Come in and take you easily to understand the ordinary CNC gantry milling machine

The development of ordinary CNC gantry milling machines and new planning concepts lead the trend of modern machining. The ram-type without boring shaft and the structure of interchangeable milling heads based on the concept of high-speed machining show the style, which can replace traditional milling. Processing trends. Various milling head accessories represented by two-coordinate pendulum angle milling heads have become the primary method to complete high-speed and high-efficiency composite machining, with wider technological functions, greater power and stronger rigidity.

The structure and function characteristics of the ordinary CNC gantry milling machine:

1. The main milling head adopts the ram-reduction gear box separation design to improve the accuracy of the milling head. Two gears are used in the gear box to achieve low-speed, high-torque and high-speed constant power, which can satisfy rough machining and precision. Process requirements for processing.

2. The high-precision spindle combined bearing ensures the high-function and high-precision of the main milling head. The ram milling head of the ordinary CNC gantry milling machine also selects hydraulic oil cylinders for balance and smooth movement.

3. All three-axis transmission adopts imported high-precision preloaded ball screw or double pinion-rack without gap transmission, and then the transmission accuracy is ensured.

4. The three-axis response uses a photoelectric encoder to complete the semi-closed-loop azimuth response, or according to user needs, selects a grating ruler to complete the full-closed-loop azimuth response.

Ordinary CNC gantry milling machines meet the critical processing needs of oversized parts in key areas such as aerospace, power generation equipment, and cars; high-speed precision CNC lathes, machining centers and other products are widely used in aerospace, electronics and other work areas, and drive Many small and medium-sized companies have upgraded their equipment and upgraded their industries.

When connecting the power supply of ordinary CNC gantry milling machine, the voltage must be stabilized, and the voltage fluctuation must be within the specified range. If it exceeds this range, it will cause damage to the machine tool motor. The temperature of the installation environment must be less than 30°C, and the humidity must be less than 30°C. Less than 80%, if these two conditions are not met, it will affect the service life of the machine tool control system. In addition to the high requirements for the installation environment, we should also pay attention to:

1. A certain range of working space should be reserved around the ordinary CNC gantry milling machine, and no objects are allowed to be stacked to avoid obstacles.

2. The operator must wear protective clothing before working. It is not allowed to wear gloves when operating a normal CNC gantry milling machine.

3. After checking and adjusting the processing parameters, the origin and the motion track, the parts can be processed.

4. Check carefully whether the workpiece clamping of the ordinary CNC gantry milling machine is installed and tightened, and whether all the motion bearings have returned to the zero point of the machine tool.
