Spindle Motor Used for CNC Spindle JSZD320

The main purpose of a spindle motor is to move the workpiece at a specific speed. This motor is also used for special work requirements such as tool changing and tool withdrawal. It synchronizes with a servo shaft to control the movement of the workpiece. Moreover, multiple spindles can be operated simultaneously and synchronously.The speed of the spindle is a determining factor for the number of materials that can be removed and the finish of the finished product. High-speed spindles reach speeds of up to 24,000 RPM, while low-speed ones reach between 6,000 and 15,000 RPM. The higher the speed, the more force the spindle can exert. However, high-speed spindles are more expensive than low-torque ones.

Choosing the Right CNC Spindle Motor Type

There are several different types of CNC spindle motors. One is a stepper motor and the other is a servo motor. The basic principles of the two are similar, but the speed capabilities are different. Stepper motors work by sending electrical pulses through a wire wrapped around a permanent magnet. The motor then rotates the spindle with high speed and high precision.Spindle motors are designed to rotate at high speeds, so they are extremely durable and have tight tolerances. Standard bearings are not suitable for spindle motors and can overheat quickly. You will need special bearings designed for high speeds. These are expensive and require specialized tools for installation. A mistake in one of these parts can cause expensive damage.Spindles come in many sizes and types. Some are self-contained, and some are cartridge-style. Cartridge spindles are easier to replace than manufactured ones. These spindles have two deep groove ball bearings and two angular contact bearings, which determine the maximum speed and stiffness. They also contain a pull rod that pulls the tool holder into the spindle taper.Choosing the correct spindle motor type depends on your application. If you want to cut soft materials, an aluminum spindle may be the best choice. However, if you need to cut hard metals, a cast iron or steel spindle is recommended.
