CNC Milling Machine Technical Agreement
Product Name: CNC Milling Machine
Model: M7126
1. Overview
The M7126 machining center features X, Y, and Z three-axis control and a servo-driven spindle. Equipped with a 12-tool magazine, it enables multi-process machining (drilling, milling, boring, reaming, tapping, etc.) for complex parts such as discs, plates, housings,cams, and molds in a single setup. The three-axis linear guide structure ensures high precision and is suitable for both single-piece and batch production across industries. Program-controlled machining shortens production cycles, delivering significant economic benefits.

2.6 Pneumatic System
● Filtered air supply (0.5-0.7 MPa) with solenoid valves controlled by PLC for tool clamping, spindle cooling, and blow-off.
2.7 Protection & Lubrication
● Fully enclosed guards for chip/coolant containment.
● Centralized auto-lubrication for guides and screws.
2.8 Working Conditions
● Power: 380V±10%, 50Hz±1%
● Temperature: 5-40°C (optimal: 15-25°C)
● Humidity: 40-75%
● Air pressure: 0.5-0.7 MPa
2.9 CNC System

Applications
Why Choose a Vertical Mill Over Horizontal?
Vertical mills offer lower costs, better visibility for complex jobs, and easier setup—perfect for businesses prioritizing flexibility and affordability. Horizontal mills excel at mass production but come with higher investments .
EV Battery Plates: Drilling 1,200+ cooling holes in copper composite trays.
Hydraulic Valve Blocks: Deep-cavity milling ductile iron manifolds (Ra 1.6μm).
Consumer Electronics: CNC engraving aluminum alloy laptop chassis.
Defense Triggers: Hard-milling 4340 steel components at 52 HRC.
