The CNC cutter is suitable for mass production of copper, iron, aluminum, stainless steel bar material within 35mm, and automatic mass production of forging and punching pieces with the opening mode within 50mm, and can also install hydraulic chuck to achieve single production of parts within 250mm. Adopt high rigidity whole castings full protection base, dense organization, good strength, appropriate hardness, low friction coefficient. It is suitable for processing products with unilateral cutting amount within 2mm, precision tolerance within ±0.01mm and finish degree within 1.6. The bed is 35 degrees inclined, the overall box structure greatly enhances the overall rigidity and stability of the machine tool, and has the function of shock absorption, reduces the tool loss, improves the quality of the workpiece, and provides users with high efficiency and high reliability in use. The main shaft adopts a total of 5 P4 precision bearings in the first three and the second two, and the labyrinth waterproof design and the cooling vane type headstock design achieve the best waterproof and dust proof effect.

When machining parts on CNC row machine, there are generally two conditions. The first condition: there are parts drawings and blanks, to select the suitable CNC lathe for processing the parts. The second situation: there is already a row of CNC lathe, to select the parts suitable for processing on the machine tool. No matter what kind of situation, the main factors to consider are the data and class of blank, the degree of clutter of the outline shape of the part, the size and size, the processing accuracy, the number of parts, the heat treatment requirements.

CNC lathe cutting is to have a specific program, program preparation personnel should be based on the machine tool manual, programming manual, cutting table, standard things, fixture manual and other information to analyze the process. Here we introduce this aspect of programming common sense.

In general, when the program is prepared, the appropriate machine tool should be selected according to the data of the workpiece to be processed, the contour shape, the processing accuracy, etc., the processing plan should be drawn up, the processing order of the parts should be determined, and the tools, fixtures and cutting parameters used in each process should be determined. In addition, programmers should continue to summarize and accumulate practical experience in process analysis to write high-quality CNC machining programs.

The choice of clamping force direction and application point of NC tool set machine

The clamping force should face the main positioning reference. Since the drill has vertical requirements for the /4 surface workpiece, surface A is used as the main positioning base surface during processing, and the clamping force is F, and the direction should be toward the /4 surface. If the clamping force is changed to B-side, the positioning position of the workpiece is damaged due to the Angle error between the side /4 of the workpiece and the B-side of the bottom surface of the industrial control machine, which affects the perpendicality requirement of the hole /4 surface.

The point of application of the clamping force should be located within the support range of the positioning element and close to the geometric center of the supporting element. The clamping force acts outside the supporting surface, causing the workpiece to tilt, move, and destroy the positioning.

The direction of the clamping force should be conducive to reducing the size of the clamping force. When drilling, the clamping force is J and the axial cutting force is F. The gravity C of the workpiece is the same direction, and the clamping force required for processing is small.
