Jena-Tec, part of the Avingtrans Technology Group, has launched the Duplex tool post grinding range to the UK and European markets. The product range has been strengthened and improved using Jena-Tec's precision rotating equipment knowledge to provide improved serviceability and durability ensuring that we continue to provide a quality machine tool attachment.

Mounting directly to or replacing the tool post units of most centre lathes or vertical boring machines, ranges start from the D26 providing 60mm diameter external wheel and 20mm internal wheel through to the D35 providing 500mm diameter external wheel diameter.

This range is also complimented by the high frequency direct drive 12,000 rev/min D68 and D69 units used for intermittent internal grinding of hardened components that replaces a standard turning tool in the tool post.

The standard modular cartridge spindle design allows replacement of a variety of different options for example for grinding deep bores that would be otherwise un-accessible with a turning tool due to deflection of the tool.

Jena-Tec can provide spindles with 610mm depths for internal bores.

While this provides a range of precision grinding options, Jena-Tec also have introduced abrasive band tool post grinders that allow fixed or adjustable angles using low cost abrasive bands for roll finishing, de-burring and polishing of large cylindrical components again on standard centre lathes.

Units are designed to accept band widths 25mm to 100mm.

The Duplex range have distinct advantages as a machine attachment to allow customers to grind cost-effectively on standard centre lathes and vertical boring machines.

Increasingly, Jena-Tec is seeing non-machine tool applications such as robotics and special purpose machines.

Applications are as diverse as precision tool room grinding through to grinding of blade tips on gas turbine rotors.

This concept which is unrivalled by their competitors in terms of product variety and scope offers a low investment method of attaining grinding capability without investment in a dedicated grinding machine.

Prices start at below GBP 800 for the base Duplex model providing both internal and external grinding capability.
