What This Machine Does
The GZ4233 is a double column horizontal band sawing machine for cut-off work on round material up to 330mm, running a 4115mm band. Feed speed is under hydraulic control with stepless regulation, so the operator sets feed to the material rather than choosing from fixed steps, and can back it off when the band enters a hard section. Clamping can be manual or hydraulic, which suits shops that cut both one-off pieces and repeat batches on the same machine. Small material can be bundled and cut in one pass, so a bundle of small bar or tube goes through as a single cut instead of piece by piece, which is where the machine earns its time back in a fabrication shop. The band is guided on antifriction bearings with hard alloy guides, and that guiding is what extends band life: the band is held rather than rubbed, so it stays sharp and tracking true for longer. The machine is classified under HS heading 8461.
Why Buyers Choose This Machine
- Bundle cutting puts a group of small bars or tubes through in a single pass instead of one at a time
- Stepless hydraulic feed regulation lets the operator tune feed rate to the material mid job
- Manual or hydraulic clamping so the same machine suits one-off cuts and repeat batches
- Antifriction bearing and hard alloy band guiding extends saw blade service life
- Double column head keeps the band square through the full depth of a 330mm round
- Band consumable cost stays predictable because the guides do not scrub the band
Where Double Column Horizontal Metal Band Sawing Machi Earns Its Place
Problems It Solves
- Cutting small tube one piece at a time wastes most of the cycle on loading
- Fixed feed steps mean a compromise setting that is wrong for half the stock list
- Band blades wear out early where guiding scrubs rather than supports the band
- Hydraulic-only clamping is slow for a single off-cut and manual-only is slow for a batch
- A single column head lets the cut face wander on a deep round
Who It Is For
- Fabrication shops cutting quantities of small section and tube
- Machine shops preparing round stock for turning
- Steel stockholders serving mixed customer orders
- Maintenance workshops that cut both single pieces and small runs
- Distributors supplying band sawing machines to general engineering
Application Scenarios
- Bundle cutting of small tube and bar in a fabrication shop
- Cut-off of round material up to 330mm for machining stock
- Mixed one-off and batch cutting in a jobbing workshop
- Stockholder cutting of customer lengths
- Cutting stock where band life has been the main running cost problem

How It Compares With the Alternatives
| XAIMC hack sawing machines | The band saw cuts faster with a narrower kerf and will bundle cut; the hack saw is simpler but puts every small piece through individually |
|---|---|
| G4250 double column band saw | The G4250 takes 500mm sections and runs hydraulic clamping only; the GZ4233 is the lighter machine with manual clamping available for quick one-off cuts |
| Abrasive cut-off of small tube | Abrasive cutting burns the tube end and is one piece at a time; the GZ4233 bundles them and gives a clean face ready to weld |
Running the Machine
Step 1
Load the material, or stack a bundle of small section squarely in the vice
Step 2
Choose manual clamping for a one-off cut or hydraulic clamping for a batch
Step 3
Set the feed speed using the stepless hydraulic regulation, starting low on a new band
Step 4
Check band tension and that the guides are running clean before starting
Step 5
Make the first cut and inspect the face for squareness and finish
Step 6
Run the batch and clear swarf from the guides between cuts
Step 7
Inspect the hard alloy guides periodically as band life depends on them

Questions About Double Column Horizontal Metal Band Sawing M
What is the largest round it will cut?
330 mm round material. Tell us the largest section on your stock list and we will confirm the machine covers it.
Can it really cut a bundle of small bars at once?
Yes. Small materials can be bundled and cut together, which is where this machine saves the most time in a fabrication shop. Send us a typical bundle size and we will advise on clamping.
How long does the saw band last?
That depends on your material, feed rate and coolant. The antifriction bearing and hard alloy guiding is designed to prolong band life by supporting rather than rubbing the band. Tell us your material and cut volume and we will estimate band consumption.
Is clamping manual or hydraulic?
Both are available on this machine. Manual is quicker for a single cut; hydraulic is the one you use for a batch.
What band length does it take?
4115mm. Tooth pitch is chosen against your material and section, so tell us what you cut and we will quote bands with the machine.
How is it shipped and what terms do you offer?
Crated for sea freight on FOB CFR or CIF. Ask for crated dimensions and weight at order stage so your forwarder can book space.
What are your payment terms?
30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
