Frequently Asked Questions

Should I choose a water-cooled or an air-cooled spindle?
Water-cooled spindles run quieter and hold a steadier temperature during long continuous work, but they need a pump, water tank and tubing. Air-cooled spindles are simpler to install because they need no coolant loop, but they are louder. Pick water cooling for long, heavy cutting and air cooling for simple setups.
What are the specifications of the JST Water Cooled Spindle?
Power, voltage, speed range and collet type for the JST Water Cooled Spindle are listed in the specification table on this page. Send us your machine model and mounting size, and our team will confirm that it fits before you order.
What do I need to run a CNC spindle motor?
You need a variable frequency drive (VFD) that matches the spindle power, voltage and frequency range, plus a controller that sends the speed signal. Water-cooled spindles also need a pump, tank and tubing. Check the nameplate on the spindle and send us your model so we can help you match the drive.
How do I choose spindle power and collet size?
Choose power by the material and the depth of cut: light power is enough for wood, plastic and engraving, while aluminum and deeper cuts need more power. Choose the collet type, such as ER11, ER16 or ER20, by the tool shank diameters you use. Tell us your material and tools and we will recommend a model.
What coolant should I use in a water-cooled spindle?
Use clean circulating water or the coolant recommended for the spindle, and add antifreeze in cold climates. Always start the pump before the spindle and never run the spindle without circulation. Check the water level and tubing regularly.
What is the minimum order quantity, and can I order samples?
The minimum order quantity is 1 piece, and sample orders are welcome. You can test fit and quality on your own machine before placing a larger order. Send us your model, size and application and our team will prepare a quotation.
How long does delivery take, and which shipping methods do you support?
Delivery usually takes 3 to 7 days after payment, depending on the model and your requirements. We ship by DHL and other express services for samples and small orders, and by sea freight for larger shipments. Payment can be made by T/T or PayPal.
What warranty do you offer, and can I get inspection reports?
We provide a 3-year warranty. If a quality problem occurs, we supply replacement spare parts. A machinery test report and an outgoing-inspection video are available on request, so you can verify the product before shipment.
