Product Description
Service Process for Custom CNC Milling Steel Toothed Presser Feet
1. Pre-Production Collaboration
(1) Requirement Confirmation
Communicate with customers to confirm presser foot specifications, including tooth density, overall dimensions, mounting hole position, material requirements (e.g. high-hardness steel), order quantity, and delivery schedule.
(2) Drawing & File Review
Receive CAD models or 2D technical drawings with tolerance notes, especially for critical features such as tooth spacing accuracy and mounting interfaces.
(3) DFM Evaluation
Conduct Design for Manufacturing analysis to ensure the presser foot structure is suitable for CNC milling. Optimize tooth geometry and mounting design for compatibility with industrial sewing machines.
2. Process Planning & CNC Programming
(1) Material Selection
Select suitable materials such as high-carbon steel, stainless steel, or alloy steel based on wear resistance, working environment, and load requirements.
(2) CAM Programming
Develop precise CNC milling toolpaths to machine tooth profiles, frame structure, and mounting holes in a single setup for consistency and efficiency.
(3) Machining Simulation
Run CNC machining simulations to prevent tool interference and ensure uniform tooth dimensions across the entire batch.
3. Production & Quality Control
(1) Machine Setup
Fix steel blanks securely on CNC milling machines and calibrate dedicated cutters for tooth machining.
(2) CNC Machining
Perform automated CNC milling to complete tooth formation, body structure, and mounting holes in one continuous process.
(3) Inspection & Testing
Inspect tooth spacing, hole positioning, and overall dimensions using calipers and gauges. Conduct spot checks for wear resistance to ensure long service life.
4. Post-Processing & Delivery
(1) Surface Treatment
Apply anti-rust oil or protective coating to improve corrosion resistance during storage and use.
(2) Cleaning & Packaging
Remove machining residues and pack each presser foot in protective, anti-collision packaging.
(3) Delivery
Ship products according to agreed logistics methods. Small batch orders (≤50 pcs) typically have a lead time of 5–7 days.
Common Materials for CNC Milled Steel Toothed Presser Feet
1. High Carbon Steel (45# Steel)
Description:
The most commonly used material for industrial sewing presser feet.
Characteristics:
After heat treatment, it offers high hardness and excellent wear resistance. Suitable for long-term friction with thick materials such as leather and canvas. Easy to machine with CNC milling for precise tooth profiles.
Application:
Used for the main body of standard industrial toothed presser feet, ensuring durability and structural stability.
2. Stainless Steel (304 / 303)
Description:
Optional material for environments requiring corrosion resistance.
Characteristics:
304 stainless steel provides good rust resistance for humid workshops.
303 stainless steel offers improved machinability, allowing higher precision tooth spacing and smoother CNC milling.
Application:
304 for high-humidity environments.
303 for applications requiring high tooth accuracy to prevent material slippage.
3. Alloy Steel (40Cr)
Description:
High-performance material for heavy-load applications.
Characteristics:
Higher strength and toughness than standard carbon steel. Improved wear resistance after heat treatment. Suitable for high-pressure sewing conditions.
Application:
Used for heavy-duty presser feet on industrial sewing machines handling very thick materials such as luggage leather.
