Operation Specifications for Juxin CNC Face Milling and Center Hole Drilling Machine

The operating specifications for the Juxin CNC milling end face center hole machine are as follows: 1. Preparation before operation: The operator must be familiar with the machine's performance, structure, transmission principles, and control programs. They can only operate the machine after receiving on-the-job training and obtaining an operating certificate. Before starting, check the operation records and inspect the following items. Only after confirming everything is correct can the power be turned on. 2. Clamping the workpiece: The workpiece is clamped on the workbench. During the cutting feed process, the end face milling cutter can ensure its fixed length at both ends of the workpiece. For axis-type parts like crankshafts, the center hole of the lathe is usually used for positioning. For the center hole on the sliding frame surface, since there is only one processing tool, it must be turned during processing, and two fixtures are used to complete the machining of the center holes at both ends of the shaft. 3. Adjustment and tool alignment: Adjust the position of the milling power heads on both sides to ensure that the tip distance of the end face milling cutters on both sides is equal to the fixed length of the workpiece. The milling cutter is aligned using two right-angle alignment blocks. 4. Processing process: Using a horizontal CNC servo drive method, both end power heads simultaneously complete the milling of the end faces, while the other two ends simultaneously complete the drilling of the center holes or the outer circle of the sleeve at both ends. During processing, first position the rough blank on the outer circle of the two main spindles to mill the end face, then process the center hole. After that, use the center holes at both ends for rough and fine machining of each axis's surface, threads, keyways, and milled curved end faces, and finally perform rough and fine grinding on each shaft neck. 5. Daily maintenance and care: Establish and strictly implement daily maintenance regulations for the CNC system. Depending on different maintenance needs, regularly check and replace worn parts, and keep the machine clean and well-lubricated. 6. Safety precautions: During operation, strictly follow the operating procedures to avoid overload operation and misoperation. Ensure that all protective devices are intact and effective to prevent accidents. By following the above steps and precautions, the safe and efficient operation of the Juxin CNC milling end face center hole machine can be ensured.

What to Do When the Flat - End Drilling Center Hole Machine Drills at an Angle?

When the flat-end drilling machine appears to be misaligned while drilling, the following methods can be employed to address the issue: 1. Adjust the positioning of the drill bit and workpiece: Ensure that the cutting edge of the drill bit is symmetrical and that the end face of the workpiece is perpendicular to the centerline of the drill bit. If the drilling position is found to be offset or skewed, it can be resolved by sharpening the cross edge, replacing the drill bit, or reducing the feed rate. 2. Use guiding devices: In deep hole machining, using a longer guiding sleeve or guiding block can improve guiding accuracy and reduce misalignment caused by poor guidance. 3. Change the motion form: During deep hole machining, employing a dual rotation method where the workpiece rotates and the tool rotates in the opposite direction along with the feed motion, or having the workpiece rotate while the tool feeds in one direction, can effectively control the degree of misalignment of the workpiece. 4. Regular measurement and correction: During the drilling process, the inclination of the hole should be measured regularly. If it exceeds the standard, timely measures should be taken to correct the misalignment. For example, adjusting the upper carriage rotation, mast hydraulic cylinder, etc., can correct the misalignment. 5. Use stabilizers and spiral drill rods: Using stabilizers and spiral drill rods during the drilling process can increase the length of large-diameter drilling tools, overcoming the bending caused by the gap between the bottom drill rod and the hole wall, thereby reducing drilling misalignment. 6. Appropriately increase cutting speed: Utilizing the centrifugal force of the chips to promote chip removal. If the misalignment is minor, the workpiece or drill spindle can be slightly adjusted for correction; if the misalignment is significant, a sample punch can be used to create a larger indentation or a chisel can be used to carve several grooves in the areas that need more drilling to reduce cutting resistance in that area, allowing the drill bit to shift to the correct position before continuing to drill. By employing the above methods, the misalignment issue during drilling with a flat-end drilling machine can be effectively resolved.

Differences between Double - Spindle Vertical Lathe and Double - Head Lathe

The dual-spindle vertical lathe and the dual-head lathe are two different types of machine tools, which have significant differences in structure, function, and application fields. Dual-spindle vertical lathe: Definition and structure: A dual-spindle vertical lathe is a large mechanical device typically used for processing large and heavy workpieces with a large radial dimension and a relatively small axial dimension, and complex shapes. This machine tool has two independent spindles that can perform processing operations simultaneously or separately. Function: The dual-spindle vertical lathe is suitable for machining various parts such as discs, wheels, and rough bars, including cutting operations for inner and outer cylindrical surfaces, conical surfaces, arc surfaces, end faces, grooves, chamfers, threads, and drilling and boring holes. Application scenarios: Mainly used for processing automotive parts such as gear components, motor shafts, and motor casing discs in the small motor industry. Dual-head lathe: Definition and structure: A dual-head lathe is a lathe with two tool holders, each equipped with tools, allowing for simultaneous processing of two different parts of a workpiece. Function: The dual-head lathe is mainly used in mass production, capable of improving production efficiency and reducing tool change time, suitable for situations where both ends of a workpiece need to be processed simultaneously. Application scenarios: Widely used in mechanical manufacturing, mold manufacturing, and other fields, especially in situations requiring quick workpiece changes or simultaneous processing of multiple similar parts. In summary, the main differences between the dual-spindle vertical lathe and the dual-head lathe are: Structure: The dual-spindle vertical lathe has two independent spindles, while the dual-head lathe has two tool holders. Function: The dual-spindle vertical lathe is mainly used for complex processing of large and heavy workpieces, while the dual-head lathe focuses on improving efficiency in mass production. Application scenarios: The dual-spindle vertical lathe is suitable for precision machining of large parts, while the dual-head lathe is suitable for efficient processing in mass production.
