Structural characteristics of CNC machine tool equipment:
First, the structural characteristics of the foundation components: CNC machine tools are an important foundation, their basic function is to support the bearing and maintain the relative position of the executive organs. CNC machine tools in one, not only to be able to withstand the rough work when the big eat, big cutting force, but also to ensure the precision of the finishing work.
Second, the structural characteristics of the drive module: the main drive module to achieve the cutting power required by various tools and tools, and in a wide range of speed to ensure constant power output, while the CNC machine tool to get the best cutting speed, the main drive must be in a wide range of stepless variable speed. Current CNC machine tools using high-performance DC and AC stepless speed spindle motor, the machine tool’s graded variable speed drive chain is greatly simplified.
Third, the characteristics of the feed module: the module driven by the motor, ball screw and tool or workpiece to complete the movement in all directions.
IV. Structural characteristics of other models
(1) operating table
CNC milling and CNC milling center, the use of internal structure has the characteristics of CNC into the drive mechanism of the rotary, circular arbitrary angle of indexing and feed movement. For multi-process CNC machine tools, the configuration of automatic exchange of operating tables to further shorten the auxiliary time.
(2) tool holder module
Rotary tool holder. Replace the spindle tool change and automatic tool change module with tool magazine and multiple tool holders, multiple spindle layout plays an important role in improving efficiency and automation level. In order to make the tool in the machine tool positioning, clamping up, in some places, there are some standard tool means and machine clamps.
(3) CNC accessories
The role of machine tool accessories is to work with the machine tool to achieve automation. CNC machine tool-specific accessories are: 1 to the tool instrument, 2 automatic chip conveyor, 3 automatic chip conveyor, material storage and loading and unloading devices, 5 automatic cooling and lubrication and a variety of new supporting parts such as guide guards.
(4)Lubrication module
Cutting oil filling method that the needle for different objects taken in different ways to lubricate, in the way of oil injection, a variety of processes are with other work phase. Cutting oil system lubrication is sufficient, the amount of oil supply is easy to control, heat dissipation and the ability to remove impurities, through the oil pump will be cutting oil from the oil tank suction after delivery to the need to cut parts. Oil injection methods are: drip oil way, splash way, spray oil way, etc.
