Hack Sawing Machine GL7132
The GL7132 is the smallest of a three-model hydraulic hack sawing range that runs GL7132, GL7140 and GL7150. It cuts round stock to 320mm, squares to 290x290mm and will take a 45 degree oblique cut up to 220mm diameter, so it handles the heavy bar and section that a bench-size saw cannot reach.

What This Machine Does
The GL7132 is the smallest of a three-model hydraulic hack sawing range that runs GL7132, GL7140 and GL7150. It cuts round stock to 320mm, squares to 290x290mm and will take a 45 degree oblique cut up to 220mm diameter, so it handles the heavy bar and section that a bench-size saw cannot reach. Drive and feed are hydraulic rather than mechanical, which means feed pressure stays steady through the cut instead of falling off as the blade loads up, and it is one of the reasons the machine is straightforward to keep running. Apart from clamping and feeding the material, the cutting process is automatic, and the machine carries a safety guarantee device so a fault in the cycle stops the stroke rather than running on. Bow reciprocation runs at 34, 60 or 84 strokes per minute from a 3.44Kw motor, with a 600x50x2.5mm blade. The machine weighs 1100kgs, which is mass that stays put while the bow works.
Why Buyers Choose This Machine
- Hydraulic drive holds feed pressure steady through the cut instead of falling away as the blade loads
- 320mm round and 290x290mm square capacity takes heavy bar a bench saw cannot reach
- 45 degree oblique cutting to 220mm diameter without moving the work to another machine
- Cutting process runs automatically once the material is clamped and fed
- Safety guarantee device stops the cycle rather than letting a fault run on
- Three bow reciprocation rates of 34 60 and 84 per minute match stroke rate to material
- 1100kgs machine mass damps the stroke so cuts stay square on heavy sections
Where Hack Sawing Machine GL7132 Earns Its Place
Problems It Solves
- Mechanical feed loses pressure as the blade loads so cut times drift on heavy sections
- Angled cuts on heavy section get transferred to a second machine or done by hand
- An operator standing over a long heavy cut is wasted labour
- A saw without a safety device keeps stroking through a jam and breaks blades
- A light machine chatters on heavy bar and the cut face goes out of square
Who It Is For
- Machine shops working with heavy bar beyond bench saw capacity
- Forging and heat treatment shops preparing billets
- Steel stockholders cutting to customer order
- Fabricators needing repeatable mitre cuts on heavy section
- Distributors supplying hydraulic sawing machines to heavy engineering workshops
Application Scenarios
- Cutting heavy round bar for forging and shaft work
- Sizing large square and rectangular billets for a machining cell
- Angled 45 degree cuts on section for fabricated frames
- Stockholder cutting of customer lengths from mill bar
- Preparation of heavy stock in a die and mould shop
- Stepping up to GL7140 or GL7150 where the same shop also runs larger diameters

How It Is Built and What Can Be Changed
Operations Performed
- Sawing
- Cut-off
- Oblique sawing at 45 degrees
Quality Control
- Hydraulic circuit pressure tested and checked for leaks before shipment
- Safety guarantee device triggered and confirmed to stop the cycle
- All three bow reciprocation rates run under load
- Vice squareness and 45 degree oblique setting checked against a test cut
- Motor running current and machine noise checked during the test run
Customisation Options
- Model selected from GL7132 GL7140 or GL7150 against the largest section you cut
- Supply voltage phase and frequency built for your market
- Saw blade size and tooth pitch matched to your material
- Coolant supply arrangement specified with the machine
- Manual and machine markings prepared in your working language
How It Compares With the Alternatives
| G7016 mechanical hack saw machine | The G7016 is a light machine for stock up to 160mm; the GL7132 runs hydraulic feed at over twice that capacity and takes angled cuts |
|---|---|
| GL7140 and GL7150 in the same series | Same hydraulic machine scaled up. Choose the model by your largest round: 320mm 400mm or 500mm |
| Band sawing machines | A band saw takes a narrower kerf and cuts faster; the GL7132 has fewer wearing parts in the cutting system and a blade that a shop fitter can change without setting band tension |
Running the Machine
Step 1
Clamp the material in the vice and support long heavy bar behind the machine
Step 2
Set the vice to 45 degrees if you are cutting a mitre and check the section is within Dmax 220mm
Step 3
Select the bow reciprocation rate that suits the material and section
Step 4
Check blade tension and hydraulic oil level before starting
Step 5
Start the cycle and confirm the first cut for length and squareness
Step 6
Let the automatic cycle run out the batch clearing swarf between pieces
Step 7
Check the safety guarantee device periodically as part of routine maintenance

Questions About Hack Sawing Machine GL7132
Which model of the three should we buy?
Go by your largest round bar. GL7132 cuts to 320mm, GL7140 to 400mm and GL7150 to 500mm. Send us your stock list and we will confirm which one covers it without paying for capacity you will not use.
Can it cut at an angle?
Yes, 45 degree oblique cutting. On the GL7132 the maximum diameter at that angle is 220mm. The larger models take 250mm and 300mm respectively.
How heavy is the machine for shipping?
GL7132 is 1100kgs, GL7140 1200kgs and GL7150 1450kgs. Overall dimensions for the GL7132 are 1940x835x1345mm; we supply the crated dimensions with the order.
What motor power does it need?
3.44Kw on the GL7132 and 4.34Kw on the GL7140 and GL7150. Tell us your supply voltage phase and frequency and the machine is wired for it.
What blade does the GL7132 take?
600x50x2.5mm. The larger models take 650x50x2.5mm and 750x50x2.5mm. We match tooth pitch to the material you cut, so tell us what you are working with.
What are your payment and trade terms?
FOB CFR and CIF. Payment is 30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
Is maintenance complicated because it is hydraulic?
No. The hydraulic circuit is laid out for easy maintenance and the routine work is oil level, filter and blade changes, which a shop fitter can do.
