Machining services
Implementation of all machining operations on CNC-controlled lathes (CNC turning) and milling machines (CNC
milling), sawing on CNC band saws (CNC saws). The certified machining company in Neumuenster
makes metals in wage labor and industrial contract manufacturing and production of small and large series of
rotating parts and milling of all metals, castings and aluminum and plastics. The
precision machining
is performed in computer-controlled machining centers for the industry in Northern-Germany, this allows precision
turning and milling and highly accurate production of precision turned parts in our machining company.
The separated cutting, which is called in accordance with DIN 8580 and shaping machining referred to in any
technology of machining all machining operations in which the user-supplied material is brought into the
programmed and the desired shape by metal material is removed in the form of chips. The manufacturing process
is defined in DIN 8589 in Germany as machining and certified according to ISO.
Within the five major groups of industrial manufacturing processes (cutting, coating, grinding, hardening and
lapping) the CNC machining is a computer-controlled machining process. The term
CNC machining,
milling or machining services is now generally used in the context of removing metal, although the provisional
machining of all other tempered and resistant materials such as stainless steel, brass, bronze, aluminum,
polyurethane and NBR and plastics is one of them. To the medium-industrialization and the accompanying
development of the coincident series production has contributed significantly. From the automated milling
machines and machining centers in the metal processing industry, today's profession of qualified workers and the
developed cutting machine operator.
However, the manual machining and hard turning processes are cutting, so that they can be classified in the
subgroup of advanced manufacturing technology in Germany and Hamburg. A basic principle of milling and turning
based on the turning (CNC turning) and
milling
(CNC milling)
tool in a dimensionally accurate, the polished surface of the workpiece and the subsequent removal of a thin
layer of material by means of a measuring machine. The plant material must always be a little harder than the
material processed by the chipper. Sufficient for processing relatively simple rotating stainless steel materials
or inserts as starting material for the German CNC machining technology.
For harder workpieces special high tempered tool steel, diamond, tungsten carbide, WIDIA, sintered materials,
cutting ceramic or silicon carbide are used as cutting tools. The parts to be milled or processed may have a
well defined and controlled geometry, which is used for example for turning and cutting (CNC band saw for metal
machining with own material stock), or by drilling into consideration, or it may be irregularly shaped, such as
grinding and lapping, which can represent a machining with geometrically defined cutting tools not in the
catchment areas of Kiel, Luebeck, Hamburg, Rostock and northern Germany.
Machining
The machinist is directly involved in the production, planning and machining of components. Thus, configure both
the individual as well as manufacturing for mass production and contract manufacturing, in
implemented machining services
and the control of them either conventional or other computer-controlled machine tools such as milling systems,
rotating machinery systems, grinders, lathes and automatic boring machines. The minimum requirement for a
professional qualification like an assessment and analysis of the technical feasibility of manufacturing jobs is
completed, what will be used as a source of information, the construction drawings or technical documents in
order to select the appropriate method of manufacturing.
In the further course the production processes are planned in detail, in order to proceed in accordance with the
economic, schedule and quality requirements into production. The machining technician (chipper) adapt the
programs for numerically or computer controlled CNC machine tools and manufacturing systems and they monitor the
production in the machining company in three layers. In multi-shift operation skills are also required concerning
the quality management of
CNC manufacturing,
the job work, documentation and various safety devices to monitor a schedule execution of a contract. Other
required skills are the maintenance and quality control of manufacturing systems, computer controlled measuring
instruments based on non-contact basis (laser scanning) can be controlled by the operator.
CNC turning
Very sophisticated mechanical parts are manufactured using computer controlled lathes in a relatively short time
in large numbers, using the technique of turning generally used with CNC (Computerized Numerical Control). With
these machines, the programs are written by the operators themselves, which are read by the machine first and
then subsequently reacted precisely. This can produce on the lathe (cnc lathe) more shapes than the former
manual milling heads. Even curved or pyramidal and multi-dimensional forms are included in the
automated turning processes
so that mass production can be provided. For companies in Germany, which produce different workpieces in larger
amounts, a turning center for manufacturing reasons is essential.
CNC milling
From the blank is produced by
milling a workpiece
or more complex assemblies, the cast part in a multi-axis vice (jig) is clamped on a router table. The cutting
tool, the cutter or cutter head, is gripped by hand into the threaded spindle and then fixed and later the
carriage moves with the work piece in the direction of the cutter.
The milling head bears on the exact surface of the workpiece just as much material as was previously determined
by the requirements of the customer.
In order to ensure nevertheless proper milling, whether or not the rotational speed of the milling cutter of the
milling part and the calculated feed must be set before any cutting operation in addition to the processing speed
further. When machining milling parts there is a fundamental difference between two methods; namely the certified
quality control on the one hand, and on the other hand, the monitoring by subsequent measurement, which is
implemented by qualified staff of the machining company.
