CNC machining centre
The term CNC-machining centre describes stationary CNC-controlled tool machines. Depending on type and direction of the workpiece processing various executions are possible. Often the name is shortened with "CNC" or "BAZ".
Structure of a CNC machining centre
Basic construction forms of machine tables:
There are many other special solutions and clamping systems but those are the ones one frequently comes across.
CNC-machining centres can be divided in 2 basic construction types:
Here there are as well special versions.
The units actually needed for processing can be found on unit supports. Those can be e.g.:
Meanwhile this designation as synonym for CNC-controlled stationary tool machines has become a standard term ,so that it is partly found in specialist journals and literature, too.
Todays CNC-machining centre developed from 2 kinds of stationary CNC-controlled tool machines - the CNC-router and the PTP-boring machine.
The CNC-router developed from the classical router, which was able to produce free moulded workpieces by the use of stencils. In the 1960s the japanese manufacturer Shoda Ironworks launched the first CNC-controlled router for wood processing. Shortly thereafter the first european CNC-machine was marketed by company Bulleri.
Parallel, since the beginning of the 1970s different companies developed PTP-controlled boring machines; in colloquial German these machines were not called CNC. In many European and Asian countries the term "PTP-machine" or "Point-to-Point" has become established and is partly used instead of the term "CNC-machining centre", even if the machine has a milling aggregate and a continuous path control.
In the mid- to late 80's the prices of computer technology dropped through mass distribution of home computers which as well had a significant influence on computer-controlled machines.
By this time many other manufacturers introduced new machine generations to the market where it hasn't been possible to spot a vast difference between CNC-routers or PTP drilling machines.
The manufacturer of PTP-drilling machines only offered router head and if necessary with further unit (e.g. Biesse, Morbidelli, Weeke) The manufacturers more specialized on CNC-routers e.g. Maka, Reichenbacher, SCM) equipped the machines in addition with drilling units and further units of (e.g. lock case milling aggregate
Because of the necessity to integrate several function units in one machine, to a great extent, the use of aggregate supports gained acceptance.
In the late 80's the companies Homag and IMA brought nearly simultaneously CNC-stationary machine with edgebanding machines on the market. Here the term "CNC-machining centre" has been used in pamphlets.
Shortly after the initial introduction of the word and the simultaneous distribution of CNC-controlled multi-function machines the name "CNC machining centre" has established itself for all stationary CNc controlled machine tools in the woodworking production.
