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
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 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.
