When the machining manufacturer carries out the machining of mechanical parts, the workpiece should be roughing in layers with different lengths of knives when it is too high, and after using a large knife for roughing, the residual material should be removed with a small knife again. Use a flat bottom knife to process the plane, and use the ball knife sparingly in order to cut down the processing time; if there is a skew and it is an integer, use the skew knife to process it. The following is a brief introduction to the things you need to pay attention to when machining parts for machining manufacturers.

      When the machining manufacturer carries out the machining of mechanical parts, the workpiece should be roughing in layers with different lengths of knives when it is too high, and after using a large knife for roughing, the residual material should be removed with a small knife again. Use a flat bottom knife to process the plane, and use the ball knife sparingly in order to cut down the processing time; if there is a skew and it is an integer, use the skew knife to process it. The following is a brief introduction to the things you need to pay attention to when machining parts for machining manufacturers.

      Reasonable set tolerance, make the processing accuracy and computer calculation time between the mutual balance, more processes, reduce the empty knife time; blank material hardness is high, choose reverse milling; blank material hardness is low, choose smooth milling. Roughing reverse milling, finishing smooth milling; tool material toughness, low hardness to adapt to roughing, tool material toughness, high hardness to adapt to finishing.

      Machining manufacturers CNC machine tool processing on the machined parts of the clamping method should also be a reasonable choice of positioning datum and clamping program, in the selection of fine datum, generally follow the “datum uniformity” and “datum overlap” these two principles, in addition to these two principles, and also consider trying to complete the machining of all surfaces in the positioning and clamping. Consider also try to complete the processing of all surfaces in the positioning and clamping, therefore, to choose a convenient way to facilitate the positioning of all surfaces can be processed.

      Workpiece clamping should be able to complete the processing of all surfaces of the workpiece; to determine the placement of the workpiece on the worktable, should be considered to take into account the processing of the various stations, the length of the tool and the rigidity of the tool on the quality of processing. In the control of the fixture used in the processing, should be as far as possible to choose from the general components assembled, and can be adjusted fixture, shorten the production preparation cycle.

      Machining plant arrangements for machining sequence, the basic principles must be observed, including “first face after the hole”, “first rough after fine” and so on. According to the tool centralized process processing, to avoid repeated use of the same tool many times, reduce the number of times and time to change the tool.

      Hole systems with high coaxiality requirements should be positioned so that all machining of the hole system is completed before machining the hole system at other coordinate positions, which eliminates errors generated during repetitive positioning and improves the coaxiality of the hole system. Choose to determine the good knife point and tool change point, once determined, should not be replaced.

      About machining manufacturers for parts processing need to pay attention to things, the above has been explained very clearly, I hope to help you.
