No less than eight of Advanced Grinding Solutions’ principals are exhibiting at the forthcoming GrindingHub exhibition including Rollomatic in Hall 7 on Stand C70, Tschudin and HandlingTech in Hall 9 on Stand D5, Bahmuller in Hall 10 on Stand D70, Krebs & Riedel in Hall 10, Stand E30, Comat in Hall 10 on Stand B44, Platit in Hall 10 on Stand B30, and FLP in Hall 10, Stand D07.
Rollomatic will be using the event to showcase its latest range of CNC tool grinding machines, blank prep cylindrical grinding machines and laser machines for PCD tooling.
One machine which will be the centre of attention will be Rollomatic’s new GrindSmart 660XW grinding machine which combines, for the first time, the power and performance of a blank prep cylindrical grinder with the flexibility of a multi-axis tool grinder to allow for all machining operations to be carried out in one single automatic operation on the same machine and in one clamping.
Therefore, cutting tools may be machined complete in a highly efficient single grinding process. Typical production efficiency from the traditional multi machine production method for standard end mills is in the region of 11% and this is said to increase to around 82% on the Rollomatic.
The new LaserSmart Femto 510 machine from Rollomatic offers cutting speeds of up to 500% faster than conventional laser machining, the company claims. The laser machining process is ideal for machining super-hard materials such as PCD and CVD diamond and creates razor-sharp cutting edges with a radius of under 1μm.
Rollomatic’s ShapeSmart machines are designed for grinding tool blanks and are based on the company’s peel grinding technology. This new generation of cylindrical grinding machine has been improved to offer more advantages for fast setups and excellent grinding quality including both rough and finish grinding in a single automatic operation for tools up to 25mm in diameter.
The 4-axis NP30 machine is a precision pinch and peel grinding machine for producing cutting tool blanks such as end mills, drills and stepped tools and also steps, tapers and radii. For special tools and punches, Rollomatic’s 5-axis ShapeSmart NP50 machine uses a patented method of peel grinding which allows the grinding of non-round shapes such as ellipses, squares, triangles or hexagons. The machines benefit from Rollomatic’s three-year unlimited hours, parts and labour warranty and free-of-charge software updates for life.
For the first time, Tschudin will exhibit three machine types at the event. “Workpieces of the most diverse sizes can be ground on our machines – from the smallest wires for medical technology that can only be seen under a magnifying glass, to truck axles weighing 150kg," reports Iwan von Rotz, CEO of Tschudin AG.
Tschudin’s product portfolio comprises three different machine types. The compact, centreless Cube 350 is the latest innovation: "We developed this patented 3-axis CNC grinding machine specifically for machining small workpieces up to 20 m in diameter,” Mr von Rotz adds. “The machine has a small footprint and offers maximum efficiency – a real all-rounder."
The other two machine types are the 400 ecoLine/proLine which is ideal for machining medium-sized workpieces with a diameter of up to 150mm, and the centreless grinding machines that make up the 600 ecoLine/proLine, which can also machine larger workpieces with a diameter of up to 250mm and a length of up to 500mm.
Centreless cylindrical grinding machines from Tschudin are used in all industries where mechanical components are required with high precision and at economical unit costs – from injection technology, hydraulics and automotive engineering through to drive technology, the bearing industry, medical technology, toolmaking and aerospace.
Bahmuller produces high precision internal, external and combined universal grinding machines used in applications such as the grinding of diesel injection units, hydraulics, turbo chargers, valve trains and other highly precise mass produced components.
For pinion gears the company has developed a solution with its Qube machine to grind both faces, and to also grind and hone the bore in the same production cell. For bore grinding Bahmuller offers a variety of solutions with grinding spindle speeds of up to 250,000rpm for grinding bores as small as 0.8mm in diameter. Bores are ground to the highest precision with roundness and straightness of 0.1um and surface finishes of 0.3um Rz.
Krebs & Riedel is a leading German grinding wheel manufacturer with over 250 employees and distributors in 32 countries. The product range includes conventional internal and external grinding wheels up to 900mm in diameter manufactured using aluminium oxide and silicon carbide with ceramic and synthetic resin bonds for most industrial grinding applications.
Krebs & Riedel vitrified diamond and CBN grinding wheels with ceramic bonds have a working speed of up to 200m/s for internal, external and special grinding processes and new types of wheels with improved grain structures and novel bonding systems that optimise performance are being created. The business has one of the largest ranges of grinding wheels available for a wide variety of applications.
Comat manufactures super-filtration systems that deliver ≤ 2-3μm filtration quality (making oil cleaner than unused oil as supplied new) and importantly do so throughout the entire working cycle whilst minimising lifetime running costs and maintaining maximum coolant consistency.
Importantly for end users, the Comat filter systems use their Intelligent Performance Technology that allows them to be remotely monitored in real-time during the manufacturing processes with customers’ filter systems fine-tuned by Comat to ensure that the optimum filtration quality is obtained at all times.
Furthermore depending on the model, Comat filter units can be monitored, controlled, and optimised by integrated controls or externally by PCs, tablets or smartphones. Today, more than 20,000 machine tools use Comat Filtration Systems, with more than 120 million litres of metalworking oil being super-filtered every day. Comat operates globally and has a 30-year history in developing advanced filtration systems.
Comat's Superfiltration technology uses continuously regenerating filtering media (diatomaceous earth, cellulose or other vegetable media), to ensure that particles larger than ≤2-3μm are removed from cutting fluids and the fluid is maintained at a stable desired fixed temperature of ±0.2°. Oil cleanliness is measured according to international standards such as the National Aerospace Standard 1638.
Brand new, neat cutting oil is typically classified in category 9. However with Comat Superfiltration systems brand new clean oil is brought down, and then held, to a finer filtration category of just 7 or 8.
Platit is a global manufacturer of coating machines using plasma generating PVD technology. One of the main applications for Platit equipment is the coating of cutting tools (usually TiN, TiCN, CrTi). sputtered monoblock coatings, TiXCo nanocomposite coatings, BorAC-Arc boron doped AlCrN coatings and SCiL coatings (sputtered coating induced by LGD) and CCS (custom coating solutions) are all available.
Platit’s open-source philosophy allows customers to adapt coatings to their specific requirements and individual needs. It offers turnkey solutions including de-coating, edge pre-treatment, cleaning, post-treatment and quality control, making Platit systems ideally suited to seamless integration into the tool manufacturing and regrinding process allowing cutting tool manufacturers to easily and cost efficiently coat their own tools instead of relying upon expensive and time consuming subcontract solutions.
FLP Microfinishing claims to be the only company in Germany to offer the entire range of industrial fine grinding, lapping and polishing machines for flat surface finishing from a single source.
The four FLP product lines are new single and double sided machines (both standard and full CNC), fully rebuilt and refurbished machines, the supply of lapping consumables and tooling, and finally a large subcontract lapping facility.
The broad range of FLP fine grinding and lapping machines includes both twin wheel, double-sided CNC version as well as single wheel machines. Around 25% of FLP’s sales are for fine grinding machines that are said to offer two to three times the stock removal of more traditional lapping machines.
75% of sales are for lapping machines that are used where there is a low stock removal requirement with a mirror finish and perfect flatness. The fine grinding process, that uses diamond or CBN wheels, is much cleaner than lapping and virtually eliminates workpiece cleanliness issues. Furthermore, this process is many times faster than lapping and bridges the gap between traditional lapping and standard grinding technologies.
