Product Introduction

This ATC Spindle Diy spindle is a dedicated power unit for CNC machining, supplied by Lishui City Hengli Automation Technology Co.,LTD. Available with ISO20, ISO30 and HSK63F tool holder interfaces, it uses P4 high precision bearings, covers 2.2 - 4.5 kW power range and reaches max 24000 rpm. Built in DC fan provides effective cooling, together with precise tool - change detection sensors for stable performance and easy maintenance. Widely applied in woodworking engraving, metal cutting and precision milling centers. It realizes pneumatic automatic tool change with tool clamp & unclamp detection sensors and integrated PTC over-temperature protection to feed real-time operating status to the control system. Compatible with automatic tool magazines for tool switching without manual intervention, supporting both rough cutting and high precision finishing.

Compressed air serves as power source. Air cylinder mechanisms drive the built-in tool gripper and pull-rod assembly to clamp or release cutting tools. PNP position sensors collect signals for tool unclamp and clamp status. Receiving commands from CNC system, the spindle completes the full cycle: unclamp → tool change → clamp, switching cutters automatically to enable multi-process continuous machining.

22KW Specification

Adopting air-cooled structure for simple installation and low - maintenance operation. Square housing provides high rigidity; grease-lubricated bearings ensure low noise and stable running. Built-in tool-change signal feedback and over-temperature protection improve operation safety. Wide speed range with excellent constant-power & constant-torque output. Compact size and moderate weight make it compatible with gantry and vertical CNC machines.

Integrated high-speed structure: Motor and spindle are combined into one unit without intermediate transmission for zero transmission clearance. Max speed up to 24000 rpm with low vibration and superior workpiece surface finish.

45KW ISO30 Specification

1.Air-cooled design without chiller:

Built-in DC24V cooling fan eliminates the need for water chiller, water pipes and water pumps. Perfect for space-limited machines and reduces maintenance workload.

2.Closed-loop automatic tool-change：

Pneumatic clamp/unclamp plus dual position sensors allow CNC to read tool status, preventing machining with poorly-locked tools and lowering collision risks. Partial models feature manual tool-release button for convenient commissioning.

3.Comprehensive safety protection:

Integrated PTC thermistor sends fault alerts upon winding overheat. Front-end air seal blocks dust and cutting chips to extend bearing service life.

4.Multiple standard tool-holder options:

ISO20, ISO30, HSK63F available to satisfy applications from fine precision machining to medium-duty cutting.

5.Square-shape housing:

Direct locking on machine frame without extra cylindrical clamping seats, easy assembly and stable mounting accuracy.

45KW HSK63F Specification

6.Stable performance curve:

Wide constant-torque range delivers sufficient low-speed torque; stable constant-power output supports both rough milling and high-speed finishing.

Application Scenario	Model	Tool Holder	Speed(rpm)	Power
Compact size machines for precision engraving, small aluminum parts, PCB & woodworking, small cutting depth	GDL40.5-24Z	ISO20	24000	2.2kW

Summary

Pick 2.2 kW ISO20 for light-cutting compact machines; choose 4.5 kW for medium-duty cutting; select HSK63F tool-holder version for high-precision metal high-speed machining. This is also a popular configuration for ATC Spindle Diy builders.

Driven by matched-spec inverter; compatible with ISO / HSK series tool holders. Air source needs pressure regulating filter valve for stable air pressure. Works with automatic tool magazine. The control system shall receive spindle tool-change sensor signals to realize coordinated tool-change logic.

No water chiller required, simple installation, low maintenance and tidy workshop layout. Suitable for intermittent light-to-medium-load multi-tool-change jobs. Ideal for water-shortage or low-temperature overseas regions, small workshops and export-ready complete machines.
