ER32 6kW Square Air-Cooled CNC Spindle for Sale

This 6kW ER32 CNC spindle motor is intended for CNC router manufacturers, production workshops, machinery repair companies and wholesalers sourcing a higher-power square-body spindle. The ER32 interface supports compatible tooling when the correct collet size and cutter shank are selected.

Typical application materials include wood, MDF, plywood, acrylic, PVC and machinable plastics. Selected machining operations on aluminum and brass may also be feasible on appropriately rigid machines with suitable tool geometry, chip evacuation, feed and speed settings.

Compared with a water-cooled spindle, the air-cooled body eliminates a separate coolant pump, tank and water circuit. Airflow and dust management remain important. The item is a motor-only listing; a VFD is required but is not included in its published standard package.

ER32 6kW Square Air-Cooled Spindle Motor Features

ER32 Tool-Holding System

An ER32 collet interface is suitable for compatible CNC cutters. The shank sizes actually held depend on the specific collets, not on the ER32 interface alone.

6kW Power for CNC Equipment

The rated 6kW output supports selection for production-oriented CNC routing machines where the frame, axis load capacity and cutter parameters are appropriate.

380V Electrical Configuration

The published model is rated at 380V and 12A. Specify your power supply and motor requirements before choosing the VFD; do not assume that a 220V variant is included in this listing.

300Hz Inverter-Based Speed Control

The published 300Hz and 10,000–18,000 RPM values require appropriate VFD parameterization and adherence to the motor nameplate. A spindle motor does not independently provide CNC/PLC speed control.

Square Motor Body for Machine Mounting

The square housing can be incorporated into compatible mounting designs. Check the installation hole pattern and overall body clearance against the machine.

Air Cooling Without a Separate Water Circuit

The motor uses air cooling, avoiding an external water pump and coolant hoses. Preserve adequate air circulation and manage dust accumulation.

Four-Bearing Configuration

The product title describes four bearings. For precision-sensitive orders, confirm the bearing construction and specified inspection procedure for the selected model.

Professional CNC Controller Integration

Depending on the chosen inverter, start/stop and speed control can be integrated with a compatible CNC controller or PLC. Verify signal interfaces and electrical protection before commissioning.

Frequently Asked Questions About the ER32 6kW CNC Spindle

What is the Zhong Hua Jiang ER32 6kW square air-cooled spindle used for?

It is intended for compatible CNC routers, engraving machines and suitable milling applications that require a 6kW square-body spindle and ER32 tooling.

Is this a standalone 6kW spindle motor or a spindle-and-VFD kit?

It is a spindle motor listing. A matching external VFD is needed for operation but is not listed in the standard contents of this motor-only package.

What voltage does this ER32 6kW spindle motor require?

The published version is 380V. Confirm the exact motor nameplate and power supply configuration before ordering or programming a VFD.

What is the rated motor current?

The published model lists 12A. Use the current printed on the supplied motor nameplate when selecting the VFD and protection devices.

What are the published operating speed and frequency?

The listing specifies 10,000–18,000 RPM and 300Hz. The motor must be operated within the limits confirmed for the supplied version.

Which VFD is suitable for the 6kW ER32 air-cooled spindle?

Choose an inverter compatible with the motor’s 380V rating, 6kW output, 12A current and 300Hz specification, together with your available power supply and CNC controller interface.

Does this square spindle motor include a VFD?

No VFD appears in the published standard motor package. Ask for a separate inverter quotation if a combined solution is needed.

What collet system does this CNC spindle use?

The spindle uses an ER32 collet interface. Select an ER32 collet that matches the actual shank diameter of your cutting tool.

Are 6mm and 12.7mm ER32 collets included?

The original listing states ER32-6/12.7mm but does not clearly identify the exact number of each size. Confirm the packing configuration for your order.

What are the overall dimensions of the 6kW spindle?

The main product panel lists 430 × 122 × 110mm. Request a dimensioned mounting drawing; a shorter length appears elsewhere in the original description.

How much does the ER32 6kW motor weigh?

The published spindle weight is 15.3kg. Check the packed gross weight separately for shipping and machine-load calculations.

Is this 6kW spindle suitable for existing CNC router upgrades?

Potentially, provided the machine accommodates the motor dimensions and weight and has compatible mounting hardware, electrical power, inverter controls and ventilation.

What type of bearings does this motor use?

The product name describes a four-bearing spindle, while the original detail discusses steel bearings. Confirm the exact bearing design in the technical quotation.

What runout tolerance can be guaranteed?

The original sales material contains different runout examples. For precision purchasing, specify the measurement position, collet, tool setup and required acceptance tolerance.

Can this spindle be used for MDF, plywood and solid wood?

These are among the described woodworking applications. Choose cutters and operating parameters suited to the material, machine rigidity and desired finish.

Can this 6kW spindle machine aluminum or brass?

Suitable engraving or light milling may be possible on compatible soft metals when cutter geometry, chip management, feed, speed and machine stiffness are appropriate.

What maintenance does an air-cooled spindle require?

No separate water-cooling system is necessary. Keep cooling passages clear, maintain ventilation and perform maintenance according to the motor and drive instructions.

Can the spindle be controlled by GRBL or a PLC?

Control depends on the selected VFD and the controller’s available start/stop and speed-command interfaces. Confirm wiring and configuration before installation.

What comes with the published standard package?

The standard list includes one 6kW square air-cooled spindle motor, a stated ER32-6/12.7mm collet specification and two wrenches. Verify the exact accessory quantities in the quotation.

Can you supply the spindle with a matched inverter?

The product information describes VFD matching as an option to discuss. Provide the destination electrical supply and controller requirements when requesting a combined quotation.

Is OEM branding or wiring customization available?

The product page invites discussions about OEM and machine-building needs. Provide your branding, voltage, cabling and mounting requirements for a feasibility assessment.

What is the minimum order quantity for wholesale buyers?

The original listing mentions trial orders and bulk purchases but does not establish a fixed MOQ. Request the quantity terms for your selected configuration.

What lead time is listed for the 6kW spindle?

The original page gives 3–7 working days for standard units and 10–20 days for custom or bulk orders. Obtain a confirmed production and dispatch schedule before placing an order.

What warranty and technical support are listed?

The original listing mentions a 12-month warranty and technical support for electrical installation and VFD setup. Confirm applicable terms in the sales agreement.
