Spindle Motor JST JGD-80C-2.2 – 2.2 kW / Ø80 mm / Water Cooled

The JGD-80C-2.2 model is a reliable choice for professional and semi-professional CNC machines. With a power output of 2.2 kW and a robust construction, this spindle operates efficiently at high speeds (up to ~24,000 rpm) and uses water cooling for a longer lifespan and stable performance. The Ø80 mm housing and standard ER20 collet make it easily adaptable to a wide range of CNC systems. Suitable for wood, composite materials, and soft metal machining.

Advantages and Strengths:

- Water cooling ensures effective heat dissipation → stable operation at high speeds.

- High power (2.2 kW) and high speed, allowing for precise machining and engraving.

- ER20 collet – supports tools with a larger diameter and provides good rigidity.

- Can process a wide range of materials (wood, plastic, composites), making it versatile for CNC applications.

- Quality bearings → longer lifespan and reduced vibrations.

Important Integration Tips:

- Use a VFD (inverter / variable frequency drive) that supports 220 V and 400 Hz to control the spindle.

- During installation, ensure a suitable circulation loop for the cooling water (pump, radiator, and hoses).

- Periodically check the bearings and spindle temperature, especially during prolonged operation.

- For maximum durability, use a quality collet and do not overload the spindle with tools exceeding the ER20 capacity.
