Medical light-curing equipment for dental metal custom accessory processing

Detailed technical specifications for the processing of metal components in dental equipment:

1. Core Material Properties and Selection：

-- Titanium Alloy (Ti-6Al-4V): Excellent biocompatibility (compliant with ISO 10993-5 standards) and mechanical properties, with a density only 40% of iron, tensile strength ≥ 900MPa, suitable for long-term implant components like implants and abutments.

-- Cobalt-Chromium Alloy: Hardness reaching HV 400-500, manufactured using vacuum casting and CNC finishing processes for denture frameworks, with superior deformation resistance compared to traditional nickel-chromium alloys.

-- Precious Metal Alloy: Gold content ≥ 75% in Au-Pt-Pd alloy used for high-precision crowns, offering excellent ductility but at a higher cost.

2. Key Processing Technologies：

-- Precision CNC Machining: Five-axis machining centers achieving ±0.02mm accuracy, used for thread processing of titanium alloy implants (tolerance ±0.01mm).

-- 3D Printing Technology: SLM process for producing porous titanium alloy structures (porosity 60-80%), suitable for personalized implants, with a layer thickness of 20-30μm.

-- Surface Treatment: Titanium alloy treated with sandblasting and acid etching (SLA process), with a roughness for bone integration surface of Ra 0.8-1.6μm.

3. Typical Application Cases：

-- Digital Implants: Manufactured using SLM technology, with an internally porous structure that improves bone integration rate, clinical success rate of 98.7%.

-- Cobalt-Chromium Frameworks: Achieved a bite surface precision of IT6 grade after CNC finishing, extending service life by 30%.

-- Orthodontic Brackets: 3D printed titanium alloy brackets, enabling personalized design, shortening treatment duration by 20%.

4. Industry Development Trends：

-- Additive Manufacturing: The application of 3D printing in craniofacial reconstruction and complex structures like implants continues to grow.

-- AI-Assisted Design: Combining artificial intelligence to optimize the mechanical properties and biocompatibility of dental metal components.

-- Material Innovation: New titanium-based biomaterials enhance performance through additive manufacturing processes to meet high-demand clinical scenarios.

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.
