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, ステンレス鋼, 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, 図に示すように 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.
What is the cost of CNC machining? man-hour Quote for CNC machining of different materials (金属, プラスチック).
初めに, CNC machining costs will vary significantly due to the different CNC machining parts you are doing. Before placing an order, it is necessary to check the overall budget of your project. You must consider several aspects that affect the cost of CNC machining.
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.
オペレーターが CNC プログラムを実行する前に, CNC マシンを稼働できるように準備する必要があります. これらの準備には、ワークを機械に直接固定することが含まれます, メカニカルスピンドル上で, マシンビジョン装置または同様のワーク固定装置内, 必要なツールを接続します (ドリルやミルなど) 適切な CNC 加工コンポーネントに.
マシンが完全にインストールされたら, オペレーターはCNCプログラムを実行できます.
Surface treatment technology and function of CNC machined parts, Surface finish cost
For each product, a specific surface treatment for CNC machining components can be carried out. しかし, the surface finishes of the product tend to increase the corresponding cost.
Some surface treatments, such as high polish, aim to remove any trace of the machining process.
E.g:
The surface finish can produce a reflective surface.
Matte surface treatment or sandblasting eliminates reflections.

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-軸, 4-axis and 5-axis milling machines.
適合するフライス加工: フライス加工はカウンターローです, またはダウンカレントミリング.
フライス加工の位置: フライス加工はエッジに沿って行われます, または通常のフライス加工.
In the milling in accordance, the tool xira in the same feeling in the progress of the piece. This type of milling is also known as contra-low milling because, when the xiru of the mill is horizontal, the vertical component of the cutting force is directed against the pack. In the milling oposition, also known as milling is against the edge, the opposite occurs, this is, the tool will go in the opposite direction to the best of the piece and the vertical component of the cutting force is directed against the edge.
