THE ULTIMATE FAQ GUIDE

CNC double column machining center

Q

1. What is a CNC double column machining center?

CNC double column machining center, also called double column CNC milling machine, gantry machining center, double column vertical machining center, is one of the largest CNC machines available.

Its overall structure is a large machining center with double columns and top beam forming a portal structure frame.

There is a cross beam in the middle of the double columns. It is especially suitable for machining large workpieces and workpieces with complex shapes.

Double column machining center is a kind of vertical machining center, which is suitable for any industry and can be expanded with 4 or 5 axes.

Q

2. What are the types of CNC double column machining center?

Usually CNC double column machining center consists of X, Y, Z three axes, its structure and vertical machining center for the spindle vertical downward movement.

There are several types of CNC double column machining centers according to the structure as follows:

  • Fixed beam type (fixed beam, table movement/rotation)
  • Moving beam type (cross beam moves up and down, table moves back and forth)
  • Moving column type (table fixed, gantry moving)
  • Bridge type (table fixed, gantry moving)

Multiple types of gantry machining centers in the above composite forms. The processing characteristics, capabilities, and product processing applications are not exactly the same.

According to the number of axes can be divided into the following types:

  • 3 axis CNC double column machining center
  • 4 axis CNC double column machining center
  • 5 axis CNC double column machining center
Q

3. How does a CNC double column machining center work?

Double column machining centers work in the same way as vertical machining centers.

Its main function is milling.

In practice, vertical machining centers are unable to machine large parts and molds due to size limitations.

The double column machining center breaks this limitation.

By writing the program in G code and importing it into CNC controller, the part is placed on the table, and the double column machining center realizes the manufacturing of parts and molds by moving the X, Y and Z axes and rotating the spindle.

Double column machining center can also be equipped with a rotary table to achieve 4 axis or 5 axis machining.

Double column machining centers are large machines, designed for machining large parts.

It is mainly used in heavy industries, such as aircraft, automobile, ship and other heavy industries.

Mainly processing large and complex shape of the workpiece, such as processing the aircraft beam, frame and some parts of the large machinery.

In a word, double column machining center is a large machine tool designed for processing large and complex parts, which is suitable for various industries, especially for large parts industry.

Q

4. What is a fixed beam CNC double column machining center?

Fixed beam type double column machining center is the most common double column machining center in the market.

Its structure is simple and easy to understand, mainly consists of table, bed, column, beam, saddle, ram and other components.

The table moves left and right on the bed as X axis, the ram and saddle move forward and backward along the guide rail as Y axis, and the ram moves up and down along the vertical direction as Z axis.

Q

5. What is moving beam type double column machining center?

Moving beam type double column machining center is also common in the market, and its structure is more complicated than fixed beam type gantry machining center.

It also consists of bed, table, column, beam, saddle, ram and other mechanical parts.

The table is rectangular in the bed to do left and right movement for the X axis, crossrail segment up and down movement for the Z axis, ram and saddle along the crossrail horizontal direction back and forth movement for the Y axis.

The moving beam type double column machining center is suitable for machining higher height parts.

Q

6. What is a moving column type double column machining center?

The structure of moving column type double column machining center is more complicated, rare in the market and expensive.

The two columns of this double column machining center are movable, the two columns move to the left and right at the same time for X axis, its table is fixed, the ram and saddle move forward and backward along the horizontal direction of the beam guide for Y axis, and the ram on the saddle moves up and down along the vertical direction for Z-axis.

Q

7. What is a bridge type double column machining center?

The machining center where the table is fixed and the cross beam moves on two overhead bridges is the bridge type double column machining center.

Some people think that bridge type double column machining center is a kind of moving beam double column machining center, which is not a correct understanding.

The moving beam gantry refers to the structure where the crossbeams move on the columns. In fact, the bridge type gantry machining center is an upgrade of the moving column type gantry machining center.

Q

8. What are the benefits of CNC double column machining center?

If you have never used a CNC double column machining center before, you will find the following benefits when you use it for the first time:

  • Large size products, parts and molds can be machined.
  • The workpiece clamping is more convenient than vertical machining center.
  • High milling capacity
  • It is also more advantageous for machining complex shapes of workpieces.

Double column machining center is a must for large products, but of course it is expensive.

Q

9. What is the price of CNC double column machining center?

There are many types and specifications of CNC double column machining centers, and the price varies greatly between different types and specifications.

There are many factors that affect the price of a double column machining center, as follows.

  • Brand
  • Structure type
  • Specification
  • CNC controller
  • Manufacturing process
  • Country of manufacturer
  • Core Component Brand
  • Shipping Cost
  • Tariff Costs

All these factors are closely related to the price of double column machining center.

If you want to buy a CNC double column machining center in China, I can give you an approximate price range, as follows:

  • 3 axis CNC double column machining center price $50,000-$150,000
  • 4 axis CNC double column machining center price $60,000-$170,000

The above only lists the price range of 3 axis, 4 axis and 5 axis double column machining center, the price varies greatly due to different specifications.

In addition, the price of moving beam type, moving column type, bridge type double column machining center is more different. The price of different types of double column machining centers may vary by $50,000.

 

Q

10. How to choose CNC double column machining center?

A two-column machining center is a long-term and expensive investment.

How to choose the right double-column machining center?

This is a good question.

We have summarized some key considerations on how to choose the right vertical machining center as follows.

  • What is the purpose of the machine? (material to be machined)
  • How many axes are required? (3 axis, 4 axis, 5 axis)
  • What is the required machine size (depending on the part being machined)?
  • Do you need an automatic tool changer?
  • Do you need a universal milling head?
  • Do you need a Spindle center water outlet system?
  • Do you need an automatic probing system?
  • What type of spindle, power and speed is required?
  • What level of machining accuracy is required?
  • What is your price budget?
  • What CNC controller do you specialize in?

I believe that after understanding the above questions, you should have an answer for how to choose the right double-column machining center.
