Specimen Preparation CNC Machine

TensileTurn CNC - Industrial Upgrade Model is the upgraded version of our Classic system. The system is industry leading, user-friendly round tensile sample preparation machine featuring our state-of-the-art TensileSoft and a complete Carbon software which allows the more experience operators to program the system for universal applications for cutting, sanding, knurling, drilling, facing or turning.

TensileTurn CNC - Industrial Upgrade Model can prepare standard round tensile specimens, sub-size specimens, threaded tensile specimens, button-head tensile bars, fatigue specimens and other round testing specimens. The operator is only required to simply load the machine with either round, square or irregular stock.

This machine allows your laboratory personnel to bypass any wait times with your machining center and prepare their own tensile specimens ready for testing in a matter of minutes. The production of high quality tensile specimens combined with ease of use is what sets the TensileTurn CNC apart. It enables the rapid turning of precisely measured round and button head specimens for superior tensile testing results.

What is the surface finish of the various materials that is offered by the TensileTurn CNC - Industrial Upgrade model?

The surface finish specifications are typical of a high quality CNC turning center. In the great majority of cases, the results are 63 Ra or better. There are a number of factors to consider when evaluation a surface finish. For peace of mind, it is suggested to send your samples to TensileMill CNC for our free sample preparation service. Learn more.

What are the optimal dimensions of the starting blank stock for the Industrial Upgrade tensile sample preparation system?

The Industrial Upgrade system provide the optimal output when a section of the starting blank material is in the chuck and the other end is supported by the tailstock. It is important to have enough material to hold onto by the chuck. We recommend about 1/2 - ¾" length. We especially recommend a little extra length for threaded end specimens.

Round Stock:
If you are working with round starting blanks for tensile sample preparation, the system can accommodate specimens up to 4" diameter and 12" length.

Square Stock:
If you are preparing starting blanks from square stock, the system can accommodate 1 x 1 by 12" dimensions. Additionally, our square chuck can comfortably hold on to specimens that are not 100% square. Minor deviations typically occur when an operator cuts a large sample on a band saw without precision instruments. In efforts to guarantee that our systems are the right fit for you, we always encourage our clients to send their samples to us to be prepared to give you the ultimate peace of mind. This service is completely free.

Irregular Stock:
Should your specimens have an irregular stock shape, we would require a picture to provide a custom solution to meet your short- and long-term tensile sample preparation needs. Contact us today to learn more.

What is the chip removal procedure for the TensileTurn CNC Industrial Upgrade model?

The chip removal procedure for the Industrial Upgrade tensile sample preparation machine is quite simple.
Estop the machine -> Open the door -> Remove the chips.

Safety Note:
Please wear proper personal protective equipment for handling machining chips.

Do you supply benches for your TensileTurn Industrial Upgrade Models? What are the bench dimensions?

Your bench is typically found in the optional accessory section on your Round Tensile Sample Preparation System quotation.

The bench weights 248lbs (113kg) and has dimensions of (WxDxH) 48x42x38" (122 x 107 x 97cm).

What type of fixtures / holders would I need for the system?

Fixtures and holders greatly depend on the type and symmetry of the materials of the starting blanks for your tensile sample preparation. Lathe systems have a wide variety of options available for your tensile specimens. By providing the types of materials that you are looking to prepare, our qualified CNC consultants will help recommend and supply the precise consumables for the job.

One of the values offered by TensileMill CNC is the ability to prepare your tensile specimens before making a financial investment into our systems. At that point, our production engineering team will be able to turn your samples and offer their best recommendations as to which inserts and fixtures will fit the bill. This service is offered at no cost to our clients. Contact us today to learn more.
