Tube Cutting & Straightening Machines
Prepare tube lengths for forming and assembly.
BOBO supplies coil-fed tube straightening and chipless cutting machines, copper and aluminum tube saws, and dedicated capillary processing equipment. Selected machines add insulation insertion or capillary end forming and coiling. Standalone straighteners and specialist laser equipment serve other preparation tasks within the range.

DEFINE THE CUT END
Match the cutting method to the tube stock and the next operation. Length, bore opening and end shape belong in the sample check.
FIND YOUR MACHINE
Compare the incoming stock and the required cut.
For coil stock, start with the tube material, straightening system and cutting method. Compare saw cutting separately from rotary chipless cutting, then look at dedicated capillary and insulation-inserting models if the part needs further processing. The steel wire cutter supplies condenser wire, while the standalone pipe straighteners correct tube or bar stock without cutting it. The evaporator laser machine addresses a separate hole-cutting task.

PARTS & APPLICATIONS
Tube blanks and prepared assemblies
A cut tube may move next to bending, end forming, joining or insulation assembly. The cut length and end condition should suit that next operation; a nominal cutting tolerance alone does not describe the finished blank.
01
Condenser and evaporator tube blanks
Cut copper, aluminum or steel/Bundy tube to the required length before bending or joining. Material-specific machines and clamping arrangements prepare the blank for the downstream tube process.
02
Copper capillary components
Dedicated equipment straightens and cuts small copper capillary tube from coil. The integrated model adds end forming and coiling for parts that need those features in the same processing sequence.
03
Insulated air-conditioning connection tubes
A dedicated insertion machine combines tube preparation with fitting the insulation sleeve. Coiling, fitting nuts and forming connection ends must be planned as their own operations in the line arrangement.
SELECTION GUIDE
Select the cutting route around the next operation.
Material grade, wall thickness and incoming stock form determine how the tube is fed, straightened and clamped. The required end condition then separates the cutting options. Review the bore, roundness and end face as well as the length, especially where a small tube will be joined or formed next.
01
Match the machine to the incoming stock
Identify the material and condition, diameter and wall thickness, then distinguish coils from straight lengths. Coil-fed processing needs straightening and controlled feeding; a standalone pipe straightener serves a different task from an integrated tube cutter.
02
Define the cut end that the next process needs
Compare rotary chipless and saw-cut samples for length, bore opening, roundness and edge condition. For evaporator hole cutting, evaluate the laser process separately. The accepted sample should reflect the actual material and the later forming or joining operation.
03
Compare the full cycle and included stations
Balance cut length, feeding, clamping and collection when assessing output. Independent dual lines can serve different settings; dedicated capillary or insulation machines add specific operations. Separate machine speed from the output of the complete production sequence.
A cut-to-length machine prepares the blank. Include bending, end forming, coiling or insulation work in its scope only when the selected machine provides those stations; otherwise plan the transfer to separate equipment.
YOUR FINISHED PART
Start with your product drawing.
Include the material, dimensions and acceptance requirements.
From technical review and testing to delivery and after-sales.
Evaluate the cut end with your production material.
BOBO can review the tube drawing and stock, propose the cutting and clamping arrangement, and plan sample checks before delivery. For combined processing, define the station sequence and the handover to the next machine. Include feeding equipment, collection, tooling changes and training in the agreed project scope.

BEFORE YOU CHOOSE
Before you choose a tube cutting machine
Compare the actual cutting mechanism, feeding arrangement and included stations before using speed or accuracy figures to shortlist a model.
How does rotary chipless cutting differ from saw cutting?
The listed rotary chipless machines cut around the tube and separate it with a controlled pulling action. A saw removes material through the blade cut. The mechanisms leave different end conditions, so the choice should reflect the tube material, wall thickness and next operation. On the dual-line machine, the cutting arrangement is a configuration choice; its product name alone does not establish which cutter is supplied.
Does chipless cutting mean no end finishing is ever needed?
No. Chipless describes the cutting route, not an unconditional finished-end specification. A sample check should cover bore opening, end deformation, roundness and the edge condition required for the next operation. Any deburring, sizing or other end finishing should follow the accepted part requirement rather than an assumption based on the word chipless.
What is the advantage of two independently controlled lines?
Separate servo-driven lines allow different cut lengths or feed settings within the selected machine’s range. This can help when two tube specifications are needed for the same assembly or when producing different orders. Compare finished pieces over the complete cycle, including feeding and collection; two stations do not by themselves guarantee twice the daily output.
Can cutting be combined with end forming, coiling or insulation insertion?
There are dedicated combinations. The integrated capillary machine includes straightening, cutting, drawing-specific end forming and coiling. The insulation-inserting machine combines tube preparation with sleeve insertion, while its described coiling equipment is separate. A basic cut-to-length machine does not include these operations, and nuts or flared ends must be listed as distinct requirements in the proposed process.
Do the standalone pipe straighteners also cut the stock?
No. The construction-pipe straightener repairs bent steel pipe, and the nine-roller machine straightens metal pipe and bar. They differ from the coil-fed machines that combine straightening and cutting. The steel wire cut-to-length machine is also a separate application: it prepares wire for wire-on-tube condensers, not hollow tube blanks.
START WITH A DRAWING OR SAMPLE
Share the tube stock, cut length and end requirements.
Send the material grade and condition, outside diameter, wall thickness, length range and tolerances. State whether the material arrives in coils or straight lengths, and include batch sizes, target output and requirements for the cut face, bore and surface.
For combined processing, add the end-form drawing, capillary coil dimensions or insulation sleeve specification, and identify the machines already available for the next operation.
