CNC Spindle Motor, Grinding Machine Spindle

                             

Motorized Spindles are widely used as replacements for the main spindle by CNC machine tool manufacturers. CNC Spindle Motor available for centerless grinders, ID grinders, OD grinders, double-disc grinders and surface grinders. 

1. Tool Grinding Motorized Spindle
(double-head grinding spindle, automatic grinding wheel replacement grinding spindle, high-frequency peel grinding spindle)

Tool grinding Motorized spindles are mainly used in automatic CNC tool grinding machines, which can rotate in both directions and grind in multiple directions, and are used for processing various sizes of tools such as drills, milling cutters, taps, turning inserts, etc. Tool grooving and sharpening is completed in one clamping process; this series of Motorized spindles can not only withstand large radial force, but also a certain amount of axial tension and thrust, and has the characteristics of high precision and high rigidity.

With the development of tool grinding Motorized spindle, the motor gradually adopts copper rotor or permanent magnet synchronous motor, the motor efficiency and energy saving are improved simultaneously, and the pressure air sealing technology is adopted to improve the air sealing structure, which ensures the reliability of spindle operation and long life of 24-hour continuous operation.

Grinding Spindle for Tool Grinding

 • Compact, high-torque and high-performance spindle systems for the production of cutting tools
 • Razor-sharp cuts thanks to high rigidity and robust bearings
 • Minimal axial shaft displacement
 • Automatic tool clamping system or double-sided tool interface
 This is the only way for machines to achieve a very good cutting performance and the best surface quality of the tools to be machined.

 

2. Motor Spindles for External Grinding

High Frequency External Grinding Spindle/ Surface grinding spindle have In-built motor at the rear end. These spindles are use where high surface finish is required. Spindle's RPM can be increased or decreased with the help of frequency drive to suit job requirement. It may be horizontal or vertical. It will give remarkable surface finish for sharpening of cutter blades & High profile precision Components. 


CNC External Grinding


 • High torque and high power density due to high-pole Sychronous motors
 • Peripheral speeds up to 140 m/s
 • Robust and high-precision bearing systems
 • Guaranteed concentricity accuracy within 0.002 mm (2 microns)




 

3. Motor Spindles for Internal Grinding

A high-speed internal grinding electric spindle is a specialized device used in precision grinding operations. It is designed to provide high rotational speeds and precise control for grinding applications performed inside cylindrical workpieces. 

Internal Grinding
• Machining of a wide variety of workpieces, both cylindrical as well as end faces, tapered and spherical parts
• Spindles with highest speeds for high cutting speeds
• Spindles for sophisticated deep-hole grinding
• Highest running smoothness and precision
• Universally loadable bearings for radial, axial and combined grinding forces
• Cooling and Lubrication: help dissipate heat generated, preventing thermal damage to workpieces, maintaining performance of the abrasive tool



 

4. Motor Spindle for Micro Drill

Smart Spindles, Smart Drilling
What kind of sensors are most useful to end-users? 
Vibration, torque, and—when drilling or milling holes—sensors that measure the diameter of the hole. 
• There are many effects you can measure and control with vibration. By measuring the baseline vibration pattern with a process under control, any variation from that vibration target means problems. If contact between the part and the tool is wrong, if the tool is broken, unbalanced, or chattering, the vibration pattern will alert the controller to adjust.
• Torque variations again provide useful information about processes going wrong. Abrupt changes in its pattern can detect chatter or a broken tool, as well as expected changes in material. this is useful in drilling holes for joining dissimilar materials, like aluminum and carbon-fiber reinforced plastics (CFRP) common in aerospace. The control is smart enough to adjust the drill as it cuts from aluminum to CFRP to aluminum in a stacked material.
• By measuring a diameter in-process, you can adjust that process and know either how much material to remove or to compensate the spindle. This makes for accurate drilling and milling within
