Product Overview
The SG01M is a semi-automated spiral stitch sewing machine designed for buffing and polishing wheel manufacturers. It handles thick, medium, and thin sisal and fabric materials with consistent stitch quality. The machine uses a single-needle, oscillating shuttle system with synchronized upper and lower feeding to form a 2-thread lock stitch. It is built for low cost and high efficiency, supporting the 'One-Worker-Multiple-Machine' concept. It is used in the sewing step of buffing wheel production, following fabric or sisal preparation and preceding pressing or trimming.
Key Benefits
- Reduces labor cost by enabling one operator to manage multiple machines
- Sews thick, medium, and thin materials without skipping stitches or puckering
- Maintains alignment between upper and lower layers during long or viscous sewing runs
- Adjustable needle position and three-part tooling for dust-proof strip sewing
- Lifting feeding tooth and alternation presser keep material stable during sewing
- Connecting-bar take-up mechanism improves arm shaft speed and reduces noise
Application Scenarios
- A buffing wheel factory replacing manual sewing benches with semi-automated machines
- A manufacturer adding spiral-stitch wheels to their product line without high capital outlay
- A workshop with limited space needing a compact, low-cost sewing solution
- A production line upgrading from hand sewing to machine-assisted sewing for consistency
Who It Is For
- Buffing and polishing wheel manufacturers
- Small to mid-sized abrasive product makers
- Workshops producing custom or low-volume buffing wheels
- Factories aiming to reduce labor cost in the sewing stage
Problems It Solves
- Manual sewing leads to inconsistent stitch quality and high labor cost
- Hand sewing cannot keep layer alignment during long or viscous runs
- Sewing thick material causes skipped stitches; thin material causes puckering
- Lack of machine support limits production scalability and repeatable output
- High-cost machines are not viable for low-margin production environments
Technical Features
- Single-needle, oscillating shuttle with 2-thread lock stitch
- Upper and lower synchronized feeding system
- Lifting feeding tooth and alternation presser for material stability
- Manual presser can be moved forward, backward, left, and right for positioning
- Adjustable needle position for dust-proof strip and three-part sewing
- Connecting-bar take-up mechanism for faster arm shaft speed and quieter operation

Manufacturing And Process
Step 1
Prepare the fabric or sisal stack for sewing, following bias cutting or rolling
Step 2
Load the material into the machine and position the presser foot
Step 3
Set the needle position and adjust the feeding mechanism for the material thickness
Step 4
Engage the clutch motor and begin sewing with the connecting-bar take-up mechanism
Step 5
Use manual presser movement to reposition material during long or complex runs
Step 6
Complete the spiral stitch and remove the sewn wheel for pressing or trimming
Quality Control
- Stitch consistency checked during sample runs before shipment
- Free sample testing available on buyer's own material
- Clutch motor ensures smooth start and stop without thread breakage
- Lifting feeding tooth and alternation presser tested for alignment stability
- Noise and vibration levels monitored during operation to ensure long-term reliability
Customization Options
- Needling distance can be customized beyond the standard 5 mm
- Needle model and position adjusted for specific material thickness
- Power supply voltage configured for destination market (e.g. 220 V or 380 V)
- Machine can be quoted as part of a full production line including CRA-500, CRA-800, CRA-600, CRA-700
Compared With The Alternatives
| Fully Automated Sewing Machine | The SG01M is semi-automated and lower cost; choose it for budget-conscious production, not for high-speed, fully automated lines |
|---|---|
| Manual Sewing by Hand | Hand sewing is slower, inconsistent, and requires more labor; the SG01M reduces labor cost and improves stitch uniformity |
| CRA-900 High-Speed Sewing Machine | The CRA-900 is fully automated and faster; the SG01M is a low-cost alternative for smaller or mid-sized operations |
Use Guide
- Ensure the fabric or sisal is properly aligned before starting the sewing process
- Adjust the needle position and presser foot for the material thickness to avoid puckering or skipping
- Use the manual presser movement to reposition the material during long or curved stitches
- Keep the clutch motor engaged for smooth start and stop during continuous runs
- Contact us on WhatsApp for the English operation video if the operator is new to spiral stitching
