Machining center is a CNC maλ∏₽chine with many functε↓₹♦ions

CNC machine tools include many¶φα→ types, such as machining ceΩ nters, CNC lathes, CNC drilling machi®☆✘nes, CNC milling macε>←→hines, etc. These can be cφ₽®alled CNC machine tools, and the✔σ ± machining center to be said tod¥₩ay is also a type of CNC maα> chine tools.

CNC gantry machining center is a nuβφ♥merically controlled→≈ ' machine tool with many functions. It  £€±integrates milling, drilling, tw↓ >♥isting, boring, rose thread,φ∑≠↓ and thread milling into&₩ one. It has a variety of✔®∏ technological methods✘​$ and strong compreheβ∑§nsive processing cap ®abilities. Compared w™γ∏ith ordinary machine tool™≠₩♣s, CNC gantry machining c'≤enters have many significant≈ Ω≠ technological features.

The machining center can reduce theγ♥"  number of clamping times×∏♦ of the workpiece, eliminate positioninφ§λ‍g errors caused by multiple clamping♦™≈‌, and improve machin‌ §÷ing accuracy. When the positio₹↑βλn accuracy of each mach→ ining part of the part is high, CNC gantry machining center manufactu♠₹rers can use machining cent↔‍er processing to process each part in₩§ one clamping, avoiding posit​↔ioning errors caused by multiple ε>clamping of the workpi☆γ→€ece, which is beneficial♥ε To ensure the position accuracy "§'requirements of each processinδ↑¶≥g part.

At the same time, machining cen÷ ters mostly use semi-c≥≤$losed or even full-closed pos←β®ition compensation f↓✔★unctions. They have higher posit®∞ioning accuracy and repeated positio¥§ning accuracy. Dimensional errors ♣≠→≤generated during processi←‍₩ng can be compensated i≥×÷•n time. Compared with ₽♥≥ordinary machine tools, Hε igh dimensional accuracy. In addition,≠ε↓ the use of machining €πε£centers can also red©÷δ₽uce the auxiliary time for ↕•loading and unloading↓£↕↑ workpieces, save a lot of special and ÷ general process equipment, and reduc₹←α✔e production costs.

Because of the rigidity and high₹₩ power of the machining center, it©•‍¥ is necessary to choose as much cutting®☆ amount as possible in the machining"σ process, which can save machining₩♣≈✘ man-hours. However, th$≈‍e temperature rise generated δ✔∑under this condition will affect t$εhe machining accuracy of th∞ e part, so it is necessary t♣♣o select the appropri>↓$ate tool and fixture, and pay atten>×↔δtion to sufficient cooling.

The processing sequence ₹←should be based on the principle of rΩ ¥∞oughing and finishing, tδ‍×∞hat is, heavy cutting and∞  roughing are performed first, but mos≥λt of the machining allowance ¶αδon the part blank is removed, and th>​en the processing steps with small h​λ♠eat generation and low pr±δ→ocessing requirements are arra ✘nged to make the par×γ ts Allow sufficient ti∑>∑me for cooling before machining​↑, and then finish mach≈₽¶ining. Each process should minδ•ε¥imize the amount of idle stroke movemeπ¶∑&nt and reduce the number of tδ§ool changes. The recommende©✔d processing sequence is: milling larg ≠α e planes / (separation of rough and♥‍ fine) / rough boring, blu®¶e fine boring, end mill processin‍¶↕₩g, dozens of centers, drilβ₽ling, drilling, rose thread, ™☆≈and hole finishing, (Winning,™₽≥  boring, fine milling, etc.).
