VGrind 340S ROTARY TOOLS Grinding machine for the complete machining of carbide tools upwards of 0.3 mm in diameter

7//// ROTARY TOOLS CARBIDE MACHINING /////////////////////^ THE GREATEST PRECISION FOR EVEN THE SMALLEST OF TOOLS. VERTICAL MULTI-LEVEL MACHINING THAT SETS NEW STANDARDS. THE PRECISION AND EFFICIENCY OF THE VGrind SERIES IS NOW ALSO AVAILABLE FOR ROTATIONALLY SYMMETRIC SOLID CARBIDE TOOLS IN THE 0.3 MM TO 12.7 MM RANGE. THE VGrind 340S: A FIVE-AXIS GRINDING MACHINE THAT IS EQUIPPED WITH ALL THE ATTRIBUTES THAT MODERN TOOL MANUFACTURING REQUIRES. AND, WHAT'S MORE, THERE ARE PLENTY OF INTUITIVE DETAILS FOR THE PRODUCTION OF SMALL SIZES TO BOOT. NEW LINEAR INDUCTION MOTORS ON THE X, Y AND Z...

VGrind 340S – SUPERIOR IN EVERY WAY 1 WALL CONCEPT Very rigid, compact construction with optimal accessibility and overview for the operator. 4 NUMROTOplus® The reliable, intuitively operated software with 3D tool and machine simulation, combined with collision monitoring. 2 MULTI-LAYER MACHINING Two vertically configured grinding spindles with the grinding wheel set at the C axis pivot point. Reduced machining times thanks to shorter linearaxis travel distances. 5 GRINDING-WHEEL CHANGER Provides even more flexibility in your manufacturing processes – with eight HSK-50 grinding wheel sets....

/// THE MACHINE CONCEPT Precision and efficiency squared: The VGrind 340S benefits from two vertically arranged grinding spindles. This principle is complemented by several useful details and options for machining small radii. The result: Maximum perfection at the lowest tolerances. /// Five-axis CNC grinding machine with innovative kinematics /// Two grinding spindles situated one above the other with the grinding wheel set positioned at the C axis pivot point – for ensuring extremely precise grinding results /// The vertical spindle arrangement solves the well-known problems related to...

/// New wear-free linear induction motors on the X, Y and Z axes not only guarantee lasting consistency of quality and lower maintenance costs, but are also the key to improved surface quality /// Innovative wall concept with the highest possible rigidity and outstanding damping thanks to polymer concrete /// Effective motor and spindle cooling concept for higher thermal stability and lasting power and precision /// Both spindles can be fitted with various different grinding wheel sets. The automation option ensures seamless conversion /// Equipped with a tool steady rest as standard for...

/...// THE MACHINE CONCEPT OPTIONAL EQUIPMENT /// Flexible automation options for loading of carbide tools /// Grinding spindle available with a motor or belt drive /// Automatic gripper compensation as an in-process solution: Maximum precision when loading and unloading tools and reduction sleeves for decreased wear and optimal radial run-out /// Automatic changing of grinding wheel sets complete with coolant nozzles for optimum productivity //// COOLANT NOZZLES for optimum coolant supply 06 //// GRIPPER COMPENSATION Safe, precise loading and unloading

/// Internal grinding wheel dressing device: For consistently optimal radial and axial run-out /// Automatic sticking unit enables the abrasive coating to be opened during production /// Wheel probe: Grinding wheel alignment and wear control within the machine /// Automated changing of intermediate sleeves with bayonet //// INTERNAL DRESSING DEVICE New efficiency: Fine dressing of the grinding wheel as an internal process //// STICKING UNIT for opening the abrasive coating 07

/// THE APPLICATION The VGrind 340S was designed to produce carbide drills and milling cutters with a diameter ranging from 0.3 to 12.7 mm. The high flexibility provided by the possibility to change both grinding wheel packages, the reduced changing times thanks to the positively guided system and the meaningful automation options provide the best prerequisites for efficient and high-quality manufacturing. //// MACHINING CARBIDE MILLING CUTTERS //// MACHINING CARBIDE DRILLS

//// MAXIMUM PRECISION at the smallest scale: From 0.3 mm 09

/// THE OPERATING CONCEPT In order to be able to exploit the full potential of your VGrind 340S, simple and intuitive operation is a fundamental prerequisite. This begins with the control panel, which is positioned so that not only the LCD display, but also the working area can always be observed in the best possible manner. Operation via the keyboard or touchscreen allows for precise machining of the tool. The multifunction handwheel ensures even more flexibility: It can be freely positioned on the enclosure and is designed for setting a required axis – without using the control desk. In...

/// SOFTWARE NUMROTOplus ® VOLLMER consciously opted for a sophisticated system that is already established on the market. The logically structured interface guarantees intuitive handling. With established programming systems, a large variety of tools can be manufactured and resharpened. As a result, every detail on individual tools can be altered and adapted to individual needs. Fully informed: Thanks to a perfect 3D diagram of the tool and machine. And with collision monitoring, you can always stay on the safe side. /// Develop /// Simulate /// Monitor /// Produce /// Measure ///...

/// THE AUTOMATION One of the key factors in modern tool production is automating the work processes. The VGrind 340S therefore features a range of useful configuration options that allow you to implement large batches of small tools and make your manufacturing processes more precise, quicker and safer. //// TOOL AUTOMATION An extremely wide variety of automation solutions can be attached 12

/// TOOL AUTOMATION With the various automation options that are available, the VGrind 340S can be optimally adjusted to your requirements. /// PR250 free-arm robot: Allows for the automatic machining H of tools with various shaft diameters /// P 160 pallet magazine with compact pallets (for up to H 900 slots) and double gripper to guarantee a quick change between short machining times //// HP 160 PALLET MAGAZINE for the quick supply of up to 900 workpieces //// HPR250 FREE-ARM ROBOT for increased capacity and even greater flexibility 13
