Okuma launches two-spindle smart CNC lathe 2SP-2500H

Okuma adds the 2SP-2500H CNC lathe to its line of a smart machines. The innovative front-facing twin spindles provide significantly higher levels of productivity and far greater reliability in mass production, especially for automotive parts. The compact automation-ready machine provides excellent floor space utilisation and integrates two lathes into one unit with a standard loader for continuous front and back work.

The latest entry in Okuma’s 2SP-H Series of two-spindle CNC lathes is designed to provide consistent quality in mass production while increasing efficiency through process-intensive machining and automation. The lathe enables stable unattended production over long runs via a high-speed loader feeding blanks. Due to the machine’s unique design, the loader is able to enter the 2SP-2500H regardless of the turret’s position. Since turret retraction is not necessary, workpiece transport and changeover times are greatly reduced.

With 5,000min-1, the lathe’s turning spindle offers the fastest spindle speed of its class. The 2SP-2500H offers unrivalled floor space utilisation with the smallest-in-class machine width of 2,200 mm. Despite its compact dimensions, the machine features an impressive maximum turning diameter of 250 mm.

The 2SP-2500H is 20% faster than previous models. With a maximum spindle speed of 6,000min-1 and a doubled max motor output of 7.1 kW, the machine’s milling capabilities are on par with that of a small machining centre. Other applications include powerful face milling, drilling and tapping.

Okuma’s Intelligent Technology application Thermo-Friendly Concept minimises thermal deformation and enables supreme accuracy. A tool life calculator predicts the remaining time before an exchange is required and prevents cutting edge breakage, thus reducing costs.

Stirring the imagination of electric car OEMs

As sales of hybrid and all-electric cars continue to gain momentum, UK-based PTG Heavy Industries is busy applying its considerable knowledge of friction stir welding to help automotive OEMs address some of the challenges associated with the manufacture of electric-powered vehicles.

Powerstir friction stir welding, from PTG Heavy Industries.

“Longer battery life and reduced vehicle weight through the greater use of plastics and aluminium panels, are well known objectives for electric car makers,” comments PTG Heavy Industries’ Applications Manager, Peter Jowett. “However, the development of electric cars has brought other less-well-known challenges for vehicle manufacturers,” he continues. “For example, how do they fabricate lightweight, robust and aesthetically sealed battery housings efficiently – particularly when the heat generated by traditional welding techniques could so easily damage the highly sensitive electrical components that the housings contain? With our considerable expertise in friction stir welding, we are providing automotive OEMs with highly viable manufacturing solutions for battery housings, solutions which involve no surface finishing and remove the risk of heat damage to delicate components.”

Working with magnesium alloys

As manufacturers of the world-acclaimed Powerstir range of friction stir welders, PTG Heavy Industries is an acknowledged leader in this innovative means of jointing metals. Working with magnesium alloys of 3mm – 5mm in thickness, and to tolerances of typically 50 microns, the company is currently assisting automotive OEMs in the production of vehicle battery trays, associated electronics boxes and coolant units, by using its 2D friction stir welding techniques.

Using industry standard CNC systems, fitted with PTG Powerstir friction stir welding software, data-logging and multi-axis interpolation, 2D welding can be carried out on accurate tool paths, together with force control to create consistent welded seams.

Superior high-strength joints

“Our work to-date, involving the production of automotive battery enclosures using friction stir welding techniques, is exciting and is providing novel opportunities for vehicle design engineers to achieve both light weight and structural rigidity in electronics units that benefit from superior high-strength welded joints,” adds Peter Jowett.

Proven weld quality

Since their launch, Powerstir machines have attracted considerable interest from organisations seeking an innovative way of creating superior high-strength welded joints. Used primarily for jointing aluminium, magnesium, copper, titanium, steel, lead and zinc, the Powerstir friction stir welding process provides a clean, highly aesthetic alternative to traditional welding. It delivers proven weld quality, excellent mechanical properties, virtually no porosity and the opportunity for reduced wall thickness in many applications.

About Powerstir friction stir welding

Patented by TWI (The Welding Institute), friction stir welding is a unique and innovative means of jointing metals. The process combines frictional heat with precisely controlled forging pressure to produce extremely high-strength joints that are virtually defect free. Friction stir welding transforms the parent metal from a solid to a plasticised state. This occurs during a process that involves mechanically stirring the materials together to form a high-integrity, full-penetration welded joint.

Powerstir applications include:

  • Heat sinks and electronics enclosures
  • Locomotive train and carriage panels (aluminium)
  • Aircraft fuselage and avionics development
  • Truck bodies, caravans and space frames
  • Boat and ship panel sections
  • Flat and cylindrical fuel tanks and bulk liquid containers
  • Aluminium bridge sections, architectural structures and frames
  • Pipelines and heat exchangers
  • Electrical motor housings

Predictive Maintenance: Sensor system for driven tools

With the new sensor system Heimatec.Cybercon 4, different tool parameters can be measured and forwarded to a monitoring station. The collected data can be used for maintenance purposes and to prevent machine failures.

Digital tool management becomes a reality with Heimatec.Cybercon 4.

The sensor system, which has been integrated into the driven Heimatec tool, can be used to measure various tool parameters such as operating time, rpm, temperature or humidity. As the company explains, the collected data are transmitted wirelessly to the monitoring station after a defined time cycle via Bluetooth Low Energy technology and can then be used for evaluation and maintenance activities.

In addition, by means of a moisture sensor (“Tsunami alarm”), the entry of liquids such as cooling lubricants into the tool or the machine is immediately reported to the control center so that major damage or machine failures (idle time) can be prevented. By using the monitoring software, tools equipped with the solution can be supervised to help manage maintenance cycles. For example, checks can be made as part of an intelligent tool management as to when the next service application is required and what measures need to be taken.

Wibu-Systems will be showing at the trade fair EMO 2017 how connected systems for intelligent production can result in new revenue streams. The digital business platform from Axoom, for instance, is designed for use along the entire production value chain.

Codemeter from Wibu-Systems protects the intellectual property and also provides business-enabling opportunities through versatile and secure software licensing, which are demonstrated in this case with a drinks tapping machine. As the company explains, the producer creates a new drink, whose recipe is encrypted via Codemeter and transferred to the Axoom marketplace. The corresponding license is set as an item in Codemeter License Central, the database-derived license and entitlement application, which automates the process of creating, delivering, and managing software licenses. The consumer, for his part, selects a drink of his or her choice. The order travels through the marketplace, and the license for the creation of this specific drink is then transferred from Codemeter License Central to the mixer.

Abrasive machine tools: High stock removal capacity thanks to new hybrid bond

Cafro, a manufacturer of diamond and CBN wheels and tools, will be presenting the new M404 hybrid bond at EMO Hannover 2017.

The new M404 hybrid bond is now part of the Cafro 2017 stock list.

The company, which has recently joined the Mirka Group, reports that in its manufacture of carbide mills and drills, the main requirement is working time reduction. This is said to particularly apply during the fluting operation. Tests on CNC grinders have apparently shown that the new M404 hybrid bond allows for higher stock removal with lower power absorption, a longer dressing interval and a better surface finish than the market benchmarks.

According to the Italian exhibitors, the wheel is silent during grinding, there are no vibrations, both the wheel and workpiece remain cold, power absorption at the spindle remains constant, and there are no absorption peaks. The new hybrid bond is now part of the Cafro 2017 stock list, which has been expanded and improved thanks to new technical developments. These include the new Standard Line CBN products (quality WD) and the new bond family Top, which is described as a resin bond with the best profile retention.
