At the heart of a machine tool is the precision spindle, used to apply the level of torque, speed and accuracy required for a particular spindle machining application. While most spindles have hundreds of parts, there are several accessories that primarily affect the spindle.

CNC spindle repair part 1: CNC Spindle Gripper

CNC spindle gripper is a mechanical device used to clamp and hold a tool, usually located at the front of the spindle, and secured to the spindle by a spigot.

CNC spindle gripers provide a strong clamping force to ensure that the tool remains stable during high-speed rotation and cutting, preventing it from loosening or breaking. They are suitable for all types of CNC machine tools, including lathes, milling machines and machining centers, especially those with BT, HSK or other standard toolholder interfaces. CNC spindle grippers are essential to ensure tool stability and safety during machining, directly affecting machining accuracy and tool life.

Rico supplies various CNC grippers for many different brands spindle, such as MAZAK, DMG MORI, ENSHU, FANUC, DOOSAN, etc. We can supply spindle grippers brand as Riken Seiki, Doosan, Acrow, Bright, Chumpower, OTT-JAKOB ,Royal, Talons, Yibao, SM, etc.

CNC spindle repair part 2: CNC Spindle Rotary Joint

A Spindle rotary joint is a mechanical tool that lets in the switch of fluid from a stationary supply to a rotating detail. The CNC spindle rotary joint is a sealing device that allows coolant or air to pass through the spindle as it rotates, to cool the tool and spindle.

CNC spindle rotary joints ensure a continuous supply of coolant or air as the spindle rotates to cool the tool and spindle, prevent overheating and maintain spindle performance. CNC spindle rotary unions are mainly used for electric and mechanical spindles that require an internal cooling system, especially for high speed machining and precision machining. The CNC spindle rotating joints are essential for maintaining spindle and tool temperature control, helping to improve machining efficiency and extend tool life.

Rico supplies various CNC spindle rotary joints for many different brands spindle, such as MAZAK, DMG MORI, ENSHU, FANUC, DOOSAN, etc. We can supply spindle rotary brand as RIX, Deublin, OTT-JAKOB, ROTOFLUX, SMARTC, etc.

CNC spindle repair part 3: CNC Spindle Motor

CNC Spindle motor is the key component to provide cutting force on CNC machine tools, driving the spindle rotation directly or through the transmission system.

The CNC Spindle Motor can provide precise speed control and high torque output to meet different machining demands and ensure stable speed. they are suitable for various types of spindles, including belt-driven spindles and coupling-driven spindles. CNC Spindle Motor directly affects the machining capability and efficiency of the machine tool, and is the core component of the CNC machine tool.

Rico can supply Spindle motors for HOMAG, BIESSE, SCM, etc. Motor brands such as YASKAWA, Nidec, Panasonic, also many Chinese brands etc.

CNC spindle repair part 4: CNC Spindle Encoder

CNC Spindle encoder is a sensor used to measure the speed and position of a spindle, providing accurate speed and position feedback.

CNC Spindle encoders are used in closed-loop control systems to ensure precise spindle control and improve machining accuracy. These encoders are suitable for use in a wide range of spindle systems where accurate speed and position feedback is required, particularly in automatic tool change and precision control applications. CNC Spindle encoder is critical to achieving high accuracy and efficiency in machining, especially in the manufacture of complex parts.

CNC spindle repair part 5: CNC Spindle drawbar

The spindle drawbar is a mechanical component used to transmit the tension force for clamping the tool, and the axial force transmitted by the drawbar realises the tensioning of the toolholder.

CNC Spindle drawbar is to realise quick loading and unloading of tools on the spindle and automatic clamping, to improve tool versatility and reduce production costs. Push Rod Assy are suitable for spindles using tie-rod clamping systems, including some machining centres and CNC lathes. CNC Spindle drawbar (spindle tie-bar) is to realise the automatic clamping and changing of tools, to improve tool versatility and to reduce production costs.

CNC spindle repair part 6: CNC Spindle Disc Spring

CNC Spindle Disc Springs are thin sheets of material used to adjust or fill gaps between mechanical parts, usually made of metal, rubber, plastic or composite materials. Their primary function is to provide sealing, cushioning, support or adjustment in mechanical assemblies.

CNC Spindle Disc Spring can adjust bearing clearance, optimise preload, improve spindle rigidity and precision. Protects spindle and bearings, reduces wear and prolongs service life. These Spindle Disc Springs are suitable for lathe, milling machine, grinding machine and other kinds of CNC machine tool spindle. CNC Spindle Disc Spring are critical to ensuring machine accuracy, stability and extended spindle life.

CNC spindle repair part 7: CNC Spindle Tension Gauge

CNC Spindle Tension Gauge is a measuring tool used to measure the force with which a spindle pull grip clamps a tool.

Spindle Tension Gauge Function is to ensure that the tool is correctly clamped and to prevent the tool from loosening or breaking during machining. These Tension Gauges are suitable for all spindle systems where the pulling force needs to be measured. Spindle Tension Gauge (Spindle Tensiometers) are essential to ensure secure tool clamping and machining accuracy.

CNC spindle repair part 8: CNC Spindle Test Bar

CNC Spindle test bar is a tool used to inspect the accuracy of the spindle, which is used to measure the radial and axial runout of the spindle to ensure the machining accuracy of the spindle.

CNC Spindle Test Bar is to detect and adjust the deviation of spindle in time to ensure the machining quality by detecting the accuracy of spindle. They are suitable for spindles with BBT interface, used for detecting precision items such as radial circular runout, axial runout and coaxiality. CNC Spindle Test Bar (Spindle runout) is essential to ensure the machining accuracy and stability of the machine tool.

In addition to the above components, other repair components for the spindle include:

Spindle bearings: support spindle rotation, reduce friction and wear, and ensure smooth operation.

Spindle seals: protect the spindle from cutting fluids and contaminants, maintaining internal cleanliness.

Spindle Cooling System: Provides cooling to the high-speed rotating spindle to prevent overheating and ensure reliability.

Spindle Lubrication System: Continuously lubricates bearings to reduce wear and extend spindle life.

etc.
