Spindle Motor Used for Grinding Spindle

Spindle Motor Used for Grinding Spindle

The main products can be divided into 5 styles with more than 10 series, the speed from 600r/min To 110.000/min. the power from 0.05kw to 40KW, the spindle bearing according to different speeds using high precision and speed bearing, or ceramic bearing, or maglev bearing. The cooling way uses oil, oil fog, and oil gas, We also can design it for your requirement.

What Is a Spindle Motor?

The main purpose of the spindle motor is to move the workpiece at a specific speed. The motor is also used for special work requirements such as tool change and tool retraction. It is synchronized with the servo axis to control the movement of the workpiece. In addition, multiple spindles can run simultaneously and synchronously.The speed of the spindle is the determining factor in the amount of material that can be removed and the finish of the finished product. High-speed spindles can spin up to 24,000 RPM, while low-speed spindles can spin up to 6,000 to 15,000 RPM. The higher the speed, the more force the spindle can exert. However, high-speed spindles are more expensive than low-torque spindles.The rotor is also a key component of the spindle motor. It must be properly balanced for smooth operation. When the spindle rotor is uneven, it can cause vibrations that can damage the tool or overheat the motor. Also, it can damage the spindle. Therefore, it is critical to keep the balance of the rotor within tight specifications.

There are Two Ways for the Output One is Constant Torque, and Another is Constant Power as Below:

Nomenclature Explanation of Motor Spindle

The End of the Spindle Connection

Its have many different types of connection, depending on the different model spindle, please refer to the table below.

Spindle Instruction

1. The frequency converter must match the electric spindle unit. The fundamental frequency or the nominal frequency and the voltage must meet the technical parameters of the electric spindle.2. Electric spindle is usually cooled by circulating water. Cooling water should be rust-proof and filtered clean. When receiving water, the inlet should be below the electric spindle.3. When using an oil mist lubricated spindle, the pressure regulating valve of the oil mist device should be adjusted to 0.25~0.3 MPA the fog pressure should be 0.1~0.2 MPA, and the number of drops of oil should be 60-70 drops/min. and the lubricating oil should be bell oil or turbine oil No. 20.4. The speed on the motorized spindle manual is the highest speed, and it can not be increased, but it can be used to reducethe speed and voltage and frequency are reduced when the speed is lowered.5. The rotation direction of the motorized spindle is usually counter-clockwise (viewed from the shaft). except for specialrequirements.6. The motorized spindle lubricated by oil mist must be connected with water and gas before it can start and stop water and gassupply after shutdown.Explanation: specific operation is required according to the electric spindle instructions.
