EMO 2021 Sharpening specialist to launch world premiers at EMO Milano

Editor: Alexander Stark

From 4th to 9th October, Biberach-based Vollmer will be be presenting its sharpening machines and digital solutions for efficient and networked machining of cutting tools. One of the highlights on show will be the new VHybrid 260 grinding and erosion machine as well as the VLaser 370 laser machine. There will also be a world premiere in the form of a new tool grinding machine.

When EMO 2021 open its doors, visitors to stand E18/F13 in Hall 2 will be able to gain insights into the latest Vollmer portfolio of sharpening machines and services. This will include all the latest information on its wide range of grinding, erosion and laser machines for machining milling cutters, drill bits, reamers, circular saws and band saws. The full-line supplier offers various sharpening solution for sharpening tools tipped with carbide or PCD – also incorporating automation for unmanned production around the clock.

The newest model of Vollmer grinding machines is the VGrind 360S. According to the company, this new machine can be used productively to machine carbide tools with a diameter up to 25.4 mm and depending on the machine kinematics and the tipping of the grinding wheel packages, it can even be used for tools up to 150 mm diameter. Incorporating wear-free linear induction motors on all three axes lower maintenance costs for the machine whilst demonstrating higher surface quality for the tool.

The double-spindle concept features an oriented spindle stop for the first time. This always stops the spindle at a specific position. This function is also known as spindle indexing. This reduces axial run-out errors and concentricity errors further and offsets wear in the HSK holding system. Another new feature is a heat plate exchanger to efficiently cool motors and spindles, which in turn leads to increased thermal stability. The VGrind 360S incorporates Vollmer's operating concept and can be operated unmanned around the clock thanks to automation features such as pallet magazine, free-arm robot and chain magazine.

Premiere of the VLaser 370

Restrictions permitting, the Vollmer VLaser 370 machine will have its live exhibition premiere in Milan. The VLaser 370 uses the power of a non-contact laser to sharpen the cutting edges of cutting tools made of PCD or other ultra-hard materials. At the core of the machine is its fixed laser beam guidance with precision machine kinematics. How the five axes are arranged means that the tool is always machined at the pivot point of the C-axis. This makes it possible to sharpen tools with minimal axis movement to ensure stable process control.

Precision grinding and eroding

Also on show at EMO will be the VHybrid 260 grinding and erosion machine. This machine is to enable tool manufacturers to grind and erode a wide range of carbide and PCD tools in one combined set-up. The machine combines technologies and experience that the company has gained in the fields of grinding and eroding over many decades. The key component for the eroding process is the VPulse EDM erosion generator, which optimises efficiency and surface quality, the company states. For grinding operations, the VHybrid 260 features the machine concept of the VGrind series.

Comprehensive service package

The trade fair will also be attended by the Vollmer Service division. The team will present offers for maintenance, servicing, training, financing and digitalisation. This will include digital solutions from the manufacturer's V@dison initiative, such as the “Performance Pack for VHybrid 260” V@ boost solution or the “Visual Support” V@ guide solution that enables customers to connect with Vollmer technicians in real-time.
