Core Characteristics of Milling Processing
1. Multi-Edge Cutting and Efficiency
-- Milling cutters have multiple cutting edges (e.g., end mills with 4-6 edges), which can participate in cutting simultaneously, sharing the load and improving efficiency (30%-50% higher than single-edge tools).
-- Suitable for large feed rates or high cutting speed machining, such as surface milling with a cutting depth of up to 5-10mm.
2. Intermittent Cutting and Impact Vibration
-- The cutter teeth engage and disengage from the workpiece periodically, causing fluctuations in cutting force, requiring machines with good rigidity (e.g., heavy-duty milling machines) to ensure precision.
-- Intermittent cutting facilitates tool cooling and extends tool life, but durable tool materials (e.g., carbide) must be used.
3. Process Flexibility-- By changing tools (e.g., face mills, T-slot mills), it can process complex features such as flat surfaces, grooves, gears, and curved surfaces.
-- Supports multi-axis linkage (e.g., five-axis milling) to achieve machining of three-dimensional complex profiles (e.g., mold cavities).4. Controllable Surface Quality-- Adjusting cutting parameters (e.g., feed rate, speed) can control surface roughness (Ra 0.8-12.5μm).
-- End mills' secondary cutting edges can polish surfaces with roughness down to Ra 0.4μm.Range of Milling Processing
1. Basic Processing-- Flat/Step Surfaces: Face mills (end mills) process large flat surfaces, three-edge mills process steps.
-- Grooves/Keys: End mills mill straight grooves, keyway cutters process key slots (accuracy IT8-IT9).2. Complex Feature Processing
-- Gears/Threads: Modular shaped end mills process gears, thread mills process threads.
-- Cavities/Molds: Ball end mills process three-dimensional curves (e.g., injection molds).
2. Special Processing
-- Cutting/Indexing: Saw blades mill cut workpieces, dividing heads achieve evenly spaced holes/teeth.
-- Special-Shaped Slots: Dove-tail milling cutters and T-slot mills process specific connection structures.Typical Application Scenarios
-- Automotive Manufacturing: Milling flat surfaces of engine blocks, processing gear case shells.
-- Aerospace: Frameworks of fuselages, structural components of landing gear.
-- Electronics: Mounting slots for circuit boards, arrays of heat sink fins.
Comparison with Other
ProcessesTurning:
Suitable for rotating parts (e.g., shafts), milling is better for polyhedral/complex profiles.
Drilling:
Milling can replace some drilling operations (e.g., large diameter holes) but with higher precision.
Parts requiring the highest complexity are made using 5-axis CNC milling which allows machining from multiple angles in a single setup. It improves precision, dimensional accuracy, and production time.

MoreCNC Milling is a method of using a rotating multi-edged tool (milling cutter) on a milling machine to process the workpiece. The main cutting motion is the rotation of the tool. According to whether the main movement speed direction during milling is the same as or opposite to the workpiece feed direction, it is divided into down milling and uphill milling. Scope of application: Plane milling, step milling, groove milling, forming surface milling, spiral groove milling, gear milling, and cutting.
MoreHigh flexibility in CNC machining. It can adjust the processing program according to the characteristics of the parts, and can also be adapted to various materials. Mechanical processing can operate when the material is relatively hard, brittle, thick-walled, etc., and can process multiple processes at the same time, with high flexibility.
MoreIn addition to the characteristics of ordinary milling machines, CNC milling is also highly adaptable and flexible for parts processing. It can process parts with particularly complex contour shapes or difficult-to-control dimensions, such as mold parts, shell parts, etc.
