CNC machining services
We provide supporting processing services such as turning, milling, drilling, tapping, and surface treatment pre-processing for stainless steel castings, mechanical parts, and non-standard metal parts.
Haijin Stainless Steel has long served the fields of stainless steel precision casting, architectural hardware, mechanical parts, and custom metal components. For castings requiring post-processing or parts made according to drawings, we can complete dimensional control, hole machining, thread machining, mating surface machining, and batch delivery according to the drawing requirements.
The casting and machining processes work together, allowing for more direct communication.
We are more familiar with the structural characteristics of stainless steel castings and non-standard metal parts, and can evaluate them together from the blank, machining allowance, critical dimensions and subsequent assembly.
Casting + Machining Support
Suitable for post-processing of stainless steel casting blanks, reducing communication costs for customers with multiple suppliers.
Customization based on provided images is supported.
Processing plans can be evaluated based on 2D drawings, 3D models, or samples.
Pay attention to critical dimensions
The key control points are hole positions, threads, mating surfaces, assembly dimensions, and appearance.
Suitable for small to medium batches
Suitable for non-standard parts, small batch samples, and stable batch orders.
Common turning, milling and post-machining of castings
The specific processing method will be evaluated based on the part's structure, material, precision requirements, quantity, and surface treatment requirements.
CNC milling
Suitable for flat surfaces, steps, grooves, hole systems, and local finishing.
CNC turning
It is suitable for machining shafts, sleeves, round parts and rotating structures.
Drilling/Tapping
Supports machining of conventional threaded holes, countersunk holes, through holes, and mounting holes.
Planar machining
Used for dimensional adjustments of mating surfaces, mounting surfaces, and sealing surfaces.
Post-processing of castings
It is suitable for trimming the assembly surfaces, holes, and critical dimensions of precision casting blanks.
Pre-treatment processing
It reserves suitable processing states for surface treatments such as polishing, wire drawing, sandblasting, and electrolysis.
Covering stainless steel castings and non-standard metal parts
Evaluate materials and processing methods according to part requirements.
Commonly used materials include:
Whether a specific material can be processed depends on an assessment of the part's structure, hardness, precision requirements, and quantity.
What do we need from our clients?
The more complete the information, the more accurate the assessment of processing difficulty, pricing, and delivery time will be.
- 2D machining drawings, indicating dimensions, tolerances, threads, and surface roughness.
- 3D models, STEP/STP/IGS format preferred
- Material grade
- quantity
- Surface treatment required?
- Does the blank already exist, or is casting and machining required together?
From drawing evaluation to inspection and delivery
It's not just about whether it can be manufactured, but also whether the assembly is stable.
We don't just look at whether a part "can be manufactured," but we pay more attention to whether the subsequent assembly is stable. For parts with mating requirements, we focus on confirming key dimensions, hole positions, threads, flatness, appearance, and batch consistency.
- Size inspection
- Thread inspection
- Visual inspection
- Key hole location confirmation
- Batch sampling inspection
- Pre-packaging verification
For CNC machined parts with provided drawings, please send them to us for evaluation.
Please upload drawings, quantity, materials, and usage requirements. We will provide a quote based on the structure, precision, processing difficulty, and batch size.
