Why this range
Engineered for direct machine integration
From holder family to platform tier, every model in this range is defined by measurable parameters — so procurement teams can narrow the selection without ambiguity.
Focused Interface Coverage
Every model in this range uses either BT30 or HSK40E interface, covering the two most common ATC spindle families in CNC router and machining center applications.
Water-Cooled Duty Range
Every model in this range uses water cooling, providing consistent thermal management for continuous-duty routing and machining operations.
Two Voltage Paths
The range includes 220V and 380V variants so buyers match machine power and VFD planning quickly.
Platform-Based Selection
Basic, Model A, Model B, and Model C groupings make it easier to narrow by body size, rigidity, and intended machining profile.
Application fit
Matched to your machine, material, and duty cycle
These application profiles indicate which spindle family and platform tier suits each machining environment — from light-duty wood routing to continuous metal cutting.
CNC Router
Wood, plastic, and composite machining with automatic tool change for multi-bit workflows.
Machining Center
Metal milling and drilling operations requiring high rigidity and precision tool clamping.
Engraving
Fine-detail engraving on metals, stone, and acrylic with high-speed ATC spindles.

Selection FAQ
Common questions before requesting a quote
Answers covering interface compatibility, cooling requirements, voltage configuration, and customization scope for the BT30 and HSK40E spindle range.
How do I choose between BT30 and HSK40E spindle interfaces for my machine?
The correct interface is determined by speed and material requirements. BT30 spindles use a robust, high-rigidity taper suited to heavy-duty material removal, steel/aluminum milling, and standard production routing. HSK40E is a lightweight, high-speed interface engineered for high-precision, fine-finish machining and high-RPM operations (up to 24,000+ RPM). Our engineering team reviews gantry weight and workpiece specs to recommend the matching interface.
What electrical voltages and VFD configurations do you support?
Our ATC spindles support standard industrial voltages, including single/three-phase 220V and three-phase 380V configurations to match global grid requirements. For controlled integration, we supply your spindle pre-paired and pre-programmed with a matched Variable Frequency Drive (VFD). Please share your workshop’s voltage and control system setup during the inquiry, and we will configure the matching electrical package.
Why do these ATC spindles use liquid cooling, and what setup is required?
All models in this series utilize closed-loop liquid cooling. Compared with air cooling, liquid cooling provides stable thermal dissipation for continuous-duty routing. This keeps the spindle’s core temperature within safe operating limits, protects the high-precision ceramic bearings, and supports motor service life during heavy-duty routing. The system is designed to pair with standard industrial water chillers (such as CW-3000 or CW-5000), available directly with your order.
Do you offer custom ATC spindle manufacturing or OEM options?
Yes. We work closely with CNC machine OEMs and system integrators. While our standard catalog covers multiple versatile models, we customize mounting flanges, runout tolerance thresholds, encoder types, and integration sensors for volume orders. Contact our technical sales desk with your custom parameters or blueprints, and we will evaluate the feasibility within 24 hours.
How is spindle precision and balancing verified before shipment?
Each spindle motor is checked with dynamic balancing and an operational test before shipment. The order inspection report lists the measured runout and vibration values for the supplied unit, so buyers confirm the actual values from the delivery documents instead of a generic catalog promise.
