CK01 or CK02? Choosing a horizontal press for 40×10 and 50×10 mm flat bar

For cold bending and cutting 40×10 mm flat bar, the CK01’s listed capacity covers that section. If your work requires 50×10 mm flat bar, consider the CK02. Confirm the material grade, finished geometry and tooling before choosing either machine. The CK02 provides 16 tons of force compared with the CK01’s 8 tons, but the documented processing limits do not all increase in the same proportion.

Define the stock and operation first

Start the comparison with your commonly used stock and the largest section your actual orders require. Specify flat bar width and thickness separately. Include the material grade, state that the work will be processed cold, and identify whether the requirement is bending or cutting. A single maximum dimension does not provide enough information to select equipment for every operation.

The CK01 and CK02 are horizontal hydraulic machines that accept different attachments in front of the piston for coving, motifs and bending work. Cutting requires the appropriate cutting die. When comparing packages, ask the supplier to identify the attachment needed for your part alongside the machine itself. Seeing a motif in a catalog does not establish that its physical tooling is included.

The flat bar increase is in width

The CK01 lists cold bending capacities of 40×10 mm flat bar and 25×25 mm square bar. Its listed cold cutting capacity is 40×10 mm flat bar. For the CK02, both cold bending and cold cutting limits are 50×10 mm flat bar. The listed cold bending limit for square bar remains 25×25 mm. Do not treat that square bar bending figure as a square bar cutting specification.

Both flat bar examples are 10 mm thick. The documented difference is that the CK02 handles a wider flat bar at that thickness. Selecting the 16-ton model therefore does not establish twice the capacity in every section or suitability for any thicker stock. If your required section is not explicitly listed, request confirmation against the material and finished-part details.

• CK01: cold bending and cutting of 40×10 mm flat bar.
• CK02: cold bending and cutting of 50×10 mm flat bar.
• Both models: a listed cold bending limit of 25×25 mm square bar.

Check motor and frame data against the installation

The CK01 has a listed motor power of 4 kW and a weight of 450 kg. The CK02 lists 7.5 kW and 500 kg. Both specify a 380 V, three-phase electrical supply. Use these details when discussing electrical infrastructure and moving the machine into the workshop. Motor power alone does not establish actual energy consumption or the energy cost of a finished part.

Both machines have listed dimensions of 163×53×116 cm. These are machine dimensions, not the total working area required. Include the direction of long-stock movement, the space occupied by finished parts, operator access and maintenance clearance in the layout discussion. Identical external dimensions do not prove that the same arrangement will suit every part you intend to make.

Separate physical tools from drawing files

Both models list a large coving die, a small coving die and a cutting die. They also list an AutoCAD drawing file containing 25 different plasma-ready designs. That file is not a delivery of 25 physical dies. Ask the quotation to distinguish attachments supplied ready for use from designs that would require additional manufacturing.

Collar cutting and bending dies are listed as optional. If this operation is part of your purchasing requirement, have the necessary tooling identified as a separate item in the machine quotation. If you plan to reuse existing tools, send their mounting dimensions and drawings. The ability to accept different front attachments does not establish direct compatibility with every tool already in your workshop.

Do not infer finished output from tonnage

The CK02’s greater force does not, by itself, establish higher daily output. Both catalog specifications list 5,000 pressing operations per eight hours. Do not treat that figure as confirmed output of your own finished, acceptable parts. The number of operations needed for each component and the tooling used must be clarified when evaluating the quotation.

Send the supplier a representative part and the scope of work alongside your daily quantity target. Explain whether an order involves both cutting and bending, how much the products vary, and which jobs require tooling changes. This keeps the selection discussion tied to your actual work rather than an assumption that greater pressing force automatically means faster production.

Use the same information for comparable quotations

Request quotations for both models against the same part list. Include frequently used sections as well as the largest one, since tooling requirements do not depend only on maximum stock size. Show the required shape and acceptance criteria on the finished-part drawing. If sample evaluation is proposed, agree beforehand which material and operation the result must represent.

The final quotation should distinguish standard tools, optional attachments, electrical requirements and delivery scope. Request the warranty period and exclusions in writing as well. Evaluating the CK01 for work within its 40×10 mm flat bar limit and the CK02 for work requiring 50×10 mm flat bar gives the technical confirmation process a concrete starting point.

• Material grade, stock cross-sections and the requirement for cold processing.
• Bending or cutting operation, finished-part drawing and required quantities.
• Standard and custom tools required, plus details of existing attachments.
• Workshop electrical supply and the proposed material handling layout.

Frequently asked questions

Do I need the CK02 if I only process 40×10 mm flat bar?

That section falls within the CK01’s listed cold bending and cutting limits. Stock size alone does not make the CK02 necessary. Confirm the material grade, part geometry and tooling suitability before deciding.

Can the CK02 bend larger square bar?

The supplied catalog lists the same 25×25 mm cold square bar bending limit for both machines. The CK02’s higher tonnage does not establish a larger square section limit. Request separate technical confirmation for a different section.

Does the AutoCAD file come with 25 physical dies?

No. The file contains drawings for 25 designs. The physical tooling list includes large and small coving dies and a cutting die. Collar cutting and bending dies are optional; confirm the exact delivery scope in the quotation.
