1. General principles of the knife path:

Rough opening: Under the larger load of the machine tool, the largest possible tool should be selected for most local conditions, the largest possible feed amount, and the fastest possible feed. Under the condition of the same knife, the feed is proportional to the amount of feed. Under normal circumstances, the load of the machine tool is not a performance. The criterion for selecting a tool depends mainly on whether the two-dimensional angle and three-dimensional arc of the product are too small. After the knife is selected, the length of the knife is fixed. The guideline is that the length of the knife is greater than the processing depth. For large workpieces, it is necessary to think about whether the chuck can intervene. Dongguan Kaicheng Precision Hardware Co., Ltd. is based on CNC processing, CNC lathe processing, automatic lathe processing, turning and milling combined processing, and the quality is guaranteed!

Light knife: The purpose of light knife is to meet the processing requirements of the surface brightness of the workpiece and reserve an appropriate margin. In the same way, the light knife should be as large as possible and feed as fast as possible. Since the fine knife requires a long time, use the appropriate feed and feed. Under the same feed, the larger the horizontal feed, the faster, the surface feed is related to the brightness of the processed surface, and the size of the feed is related to the surface shape of the surface. The precision hardware is opened without damaging the surface. Small margin, big knife, fastest speed, proper feed.

2. Fixing method:

1. All clamps are horizontal and vertical.

2. Vise clamping: the clamping height should not be less than 10 mm, and the clamping height and processing height must be specified when processing the workpiece. The processing height should be about 5 mm higher than the vise three-dimensional, the purpose is to ensure the sturdiness, and at the same time not to damage the vise. This kind of clamping is a common clamping, and the clamping height is also related to the size of the workpiece. The larger the workpiece, the higher the clamping height.

3. Clamping of the splint: the splint is coded on the task table, and the workpiece is locked on the splint with screws. This kind of clamping is suitable for workpieces with insufficient clamping height and large processing force, ordinary medium and large workpieces, and the effect is relatively good. .

4. Code iron clamping: When the workpiece is large, the clamping height is not enough, and the wire is not allowed to be locked at the bottom, the code iron is used for clamping. This kind of clamping needs to be clamped twice. The four corners are first coded, the other parts are processed, and then the four sides are coded to process the four corners. During the second clamping, do not let the workpiece loose, yard first and then loosen. You can also code both sides first and process the other two sides.

5. Clamping of the tool: the diameter is above 10mm, and the clamping length is not less than 30mm; the diameter is below 10mm, and the clamping length is not less than 20mm. The clamping of the tool must be strong, and Dongguan Kaicheng Precision Hardware will prevent the knife from colliding and indirectly pulling out the workpiece.
