wheel spindle runs on hydrostatic bearing with high pressure oil film for added precision under heavy loads.
