10 Reasons Twin Boring is Better for Holemaking than Helical ...

Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option that’s sure to deliver the results you’re looking for and then some. 

Goto LECN to know more.

Boring heads like the SW 319 twin cutter provide an alternative to helical interpolation milling that’s proven to add far more value to hole-making operations. 

1. In a roughing operation, the tool is set once with no need for presetting after an insert change. Helical interpolation will require length setting and runout checks every time an end mill needs to be replaced.
2. A twin rougher has fixed tool lengths and diameter scale, requiring no special equipment for set up.
3. Perfect roundness is easier to achieve more consistently.
4. A consistent inline feed requires less programming than the stepped removal required of an end mill or multiple boring bars.
5. The plunging motion results in axial load as opposed to radial during helical interpolation, preserving the machine and spindle components.
6. Especially in long-reach applications, the superior load balance in the cut makes for more reliable and consistent performance than a mill with sideload.
7. Milling tools can have multiple inserts per flute, while the twin cutter only requires two, lessening consumable cost and replacement time.
8. Chips are smaller, broken cleanly and open spaces between insert holders allow perfect chip formation and evacuation. 
9. Switching the mounting locations of the 319 insert holders allows for performing balanced- or stepped-cutting without additional accessories or adjustments.
10. By swapping insert holder types, shanks and boring tool bodies can be used for other operations such as chamfering and back facing.

Watch application manager, Matt Tegelman, demonstrate how simple it is to adjust a twin boring head for stepped or balanced cutting.

A&L Machine discovered many of these benefits firsthand. “The results were immediate and undeniable,” Allen Dvoracek, A&L president, said. “We’re getting better parts off the machine sooner, allowing us to get to the next job ahead of schedule.“ Read more about A&L’s experience here.

A cnc wood router is a powerful tool that make a massive progress for small-to-mid-size businesses by helping improve woodworking efficiency, quality, and productivity. It is easy to see why so many shops who looking to start or expand business look into purchasing a CNC router.

But with so many options on the cnc market today, it is difficult to know where we can start and what should we consider when we researching cnc routers. Here, from a professional production perspective, we provide some of the top aspects you need to know to ensure you get a cnc machine that provide the best service to your current and future works-while also staying within your budget. Let's take a look.

Features and Capabilities

• Have a clear understanding of your own production needs

Before you buy your cnc wood router, the first question you should ask yourself is: What does my shop really need out of a cnc router? How big is my studio? How large is my team? What type of parts or projects we planning to produce? What material that I mainly use? These questions will help you accurately find the right cnc wood router models that suit your needs.

Maybe your workshop is short of manpower and need a more automated ATC CNC router with top-end vacuum technology to save labor; maybe improving the production environment is necessary for you so that you need to have a cnc router with powerful vacuum cleaner; maybe you need to improve production efficiency and need a multi-head cnc router.  If you frequently work with camber shapes in production, or your project is required to process three sides on the basis of one-time workpiece clamping, a 4-axis CNC router would be the most suitable choice. If you plan to work on both wood panels, square or cylinder wood, a CNC router with a rotary add-on may be the right tool for you. If you're primely working on materials like marble, granite, or aluminum and copper, please go with a stone cnc router. If your project requires machining of 5 sides in one setup, consider using a 5-axis CNC router for complex projects. Whatever the case may be, understanding your specific goals is a key first step in narrowing down your purchasing decision.

• Machining Size

Machine size is another important aspect you need to consider during searing a cnc router, especially for the shops who has limited space. If you accidentally buy an oversized machine which is too big for your space, you’ll either have to sacrifice other elements of the shop or spend time and money expanding your space.

Typical sizes for CNC routers are 2'x3', 4'x8' and 5'x10'. EaglecTec CNC also offers customized machines for specific needs. We need to select a bed size that meets production needs and fits our shop space.

• Transmission system

When searching cnc router drive systems on google, you will find two types: one is rolling ball-screw and the other is rack and pinion. For larger and higher tech cnc routers, such as 5 axis cnc router, cnc routers for large form mold making, ball screw transmission is the better choice to produce better parts by operating in a way that is more precise. But this is not to say that rack and pinion is not a good option. Quite the opposite, in fact.

For general wood cnc machine, rack and pinion is a cost-effective transmission method that has been tested countless times. EagleTec general cnc router models are driven by XY-axis rack- and-pinion systems and Z axis ball-screw technology. EagleTec technical parts try their best to increase the performance and lifespan of the gear while reducing maintenance in the process of designing and producing of our cnc routers.

• Drive motor

Except the transmission system we need to consider, the other system we should keep in mind when shopping a cnc router is machine drive system. There are also two primary types used in cnc routers: stepper motor and servo motor.

Stepper motors are usually used on small cnc routers that do not need high speed or torque. The stepper motors run open-loop (means the driver only send the command to the motor but doesn’t receive feedback from it), this one-way communication can help to remove the cost of adding an encoder. The step motor keeps working and will not stop until it is broken. A cnc router with stepper motors is very suitable for massive and repetitive cutting and engraving work.

Servo motors come into paly when we need a big cnc router which requires more power to work effectively. And they are best for atc cnc machine which requires improved positioning precision and resolution. They run faster than stepper motors. Servo motors run closed-loop(connect with encoder, the driver receives feedback from the motor after sending command to it).

At the same time, we will equip a planetary reducer on EagleTec high level cnc router with servo motor to improve speed and accuracy with less maintenance.

Machine Budget

This one is obvious. If you cannot afford to add a cnc router to your shop, it means this is not a proper time to get it. If you want to buy a high cost-effective cnc router with certain budget, a reliable Chinese made machine is your best choice.

Don't rush to refute if you have different opinions on Chinese made machine.

Pls note that what I say is reliable cnc router manufacturer, not the one you purchased at significantly lower prices than normal. If you find two cnc routers which look the same by pictures but their price has huge differences, do not past the expensive supplier first. Try to know more details that you can not see in a machine picture. And try to search their machine and service feedback. Then you will know why same machine has such different price.

Ease of Use

Depending on your level of wood working experience and cnc expertise, ease of use may also be a key factor in choosing a CNC router.

If You Have Plan to Import a CNC Router from China but Have No Import Experience, What Should You Do?

First, contact Jinan EagleTec to make decision about which machine model you want. (our sales and technicians also will recommend you proper machine model according to your work).

Second, pay deposit and factory start manufacturing. (Pay attention to the voltage you need)

The company is the world’s best High Efficiency Double Head CNC Lathe supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Third, Machine production is completed and the customer pays the final payment.

During second and third process, you can find a local freight forwarder or customs clearance agent. They can help you handle with all the importing issues, such as shipping cost and tariffs.

Also, you can arrange machine manufacture responsible for sea shipping and you only find an agent to do with importing issues.

Forth, Sea shipping.

Fifth, the machine arrived the port and agent deal with importing issues.

Sixth, Find a proper truck according to machine size and bring it home.

Finally, contact machine suppliers to learn to how to install and use your cnc router.

Then you can immerse yourself in cnc zone.
