The recent MACH 2018 exhibition once again proved to be a huge success for Vollmer UK, with the tool and saw-blade grinding and sharpening specialist winning an order at the show as well as generating a high number of enquiries. Vollmer had three machines on its stand.

Making its debut at MACH 2018, the Loroch K850-M for processing metal-cutting saw blades got proceedings off to a flier with Birmingham-based Precise Saw & Tool Ltd placing an order at the show. Purchased to add capacity to its existing operation, the Loroch K850-M has a 50-blade capacity and robotic load/unload for extended unmanned running.
The centrepiece of the Vollmer stand was the new Vgrind 360 tool grinding machine that also made its UK exhibition premiere. Vollmer‘s next-generation Vgrind 360 is the successor to the Vgrind 160 model, now equipped with enhanced travel distances for accommodating carbide drills and milling cutters whose blanks are made from either solid-carbide or carbide-tipped steel bodies up to 200 mm diameter.
Vollmer UK technical sales engineer Kieran Rosling says: “Enquiries for the Loroch K850-M and the CHC840 saw-blade sharpening machine were particularly high. We conducted a number of demonstrations on both machines during MACH week and have a number of further trials with various manufacturers showing serious levels of interest. However, the Vgrind 360 tool grinding machine was certainly the show-stopper for us. The innovation of the Vgrind 360 was evident and the enquiry level and number of follow-on meetings we have booked is really encouraging.“
Featuring two grinding spindles, the Vgrind 360 can be loaded with different tools, while an optional tool magazine with eight grinding wheel packages allows tools on the vertical spindles to be changed automatically.

Techni-Grind (Preston), a supplier of tool regrinding services to the aerospace industry, has installed its sixth Walter CNC tool and cutter grinder to increase capacity levels – a Helitronic Vision 400L with integrated robot handling and wheel changer.

The new machine not only extends the length of tooling that can be processed – to 420 mm long – but its automated handling and wheel changing capability will also, says Techni-Grind’s manager Michael Bell, “further extend our ability to confidently run the Vision 400L unmanned and in a lights-out mode, thus further increasing our productivity levels”.
Capable of processing tools up to 315 mm diameter and 420 mm long, and weighing up to 50 kg, the Vision 400L has travels in X, Y and Z of 500, 350 and 700 mm, respectively. Rapid traverse rates are up to 50 m/min, and the machine boasts linear and radial resolutions of 0.0001 mm and 0.0001°. Grinding wheels up to 254 mm diameter can be accommodated within the eight-station wheel changer, and grinding spindle speed is up to 10,500 rpm.
The Vision 400L joins the company’s existing portfolio of Walter tool grinders and tool measuring machines, which have been progressively installed – a Classic Power, a Power, a Power Regrinder and two Helitronic Visions (one with robot loading), plus a Helicheck Basic tool measuring machine.
Now, with the new machine meaning that two of the company’s Visions are equipped with robot loader and pallet-held tools, these automation devices “are key to our often non-stop 24-hour running which, of
course, contributes greatly to
the production efficiencies we attain”, says managing director David Higham.

To complete its coated abrasive product line, Master Abrasives has introduced its own range of cartridge rolls under the MASTER brand.

Master cartridge rolls are available in aluminium-oxide and ceramic-oxide abrasive. Rolls are offered with either a straight or tapered side allowing access to angles and corners. The aluminium-oxide variety is now being stocked in a range of grits and sizes at Master Abrasives.
Andy Wright, national sales manager, says: “The nature of a cartridge roll makes it a long-lasting and excellent solution for deburring and metal removal applications. Each product is a length of abrasive cloth wound around a spindle for a multi-layer effect, exposing new abrasive cutting points throughout its operational life.
“The key advantage of cartridge rolls is their unique shape, which makes them ideal for application on contours and hard-to-reach areas on all ferrous materials,” he continues. “They can be used for numerous applications, including deburring, flash removal, edge breaking and removing machining marks.”
