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.

Which one is better?

Saturday, June 12th, 2010

Lots of people have made extremely impressive machines with ACME screws and stepper motors. These components are perfectly suited for hobby and light industrial cnc machines, and in general offer a much better value than ballscrews for people interested in doing cutting tasks that don’t require +/-0.001″ accuracies or better.

While ballscrews are more efficient, high pitch ACME also runs smoothly and does a great job of converting rotational motion to linear travel. Furthermore, unless you get a double ball nut or a ball nut with oversized balls loaded in it for your ballscrew, as well as angular contact end bearings for them ($$$), it’s possible to get worse backlash in a ballscrew than in a low cost anti-backlash ACME setup.

As to stepper motors of cnc router, these are proven technology that are easy to setup, and can offer truly impressive performance. If one has unlimited funds, then by all means, go with servo drives and planetary gearheads, and have fun tuning PID loops. It is fun — I used to do this for high speed pick and place robots. But for a beginner or anyone on a budget, steppers can offer an excellent performance/$ ratio, especially when coupled with a high end drive like the G540, and are quite easy to set up.

But in Redsail, you can find different types, ball screws, square linear guide ways, etc. We also have servo motor for our woodworking router.

How to choose CNC router

Tuesday, June 16th, 2009

The first thing about a CNC router that really stands out from a CNC mill is the scale. A CNC router can have a machinable area of 60″ X 216″ X 8″. While the CNC router is not suited for cutting ferrous materials, it excels at cutting composite prototyping boards, plastics, carbon fiber and even non-ferrous metals with the proper accessories.

A CNC router can allow you to do larger scale mold masters and cavities, and in turn, service markets currently being ignored by most mold and pattern shops. Applications have included mold masters for 1/5 scale RC helicopter FRP molds, 6′ x 10′ centerboard masters for sailboats, antique grille masters for sand casting and various automotive application molds and masters for vacuum forming. The versatility of a CNC router is amazing as it excels at cutting smaller molds and masters with reliable tolerances in the .003 to .006″ range.

With the addition of quality CAD/CAM software, small and start-up shops can create a viable operation with the combination of thermoforming equipment and a CNC router. The CNC machines the appropriate plug or cavity, which is then sent to the thermoforming machine. The thermoformed part is then returned to the CNC and placed in a vacuum fixture or frame to hold the part. The CNC then accurately trims the circumference of the part, in addition to machining or drilling features necessary on the finished part.

This versatility allows smaller shops to be competitive with a minimal investment. Existing shops can use their CNC router to expand their business by catering to larger scale components for the thermoforming, FRP, sand casting, and even prototyping markets. The CNC router also can be used to create fixtures, packaging and a host of other parts to be used in the shop itself.

When choosing a CNC router for your business, the overall build quality of the machine is only one aspect to consider. Many CNC routers quickly become obsolete with costly upgrade paths or expensive replacement parts as the years begin to take their toll on the machine. Do your research, visit local shops that have the brand of router you are interested in and ask lots of questions.

Suction systems of CNC router

Tuesday, June 16th, 2009

Suction Systems

The wood router typically holds wood with suction through the table or pods that raise the work above the table. This type of hold-down is used for components which require edge profiling (or undercutting), are manufactured from solid wood or where greater flexibility in production is required. This type of bed requires less extraction with greater absolute vacuum.

A second type hold down requires a “spoil board” or “cull sheets” to the work. This allows vacuum suction through the low density table and allows the placement of parts anywhere on the table. These types of tables are typically used for nest-based manufacture (NBM) where multiple components are routed from a single sheet. This type of manufacturing precludes edge drilling or undercut edge work on components. However most industrial sized machines similar to the S series CNC by Vortech Routers or C.R. Onsrud Panel Pro allows the use of spoil boards or a pod system that elevates the work piece to accommodate edge work.

Vacuum pumps are required with both types of tables where volume and “strength” are determined based on the types of materials being cut.

Redsail M series CNC router has such a function which will fits many customer’s requirements.

At the same time, our CNC wood router also has Oil lubrication system which can smooth the rail and block for rail.

What is CNC wood router?

Tuesday, June 16th, 2009

Redsail M series CNC router is called CNC wood router. So what is CNC wood router? Now let’s  share some information about it:

A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill  with the following differences:

  • The wood router typically spins  faster — with a range of 13000 to 24,000 RPM
  • It typically uses smaller tools — typical shank size 20 mm or at most 25 mm.
  • It typically uses smaller toolholders MK2 (Morse taper #2 - on older machines),ISO-30, HSK-63 or the tools just get held in a collet tool holder affixed directly to the spindle nose. ISO-30 and HSK-63 are rapid-change toolholding systems. HSK-63 has begun to supplant the ISO-30 as the rapid change standard in recent years.

A wood router is controlled in the same way as a metal mill, but there is a lot of CAM software like Artcam, Mastercam, and Featurecam specifically for wood routers.

Wood with different grain must be approached with unique strategies, and wood CAM software is less likely to need to have hog-out strategies than the metal ones. Wood routers are frequently used to machine other soft materials such as plastics at high speed.

Typical three-axis CNC wood routers are generally much bigger than their metal shop counterparts. 5′ x 5′, 4′ x 8′, and 5′ x 10′ are typical bed sizes for wood routers. But can be built to accommodate very large sizes up to, but not limited to 12′ x 100′. Most table routers use a three motor drive system (xyz) utilizing either servo or stepper motors that drive the router motor via a gantry system. The gantry system isolates the XYZ movement in the top part of the machine with a stationary table holding the workpiece. Many CNC metal mills have the cutter motor moving on the Z axis, and a table which moves in X and Y for added stability.

Many wood routers can run at machining speeds of 25 metres/min (linear) or faster with a few machines such as the Anderson capable of 40 metres/min, Onsrud capable of 86 metres/min.

This is a short introduction about CNC wood router. Next time we will share information about its spare parts.
