Machining center with CNC: distinctive features, purpose, advantages over simple settings

Machining center with CNC refers to automated multi-axis installations. It has several independent control channels. The memory stores information about each stage of the workpiece processing, the position of the support and the cutting tool. The control panel is equipped with a stand-alone PC, which allows full fault diagnosis. Specialized applications make it easier to load process codes for new parts.

What does the management system include?

The CNC machining center has several functional areas:

• Working area, where the immediate re-cutting takes place.
• Store storage tools with automated loading process.
• Turntable for cutting workpieces of long dimensions.
• Mechanisms of loading-unloading of blanks, products.

The technological capabilities of the plants allow for quick adjustment to a different size, material parts. The latest developments are available for 5D processing. The cutting modes are selected by changing the speed of rotation of the spindle unit and feeding axes with cutters.

The CNC machining center is advisable to use in industries where frequent changes in the type of technology are required. For cutting metal, several similar installations are built. Thus, the production of blocks of heads of automobile engines, threading on pipes of various diameters is made. Also, similar goals are pursued when milling wood and plastic billets.

Mechanical structure

The CNC machining center is based on a frame that withstands vibrations and high loads. Movable parts are attached to the base with a hard stop. The following mechanisms are used for workpiece clamping:

• Spindle with grips. Rotates with the workpiece, or a cutting tool is attached to it.
• Pneumatic or mechanical clamps on the table. This is how the dimensional billets are fixed: sheets of plywood, plastic.

The tool spindle is designed for certain purposes with a floating part where the incisors perform inclined movements with respect to the surface to be treated.

Installation requirements

The CNC milling machining center is selected for production purposes. The maximum dimensions of the parts are taken into account, which affects the length of the screw-spindle of the coordinate axes. Manufacturers are putting into development the possibility of updating the current version of machines. The buyer plans future investments to purchase a new installation or upgrade an already purchased version.

The inertia of the controlled axes is an important parameter for increasing productivity. When optimizing the requirements for the speed of manufacturing parts, an important parameter is set-the reliability of rotating assemblies. Automated pulse lubrication of the guides is a necessary element in the design of the machine. The disadvantages of these parameters lead to a decrease in accuracy in the dimensions of the edges, threads and grooves.

What are automated installations capable of?

CNC turning centers are used for the processing of rotating parts. Types of operations:

• Cylindrical movements;
• Conical;
• Shaped processing;
• Drilling holes;
• Facing.

In the turning group, the tool moves along the coordinate system, the part is clamped into the spindle unit. Materials for processing affect the stiffness parameter of the structure. Machining centers perform cutting on the following details:

• Plastic;
• Metal;
• Wooden;
• Composite;
• Organic glass;
• Stone structures.

The additional equipment includes the cooling unit for cooling the cutting zone, removing chips. Specialized clamps are recommended to choose for single production of overall dimensions.
