Unist products have had some great results throughout the industry. Don't take our word for it . . . here's what some of our customers have to say:
As a manufacture of CNC router machines supplying a wide variety of industries, we have tried a number of lubricating units. We have found the Unist lubricating system to be more easily integrated into the machine design and the support provided by Unist is very good. The units have proved to be very reliable in the field and they are well suited for continuous industrial use.- Noel A. Archie, C. Tech Coordinator: AXYZ Automation
Before we started using Coolube 2210 we were going through one gallon a week of the AccuLube, since we have been using your product we are going through one gallon every month. The life of our drills have also increased. Before the Coolube 2210 we were using seven drills per shift, currently we are using two drills per shift. Overall we are very pleased with the performance of your product.- Steve Raley, Production/Process Engineer: Buck Knives
We have had these sprayers in house now for one year we started with one, we now have four. These units have helped us increase our tool life on our Spring Generator machines by up to 60%. They have greatly reduced the heat build up in the forming process of our springs and have allowed us to reduce the number of tool changes on a run, which has allowed us to reduce our cost. The pay back on the capital expense for all four machines was less then three months. We have a total of 13 machines that we are looking at installing more of these units on as we upgrade them. When we added the units to the process we did not have to change or add any steps in our process. Parts were inspected at an outside lab to ensure they still met our specification. We passed all test with better marks then with out the units.- Dale R. Meyer, Manager Metal Fabrication & Assembly: Cherry Electrical Products
Previous to 1996 Dietrich Industries was using a number of lubrication devices on their roll forming lines. Since then we have standardized on the Unist system, primarily due to the fact that they are much more efficient in the application of lubricant. We have less run out of lubricant on the finished product and no over spray similar to the spray units that we had used in the past, providing our locations with a much cleaner environment. In addition to reducing the overall cost of lubricant we have eliminated the need for compressed air blow off nozzles on our equipment, thus reducing the cost of electrical power and reduction of noise in all of our 28 locations across the USA. We are also satisfied that the product is being metered and distributed properly to the forming rolls to reduce friction, thus prolonging the life of our tooling. In the lubrication of flat coil stock previous to the forming operation, I can truly say that we picked the right lubrication system for our equipment.- Randall A. Torok, Director of Purchasing: Dietrich Industries, Inc.
In February of 1999, We purchased our first uni-MAX Serv-O-Sprayer. We purchased the unit in hopes it would help solve a problem. We were having to run parts in a basket to let the oil drain before packaging, and reduce the amount of oil on the floor around the tapper. We started using the uni-MAX serv-o-sprayer in March of that year. The parts were much cleaner and we found that we were using much less lubricant and the taps were lasting longer. We were also able to increase our production by eliminating the need to drain the parts before packing. We updated our second tapper in February of 2000 with the same results as the first one. In September of 2000 we quoted a job that had in die tapping. We chose to try the uni-MAX Serv-O-Sprayer instead of flooding the tooling with lubricant. We tap 8 holes in a progressive die at 60 SPM. We are getting excellent tap life with this system. We also have a forming problem with a progressive die that runs .250 thick material. We had a problem keeping lube on one form station that was causing us a lot of maintenance time. We installed a uni-MAX Serv-O-Sprayer and shot a few drops or lubricant on the strip at the bend station solving the maintenance problem.- Terry Teague, Production Manager: M.S. Willett, Inc.
