How do I trouble shoot the coolant pump on my TensileMill CNC MINI?

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.

Can I use TensileMill CNC MINI to Prepare Tensile Specimens from Sheets of Metal or Other Materials?

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.

tensilemill-cnc-mini

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.

What are the benefits of upgrading to ISO 20 Spindle?

The standard spindle on the MINI is 1.5kw - 2hP. If you have tougher material applications for tensile sample preparation, the upgraded spindle is the optimal choice for you.
