CNC Router Machine Catalogue 2025.pdf
Designed for production CNC routers, this spindle uses an ISO30 automatic toolholder connection to support repeatable tool exchange as part of an integrated ATC machine. It is appropriate for machine builders specifying multiple routing, drilling, profiling and engraving tools across a programmed production cycle.
The 9kW motor and high-speed operating range can be considered for woodworking, MDF panels, furniture components, signs, acrylic and selected nonferrous materials. Actual capability depends on the cutter, workholding, spindle torque curve, feed, chip evacuation and the overall rigidity of the CNC machine.
The air-cooled motor does not need a spindle water-circulation loop. It still requires unobstructed cooling airflow, appropriate dust management and periodic inspection. The automatic tool-release system is separate from the motor cooling system and may require compressed air and machine-side interlocks.
This listing describes the spindle motor rather than a complete ATC conversion package. Toolholders, pull studs, pneumatic hardware, sensors, control wiring and a matched VFD must be confirmed in the quotation before an OEM installation or retrofit.

ISO30 identifies the automatic tool-change spindle taper/interface. ER32 refers to a collet system that may be incorporated into a compatible toolholder. They are not equivalent spindle connections. The product listing mentions both; confirm the intended toolholder style, retention knob, collet sizes and included components when ordering.
The listing references 400Hz and 800Hz as well as 10,000–24,000 RPM. These specifications should not be treated as interchangeable operating settings. Select a drive with suitable output current, voltage and frequency range for the confirmed motor winding and nameplate. Have a qualified integrator confirm earthing, electrical protection and motor parameters before operation.
For an OEM installation or spindle replacement, request the mechanical drawing, mounting interface, spindle nose/toolholder details, tool-release air requirements, tool clamp/unclamp signals, sensor interfaces, cooling clearance, VFD settings and spindle inspection criteria. These values are not specified in the published overview.
Request Detailed Drawings and VFD Matching
An automatic tool changer supports multi-operation machining of cabinet panels, furniture parts, doors, solid-wood profiles and MDF components. Compatible cutters can be selected through the CNC program to reduce manual changes between routing, drilling and finishing tasks.
The spindle can be evaluated for plastic routing, acrylic shaping, sign components and contour cutting, subject to suitable cutters, chip removal, thermal control and feed-speed selection.
Selected light milling and engraving tasks on aluminum or brass may be feasible when the machine frame, fixturing, chip control, tool geometry and spindle torque characteristics are suitable. Material compatibility does not imply unrestricted heavy-metal cutting.
The ISO30 interface is designed for use with an automatic toolholder exchange system. Correct operation depends on compatible holders and retention hardware, pneumatic release actuation, CNC command logic and machine interlocks. A spindle on its own does not provide a complete tool-changing system.
The published 9kW power rating and speed range of 10,000–24,000 RPM support evaluation for multi-tool routing and engraving workflows. The manufacturer lists a 3.58 Nm torque figure; request the torque-speed curve and rating conditions for machining calculations rather than assuming this torque is available at every RPM.
The integrated air-cooled arrangement avoids a separate spindle water pump, reservoir and circulation tubing. Cooling air must remain unobstructed, and dust extraction should protect both the machined part and the spindle ventilation path.
The existing product information describes four angular-contact bearings arranged as 7008 × 2 and 7006 × 2 and refers to ceramic bearings. Confirm the bearing material and assembly for the exact ordered variant, together with any available spindle test documentation.
The published options show 220V at 32A and 380V at 20A. These are motor/drive configuration references, not permission to connect the spindle directly to either mains supply. Verify the motor winding, output phase, cable routing, machine grounding and appropriate VFD parameters for each order.
CNC machine builders should review spindle mass, bracket geometry, Z-axis payload, cutting force, toolholder clearance, dust management and available machine controls. Share the machine drawing and required tool-change cycle with Zhong Hua Jiang when requesting a matched spindle configuration.