After looking at the data it appears we are close to 3 times the tool life. 2.0 high feed cutter went from 2 hours of insert life to almost 7 hours. 10mm ball went from 6 hours to 16 hours” "I used to buy tooling every week before installing the Revolution system. Now I buy the tooling to run the same jobs monthly." "Since we do a lot of lights out machining I used to come in to the shop in the morning to foamy overflowing coolant, since we switched to the Revolution from Unist we've had no problems.- Seth Fetty : Advance Technologies Group
I have run a test surface with your Unist spray mist oil unit with great results; I attached some pictures for your reference. We run this surface with different parameters and step over techniques using a .500 ball end mill with high Rpm and Feed rates, we found the tool condition to be still very good considering that this material was 13-8 with a Rockwell hardness of 44. The more I use this system the more I like it!” “We used a regular 1/2 diameter carbide ball end mill coated TIAN on our new HX400 Kitamura multi-axis machine with a 25000 RPM balance shrink fit holder, we rough this surface with multiple depth passes of .075 and a step over of .15 @ S6000 and a feed rate of 25 IPM. On the finishing we had a .025 depth cut all across the surface with a .007 step over with 14000 RPM and a feed of 80 ipm. Then we tried to get an even better finish so we machine 1/2 of this surface with a .010 depth cut with a step over of .003 that produced an excellent finish with 16000 RPM and a Feed rate of 120 IPM. This was a great test for us because it will introduce us to hard milling and possible new business.- Massimo Fuso : PMD Inc
The biggest benefit from the roller coater (Uni-Roller® S2), compared to our spray systems on the other presses is the ability to apply lubricant evenly on the bottom as well as the top of the material. With the spray systems, to ensure consistent coverage across the entire sheet often requires overspraying. And, even then, we’re not always able to adequately coat the outer edges of the tooling with lube, where the stock may be dry and cause premature tool wear. The roller coater performs exceptionally well, precisely, and with great repeatability - coating the top and bottom of the 17.6-in.-wide coil stock. In addition, we can customize the location and thickness of the lubricant, based on the specific requirements of the die. For example, if the die will perform a drawing operation in the center area of the die, we can program the roller coater to apply more lube in that area, and then lay down a thinner coating of lube on the outer areas of the strip. This is a game-changer for deep-draw work, to help minimize lube consumption while improving die life. The roller coater has far exceeded our expectations and has allowed us to bid on jobs we would have had to pass on before.- John Essenburg, Production Manager: Grant Industries
We recently converted two of our Hemsaw bandsaws to use the Unist Saw Blade Lube System. At first we were skeptical that they would be able to deliver the same performance as the coolant we ran previously. It's been a real shift in mindset for our operators that 'less is more' with the Unist systems. We're happy to report that we've been able to get the same or better blade life and productivity out of the Saw Blade Lube Systems while eliminating the maintenance problems we had with flood coolant. Cleanup is much easier around the saws and the shavings are nice and dry. Before the (Unist) systems, we spent a lot of money on gloves to protect us from the coolant and we've been able to eliminate that cost. We have six saws total and plan to convert the remaining four to Unist and are recommending them to our second facility.- Denver Nelms, Vice President: RHW Metals
With the Unist coolant, you can clean the saw with a vacuum cleaner. Nothing gets impacted. It's a dry chip. It's nice. The guys like it because before they'd have to wear leather aprons so they wouldn't get this flood coolant all over their clothes." "The fact that we no longer have this pile of floor dry around every saw and no coolant dripping around the shop is a small thing, but it adds up for an overall neater appearance." "One of the things that throws people off initially is the price of the lubricant, but on all these tools we run, I order a gallon about twice a year." "I wish there were more companies like Unist to work with. They're the best. Everything they do is accurate and clearly understood." (excerpts from Modern Metals Magazine's article 'Stemming the Flood' - Modern Metals, October 2012)- Rick Rankin, Facilities Leadman: Therma-Tron-X, Inc.
