Na povrchu časti sú vrcholy a údolia s malými rozostupmi, a mikro-geometrické charakteristiky ním tvorené sa nazývajú drsnosť povrchu. Pri CNC obrábaní dielov, vzniká v dôsledku stôp po nástroji, ktoré nástroj zanecháva na povrchu dielu a plastickej deformácie povrchového kovu pri CNC rezaní a štiepaní.
Calibrating tools for CNC machine tools is an important skill in machining. The accuracy of the tool setting determines the machining accuracy of the part, and the efficiency of the calibration tool directly affects the machining efficiency of the part. Tool setting is very important to machine tool processing operations.
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.
Single-edge boring tool boring has the following characteristics:
(1) The adaptability of boring is strong. Boring can be carried out on the basis of drilling, casting and forging holes. A wide range of achievable dimensional tolerance levels and surface roughness values;
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.
S cieľom splniť rôzne potreby zákazníkov v oblasti obrábania, Methods Machine Tool Company ponúka dva modely strojov Nakamura Tome vybavené osou B. Obrábací stroj STW-40 so štandardným 40-polohovým automatickým výmenníkom nástrojov je určený na spracovanie veľkých a ťažkých dielov. Ako napr: odliatky a výkovky, a dokáže spracovať obrobky až 17 palcov v priemere. Avšak, v reakcii na potreby zákazníkov, Methods Machine Tool Company môže teraz poskytnúť menší model obrábacích strojov s osou B, a to NTJ (Vežička osi B).
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 (kov, plast).
Po prvé, 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.
