Apps make it easier to run good parts faster
Okuma America Corp. offers its new App Store at www.myokuma.com. Applications created by Okuma developers, distributor developers and members of Partners in THINC are available for CNC functionalities that reportedly increase productivity and streamline machine tool processes. Okuma's THINC-OSP CNC makes it possible to use apps, because the control is built using a Windows-based open-architecture platform that allows users to easily install PC applications, according to the company. Most apps are available free of charge. One app, for example, monitors the machine alarm status and automatically sends an email, text or phone message to the user when alarm condition is activated. Users also have the ability to create and share apps they develop themselves or in conjunction with their distributors.
Solid-carbide drill with radial-margin land design
Walter USA LLC introduced the Walter DC170 solid-carbide, internally cooled drill for drilling ISO-P and ISO-K materials. It has a land design that orients the margins radially and a copper-color finish (DPP coating). The design of the lands improves the drill's performance, based on their shallow cooling grooves at the drill end, according to the company. The coolant flow encompasses the entire drill point, cooling both the drill and the workpiece interface, and inhibiting chip packing. The new drill's design features also adds more material behind the cutting edge, improving stability. The alignment of the new lands-design results in smoother drill operation, reducing vibration to a minimum, which also enhances hole quality, according to Walter. Which is initially offering the DC170 in sizes of 16 and 20 times diameter.
Wire EDM is targeted for aerospace work
GF Machining Solutions' CUT 200 Dedicated wire EDM has a built-in tilt/rotary table for cutting complex aerospace components, such as turbine discs, using B-axis rotation and a +/-20° A-axis tilt. The machine also incorporates on-machine, in-process inspection, which encompasses a measuring probe and supporting software. The latest generation of the company's spark generators allows the machine to vaporize at up to 38 sq. in./hr. (400 mm2/min.) and produce tapers up to 30° in the Z-axis height. This is achieved while imparting fine surface finishes and eliminating recast layers and microcracks—critical requirements for aerospace parts. To significantly reduce noncutting times, the wire EDM offers fast axis speeds and quick wire threading, according to the company. In addition to the aerospace industry, other suitable markets for the machine include mold and die, medical and contract manufacturing.

Methods Machine Tools Inc. offers the YASDA YBM 7Ti 5-axis HMC for machining heat-resistant materials, such as titanium and Inconel. According to the company, the machine has a unique rotary table design that offers four times the rigidity compared to other tables. Positioning accuracy on the X, Y and Z axes is +/-0.005 (0.0002") and is ±1 second (measured in degrees) on the rotary and tilting A/B-axis. The machine has a 25-ton, H-shaped steel base for enhanced rigidity, absorbing cutting forces and minimizing vibration. Hardened, ground and lapped guide ways enable rapid feeds up to 48 m/min. (157.5 sfm), yielding high accuracy throughout every full stroke. To maximize performance levels, all linear axes are hand-scraped, and the mating faces of the guide ways are about double the width of conventional designs. The HMC comes with a 10,000-rpm, 50-taper direct-drive spindle and a 240-tool capacity automatic toolchanger.
Miniature clamping nut is slip-proof
Rego-Fix Tool Corp. has introduced the Hi-Q/ERMX miniature clamping nut for applications on Swiss-style automatic machine tools. The nut has an antislip locking design engineered to prevent the locking wrench from slipping off the nut during assembly and disassembly of ER collets. The nuts can replace any brand of older-style miniature nuts and are available in ER 16 and 20 sizes in standard and through-coolant versions. Frontal milled slots on the OD of the nut mate with corresponding features of the wrench to prevent slippage when tightening and loosening a nut. The nuts have a special surface treatment for increased clamping force and a coating that prevents corrosion. Benefits include enhanced operator safety and prevention of damage to other tools, according to the company.
