Grinding

VGrind 260, VGrind Neon and VGrind Argon – these are the names of the three new tool grinding machines from the sharpening specialist VOLLMER. They were presented for the first time at the GrindingHub 2022 trade fair in Stuttgart.

The S36 has a fixed grinding head, with grinding wheel angles of 0, 15 or 30 degrees available. The distance between centers is 650mm and the maximum workpiece weight is 150kg. Proven components have been used in the machine. These include a Granitan® machine bed and a workhead with high-precision roller bearings.

The new duo of VOLLMER grinding machines designed for machining carbide-tipped circular saw blades, is made up of the CS 860 and CSF 860.

As an external loader, STUDER roboLoad measures only 59.06" (1.50 m) wide: half the width of the machine itself. This saves valuable shop floor space, and yet the system offers plenty of room for workpieces manually loaded on six trays – each measuring 42.52" x 12.6” (1080 mm x 320 mm) – within a comparatively small work area. 

The thermal stability is exceptionally high due to an innovative machine design and a rigid 5‐axis configuration. Field tests have demonstrated an unusually high Cpk process capability. This is of particular importance when grinding short‐run custom tooling where accuracy and “first‐tool‐good” are critical. 

The NXT grinder is a versatile 5-axis CNC machine with a small footprint, large grind zone and a modular design that quickly adapts to demanding application requirements. ESPRIT uses a digital twin of the manufacturing envelope to simplify the programming process and deliver edit-free G-code. Customers that already have ESPRIT can add the Star Cutter NXT’s digital machine package to their existing license and program the NXT using the software they already own.

The GrindSmart 660XW is a 6-axis tool and peel grinding machine allows the user to utilize cost-effective and advanced  lean manufacturing principles; termed as “Ultra-Lean Grinding Process.” The machine includes a 6•position wheel changer and linear motors on all axes. It features a traveling high-speed workhead. Peel grinding for blank prepara•on and neck grinding are included in the same chucking.

The longest-lasting, fastest-cutting abrasive is especially effective for hard-to-grind applications like stainless steel weldments, nickel alloys and ferrous metals.

The abrasive grain used in the Blue Moon TZ is very sharp-edged, microcrystalline and has an elongated trapezoidal rod shape. Blue Moon TZ grinding wheels are particularly impressive due to their very low thermal load in the contact zone. The high profile retention of our grit combination leads to extended dressing intervals at high stock removal rates and increases economic efficiency.

The wheels feature an innovative Norton Quantum Prime nano-crystalline ceramic grain, embedded in an optimized matrix of Norton Vitrium3 bond. The combination of the micro-fracture properties of the new ceramic grain from Saint-Gobain Abrasives and the retention capability of the bond ensures long wheel life, excellent grinding efficiency, and consistent part quality with superior finish which results in cost savings of 30% and more.

Norton Quantum Prime Wheels have several important advantages including a new micro-fracturing grain that has unparalleled sharpness and cutting efficiency which reduces power draw and cycle times, while increasing material removal rates. The unique grain is free cutting, which combined with advanced bond technologies such as Norton Vitrium3, allows Quantum Prime to wear more consistently, improving part quality, geometry and finish even at high material removal rates.

Glebar pairs the wider work wheel with an oscillating regulating wheel powered by servo motors to reduce setup time and improve sphericity. The slides can be programmed to finite positions through a touchscreen HMI. When an operator selects a job, the servo motors automatically adjust to programmed positions which reduces setup time.

The Type 11 cup wheels for grinders are precision balanced to ensure smooth, vibration-free operation and reduce operator fatigue, while wearing at the appropriate level to maximize grind rates. Designed for ID cleaning, hole-edge beveling, smoothing weld seams, bevel grinding, transitioning and grinding in hard-to-reach areas, the Tiger AO cones and plugs for die grinders feature an open-face design that provides an aggressive cut rate right out of the box.

This model is part of the GrindSmart® series of tool & cutter grinding machines with an axis configuration that incorporate 6 fully interpolated axes (3 rotary and 3 linear) and is unique in this industry. The machine also incorporates linear axis drive technology. 

In addition to speed, the new robots handle an increased number of workpieces/tools, are more compact and consume less energy. They also support the latest WALTER HELITRONIC Tool Studio and Robot Manager software that allows users to load multiple trays with various workpiece diameters for lights out unattended production.

