CNC Machining Services for Bar & Tube Components
Fraser Steel has spent more than 55 years machining tubular products to close tolerances and complex finishes. Our investment in automated CNC machining lets us turn raw bar and tube stock into a finished, inspection-ready part in a single continuous cycle.
High-Volume CNC Machining on the Sinico Top 1100 CNC Plus
We run the Top 1100 CNC PLUS from Sinico, a rotary transfer machine designed for automatic cutting and end machining of bars and tubes. It processes raw stock into precision-finished parts up to 550 mm long at rates of up to 2,600 finished pieces per hour, all under CNC control.
Machines at this scale represent a serious capital commitment. The Top 1100 alone weighs 17,000 kg and draws 100 kW installed. For machine shops and OEMs that need the output but not the overhead, we are the fabrication partner with one already on the floor and running every day.
| Specification | Value |
|---|---|
| Throughput | Up to 2,600 finished pieces/hour |
| Part diameter | 6–115 mm |
| Finished part length | 10–550 mm |
| Loadable bar length | 3,000–6,000 mm |
Operations We Perform in a Single Cycle
The Top 1100 completes the full machining sequence before a part leaves the machine. Because every operation happens in one pass, dimensional relationships between features hold across the entire production run.
- Chamfering — angled transitions at edges and bore openings for clean assembly and safe handling
- Facing — square, flat end surfaces that establish the datum for every downstream feature
- Drilling — through-holes and blind holes positioned under program control
- Threading — internal and external threads cut to specification
- Turning with a static piece — cylindrical profiling performed while the workpiece stays fixed and the tool rotates
- Boring — enlarging and finishing internal diameters to tight bore tolerances
- Forming — profile geometry cut with dedicated form tooling
- Marking — part numbers, lot identification, and orientation marks applied in-cycle

Frequently Asked Questions
What is CNC machining?
CNC machining is a subtractive manufacturing process in which computer-controlled tools cut material away from raw stock to produce a finished part. At Fraser Steel, our automated systems quickly and consistently produce complex, tight-tolerance components from bar and tube.
What makes the Sinico Top 1100 CNC Plus beneficial for my project?
The Top 1100 CNC Plus is a rotary transfer machine capable of producing up to 2,600 finished pieces per hour. It performs the full machining sequence in a single continuous cycle, delivering faster lead times, tighter tolerances, and part-to-part consistency across long production runs.
Which machining operations can you perform in a single cycle?
Chamfering, facing, drilling, threading, turning with a static piece, boring, forming, and marking, all completed before the part leaves the machine, with no secondary setup required.
What types of features can Fraser Steel machine into my parts?
Our CNC machining capabilities support chamfers, counter-bores, ID and OD grooves, complex depth angles, face knurls, radii, shoulders, threads, and specified finishes. If your part requires intricate or multi-step details, send us the print and our team will review it.
What part sizes can you machine?
The Top 1100 handles part diameters from 6 to 115 mm and finished part lengths from 10 to 550 mm, fed from bar stock up to 6,000 mm long.
Can Fraser Steel help me optimize my part design?
Yes! With over 35 years of experience in tubular manufacturing, our engineers collaborate with customers to refine part designs that improve performance and reduce costs.
