The system comes with an interlock mechanism to keep the door closed during the operating proceed. As an additional safety measure during the flat tensile sample preparation procedure, the opening of the door during the operating cycle triggers an emergency stop event and the machine stops.

There are a number of factors that determine whether your material may have some burr after the tensile sample preparation system completes the cutting cycle. The factors include type of materials, condition of tooling, feed, speed, etc. Based on our experience, the burr ranges can be significantly reduced or eliminated by applying the right combination of feed/speed rate and the proper tooling. TensileMill supplies our clients with a starter pack of tooling for the optimal burr proof results.

Should burr be inevitable, there are additional options to deburr your tensile specimens to be prepared for tensile testing. These options include including files, knives, deburring tools, tubing, grinders, flap wheels, abrasive pads, and more. Learn more by requesting a quote or contacting our CNC consultants today.

There are a number of ways to trouble shoot the coolant pump on your compact flat tensile sample preparation system. Here are some of the reasons the coolant system may be giving you a hard time:

1. Pump impeller is jammed or there is too much resistance to turning and as a result the motor is overloading. This could be due to sludge build up, corrosion from sitting, etc.

2. Wiring issue from the breaker to the pump. If a wire is abraded or there is a bad connection there could be a short that is causing the breaker to trip.

3. Internal motor issue. Not common or likely, but it is a possibility.

These are all tested for function prior to leaving our facility and during install. If it is running and pumping fluid for 10sec then I bet the issue is highly likely. Especially if it has been sitting idle for a long time. We always recommend that the belt is submerged in fluid during the periods of not running.

Finding the optimal speed and feed rates for a given material sometimes requires a little bit of trial and error. It is of course important to use the correct endmills compatible with your materials. With that said, this process will not be all too time consuming. One of the unique benefits offered by TensileMill CNC Inc. is for our clients to send their specimens to us for a free tensile dog bone preparation. When our engineers are preparing your specimens, a lot of the times we are able to identify the correct speed and feed rate on the 2nd or 3rd cycle run. Once the tensile specimens are prepared, our technical engineers will offer our best recommendations for you. Additionally, we cover the speed and feed rate optimization during the training and installation process to guarantee that your tensile specimens are prepared perfectly every time.

Our TensileMill CNC MINI and all other flat tensile specimen preparation systems are capable of preparing tensile specimens from strips and from sheets. In efforts to save additional time for sample preparation, preparing tensile dog bones from sheets is an excellent and a time effective strategy. Whether you prepare specimens from strip or prefer to prepare specimens from sheets, we got you covered. Please refer to the two options below:

Option 1:
You may cut the starting tensile specimen blanks into strips and load them into our Triple Clamping Fixture that comes standard with the unit. This works great if you have no problems cutting the specimens down to 2" thickness (or less). You would then be able to load up to 0.5? thickness worth of specimens per clamp and prepare them all in one cycle.

Option 2:

You may be cutting the tensile specimens from your sheet materials directly. All standard quotations include our custom clamping fixture set up that will allow you to cut your tensile dog bones from the top of the sheets. This way you can program to prepare a few specimens from a sheet in one cycle go. The amount of specimens will depend on the size of your sheet.

The primary difference between cutting from strips vs. cutting from sheets is the way the cut is made. For strips, the cuts are made from the side of the specimens. For sheets, the cuts are made from the top of the sheet first and then the outline of the specimen is created.

Should you prefer to prepare specimens from sheets, simply let our technical team know what sheet dimensions you would like to use.

Our TensileSoft™ allows to prepare both regular (standard) and the tapered edge tensile specimens with a push of a button. A number of our clients who prepare tensile dog bones according to ASTM and ISO standards as for a tapered edge finish. An example of tapered edge specimens would be certain figures of ISO 527 and ASTM D638. These are demonstrated below:

TensileMill CNC MINI is capable of easily preparing such specimens within a 0.5? thickness. Learn more by requesting a free quote or contacting us today.

The MINI tensile sample preparation machine has a voltage tolerance of 200-240V. The system should not be stepped down to 110v. It is below the system?s voltage cut-off for most of the components and therefore the machine will not run with a 110v input.

TensileMill CNC MINI can be quoted with a vise option making it possible to prepare Charpy impact specimens with standard or sub size dimensions. It is worth noting that an experienced operator would be necessary for the job.