Both grinding spindles are “synchronous direct‐drive spindles” with 19 hp peak each. The most important feature of a synchro­nous motor is that it provides constant speed during its operation and that the torque curve is highly efficient, as per above graph. The rotational force is not reduced with higher RPM’s. Synchronous motors always run at a speed equal to their syn­chronous speed, as opposed to asynchronous motors (induction motors) which always have a lag and are therefore less effi­cient. 

The updated automation package accommodates denser pallet arrays for improved lot sizes and runtime, while delivering smoother robot operation and better repeatability. Additionally, the system can now adapt to multiple part profiles to be produced within a single run. An optional laser marking system has also been integrated for automated tool marking, in addition to many other new features.

V-PRIME grinding wheels significantly increase productivity and reduce cycle times due to requiring lower grinding forces and permitting higher feed rates. User-friendly off-line dressing optimizes grinding wheel preparation, saving time and cost. The new wheels also offer an excellent price/ performance ratio.

Dental tool grinding on the 5-axis GrindSmart Nano5 grinding machine offers exceptional flexibility in comparison to conventional single-purpose grinders. With its 5 fully interpo­lating CNC axes and a pick-and-place automatic tool loader, the machine can easily be adapted for any type of dental cutting instrument, both for short and long runs. 

Premium Ceramic Grain - provides a cooler cut for a longer lasting disc; 50 Grit – less emphasis on aggression with refined surface finish; 36 Grit – best combination of stock. Works well on stainless steel & carbon steel, weld bead removal, chamfering and beveling, flame-cut steel removal, edge grinding and deburring.

Every grinder provides four to seven times longer duty cycle under load and eight times less speed degradation than the  competition. The grinders provide smooth, quiet power for grinding cleaning, deburring, chamfering and sharpening.

Because aluminum has a much lower melting temperature than other metals, keeping aluminum cool while grinding and finishing is a big challenge for welders and fabricators. The Blue-Kote disc cloth’s net structure resists clogging on soft materials, and its sanded surface stays cooler and avoids burning the work surface.

With a smaller diameter, quick change discs provide ease of use on intricate parts and excellent control when shaping or blending surface portions, especially on flat surfaces.  Moderate flexibility of quick change discs and their holders allows contouring and access to inner corners.  These unique quick change functionality reduces changeover downtime and eases transitions between grit, material, or even abrasive type where multi-step processes are required.

The Minimicromar3 is designed for measuring external diameters, positioning and length for both smooth and interrupted surfaces.  It can measure workpieces from 25mm to 42.5mm with a measuring range of ±100 µm and a repeatability of ≤0.1 µm.  It is designed with a high degree of protection against coolant and abrasive substances.  Its low thermal drift value (<0.1 µm/°C) helps maintain high measurement precision.

The machine’s capabilities include a 15 kW direct-drive motor that produces maximum wheel spindle speed of 6000 m/min. X-axis stroke of 330mm features a rapid feed rate of 5m/min, Z-axis stroke is 2150mm with 10m/min rapid feed, and maximum work spindle speed is 200 rpm.

Pinch grinding offers highest concentricity particularly on long and thin parts. The rough and finish grinding are performed in one pass. This innovative way to grind roughing and finishing simultaneously eliminates a separate process and reduces cycle time. The machine utilizes two different grinding wheels running on separate spindles and positioned on independently- controlled CNC linear slides.

Pinch grinding offers accurate geometrical dimensions on the blank and tight surface finish requirements. In pinch grinding, the roughing and finishing wheels grind parts simultaneously, with the finishing wheel trailing the roughing wheel. The rough and finish grinding are performed in one pass. This innovative way to cylindrically grind parts eliminates separate processes and reduces cycle time. 

With five axes of motion and storage for 40 tools, the machine can grind thread grooves and also machine the nut circumference, end surface, key grooves, and return tube holes in a single setup. In addition to producing large savings in manufacturing time, elimination of setup changeovers also assures exact phase alignment of thread grooves and return tube holes. A standard touch probe enables automatic pre-processing phase alignment of the thread groove and wheel.

Norton Winter AEON Grinding Wheels have a single usable abrasive layer design, with diamond or cBN particles mechanically fixed onto the core surface by an electrochemical process of nickel deposition. This unique layer design provides high grit retention levels for long wheel life. To save costs, the wheel core can be re-used. Once the abrasive grains are worn, the core of the wheel can be re-plated with new diamond or cBN grain in a continuous re-plating cycle.

The Tiger large diameter wheels for performance cutting and the Wolverine wheels for standard cutting include specialty products. Among those are the Tiger AO wheels for stud cutting, as well as Tiger AO and Wolverine AO wheels with single center reinforcement for increased speeds and burr-free cutting — both designed for use on chop saws.
