HOLRY ATC (Automatic Tool Change) spindle motor offers several advantages, especially for CNC (Computer Numerical Control) machining applications. Here are the key benefits:
ATC spindle motors allow for automatic tool changes, eliminating the need for manual intervention. This significantly reduces downtime and increases machining efficiency.
These motors ensure high precision and repeatability in tool changes, minimizing human error and improving the overall accuracy of machining operations.
With quick tool switching, the cutting speed and efficiency improve, leading to faster production cycles and optimized workflow.
Since tool changes happen automatically, less manual labor is required, leading to cost savings in terms of workforce requirements.
ATC spindle motors support a wide range of tool types, making them ideal for multi-functional machining tasks such as milling, drilling, engraving, and cutting.
Because tool changes happen smoothly and efficiently, wear and tear on the machine is reduced, leading to a longer lifespan for both the spindle and the machine.
ATC spindle motorsare ideal for mass production environments where frequent tool changes are necessary.
Automated tool changes reduce the need for operators to interact with rotating tools, improving workplace safety.
ATC spindle motor is a game-changer for CNC machining, offering speed, efficiency, and precision while reducing labor costs and improving safety. It is a valuable investment for businesses looking to scale their manufacturing operations.
The following is a detailed comparison between standard spindle motors and regular motors:
Usually have high rotational speeds, often reaching 10,000 rpm or more, and some can even reach 50,000 rpm or higher, which are suitable for high-speed machining equipment.
Generally have rotational speeds in the range of 1,500 - 3,000 rpm (for power frequency motors), which are sufficient for the needs of general mechanical equipment.
The rotor is made of high-strength materials like titanium alloy or carbon fiber. The bearing system often adopts magnetic levitation bearings, air bearings or high-precision ball bearings. They are equipped with special cooling systems such as liquid cooling or high-efficiency air cooling.
The rotor is made of conventional silicon steel sheets. The bearing system uses ordinary ball or sliding bearings, and a general air cooling system is sufficient to deal with the heat generated during operation.
Require dedicated inverters and precision control systems to ensure stable operation and response speed, and have higher requirements for electromagnetic design.
In most cases, they can run with ordinary power supplies, have low demand for frequency conversion control, and the control system is relatively simple and easy to maintain.
Usually have small to medium output power but high efficiency, which is suitable for scenarios where high speed and relatively low power are required.
Have a wide range of output power and moderate efficiency, which can meet common load requirements and are suitable for applications that require high power output.
Mainly used in high-speed processing equipment such as CNC machine tools and electric spindles, as well as in aerospace and medical equipment.
Widely used in household appliances, industrial equipment, and public infrastructure.
Have high research and development and manufacturing costs and are expensive. They require professional maintenance, with complex maintenance technology and high costs.
Have low prices, mature manufacturing processes, and are suitable for mass production. Routine maintenance is simple, with low costs and easily available spare parts.
Automatic Tool Change (ATC) spindle motor is a crucial component in modern CNC (Computer Numerical Control) machines, designed to enhance machining efficiency and precision. These motors are widely used in woodworking, metalworking, and industrial manufacturing due to their ability to automate tool changes without manual intervention. Below are the key features of an ATC spindle motor:
One of the most significant features of an ATC spindle motor is its ability to automatically change tools during machining. This feature eliminates the need for manual tool replacements, improving productivity and reducing downtime.
ATC spindle motors are designed for high-speed machining, often reaching speeds of up to 24,000 RPM or more. This high-speed capability ensures smooth cutting and engraving, making them ideal for precision work.
These motors provide strong torque and power, enabling them to handle a variety of materials, including wood, plastic, aluminum, and steel. The powerful motor ensures efficient and stable performance, even during heavy-duty operations.
With advanced bearing systems and balanced rotors, ATC spindle motors offer exceptional precision and minimal vibration. This results in higher machining accuracy and better surface finishes on the workpiece.
ATC spindle motors support multiple tool holder types, such as ISO, BT, HSK, and ER collets. This flexibility allows users to work with different tool sizes and types, expanding the machine’s capabilities.
To prevent overheating during extended operations, ATC spindle motors feature effective cooling mechanisms, such as air cooling or water cooling. This ensures long-lasting performance and reliability.
The built-in pneumatic or hydraulic tool clamping system ensures that tools are held securely during operation and released smoothly when changing. This feature enhances both safety and efficiency.
Designed for continuous operation, ATC spindle motors require minimal maintenance. Their high-quality components and durable construction contribute to a long lifespan, reducing machine downtime.
ATC spindle motors are used in a variety of industries, including:
Woodworking (furniture, cabinets, doors)
Metalworking (engraving, milling, drilling)
Plastic processing
Aerospace and automotive industries
Their versatility makes them an essential tool for high-precision and high-volume production environments.
ATC (Automatic Tool Changer) spindle motor is widely used in the field of woodworking, the following is the relevant introduction:
The ATC spindle motor has a cylinder structure at the tail, usually using air pressure to push the press block against the intermediate rod, so that the ER chuck extends outward to remove the tool. After that, the XYZ axis automatically grabs the tool, and the spindle motor solenoid valve releases the air pressure and cuts off the air source, thus completing the tool clamping and realizing the automatic tool change.
Efficient tool change: can automatically complete the tool change, greatly shorten the tool change time in woodworking processing, improve production efficiency, suitable for complex processes and frequent tool change tasks.
Equipped with high precision bearings and transmission system, it can ensure that the radial runout and axial movement of the tool when rotating at high speed is controlled in a very small range, to ensure the dimensional accuracy and surface quality of woodworking.
The speed can generally reach 10,000rpm-24,000rpm or higher, and the power range is usually 2.2kW-12kW, which can meet the requirements of different woodworking materials and processing processes for cutting speed and strength.
Air cooling and water cooling are common. The air-cooled structure is simple and easy to maintain. Water cooling heat dissipation efficiency is high, can effectively reduce the temperature of the spindle motor, suitable for high-power, long time working woodworking equipment.
for all kinds of furniture parts milling, drilling, engraving and other processing processes, such as cabinet door modeling milling, table leg drilling and engraving.
Solid wood flooring processing: Solid wood flooring can be slotted, mortise and tenon processing, etc., to ensure the installation accuracy and splicing quality of the floor.
It can complete the molding milling of wooden doors, the drilling of keyholes and hinge holes, and improve the processing accuracy and production efficiency of wooden doors.
Woodworking engraving: Whether it is simple pattern engraving or complex artistic engraving, ATC spindle motor can quickly change the tool according to the design requirements to achieve high precision engraving processing.
