What are the features of cnc prototype model processing

is the process feature of the CNC machining center first, and it is characterized: complete milling, drilling, boring, hinge, tapping and other multi-process processing as much as possible in the case of one clamping; Large cutting amount is used.

cnc prototype processing materials: ABS: transparent ultra-high temperature resistance, black, imported, domestic and so on. POM (Saigang)(Acrylic force)MC (Nylon) PC, PP, PA, BT, PVC, etc. Aluminum Alloy, copper and so on.

after the workpiece is clamped once, the digital control system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the spindle speed of the machine tool, the feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions, and complete the processing of multiple processes on several surfaces of the workpiece in turn. The whole processing process is automatically controlled by the program, not affected by human factors of the operator.

molding features: large molding size, high strength, good toughness, fast speed, at the same time, the cost is relatively low

Generally, the upper and lower sides of the workpiece are processed, under special circumstances, the workpiece will be processed on three sides, four sides, five sides or six sides. In the process of processing, we will (Workpiece) Keep the glue on the side basket and use the side basket to pull the bone to the product (Workpiece)Fixed, pouring gypsum to products (Workpiece)Positioning, processing products (Workpiece) And CNC worktop will not have a bonding effect, better guarantee the processed products (Workpiece)No deformation and product (Workpiece)The material level is accurate.

Secondly, it is a problem that should be paid attention to when determining the process plan:

(1) Determine the processing content of the CNC machining center, determine the installation base surface, processing base surface, machining allowance, etc. of the workpiece, and arrange the processing process for the purpose of giving full play to the efficiency of the CNC machining center.

(2) For complex parts, due to thermal deformation during processing, internal stress will occur after quenching, and deformation will also occur after the parts are stuck, therefore, it is difficult to complete the whole process after one clip, and two or more clips can be considered at this time.

(3) When arranging the processing process, we should follow the principle of gradual refinement. First arrange heavy cutting and rough machining, remove the machining allowance on the blank, and then arrange the content

(4) Using a large flow cooling method, in order to reduce the impact of a large amount of heat generated during processing on the machining accuracy, in order to improve the durability of the tool, it is necessary to actively adopt the cooling method of large flow
