Measures to reduce the downtime of your machines are significantly more worth while than chasing seconds in the actual machining process. What matters is to keep the machines running. And that’s when you need an interface that gives fast setting-up.
The Macro system is just that kind of interface. Setting-up in parallel away from the machine while it is working and then setting up in a matter of seconds in the stationary machine. Important for long runs, but crucial for the profitability of short runs or one-piece production.
Among users world wide, the Macro system is a byword for precision. And with good reason, since very single Macro product is thoroughly checked before it is dispatched. But precision can be graded too. So Macro products are “classified” on the basis of accuracy, material and life, while full compatibility is retained. Even so, it is worth remembering that the accuracy of a system is determined by the product with the lowest classification.
The broad product range offers a multitude of solutions for quick and precise clamping of the workpiece in the machine. Manual or pneumatic chucks, pallets from 54x54 mm to 180x180 mm, and measurement and inspection units.
Vibration during machining has a crucial effect on production capacity. VDP allows machining with higher cutting data and better utilisation of the available machine capacity.
The Macro range includes a number of vibration-damped chucks. VDP brings a considerable increase in productivity within reach.
Usually the workpiece is mounted directly on the pallet, which then carries the workpiece throughout the entire machining process – from machine to machine if necessary.
The reference elements are primarily intended to be mounted on the fixtures or vices in which the workpiece will be clamped. The reference elements are significantly thinner in order to limit the total construction height.
A number of the Macro products have been adapted for System 3R’s patented expanding mandrels in the 3Refix positioning system.
3Refix Ø10 in pallets for quick and precise repositioning of the workpiece for further processing, for example after heat treatment.
3Refix Ø20 in chucks for quick and precise positioning on the machine table.
