1.Here Are Four Reasons To Choose Us
1.1 Not the cheapest, but fairly priced
We don’t compete on the lowest price. Instead, we streamline costs through automated scheduling, bulk material procurement, and process optimization. Same precision, better price. Same budget, more reliable quality.
1.2 Real production capacity, not empty promises
Factory video: 50+ CNC machines, 50+ team members, 24/7 production.
Even if you send your drawings and requirements on Friday afternoon, you’ll receive an accurate quote by Monday—because we have real machines, a real team, and a real production schedule.
1.3 Tolerances aren’t just a slogan; they’re our daily standard
Medical-grade implants? Aerospace sensor housings? We use CMM equipment to inspect critical dimensions and issue inspection reports. We don’t settle for “close enough”; we strictly meet tolerance requirements.
1.4 Extensive Material Capabilities
Aluminum (6061/7075): The lightweight choice with top-notch anodizing results.
Stainless Steel (303/304/316): Corrosion-resistant with proven medical-grade surface treatments.
Titanium Alloy (Gr2/Gr5): Hard to machine? We’ve got specialized tools and cooling solutions.
Brass/Copper: Ideal for electrical/thermal components, easily achieving a Ra 0.4 surface finish.
Engineering Plastics (PEEK, PTFE): Non-metals machined to metal-grade precision.
2. Default Tolerances and Specified Tolerances
Our default tolerances comply with ISO 9001. To ensure we produce products that best meet your requirements, we recommend specifying tolerances on your drawings.
For example:
• Linear dimensions: ±0.03 mm
• Outer diameter/bore: ±0.03 mm
Our maximum machining range: 800 × 500 × 500 mm (suitable for most shaft and disc components).
For higher precision requirements (e.g., ±0.005 mm), please specify this on the drawing. We will utilize dedicated high-precision equipment for specialized machining.
3. Engineers Consistently Choose Us
We specialize in the precision machining of rotating components: shafts, sleeves, couplings, flanges, threaded parts… Any component that is circular, rotates, or requires precise assembly—we have the expertise to deliver it quickly and flawlessly.
Whether you’re a startup or a medical device company in Europe or elsewhere, SzCrealink provides reliable back-end manufacturing support for highly consistent, repeatable metal components.
Our daily turning operations:
Turning external cylindrical surfaces and internal bores
Taper turning (precise angle/diameter control)
Thread turning (metric, inch, NPT—male and female threads)
Precision face turning (ensuring perpendicularity and flatness)
Deep-hole boring and reaming (with internal coolant tool holders)
Cutting ring grooves, relief grooves, and sealing grooves
Automatic cutting and blanking (high efficiency for mass production)
4. Preliminary Considerations for Material Selection
Aluminum Alloy: High cutting speed, lightweight, but prone to tool adhesion—we use coated tools and high-pressure coolant to achieve a smooth, burr-free surface.
Stainless Steel: Hard, tough, and prone to work hardening—requires sharp carbide tools, slow feed rates, and aggressive cooling.
Titanium Alloys: High strength but heat-sensitive—low-speed cutting + heavy coolant to prevent discoloration or cracking.
Brass: Soft and ductile, with natural self-lubricating properties, capable of producing mirror-like surfaces, making it ideal for small precision components.
Red Brass: Excellent thermal conductivity makes temperature control challenging—we reduce spindle speed and use sharp PCD tools to prevent tool clogging.
5. In Addition To Machining, We Offer One-Stop Surface Finishing Services.
Machining parts is just the first step—surface finishing is where we truly shine:
Anodizing (aluminum): Wear-resistant + insulating + customizable colors (black, red, blue, gold, etc.)
Passivation (Stainless Steel): Removes free iron ions, significantly improving rust resistance
Glass Bead Blasting: Creates a uniform matte texture, hides machining marks, and enhances the feel
Powder Coating: Controllable thickness, unlimited color options—ideal for outdoor components
Mechanical Polishing: Ra ≤ 0.2, mirror-finish polishing for decorative or optical applications
6. Design Tips: Draw This Way for Faster, More Cost-Effective, and Higher Yield!
Our process engineers have summarized the most production-friendly design boundaries (in mm):
| Feature | Recommended Value | Limit Value (May incur additional charges or extended lead time) |
| Minimum Outer Diameter | ≥2.0 | Achievable down to 0.4 (requires special tooling) |
| Internal Radius | R7 | Minimum R0.3 (sharp corners prone to chipping) |
| Metal Wall Thickness | ≥0.7 | 0.4 is critical threshold (prone to deformation) |
| Plastic Wall Thickness | ≥1.4 | Below 0.9 prone to shrinkage and cracking |
| Deep Holes | ≤12×D | Standard tools only support ≤5×D |
| Threads | Starting from M5, length ≤4×D | M2 possible, but low strength and extended cycle time |
✨ Tip: Unless absolutely necessary, avoid extreme values whenever possible – this will help your parts succeed on the first try and save you unnecessary detours.
7. Leave Cnc Turning To Us So You Can Focus On Your Core Business
In CNC turning, the workpiece rotates while the tool remains stationary (or moves minimally). Compared to milling (“the tool rotates while the workpiece remains stationary”), turning is inherently suited for symmetrical rotating parts.
SzCrealink’s equipment includes:
2-axis lathes: Basic shafts, sleeves
3-axis power turret lathes: Capable of simultaneously milling flat surfaces and drilling eccentric holes
Multi-axis turning/milling centers: Complex parts finished in a single setup, eliminating repositioning errors
We have supplied qualified parts to the following industries:
Aerospace: Fuel connectors, gyroscope housings (titanium alloy + strict traceability)
New Energy Vehicles: Motor shafts, battery terminals (high-conductivity brass)
Medical Devices: Orthopedic instrument handles, endoscope components (PEEK + biocompatibility certification)
Consumer Electronics: Heat sinks, camera mounts (Aluminum alloy + black hard anodizing)
Collaboration is quick and easy:
Just a few steps from concept to finished product.
