Vaste ondersteuningsmallen en -bevestigingen CNC-frezen

2. Speciale verwerking

-- Snijden/Indexeren: Zaagbladen frezen gesneden werkstukken, verdeelkoppen zorgen voor gelijkmatig verdeelde gaten/tanden.

-- Speciaal gevormde sleuven: Zwaluwstaartfrezen en T-sleuffrezen verwerken specifieke verbindingsstructuren. Typische toepassingsscenario's

-- Automobielindustrie: frezen van vlakke oppervlakken van motorblokken, bewerken van versnellingsbakken.

-- Lucht- en ruimtevaart: Frames van rompen, structurele componenten van landingsgestellen.

-- Elektronica: Montagesleuven voor printplaten, reeksen koelribben.

Vergelijking met andere

ProcessenDraaien:

Geschikt voor roterende onderdelen (bijv. assen), frezen is beter voor polyhedrale/complexe profielen.

Boren:

Frezen kan een aantal boorbewerkingen vervangen (bijvoorbeeld gaten met een grote diameter), maar met een hogere precisie.

-Multi-Station Machining: Use OK fixtures for rapid positioning of batch parts.

-Precision Machining: Zero-point positioning systems ensure repeatability of ±0.003mm.

3. Technical Parameters and Selection

—Clamping Force: Pneumatic clamps typically provide a clamping force of 500-2000N

—Precision Requirements: High-precision clamps must maintain a positioning accuracy of ±0.01mm.

Tolerances for CNC Milling

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.
