Processing equipment for medical testing instrument accessories and customized metal parts processing.

Technical Processing Description of Medical Detector Metal Parts:

1. Core Materials and Processing Characteristics

--Titanium Alloy (Ti-6Al-4V): Suitable for high-precision detector structural components, with excellent biocompatibility (compliant with ISO 10993-5) and mechanical properties, and a tensile strength of ≥900 MPa.

--Stainless Steel (304/316L): Used for detector housings and load-bearing components, requiring precision sheet metal processing (tolerance ±0.05mm) and mirror polishing (Ra ≤ 0.2μm).

--Cobalt-Chromium Alloy: Used for precision transmission components in detectors, with a hardness of HV 400-500 and requiring vacuum casting and CNC finishing.

2. Key Processing Technologies

--CNC Precision Machining: A five-axis machining center achieves ±0.02mm accuracy, used for machining core detector components (such as sensor brackets).

--3D Printing: SLM technology is used to manufacture complex structural parts (such as porous detector brackets), with a layer thickness of 20-30μm and a porosity of 60-80%.

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

3. Typical Application Cases

--Detector Housing: 304 stainless steel sheet metal, galvanized, with an IP65 protection rating.

--Sensor Bracket: CNC-machined from titanium alloy, with a fit accuracy of ≤5μm, ensuring stable test data.

--Test Block: SUS stainless steel standard block (1.0-5.0mm), used for metal detector calibration.

4. Quality Control Standards

--Dimensional Inspection: Coordinate Measuring Machine (CMM) verifies critical dimensions, such as thread depth tolerance of ±0.01mm.

--Biocompatibility: Tested for cytotoxicity (ISO 10993-5) and sensitization (ISO 10993-10).

--Certification Requirements: The production environment must comply with ISO 13485:2016 Medical Device Quality Management System.

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.
