The Bridgeport Torq-Cut 22 is a smaller CNC vertical machining center. It comes fitted with a grease lubricated and belt driven spindle capable of running up to 7,500 rpm.Read More
SPINDLE REPAIR GLOSSARY
The glossary section is here to increase your understanding of spindle related terminology. If you need additional information, please contact us, we love to talk about what we do.
The stator is the stationary part of the electric 3 phase induction motor system found in a spindle. It can also be known as a field. The stator consists of wire windings that when energized create a magnetic field that pushes the rotor making the spindle shaft rotate.Read More
Roller bearings are used in spindle applications that require a high level of radial load capacity. Some examples of this are large centerless grinding spindles, large low speed milling spindles and spindles that have radial loads from drive belts.Read More
CERAMIC DISC TYPE ROTARY UNIONS
Ceramic disc type rotary unions are used in machine tool spindle applications of various makes, models and applications. This is a typical set up where one end mounts to the drawbar and one end mounts to the machine.Read More
A thermistor is a type of resistor whose resistance varies with temperature. Spindle usage: Thermistors are placed on or near the spindle stator to monitor the heat of the motor windings. The machine control monitors the outputs of the thermistor and if the outputs reach an overheat level the spindle is shut down.Read More
The Spindle Shaft consists of the Pulley Taper, Bearing Journal, Shaft Pilot, Threads, Shoulder, and Shaft Tooling Face. Definitions and explanations of each individual component are described here.Read More
The Spindle Housing is home to the Flange Housing Flange, Shoulder, and the Bore Housing Bearing Bore. Definitions and explanations of each individual component are described here.Read More
The rotary union of a spindle is mounted to the rear of the shaft and it permits the movement of liquid from a stationary point into the rotating shaft. Typically rotary unions are used for the transfer of coolant in through tool coolant applications.Read More
What is a Rotor?
The rotor is the non-stationary part of the electric 3 phase induction motor system found in a spindle. It is part of the spindle shaft. It rotates because the wires and magnetic field of the motor are arranged so that a torque is developed about the rotor’s axis.Read More
Preload of Angular Contact Bearings
Preloading bearings is the process of removing the internal clearance of the bearing by applying a permanent thrust load. This applied force makes the rolling elements run in a single “track” and it removes any axial play in the bearing assembly.Read More
The success of any precision machinery relies heavily on various intricate components working seamlessly in unison.Read More
