Evidence reviewed September 19, 2026. Choosing a CNC tube bender requires more than comparing a model number or maximum outside diameter. The useful question is whether the exact machine, tooling and quoted configuration can produce your part from your material to your acceptance criteria.

This guide provides a practical framework for comparing Pedrazzoli Bend Master machines with equipment considered from Crippa/OCTA, BLM, AMOB, Universal Tool & Engineering, transfluid, Hines, VLB, Horn, Tube Form Solutions, Unison, YLM, Pines, Trick-Tools and Winton. It is not a ranking. Product specifications change, and names in this article include manufacturers as well as sales or integration channels. Confirm the current specification and quote scope directly with each supplier.

Compare the Process, Not Just the Badge

A published maximum capacity is an initial screening point, not proof of application fit. A complete comparison should identify:

Material and starting condition: alloy, yield strength, temper, seam condition and surface requirements.
Tube envelope: outside diameter, wall thickness, centerline radius, straight lengths, bend angles and rotations.
Bend quality: allowed ovality, wall thinning, wrinkling, marking and dimensional tolerance.
Process requirements: clockwise or counter-clockwise bends, fixed or variable radii, number of tooling levels, mandrel and wiper-die needs, boost and early mandrel extraction.
Production workflow: changeovers, loading and unloading, inspection, operator touches, cycle expectations and part-family mix.
Quoted scope: required options, tooling, software, freight, rigging, commissioning, training, warranty and service response.

Three Pedrazzoli Bend Master Reference Points

Model	Published U.S. capacity	Published control	Important configuration note
Bend Master 45	1.75 × .118 in.	10 electric controlled axes, plus one optional axis	Published for clockwise and counter-clockwise bending in the same cycle and 3+ tool stacks.
Bend Master 65	2.5 × .083 in.	10 electric controlled axes, plus one optional axis	Published for clockwise and counter-clockwise bending in the same cycle and 3+ tool stacks.
Bend Master 90	3.5 × .157 in.; material basis is not stated beside this capacity	6 electrically controlled axes	U.S. specification publishes clockwise bending and 3+ tool stacks. Its architecture is not the same as BM45/65 and its U.S. specification also lists a hydraulic reservoir for auxiliary functions.

Capacity qualification: The global BM90 statement is 90 × 4 mm in steel R=400 N/mm². Keep that statement separate from the U.S. 3.5 × .157 in. statement because the material basis is not printed beside the U.S. capacity. Do not transfer BM45/65 ten-axis or same-cycle clockwise/counter-clockwise claims to BM90.

Build a Fair Shortlist

Start by separating direct nominal-size matches from smaller and larger neighbors. A machine with an 80, 83 or 88.9 mm published maximum does not cover a full 90 mm requirement. A larger 100 or 102 mm machine may cover the diameter, but it can bring a different footprint, cost structure, tooling envelope and process architecture.

Direct or Nominal 90-Class Evidence

YLM CNC-90MS-6A: the manufacturer publishes 90 × 2.6 mm mild steel at 1.5D CLR and identifies a hybrid electric/hydraulic family architecture.
Universal Tool & Engineering US90ED-4A and US90MS-5A: 90 mm / 3.5 in. OD is published, with double or multi-stack tooling and left- or right-hand configurations. Wall and material basis should be confirmed.
Pines CNC090: an official flyer publishes material-specific rows, but current commercial status and an inch/metric inconsistency in the stainless row should be resolved with a signed current datasheet.

Smaller Neighbors Are Not Full 90 mm Substitutes

Examples include BLM ELECT80, AMOB eMOB 80, Crippa/OCTA 980LE, transfluid PROLINE 80, Unison Breeze 80 mm, VLB EB83CNC and the SOCO SB-90x4A-2S offered through Tube Form Solutions. The SOCO model name includes “90,” but the published diameter is 88.9 mm. These machines may fit a particular part, but they should not be described as equivalent to a full 90 mm envelope.

Larger Machines Require a Different Economic Review

Relevant larger neighbors include BLM ELECT102, Crippa/OCTA 100HE, AMOB eMOB 100, transfluid PROLINE 100, Horn Metric CNC 100TBRE, Hines 300 CNC-B and VLB EB105CNC. Larger nominal capacity does not establish a better fit. Compare published wall and material basis, machine architecture, tooling, utilities, floor space and the complete quoted package.

Understand Manufacturers and Sales Channels

Brand lists can accidentally count the same equipment twice. Tube Form Solutions is a distributor and integrator channel that offers equipment including SOCO. Trick-Tools is a retail channel and should not be counted as a second transfluid manufacturer when it lists transfluid equipment. Winton’s published CNC rotary-draw range reviewed for this guide did not establish a 90-class model. Channel capability still matters—local application review, tooling, installation and service can affect the result—but channel and OEM evidence should be labeled separately.

Use a Common-Part Trial

A fair machine comparison uses the same material lot, blank length, geometry and acceptance criteria. Before the trial, document:

Material certificate, OD, wall and starting condition.
Every CLR, angle, rotation and straight length.
Acceptable ovality, wall thinning, wrinkles, marks and dimensional tolerance.
Required bend directions, tooling levels and variable-radius sections.
Production quantity, part-family mix and changeover expectations.
Inspection method and who accepts the result.

Record the installed tooling, software revision, machine configuration, cycle assumptions and operator interventions. A sample produced on a specially equipped demonstration machine may not represent the base configuration in a commercial quote.

Questions to Put in Every CNC Tube Bender RFQ

What exact model suffix and market configuration are quoted?
What material, yield strength, OD, wall and CLR support the published capacity?
Is the machine supplied clockwise, counter-clockwise or capable of both directions in the same part cycle?
How many tooling levels and fixed or variable radii are included?
Which axes, boost functions, mandrel features and automation are standard, optional or application-specific?
What utilities, foundation, cooling, guarding and material handling are required?
What tooling, simulation, programming, training and commissioning are included?
What are the warranty, parts availability, remote-support and field-service terms?

Request an Application Review

Bring the finished part drawing, material, tube OD and wall, centerline radii, bend sequence, tolerances and production requirement. Pedrazzoli USA can review the Bend Master application path and quote scope. Apply the same evidence standard to every supplier on the shortlist.

Official Sources and Further Verification

No affiliation with the other named brands or channels is implied. Specifications and commercial status should be reconfirmed with the manufacturer or authorized seller before purchasing.
