HQD 1.5KW Air Cooled Spindle with Flange 220V 5.6A 300Hz 18000rpm ER20A (Model GDF46-18Z1.5)

The HQD 1.5kW Air Cooled Spindle with Flange is designed for CNC routers, engraving machines, and compatible machining systems that require a stronger spindle for routing, engraving, milling, trimming, and light cutting applications. With 1.5kW power, 18,000rpm rated speed, and ER20A tool holding system, it is suitable for users who need more cutting capacity than smaller desktop spindle options.

This model features an air-cooled design, reducing the need for a separate water pump, water tank, and coolant circulation setup. The integrated flange design also provides a practical mounting method for compatible CNC machine structures.

With 220V input, 300Hz rated frequency, and model reference GDF46-18Z/1.5, this spindle should be used with a suitable VFD/inverter correctly matched and configured to the spindle specifications.

1.5kW Power for CNC Machining

The 1.5kW power rating makes this spindle suitable for a wide range of CNC workshop tasks. It can be used for routing, carving, engraving, profile cutting, trimming, and light milling work depending on the CNC machine, cutter size, material, feed rate, and cutting depth.

It is a practical spindle choice for users upgrading from smaller spindle systems and looking for improved machining capacity.

Air Cooled Design

The air-cooled structure helps dissipate heat during operation without requiring water circulation. This keeps the machine setup simpler and reduces maintenance related to pumps, hoses, coolant tanks, and water leakage.

Good airflow around the spindle should be maintained during operation to support stable cooling and long-term reliability.

Flange Mounting Structure

The flange design provides a fixed mounting style for compatible CNC machines. This can help improve installation stability when the machine frame and spindle mount are designed for this type of spindle body.

Before purchase or installation, confirm the flange mounting dimensions and machine compatibility.

18000rpm High-Speed Operation

With a rated speed of 18,000rpm, this spindle is suitable for many CNC cutting and engraving applications. It can be used with suitable router bits, end mills, engraving tools, and other compatible cutters for wood, plastic, acrylic, and similar machinable materials.

Actual cutting quality depends on the selected tool, material, spindle speed, feed rate, depth of cut, machine rigidity, and workholding.

ER20A Tool Holding System

The ER20A tool holding system allows the spindle to work with compatible ER20 collets and CNC cutting tools. ER20 collets support a useful range of tool shank sizes, making this spindle suitable for different routing, engraving, and milling jobs.

Always use the correct collet size for the tool shank and make sure the cutter is securely tightened before operation.
