Difference between air cooling and water cooling spindle for CNC router

Thursday, June 16th, 2011

When choosing cnc router, spindle is a big point that customers will ask.

There are two types of spindle for making a cnc router or wood router: air cooling and water cooling. All people knows that air cooling is expensive, while what is the real difference between the two types of spindle?

About air cooling first:

1. air cooling looks professional, nice in appearance. The most famous brand is HSD in Italy.  There are many other manufacturers in other countries, too. Like here, Redsail, China(advertising for ourselves)

2, Its installtion procedure is very simple and easy. It can work well just with air, no need to recycle like water cooling.

3, of course no pollution.

About water cooling:

1, cool the spindle by cycling the water. Its temperature will not be higher than 40 degree, so its cooling result will be better than air cooling(air cooling works by a fan). It can longer the life of the cnc routers.

2, No noise

3,  Its working life is longer than air cooling

4, finally, its cheaper, obviously.

But, there is a not very good point: water needs to recycle, so we needs to use a pipe, and it has possibility for water leaking.

Compare the two spindles, we can find that, if you have lots of money, and wants a nice appearance machine, aircooling will be good choice.

But to be practical, water cooling is also good choice.

It depends on what kind of needs you have, and what budget you have.

How to make PCB —Part 2

Saturday, June 19th, 2010

Last time I showed you how the Redsail min cnc router work on PCB. That is a simple video show. Then lots of friends ask me how can we make it exaclty like what you did in the video?

Actually we need 2 steps except the one with cnc rotuer

1. make your file–those drawings in software Coppercam. We use it, but if you have good kind of software. We will be gald to know it.

2. after making this file well, save it as G-code. Some friends will feel strange, cause normally after making file ready, we need to import it in artcam or type 3 or Ucancam to make toolpath. But for making PCB with Coppercam, the importing is not necessary.

Then you can import the G-code into our cnc router  RS-3636.

P.S: Redsail now make all cnc routers with USB connection. That means, we only make a toolpath in artcam or type 3 or Ucancam then import it into the USB handle controller, then we can control the router with that handle.

If you want to knwo the details about the job, dont hesitate to contact Redsail.

Suggestion for buying a CNC router

Thursday, May 20th, 2010

When deciding on purchasing a cnc router, take into account both the capacity (bit shank) and size (Horsepower) when making your decision. A router with 1 HP or less should be just fine for crafts, hobbies, models, etc. while a router with 1 3/4 HP or more and 1/2 inch bit shank capacity will be needed on professional projects involving work with hardwoods or shaping/forming pieces in a router table. The added power will allow for deeper cuts and completing cuts in 1 try. A lightweight router with plastic housing should be fine for light use but consider metal housing for more professional woodworking. Modern routers have electronic features like the electronic variable speed control which should assist you in making more precise cuts. The EVS has a “soft start” feature which users say is ideal since it speeds up the motor gradually. Many plunge routers already have this feature and more and more fixed-base routers are getting it as well. If you do inlay work or dovetails and need precision cutting depths, then make sure the model you choose comes with a fine adjustment control. A “self releasing” collet (holds the bit) should prevent stuck bits and are usually found in higher quality routers.

You can purchase many routers at Redsail and you can read customer reviews and get feedback on the advantages and disadvantages of each model. Of course going into Lowes or Home Depot to actually touch the levers and see them in action is priceless research as well.
