Two Roll Hydraulic Thread Rolling Machine

The Two Roll Hydraulic Thread Rolling Machine from Industrial Machinery Corporation (IMC) forms external threads on suitable cylindrical bolt, rod, bar and fastener blanks. Manufactured in Ludhiana, India, this hydraulic thread roller uses two circular dies to displace material rather than remove chips.

Applications and forming method

A 2 roll thread rolling machine must be selected against the finished component drawing and material condition. Circular die thread forming requires suitable blanks and matched dies. Confirm material grade, hardness, prepared diameter, thread profile, pitch and formed length before selecting a configuration. Knurling or other profiles require a separate tooling review.

Compare the model range

The specification table lists IMC-25, IMC-40, IMC-50, IMC-80, IMC-100 and IMC-120. Compare maximum pitch, infeed and through-feed diameter, forming length, force, die dimensions and motor power for the intended job. Limits in separate rows are not a simultaneous operating point. Ask IMC to confirm the combination required for your component.

Infeed and through-feed requirements should be discussed separately. Specify the required formed length and whether the job requires an end stop, long-bar support or handling of repeated batches. Check the proposed die setup against the component geometry and available space. Do not select solely by the largest published diameter.

Prepare a component enquiry

For a Two Roll Hydraulic Thread Rolling Machine enquiry, send a drawing, blank dimensions, material grade and hardness, thread standard and pitch, tolerance and daily quantity. Include the finished length and inspection requirements. State batch size, expected changeover frequency and whether more than one profile is required. These details help identify appropriate tooling and accessories.

Request a trial using representative blanks when evaluating output. Total cycle time includes handling, forming, inspection and any changeover. An advertised capacity does not establish a production rate for every material or part. Agree the output assessment method and acceptance conditions before committing to a production plan.

Manufacturing and inspection

IMC manufactures this equipment in Ludhiana, Punjab, India. The existing product information describes testing before dispatch. Ask which manufacturing and inspection checks apply to the proposed model and which records are available. Specify the gauge, dimensional tolerance and surface finish required for acceptance. Confirm whether a sample demonstration can be arranged for your job.

Installation, commissioning and support

Confirm electrical supply, site preparation, handling and installation requirements with IMC. Ask the quotation to define commissioning and operator training, including the operating and maintenance instructions supplied. Obtain the applicable warranty period, exclusions, service support process and spare-die availability in writing. These terms depend on the agreed supply scope.

For safe operation, follow the supplied instructions for guarding, workholding, lubrication and maintenance. Plan the handling of long bars and keep measurement and adjustments separate from operation. Ask which routine checks, consumables and maintenance intervals apply to the selected configuration.

Price and quotation requirements

The final price depends on the model, tooling, accessories and optional configuration. Request an itemised quotation identifying the supplied die set, motor and electrical specification, optional equipment, packing, freight and delivery time. Confirm installation, training, warranty and support terms separately. Use the Quote List or contact IMC with component details for an application-based quotation.

For cut threads, compare the bolt threading machine and rod threading machine. For hollow pipe components, review the three-roll hydraulic model and its pipe-specific requirements.

Reading the capacity table

IMC-25 lists a 2.5 mm maximum pitch, 25 mm maximum infeed diameter, 16 mm through-feed diameter and 80 mm infeed length. IMC-120 lists an 8 mm maximum pitch, 125 mm maximum infeed diameter, 76 mm through-feed diameter and 150 mm infeed length. The intermediate models provide additional combinations; review each column against the actual component rather than combining unrelated maximum values.

The table also identifies spindle and pump power separately. Discuss the total electrical requirements and starting arrangements with IMC and the site electrical team. Check die outer diameter and bore against the proposed tooling, including whether existing dies can be used. Compatibility should be confirmed from actual dimensions rather than a model name alone.

When reviewing a trial, agree which characteristics are measured and how samples are selected. Record the material and prepared blank used, the profile and pitch, the setup and inspection result. Ask for clarification of any variation before approving the configuration. Keep the accepted component drawing and supply scope with the purchase records.
