According to the different feeding methods, CNC double end grinding machines can be divided into different types such as through type, reciprocating type, and vertical grinding When there is a high demand for workpieces and high precision requirements, a through type double end grinder is generally used. The so-called through type grinder (as shown in the figure) is to place the workpiece into a circular loading tray at appropriate intervals, and the loading tray rotates to bring the workpiece into the grinding wheel. The workpiece and loading tray pass through the grinding wheel at a specific speed and time to complete the grinding process, and are then carried out by the rotating loading tray This rotating through type CNC double end grinder can automatically load and unload materials, greatly improving the production efficiency of workpieces and controlling the single piece processing cycle within 5 seconds
CNC grinding machineIt is a precision surface grinder suitable for batch processing, and has functions such as groove cutting and step grinding The front and rear host seats of the device adopt a mature and stable T-shaped splicing structure, with column movement mode and independent relative motion between the workbench and the sliding frame The reciprocating motion of the workbench, the forward and backward motion of the column, and the up and down motion of the grinding head are all directly driven by AC servo motors through ball screw transmission
This machine adopts a CNC system, with three CNC axes controlling the three axes of the machine tool respectively. It can complete automatic cyclic grinding of flat surfaces, grooves, and steps in one installation of the workpiece, and has automatic feed of the grinding wheel, coarse, fine, and spark free grinding functions
1. Front console and rear console
The front and rear host seats adopt a mature and stable T-shaped splicing structure with high overall rigidity and seismic performance, which can meet the requirements of high-precision equipment for basic components
2. Workbench
CNC grinding machineThe workbench adopts double V-shaped sliding guide rails, which have high rigidity and load-bearing capacity, and move smoothly and reliably The static pressure guide rail of the workbench greatly improves the accuracy and service life of grinding, and the AC servo motor directly drives the ball screw to control the movement of the workbench
3. Column and sliding frame
The sliding frame adopts double V-shaped guide rails, and the rear host seat provides full stroke motion support for the sliding frame. The guide rails adopt plastic coated sliding rails, which have good positioning accuracy and wear resistance The motion power adopts AC servo motor to directly drive the ball screw pair to control the forward and backward movement of the sliding frame
4. Grinding head group
The grinding wheel spindle adopts a flange type high-precision dynamic and static bearing support, and is equipped with an independent spindle temperature control oil tank, which ensures that the spindle always maintains high rotational accuracy, rigidity, and working stability during the grinding process It is also possible to customize and install a spindle frequency converter to change the spindle speed and improve grinding efficiency The feed system of the grinding head group adopts a built-in encoder with brake, and the AC servo motor directly drives the ball screw to control the feeding motion of the grinding head group
5. Lubrication and protection
The independent automatic circulation lubrication system provides regular cleaning and lubrication for the guide rail and screw And it has a pressure loss alarm function Equipped with a fully sealed protective cover, it effectively prevents grinding fluid from splashing out of the machine and minimizes the impact of dust and mist on the environment, ensuring a clean environment and the health of operators
