What standards can be programmed into the TensileMill CNC XL flat tensile preparation?

The user-friendly, intuitive software that comes standard with TensileMill CNC XL allows the operator to use the machine as both a tensile sample preparation and a standard automatic CNC machine. Common ASTM, ISO, DIN, and JIS standards are pre-programmed into the software prior to dispatch. At any time the user may add additional parameters using the convenient 21" LCD touch screen with a sample picture. Simply enter the correct measurements near the correct part of the tensile specimen and the machine will do the rest. The tensile parameters will be saved for future use and can be accessed with a single click of a button. Learn more about TensileMIll CNC XL by contacting our qualified CNC consultants today.

What is the maximum hardness value of tensile specimens that can be prepared on TensileMill CNC XL?

Depending on the tooling and material in question, specimens with hardness value up to 40 HRC can be milled with a no-frills package. Once the hardness value moves up to 45-50 HRC certain upgrades are required. These upgrades include special tooling and programming. It goes without say that the thickness of the tensile samples plays a large role in this. Contact our CNC consultants today to provide all of your technical requirements to receive an accurate quotation.

What extra steps can I take to prolong the life of my tensile sample preparation machine?

Following the basic preventative maintenance procedures is the general rule for most all quality control equipment. A special recommendation is to keep your unit clean and keep the lube tank full. Contact us should you have any further questions.

What comes standard with TensileMill CNC XL sample preparation machine?

The XL a specialty unit that can be customized to your specific needs. The base price of the machine includes the turnkey solution based on your technical specifications.

Where can I acquire additional spare parts and consumables for my tensile specimen preparation machine?

What volumes of tensile sample preparation can the TensileMill XL handle on daily basis while maintaining maximum machine life longevity?

TensileMill CNC XL is a robust tensile sample preparation machine. The unit is designed to run 24-7 with only the consumables being a thing of attention. Just like any machine, preventative maintenance is an essential part of prolonging the unit's lifespan. Be sure to read the manuals and follow instructions accurately to get the maximum use out of the equipment for many years to come. Contact our engineering team today should you have any questions.

Where can I acquire additional spare parts and consumables for my tensile specimen preparation machine?

TensileMill CNC XL will be supplied with all your necessary end-mills and tooling fixtures for long term operation. Additional end-mills and fixtures can be easily acquired from TensileMIll CNC requesting a quote today.

Though the tooling fixtures are designed to last a lifetime with proper maintenance, additional fixtures can also be purchased down the road.

How many tensile specimens can I prepare at any one time?

In order to pinpoint the quantity of specimens that can be prepared in one cycle, we advise that you speak with our Product Consultants to further discuss your application. Flat tensile milling quantity of samples and the time it takes to complete the machining process will depend greatly on the material type, the hardness and thickness of your material.
