Machining of many new and emerging materials, more specifically but not limited to composites, plastics, and foams, often results in the creation of fine waste products and dusts.

These by-products of the machining process serve no useful process, and are commonly detrimental to the machining process and life of the machining centre. Most notably, abrasive dusts can result in rapid wear of ball-screw, spindle, and guideway components which are usually costly to rectify. In addition to machine damage, inhalation of such materials can pose significant health risks if left to collect in the air.

  • Cost-Effective & Retrofittable Solution

    dust & particle removal for new & existing machining centre

  • Promotes smooth cutting operations

    removing waste from the cutting zone

  • Suitable for both wet & dry cutting applications

  • Addresses health risks

    posed by dust inhalation

  • Reduce Damage & Wear

    Caused by abrasive waste materials

  • Only requires air supply

    & can be coupled to many existing extraction system

Current extraction solutions are a costly addition, and often require a bespoke machining centre. This can add in excess of 10% to the final purchase of such a solution, and are a necessity given ‘The Control of Substances Hazardous to Health Regulations 2002’ and the ’Provision and use of Work Equipment Regulations 1998 (PUWER)’

This high cost and H&S obligation can often prevent endeavours in machining of new, emerging materials for many - specifically those which can produce dust in large volumes. NIKKEN Kosakusho Europe Ltd have, therefore, developed a low cost, retrofittable solution to on-machine particulate removal. This ultimately enables you to widen the range of capabilities available in your portfolio. (Patent WO 2018/141972)

V-EX extraction solutions

Concept

The patented design has no moving parts, and requires nothing but a 6bar air supply. Using nothing but an air feed, the extractor multiplies the air flow from inlet to outlet, removing dust and particles from around the cutting tool and ejecting these at high speed.

The outlet can be coupled to a filter bag, filtration system, further vacuum pump, or simply a vent hose, depending upon application and material properties. The lack of moving parts and electronics means that the device can be used in both wet and dry applications, with a range of particle sizes, and has no problem dealing with conductive dusts.

The design is such that it is compatible with a huge range of machining centres, and can be retrofit with minor modifications. Similarly, if tool changing is required, NIKKEN can offer bespoke solutions to automatically remove the housing from the area needed to enable full ATC functionality.

Performance

Performance tests have been conducted with a 6 bar input pressure and 6mm diameter pneumatic pipe, providing an input flow rate of 2.5cmm. The outlet velocity was measured as 21.9m/s and a flow rate of 5.8cmm, with the suction flow representing 3.3cmm of this.

This indicates an air-flow multiplication of 2.32 (232%) times the input flow rate measured at the output, and an extraction rate of 3.3cmm or 55 litres/second.
