The reaming method is shown in Figure 7-4, and the reaming allowance (D-d) can be consulted in the table. The form of the reamer varies with the diameter. The diameter of Φ10~Φ32 is a taper shank reamer, as shown in Figure 7-5a. The diameter of Φ25~Φ80 is a sleeve type reaming drill, as shown in Figure 7-5b.
Reaming is a finishing method for holes on the basis of semi-finishing (reaming or semi-finishing boring). The size tolerance of the reaming hole can reach IT9~IT6, and the surface roughness value can reach Ra3.2~0.2μm.
Broaching of aluminum alloy, 스테인레스 스틸, copper and titanium alloy parts:
Broaching is a highly efficient finishing method. In addition to broaching round holes, it can also broach through holes and internal keyways of various cross-sectional shapes, 그림과 같이 7-19. The achievable dimensional tolerance grade for broaching round holes is IT9~IT7, and the surface roughness value is Ra1.6~0.4μm.
Mechanical surface treatment of parts
It mainly includes wire brush roller polishing method and shot peening method. The polishing method is that the brush roller is driven by the motor, and the brush roller rotates at a high speed on the upper and lower surfaces of the strip in the direction opposite to the movement of the rolling piece to remove the oxide scale. The brushed iron oxide scale is washed away with a closed circulating cooling water washing system.
CNC machining parts refers to a process method that uses information and digital devices to control the movement of parts and cutters to process parts on a CNC machine. It is an effective way to solve variable rapid prototyping components, small batch parts, complex shaped parts and high precision CNC machining components and achieve high efficiency parts.
Before operators can run CNC programs, they must prepare the CNC machine for operation. These preparations include fixing the workpiece directly on the machine, on the mechanical spindle, in machine vision devices or similar workpiece fixing devices, and connecting the required tools (such as drills and mills) to the appropriate CNC machining components.
Once the machine is fully installed, the operator can run the CNC program.
CNC 가공부품의 표면처리 기술 및 기능, 표면 마무리 비용
각 제품마다, CNC 가공 부품에 대한 특정 표면 처리를 수행할 수 있습니다.. 하지만, 제품의 표면 마감 처리로 인해 해당 비용이 증가하는 경향이 있습니다..
일부 표면 처리, 높은 광택과 같은, 가공 과정의 흔적을 제거하는 것을 목표로 합니다..
예::
표면 마감으로 반사 표면을 생성할 수 있습니다..
무광택 표면 처리 또는 샌드블라스팅으로 반사 제거.

CNC milled parts
How are CNC milled parts manufactured?
CNC milled parts are machined on CNC milling machines with the help of rotating tools. CNC milling machines with different degrees of freedom of movement are used: 3-중심선, 4-axis and 5-axis milling machines.