Grinding machine has two rotary hydrostatic turrets
The Landis Twin Turret grinding machine from Five Landis Corp. features two rotary hydrostatic turrets with integral servomotors and X-axis hydrostatic ways with linear motor infeed. The grinder can handle workpieces with a swing up to 180mm (7.1") and lengths up to 400mm (15.7") using CBN wheels up to 350mm (13.8") in diameter and 40mm (1.6") wide at wheel speeds up to 120 m/sec. (393.7 sfm). It can perform eccentric and concentric multiple-axis contouring in various traverse configurations with optical levels of precision, according to the company. The design eliminates mechanical backlash through the use of linear and radial servomotors for all motions, and achieves high system stiffness and damping with hydrostatic spindle bearings. The grinder has a 1,125mm (44.3") load and access height. This enhances ergonomics and makes it easy to integrate with standard industrial robots for parts loading and unloading, eliminating the need for special automation or a gantry system in many applications.
Blow-off gun cleans without compressed air
Specialized Safety Products' Jet-Kleen personal safety blow-off gun delivers a high volume of air at the relatively low pressure of 3.0 psi (207 mBar) to remove residue such as dust, fiber and water from people, surfaces, components or work environments. Available in portable and wall-mounted models, the blow-off gun requires virtually no maintenance and consumes less energy than high-pressure air compressors, according to the company. All models feature a flexible, heat-resistant hose for easy control in all work environments and a foam-insulated interior to ensure noise levels do not exceed 78 dB.
Virtual reality enhances remote monitoring
Indiana Technology and Manufacturing Cos. has made use of wearable monitoring systems to enhance its remote monitoring capabilities. The Oculus Rift virtual reality headset, currently in development, allows stereoscopic 3D vision and real-time head motion, allowing users to view all parts of a 3D model, while the Leap Motion gesture-control sensor can enable operators to interact with the model in real time. To illustrate the capabilities, ITAMCO allowed attendees at IMTS to drive a virtual forklift around a simulated warehouse course via the Oculus Rift, awarding a Leap Motion controller to the fastest time and shirts to all finishers. In addition to the Oculus Rift, ITAMCO Technology Manager Joel Neidig said the company recently began utilizing Google Glass for remote monitoring as well.
Industrial vending system maximizes storage space
The new TX750 vending system from AutoCrib Inc. utilizes a rolling dual tambour-style door that can open to any specified size to dispense standard and other maintenance, repair and operations items without repackaging them. Using a patented rectangular-bin shelf system, the TX750 offers 30 percent more storage capacity than its predecessors and allows each storage bin to be customized from 2" to 60" in ½" increments (50.8mm to 1,524mm in 12.7mm increments) to fit the item being dispensed, virtually eliminating vertical bin "height" waste associated with fixed-door machines. The computer can also be connected to the company's new AutoLocker FX, a modular locker system with "smart" charging capabilities and management control for a company's tools and technology assets.
Dual-stage coolant reduces resource use
Quaker Chemical's new two-phase 2PAQ fluid system can be used as both a cleaner and to top off sump tanks. The emulsion is formulated in different solution ratios of the alkaline and oil phases, mixed with water, depending on the nature of the operation; operations requiring higher levels of lubrication use the oil phase at a higher ratio, while cleaning operations use a higher ratio of the alkaline phase. When the cleaner becomes saturated, it is added to the coolant tank to aid with volume control. According to Product Manager Laurent Ilievski, the system can reduce waste generation by up to 90 percent. Water consumption is minimized, capital investments in wastewater treatment equipment are reduced or eliminated, and energy and wastewater treatment costs are reduced because significantly lower quantities need to be treated.
Modular conveyors reduce cost of automation
Wes-Tech Automation Services' Tech-Trak conveyors are single-strand, power-and-free palletized conveyers available in a variety of preset modules. This modularity allows for the design of any configuration required to accommodate any process while making efficient use of space requirements, according to the company. If multirail conveyers are necessary, other brands' conveyors can be accommodated and integrated into the system design. Each module uses a single part number for ease of ordering, and the modular nature of the system reduces cost and delivery time.
