CNC Vertical Machining Centers Advantages:

Compared with horizontal machining centers (HMC), the height of the vertical CNC machining centers column is limited, and the processing range of the box-type workpiece should be reduced, which is the disadvantage of the vertical machining center.

However, the workpiece clamping and positioning of the vertical machining center is convenient; the movement trajectory of the cutting tool is easy to observe, the debugging program is convenient to check and measure, and the problem can be found in time, and the shutdown processing or modification can be carried out;

the cooling condition is easy to establish, and the cutting fluid can directly reach the cutting tool and the machined surface;

The three coordinate axes are consistent with the Cartesian coordinate system, and the intuitive feeling is consistent with the viewing angle of the pattern, and the chips are easy to remove and fall, so as to avoid scratching the processed surface.

Compared with the corresponding horizontal machining center, the structure is simple, the floor area is small, and the price is lower.

5 things you need to consider when buying a VMC.

1.    the application and workpiece(s) and the needs

Design and construction govern a vertical machining center’s ability to machine parts to tight tolerances with accuracy and repeatability.

No matter it’s for a small toolroom, a workshop, or a production house, there are a lot of factors to consider when it comes to acquiring a vertical machining center (VMC). No. 1 important thing is the application and workpiece(s) and the needs of a workshop’s various departments. We need to choose the appropriate VMC according to the workpiece processing requirements and production volume

2. Structure and Stability

Among the numerous machine tool characteristics to scrutinize before buying a VMC are machine structure and stability. The stability and rigidity of the machine are one of the most important prerequisites to ensure machining accuracy.

3. Accuracy and mass production volume

Without considering the accuracy and repeatability, the machine price is meaningless. We are not encouraging customers to buy very expensive equipment. What we want to emphasize is to buy a VMC with high precision and high mass production capacity with the right money.

So the ability to process parts to a tight tolerance and mass production volume must be considered. That is where a machine’s design and construction come into play. Its ability to achieve the required precision and accuracy, and the number of parts to be machined, will influence the quality of the machine that’s needed and the price it will demand. The higher the accuracy and the larger the number of parts to be produced, the higher the benefit the user can expect.

Because of the characteristics of a V8-frame design, a VMC’s thermal stability can be guaranteed. Just as a sturdy house requires a solid foundation, the same is true for a stable machine tool. Most superior VMC structures are engineered using finite element analysis (FEA) software. It’s not simply the weight of the machine that matters; it’s also its design and the placement of the weight that determines its rigidity and stability.

Some machines are equipped with large ballscrews and a different pitch to enhance accuracy. Laser and ballbar calibration can be used to ensure better part accuracy, but only up to a point. A poorly designed machine will never consistently produce high-accuracy parts.

4. Thermal growth and the component resistance performance

Machine stability is also mainly affected by thermal growth. The high spindle speed (10000rpm) generates heat, as does the ball screw, machine work table, and guideway system.

Also, the faster the machine moves, the more friction, and heat it generates. This heat can significantly change the size and position of machine components, causing the machine to "bigger" or deform, and the position of the spindle or cutting tool to move unpredictably. Because of these unpredicted transitions, one of the biggest challenges with five-axis machining is that the control system cannot always calculate the exact location of the axis pivot point.

To solve the problem caused by heating, coolers are used to cool the ball screws and control the temperature of the spindle and spindle housing. Thermal sensors that measure and automatically counteract machine heating growth are located at key points of the machine. These provisions are especially important in tooling applications where longer processing times and more heating. If not controlled, thermal distortion in the machine can cause unacceptable errors in the shape or dimensions.

High-end machines often use a graduated system on each axis rather than the standard encoder feedback system offered by most VMCs. Anti-backlash systems are often designed into ball screw nuts to improve machine repeatability.

Likewise, certain rail systems are designed for high-speed, low-friction operation to help control thermal growth. Of course, all these special features come at a higher price.

High-performance VMC spindles range in price from $4,000 to $30,000. There's a big difference in design between a $50,000 "value" machine and a $300,000 high-end VMC. That said, if accuracy requirements are not particularly stringent and the number of parts is manageable, a value-for-money machine will suffice.

5. Location: A Firm Foundation

The VMC performance is also greatly affected by the workshop foundation and placement where the machine is put on.

In fact, machining at high rates with rapid axis acceleration should require the machine to be tied down on the firm floor.

Heavy deep cutting on some materials also may cause excessive vibration, requiring the machine to be securely anchored to the firm floor. In some cases, it may be necessary to install a steel-reinforced concrete base that is isolated from the surrounding floor. So we have 4 friendly suggestions for you:

1. The location of the machining center:

It should be far away from vibration sources, direct sunlight and heat radiation should be avoided, and the influence of moisture and airflow should be avoided. If there is a vibration source near the CNC machine tool, an anti-vibration ditch should be set around the machining center. Otherwise, it will directly affect the machining accuracy and stability of the CNC machine tool and will cause poor contact and failure of electronic components, which will affect the reliability of the machining center.

2. Power requirements:

Generally, the machining center is installed in the machining workshop, not only does the ambient temperature change greatly, and the use conditions are poor, but also there are many kinds of electromechanical equipment, resulting in large fluctuations in the power grid. Therefore, the location where the machining center is installed requires strict control of the power supply voltage. The power supply voltage fluctuation must be within the allowable range and remain relatively stable. Otherwise, it will affect the normal work of the CNC system of the machining center.

3. Temperature conditions:

The ambient temperature of the CNC machining center is lower than 30 degrees Celsius, and the relative temperature is less than 80%. Generally speaking, there is an exhaust fan or cooling fan inside the CNC electric control box to keep the electronic components, especially the central processing unit, at a constant temperature or with little change in temperature difference. Excessive temperature and humidity will reduce the life of control system components and lead to more failures. The increase in temperature and humidity, and the increase of dust will cause bonding on the integrated circuit board and cause a short circuit.

4. Use the machining center according to the instructions:

When using the machining center, the user is not allowed to change the parameters set by the setting of these machining center parameters is directly related to the dynamic characteristics of each part of the machining center. Only the gap compensation parameter value can be adjusted according to the actual situation.