After changing from flood coolant to a Unist Coolubricator® and Coolube® 2210AL lubricant on our Brother TC-32A, we were able to increase our effective tap life from 450 pieces per tap to 1500 pieces per tap. The tap is an M4 x 0.7 bottoming cut tap in CF-8 stainless steel. We are happy with how clean the parts are as well but the increase in tap life is what pleased us the most.- Signicast
Until recently, all of Clover Tool’s stamping operations employed spray systems to apply lubricant, “and we sprayed everything―literally, the lubricant went everywhere,” shares Rob Zeni. “As we watched our lube costs continue to escalate over time, including costs related to disposing of spent lube, we decided early in 2018 to take action. We simply no longer could tolerate the added costs, as well as the hazards and added cleaning requirements related to excess lube on our machines, tooling and on the floor…more work for everyone. And, the air quality in the plant was less than ideal.” The solution came in the form of programmable roll-coater systems, Uni-Roller S2 models from Unist installed on 12 presses at the Concord facility (“our biggest runners,” George Zeni says), beginning in late 2018 and wrapping up toward the end of 2019. “Each system,” George explains, “features a programmable fluid controller integrated into the press controls. A key feature for us is the ability to tie the programming for each lube-system setup into the individual job recipe. The ease of setup made the project a good fit for our workplace culture—the operators immediately took ownership of the process change and appreciated the repeatability of the process. And, of course, they really appreciate no longer dealing with excess lube—on the floor, on the dies and, oftentimes, all over themselves.” “One of the most frustrating issues we used to deal with,” adds Rob, “was the constant need to tweak the spray systems, move the heads and adjust the spray pattern. We had individual units at each press with multiple sprayers and no control of the operator’s decision to use too little or too much spray. In addition, the operators sometimes would waste lubricant by not correctly placing the spray heads in their proper locations, regardless of how much training we provided. “With the roll coaters,” he continues, “we’ve eliminated all of the operator chores related to the lube system, which has reduced the time to complete die changeovers by 10 min. on average. Once the coaters are programmed for the individual job, we have absolutely zero adjustments to make.” Another advantage with the roll coaters: they apply lubricant on the top and bottom of the material, most appreciated on tools forming the toughest of materials. “We have a few jobs where our tool coatings take a lot of abuse and when using the spray-lube systems, we were forced to recoat our form tools on a regular basis,” Rob says. “With the new roll coaters, we’ve increased the number of hits between recoating the tools by 50 percent on those jobs. And, with better coating life we’ve seen less burring and die marking on the stamped parts, as well as a reduction in tool adjustments needed to accommodate dimensional issues.” Lastly, customer complaints regarding parts arriving drenched in lube had disappeared, as has most of the fumes from the facility’s weld booths, including more than a dozen robotic-welding cells and more than 20 projection-welding cells. “And, weld porosity is practically nonexistent,” says Rob. Bottom line: the new roll-coater programmable lube systems have reduced lubricant consumption by 41 percent and reduced the cost for disposal by 60 percent. Those factors alone allow George Zeni to forecast a 12- to 18-month return on investment, “not accounting for all of the other benefits,” he says. “We’ve had zero slips since the changeover, the toolmakers and operators appreciate no longer having to deal with lube-soaked tools, there’s much less cleaning required, no more dripping shop rags…the benefits are endless.” Selected portions from "Stamper Says 'So Long' to Lubricant Waste" February 2021 Metalforming Magazine- Rob Zeni, Vice President and Sales Manager: Clover Tool
In regards to the performance of Unist MQL Systems, Both Armo and Abuma believe it is an excellent product and well worth the investment. Over the past few years we have implemented Unist systems on metal cutting saws, milling and drilling machines. We have seen considerable improvements in productivity, tool life and machine cleanliness. We have been able to eliminate coolant usage almost entirely. We employ skilled Machinists and Toolmakers that have 20 plus years of industry experience that prefer this product over traditional coolants. After the initial investment the cost to operate these systems is very small. The cutting fluid is applied in very precise volumes and location on the cutting tool. Very little fluid is consumed, 4 liters of Unist Coolube under most conditions last for months. One of the most obvious advantages of Unist MQL systems over coolant is machine cleanliness. Not only does the machine stay very clean, so does the entire work area and work pieces. The metal chips are very easily cleaned up as they are not covered in sticky residues. I recommend this product. It is definitely worth a trial.- Mike Guyett, Production Supervisor: Abuma Manufacturing
