The Importance of Properly Maintained Grinding Oils

Vomat systems provide micro filtration to particle sizes of 3 to 5 microns. 

An often overlooked variable of grinding precision tools is maintaining your grinding oils. This is important because coolants minimize friction and eliminate excessive heat at the point of contact between the wheel and the tool. During the machining process, grinding oils are contaminated by metal debris, dirt and decomposition stemming from extreme heat exposure. When coolants are not thoroughly filtered, it is necessary to change them often.

Optimally filtered coolants, however, have two main positive effects on the production of cutting tools: They improve grinding economy, and they enable tool manufacturers to produce high-quality products.

According to Steffen Strobel of Vomat, a manufacturer of fine filtration systems, the requirements for high-quality tools are constantly on the rise and, therefore, tools must be ground with much more precision. To achieve this, manufacturers are investing in modern machinery and climate-controlled production facilities. Given this kind of expenditure, there is no room for cheap compromises when it comes to coolant filtration, he says. The coolant must have a high degree of purity since coarse particles can interfere with the grinding process and prevent the manufacture of tight-tolerance tools.

To improve grinding oil maintenance, Vomat offers its FA series of fine filtration systems. The series is designed to provide full flow (non-bypass) filtration of clean oil, which is tailored to the needs of the production machines. The filter cartridges are automatically cleaned with 100 percent separation of clean and dirty oil. The filters’ capacity, combined with the on-demand backwash cycle, are designed to increase service life of the metal coolant. This not only prevents loss of tool quality, but also saves money on metal coolants, the company says. Coolants don’t have to be changed as often either.

March 2015 Digital Edition Now Available

The digital edition of Modern Machine Shop's March 2015 issue is now available.

The digital March 2015 issue of Modern Machine Shop is now available. The cover story discusses the evolution of micromachining and some lessons one shop in particular has learned along the way. Other stories discuss how advances in wire EDM technology have made it acceptable for machining critical aerospace parts, how a job shop relying on homegrown talent was able to win aerospace and defense work while expanding its five-axis capabilities, and how additive manufacturing already plays a major role in aircraft production.

Our Rapid Traverse section takes an in-depth look at spindle housings and motors, an automotive cylinder coating for high-production applications, and a multi-axis workholding system that uses a three-side dovetail.

This month’s Better Production section explores how a shopfloor CMM reduces production bottlenecks, how in-house CNCs helped an automotive shop gain manufacturing control, and how one shop used CAM software as the key to its continuous improvement efforts.

The Modern Equipment Review section highlights machining centers.

Now Is the Time to Register for Amerimold

Looking for a mold manufacturing event to attend this summer in the Midwest? Well you’re in luck. Exhibit hall and technical conference registration is now open for Amerimold 2015, which will take place June 17-18 at the Donald E. Stephens Center in Rosemont, Illinois.

The annual event is presented by Gardner Business Media, in partnership with Modern Machine Shop, and its sister publications MoldMaking Technology, Plastics Technology and Automotive Design and Production. The event connects more than 2,500 of the top owners, executives and engineers involved in the plastic injection mold manufacturing industry. It includes an exhibit hall, technical conference and production sourcing opportunities.

Pre-registration extends through May 1 and includes:

  • Complimentary Amerimold exhibit hall access
  • Discounted technical conference registration
  • Free show floor education sessions
  • Onsite business development opportunities 

Amerimold visitors will see the latest machine tools, materials, tooling, software, services and components for mold manufacturing. In addition, new this year, Amerimold will co-locate with the leading injection molding conference, Molding 2015

Case Study: Chip Conveyor System Saves Floor Space

Hennig Inc. put together this video case study that shows how Advanced Machine and Engineering used the Hennig CDF (chip disc filtration) system to effectively remove chips when cutting tombstones and save floor space.

About 34 seconds into the video, Brad Patterson, director of operations and continuous improvement at Advanced Machine and Engineering, says AME purchased a Toyoda machine to improve on-time delivery of workholding products. Since the machine can run lights-out, it was important to make sure the total package—including the chip conveyor—was working as needed.

What’s special about this particular application is that floor space was a major constraint. Also, the machine is used to cut cast iron, steel and aluminum materials, producing anywhere from cast fines to long, stringy chips. According to Scott Cooley, business unit manager – chip conveyor and filtration systems at Hennig, AME needed a hinged belt conveyor system as opposed to the standard scraper design. By using the Hennig CDF, the company was able to save more than 2 feet of space from the standard design.

GE Aviation Inspection Technologies Challenge Announced

NineSigma, representing the General Electric Company, is accepting entries for its Inspection Technologies Challenge through February 24. This challenge is designed to find technologies, processes or approaches that can greatly increase the speed and accuracy of aviation parts inspection and greatly increase manufacturing efficiency.

Participants will compete for as many of three cash prizes of $15,000. Winning respondents who enter into a joint development agreement with GE will be awarded a $35,000 development grant to collaborate with GE to develop proposed solutions.

For this challenge, participants are asked to demonstrate their abilities by inspecting a Victorinox 4 inch paring knife instead of actual high-precision aircraft parts.

Visit this site for more information about the challenge and read the official rules. There is also a forum in which you can post questions about the challenge.
