Innovative system of adjustment of laser tools

15/11/2003
In addition to the transmission system of probe by radio for machining centres (see MU 18 - September 2003), Renishaw introduced the new system of adjustment of tools in the EMO laser NC4. Ultracompactas transmitter and receiver units for the adjustment of tools laser and a size of only 30 mm (diameter) x 35 mm (height), the NC4 system allows a rapid adjustment of tools without contact and detection of broken tools on machines that previously did not allow this kind of application.

NC4 system provides a highly repetitive setting in separations of systems of up to 5 meters. According to the distance of separation, it is possible to measure tools with a reduced diameter of 0.2 mm at any selected point of the laser beam and detect broken tools of up to 0.05 mm in size.

Before the introduction of the NC4, due to the size or the machine configuration, adjustment of tools contactless systems were incompatible with some machine tools, so limiting the route of the axis of the machine or using expensive and complex switches of limitation could only be installed. The ultra-compact system of adjustment of tools NC4 has overcome these problems and provides all the advantages of contactless adjustment without compromising the performance of the machine. NC4 system is also very suitable for installations on machines already in use.

Housed in a robust stainless steel, the system of adjustment of tools Laser compartment NC4 an IPX8 rate and works in the strictest of machining. MicroHole protection system uses a continuous jet of compressed air which provides uninterrupted protection against taladrina, graphite and entry of coolant, even during the measurement routines. If fails the supply of air, a new and innovative device for sealing security keeps pollution and protection IPX8.

New technique of compensation

The new Renscan DC (dynamic compensation) of Renishaw patented measuring technique allows operators of MMC measurements at incredibly high speeds, but with an accuracy that previously only could be achieved at low speeds.

Available in the UCC range of universal MMC driver of Renishaw, Renscan DC can be combined with any of the probes of copied from Renishaw, allowing its use in a wide range of MMC, including many machines that could not previously performed copied at high speed.

Renscan DC is a method of compensation based on surfaces that compensates for the dynamic measuring errors generated in the copied at high speed. These trade-offs are derived easily through a simple process of measurement of each surface of the piece two-speed of copying different: a slow and one fast.

It is based on the fact that although the dynamic errors are very difficult to predict, are generally repetitive. Through an efficient 'allocation' of dynamic errors induced by each surface of the component, it is possible to accurately measure the following high-speed parts, provided that they have the same nominal size and are in the same area of the machine.
