Miller - Shortage of Skilled Welders
The solution to the chronic shortage of welding operators isn′t as simple as training a person to weld, particularly in industry-specific environments. See how two large companies have examined welding training issues and implemented progressive strategies for serving their long-term welding and training needs.

Through-the-Tool Coolant Delivery

One of the most effective ways to deliver coolant to the cut is through the tool that is making the cut. Through-the-tool coolant delivery technology is available for drilling and milling with solid tools, and for cutting tools that use inserts. Those tools must be matched with toolholders that will allow the technology to be effective, and working fixtures that will keep the part in place while allowing the coolant and chips to be evacuated.

Coolant-through parting/grooving system
Iscar Metals Inc. (www.iscarmetals.com) has introduced a line of inserts that provide through-the-insert coolant capabilities. The company's Jet-Cut system is available as an upgrade to its Do-Grip parting inserts. The system has a coolant hole that passes through the insert to an outlet near the cutting edge. DGNC inserts are for parting and grooving operations on stainless steel and high temperature alloys. The company says applying coolant through the Jet-Cut system reduces flank and cratering rates and reduces production of long and tangled chips when cutting titanium and austenitic stainless steels.

Techniks CoolFLEX Tool Holders
Techniks Inc. (www.techniksusa.com) developed a new line of toolholders that provide machinists the ability to switch coolant paths from coolant-thru-spindle to DIN style coolant by removing two setscrews. The company says the switching feature on its CoolFlex toolholders can save thousands of dollars compared to the cost of tooling both coolant-thru and DIN coolant spindles.

Collets for Through-Coolant Tooling
Rego-Fix (www.regofix.com) offers CF coolant flush collets that the company says can be used with its powRgrip toolholding system, and the company says they are compatible with its PG 10, PG 15 and PG 25 series of toolholders. CF collets have three equally staggered serrations that allow coolant to be flushed along the sides of tools and to the tips of cutters to eliminate unwanted chip particulate.

Cool Drilling
Making productivity gains in drilling holes may not seem to be the most challenging machining problem, but there are three factors above all others that can affect drilling speed, tolerance and tool life:
  1. Coolant
  2. Spindle speed and feed rate
  3. Rigid toolholding
Coolant keeps the tip of the drill at a relatively low operating temperature and helps to extend tool life. The build up of heat in a hole can cause the tip of a drill to curl, dulling its cutting edge and causing it to plow through a workpiece. That could cause the drill to break in the hole. "Some people think that cooling is the only function of coolant," but it plays other roles, said Gregory S. Antoun, president of ChipBlaster (www.chipblaster.com).

Multiple Workholders Fit VMC
Providing 43 X 22 X 22-in. travels (X/Y/Z), the A-3 VMC handles large workpieces as well as multiple workholders containing small parts. Its 12,000-rpm CT-40-taper spindle uses P4 angular-contact bearings and a floating drawbar that reduces bearing pressure during tool clamping/unclamping.

Holemaking Trends Run Deep, Fast, and Dry
Holemaking, arguably the most basic of metalworking processes, is one area where shops can greatly improve returns on machine tool investments. It's easy to see how when one considers that 50 to 70% of all production time is spent making holes. Even small process improvements can boost production and drive down costs. However, the three holemaking techniques offering perhaps the greatest production gains are drilling more precise deep holes, drilling more holes in less time, and drilling dry.

Makino
Makino— a leading manufacturer of horizontal and vertical machining centers and EDM machines — has announced a new series of online Webinars. Designed for shops of all types and sizes, the seminars are free to anyone who registers. The planned seminars are intended for shops in the automotive, aerospace, medical product and die and mold industries. In addition to metal cutting and die/mold, the seminars will cover new technologies, such as micromachining. Mark Rentschler, marketing manager, says, "Online seminars allow anyone with an Internet connection to attend without losing a day of work." The seminars concentrate on shop efficiency, lean manufacturing, asset utilization, machine tool integration and automation, machine tool technologies, and metal cutting processes. Makino's application engineers, product managers and guest speakers will give presentations. Click here for more info on upcoming seminars and registration information.
