EXAKT Cutting and Grinding devices don’t cut with a sharp sawtooth blade, but cut and grind with minimal thermal and mechanical stress on the sample. The EXAKT CP (Contact Point) process ensures pinpoint application of energy. Even in complex components with materials of different hardnesses, the cut is guided precisely while the sample surface quality is left unimpaired.
EXAKT Cutting and Grinding Technology enables you to approach sample examination in ways which simply weren’t possible for your application until now. Long service life, reliability, and minimal service expenditure also contribute considerably to the economical use of our systems.
› Almost no burring, fraying or tearing out on the cut surface
› Safe operation – Minimal risk of the operator being cut
› Coplanar cuts with very tight tolerances
› Flexible and very precise alignment of the samples
› Cutting process for a wide variety of different materials, composites and components
› A variety of options for sample support
Don’t take chances when handling rare or unique samples. Mistakes in the preparation process delay your work and can provide false results. That’s a risk you shouldn’t take. Trust the decades of experience with globally tried-and-tested thin section cutting technology from EXAKT. We guide you through the sample preparation process, which helps your unique research results.
The EXAKT 312 Diamond Band Saw was developed to meet the special requirements of pathology and anatomy (human and
veterinary) medicine. With the EXAKT 312, even the smallest cuts down to about 1 mm can be made freehand with almost no risk of cuts to the operator. Whether it’s soft tissue, bones or implants in the bone-tissue composite, it can all be cut effortlessly and quickly. Not
only this, but it does it with a cut surface quality surpassing every other process available. An initial assessment of the cut can generally be made right away. Outfitted with a variety of different options, the EXAKT 312 can be adapted to individual handling and operating comfort needs.
The EXAKT 312 is very easy to operate and clean. Band changes can be made without tools or adjustment. The stainless-steel housing is consistently designed for good water and tissue drainage. For thorough cleaning and disinfection, modules can be quickly removed without the use of tools.
The EXAKT 312 Diamond Band Saw doesn’t cut, it grinds very precisely. This is the reason for the outstanding surface quality
of the cut surface. Complete preservation of the sample with a surface free of artifacts, micro-fractures and breakouts enables
immediate inspection and assessment of the sample. Even the cell information of very different tissue densities remains
intact. Since the cutting band grinds rather than cuts, there is no immediate risk of injury to the operator in case of inadvertent
contact, which is a first in work safety! Tricky samples with implants, in particular, can be precisely
and safely processed. Guiding the cut is easy and precise, and the process is clean and quiet. Water cooling also reduces dust
development and ensures that the sample doesn’t overheat.
› Superior cut surface quality
› Maximum working safety enables cuts down to 1 mm
› Integrated water cooling prevents overheating of the sample, reduces dust development and keeps the cutting band cleaner
› Cutting band changed without tools or readjustment
› Fast and easy cleaning through the tool-less removal of contaminated modules
› Reliable and time-tested – Hundreds of systems are already in use around the world
Cosmetic Manufactures Use EXAKT Three Roll Mills For Brilliant Colors
When it comes to color brilliance, color effects and high color intensity, EXAKT Three Roll Mills offer significant advantages. For example, the primary particles are not damaged during the processing of metallic and effect pigments. Optimal process control and reproducible quality are a matter of course with EXAKT Three Roll Mills. They satisfy the strictest guidelines for quality assurance and are therefore GMP and ISO auditable. Major companies and brands benefit from EXAKT Three Roll Mills in the production of lipsticks, eyeliners, foundations and nail polishes.
For everyday cleaning between formulations, alcohol and a soft cloth or paper towel are the best things to
use. Do NOT spray the alcohol on the rollers or pour the alcohol into the gap when the machine is
running. Put the alcohol on a paper towel or cloth and hold it against the roller tightly while you turn the
roller with the hand wheel.**
When you start to get a build up, you can use an abrasive to clean the rollers. You don’t want to do it too
often because it will remove some of the porcelain over time. Everyone has their favorite product so I’m
going to tell you about several of them.
1. Do not use Ajax or Comet cleansers (even SoftScrub). They have bluing crystals that can leave
blue dye on the roller. If you can find a form of SoftScrub that is made of completely white
powder this will be fine. I personally use Bon Ami cleanser. You can find this in the grocery store
with the other cleansers. I make a slurry of it with either water or Goo-Gone (a citrus based liquid
that cuts oils) and I put it on the tip of a sponge and gently scour the rollers. Other people use
baking soda in a light oil to do the same thing. It is possible to put some of these slurries or Soft
Scrubs in the back gap and run the mill. One or two passes are fine, but if you run it a lot you will
create larger pores in the porcelain.
2. There is a product called Fast Orange Hand Cleaner. You can find it at Wal-Mart, Sam’s,
Home Depot, auto parts stores etc. It’s a pumice based hand cleaner that is the consistency of
jelly. You can use this as well. When we have a particularly badly stained roller, we will run it
through the mill with the gaps slightly open. One pass usually takes off any stain or congealed
product. Do NOT use this for more than one pass. The pumice is much more abrasive than the
cleanser or baking soda. You can put a little on a damp sponge and spot clean with it gently.
Once you’ve done any of these, you should thoroughly clean the rollers with soap and water and then
remove that residue with alcohol before running a new product.
** Many pharmacies are running back-to-back ointments and need to clean their mills quickly.
So rather than turn the rollers with the hand wheel they leave the machine running while they
clean. Not only is this unsafe for the technician, but it makes it easy to get the cleaning cloth
caught in the gap. When this happens, there is a risk not only to the technician but to the
machine and its precision. It is possible to bend the shafts of the rollers if something too big
is pulled in and the repair/replacement can be costly.
