Product Description 
A true 5-axis machine can allow for continuous 5-axis machining simultaneously. This increases both speed and accuracy when machining the part.
 CNC Vertical Mills generally have a single spindle, automatic tool changer, work table and CNC Control.
 The spindle on a CNC Machining Center can have a wide range of speeds depending on what material is being cut and the depth of cut that is required. Typical spindle speed ranges from 0 to 10,000 RPM. Higher speeds are used for lighter materials including graphite and aluminum among others. Higher speeds can reach 12,000 RPM up to 50,000 RPM and higher.
 The Spindle is loaded with tool holders and cutters to achieve the proper material removal. There are many different styles of tool holders including BT and CAT – which have a conical shape as well as HSK, which uses flanges instead of a taper to lock the holder in place. BT and CAT Holders can come in various sizes including 30, 40 and 50 taper depending on the size of tool the cutter requires. HSK (Hollow taper ShanK) comes in a variety of types – A through F – and sizes from HSK-32 up to HSK-160. HSK is considered a better tool holder for high speed machining as there is more surface contact between the spindle and the holder, reducing vibration and keeping the tool from pulling back into the receiver when cutting at high speeds.

Product Advantages

The advantages of CNC Vertical Milling Machine

1.Tool Changer — A tool changer greatly increases a VMC's productivity by allowing for the automatic, computer-controlled selection of tools for a variety of tasks from rough cutting to fine hole boring. 

2.Coolant System — To keep parts and cutters cool and lubricated, most VMCs employ some sort of recirculating coolant system; which is usually a mix of soluble oil and water but can be a variety of other liquids as well. 3.Chip/Screw Conveyor— To evacuate the chips from the work zone, a variety of chip conveyors and chip augers may be employed to increase productivity and reduce downtime from manually shoveling out waste chips. 

4.Full Covers/Enclosures— These can be added to reduce the splash/splatter caused by milling operations and protect the operators and environment from the machining process. 

5.Rotating Tables — Adding additional Axes to the machine can greatly increase its productivity by turning a simple three-axis machine into a four- or even five-axis system capable of machining complex components with varying surfaces (such as turbine blades). 6.Quick Loading Loaders — Another great addition to significantly increase productivity is the use of shuttle tables or other automatic part loading systems. These can decrease downtime and greatly increase the spindle “ON” time of most VMC systems.

Application Example

This VMC is suitable for mechanical processing and mold making .And it can adapt to the processing
 requirement from rough machining to finish machining .It can also finish many working procedures like milling ,drilling
 ,tapping,boring ,etc.
