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

The CNC machining center refers toautomated 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, allowing complete 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:

• Work area, where the immediate reformation of the workpiece takes place.
• Store storage tools with automated loading process.
• Rotary table for cutting workpieces of long dimensions.
• Mechanisms of loading-unloading of blanks, products.

The technological capabilities of the plants allowto carry out quick adjustment for another 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.

Machining center with CNC is expedientUse in industries where frequent changes in the type of technology are required. For cutting metal, several similar plants 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 workpieces.

Mechanical structure

Machining center with CNC is based on the frame,resistant to vibration 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 together with a detail, or on it the cutting tool is fastened.
• Pneumatic or mechanical clamps on the table. This is how the dimensional workpieces are fixed: sheets of plywood, plastic.

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

Installation requirements

CNC milling machining center is selectedunder the task of production. The maximum dimensions of the parts are taken into account, which affects the length of the screw axis of the coordinate axes. Manufacturers lay in the development of the possibility of updating the current version of the machine. 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 parameterto improve performance. 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 the accuracy in the dimensions of the edges, threads and grooves.

What are automated installations capable of?

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

• cylindrical movements;
• conical;
• shaped processing;
• drilling holes;
• facing.

In the turning group, the tool moves through thecoordinate 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 a cooling unit for cooling the cutting zone, removing chips. Specialized clamps are recommended to choose for a single production of overall dimensions.
