The MINI is compact, but it is powerful enough to take on the task with its triple sample fixture. The fixture aims to maximize the efficiency of production and minimize human intervention. It allows you to stack thrice the usual number of samples that you prepare. All you need to do is click the chosen setting option, which is provided by the software. The operator can start the machine to commence the preparation, and then move on to do other tasks. The tensile specimens should be ready by the time he comes back.

The MINI has 200-240V voltage tolerance. You can use a step-down converter when you wish to bring down voltage and a step-up converter when you wish to elevate voltage. Stepping up or stepping down depends on the electrical requirements of your facilities.

Both models have several technical differences that you see in the comparison table, which you can obtain upon request. The major differences between the two models include costs, volume capacity, and size. Between the two, the MINI is smaller in size that's just right for small to medium scale of sample preparation. It is also a more affordable solution if used as standalone equipment for tensile sample preparation.

You can make a full upgrade to turn your TensileMill CNC MINI into an extremely cost-effective solution when it comes to preparing tensile samples. You can request for a detailed quotation to know more about the flat tensile preparation machines and determine the best one for your facility.

The 10-gallon re-circulating water-based coolant comes standard with the MINI. The coolant has been formulated based on the particular materials that must be cut. We recommend brands like Blaser, Hocut, and Cim Cool for the preparation of tensile specimens as well as other CNC machining needs.

The flat tensile specimen prep systems, including the TensileMill CNC MINI, can prepare the tensile specimens from sheets and strips. To save time, it is best to prepare tensile dog bone samples from sheets. However, you can still prepare specimens from strips if you prefer it that way. Take a look at these options:

- First Option

You may cut the tensile specimen blanks initially into strips before loading them into the clamping fixture, which comes with the unit. Try cutting down the specimens to 2-inch thickness (or less) to make it work more efficiently. You may load up to half-inch thick specimens per clamp, then get them all ready in a single cycle.

- Second Option

You may cut the tensile specimens directly from the sheets. The custom clamping fixture setup, which is included in all standard quotations, allows you to cut from the sheet tops. This gives you the advantage of preparing some specimens from one sheet in a single cycle. The number of specimens that you can cut depends on the size of the sheet that you are using.

The main difference between cutting from sheets and cutting from strips is the manner the cut is created. For sheets, the cuts start from the top, then the outline is made. For strips, the cuts are made from the specimens' side. If you prefer to cut from sheets, you need to inform our technical team regarding the dimensions of the sheet that you want to use.

You can hasten the preparation when you stack your tensile samples. The TensileMill CNC MINI has a clamping device that makes it possible to stack the tensile samples, which could be of any material, for fast preparation. You can stack samples with a thickness of 1-inch and below using the clamping device, which can hold the specimens firmly in place. This allows the machine to run smoothly and produce perfect tensile samples. If you have unique specimens, there are available specialty clamps that you can use. You can visit our site to know more about the quick tensile sample preparation or you may also request a quote.

The TensileMill CNC MINI tensile preparation machine has taken the market by storm. The huge volume of orders that the company continuously receives is causing some delays in the expected delivery of the unit. You can contact us first to know how fast we can ship your MINI to your facility.

The triple-position clamping fixture base comes standard with the MINI. It has a one size clamp for every position that lets the user mill at least 3 samples at once. The maximum length of starting samples that the turnkey solution allows is 12 inches. There are also available custom solutions.

Additionally, the unit also comes with endmill and ER collet that you can use for a long time. If you need additional endmills, ER collet, clamping fixtures, and base fixtures, you can submit a request to order anytime.

Sometimes, you need a little bit of trial and error to find the material's feed rate and optimal speed. Of course, it is necessary to use the right endmills that your material is compatible with. This process may take a while but will still not consume too much of your time. TensileMill CNC MINI Inc. offers free tensile dog bone preparation as one of the unique benefits.

All you need to do is send the specimens to us. Our engineers are the ones who prepare the specimens. They can usually identify the feed rate and suitable speed on the second or third cycle run. Once the specimens are prepared, our technical engineers will present to you the most fitting recommendations. Also during the training and installation process, we cover the feed rate and speed optimization to ensure that you will be able to perfectly prepare your tensile specimens each time.

You can prepare both tapered edge and regular (standard) tensile specimens. We have clients who prepare tensile dog bones based on the standards of ASTM and ISO. See the illustration below to serve as guide:

This is a floor-standing system, which can be installed according to your preference. We suggest tilting the machine slightly to the front right side to gain a more efficient circulation of the fluid.

An open roof is provided to this enclosed unit. You may choose to put a hood range over the unit if you prefer - it is not mandatory to do so.

It is recommended to have starting blanks that are almost as thick as the net size. This means each clamping fixture can easily accommodate blank widths of 38mm or 1.5 inches thick. In case your sample is wider, you can consult our staff in the engineering section to get the best solution for the milling process.

The MINI has a standard spindle between 1.5kW and 2hP. If you are going to use a tougher material for tensile sample preparation, the ISO 20 spindle can give you the optimal benefit. This gives you a choice between 2.2kW and 3hP. You can actually prolong the lifespan of your machine even if you are milling materials that are tough.

To give you an accurate quantity of specimens that you can prepare in one cycle, you should speak with one of our Product Consultants to further discuss your application. The material's thickness, hardness, and type are the things that affect the time it takes to finish the machining process as well as the quantity of flat tensile milling samples. You are welcome to call us today or submit your request for further details.

When you purchase your TensileMill CNC MINI you will also receive the clamp fixture and designated endmills as part of the standard package. The soft and hard materials require different endmill bits. The engineers of TensileMill CNC MINI present the most suitable endmill bits recommendation according to the hardness or softness and type of material that you'll use. This also includes the total milling volume.

All endmills are uniquely designed and created to address the need to prepare tensile samples. This makes up for a longer or superior lifespan for each unit as compared to the other endmills in the market.

The average cost of endmills per bit is between $35 and $80. There are also bulk options that can save you more money. You can directly buy the bits from TensileMill CNC. You can request a quote today when you want to buy the consumables you need.

The tooling fixtures, which receive proper maintenance, are created to last for decades. During the one day installation and training, our engineers will provide proper guidance and knowledge to your operators regarding the preventative maintenance.

There are several ways to troubleshoot your compact flat tensile sample preparation system's coolant pump. First, take a look at some of the reasons the coolant system may be causing trouble:

  1. The motor may overload due to a jammed pump impeller or the resistance to turning is too much. The corrosion from sitting idly, sludge build-up, etc. could be the culprit.
  2. The problem could be due to a wiring problem from the breaker to the pump. If there is a bad connection or the wire is chafed, a short could occur and cause the breaker to trip.
  3. Although it is not common or likely to happen, an issue in the internal motor might also cause some problems.

Before the units leave the facility, they are all tested for function and also during installation. There is highly likely an issue with the unit when it is running and pumping liquid for 10 seconds, especially if it has not been running for quite a while. We recommend submerging the belt in fluid during the time when it is sitting idle. You may contact us right now so we can assist you and bring light to the questions that you have in mind.
