CNC machine construction – great performance capacity
thanks to independent axis groups
and high-speed milling spindles
This CNC machining centre gives you the power and functions of two machines while requiring just one control system and one operator. In addition, this type of CNC machine is ideal for automated feeding of components by means of a linear portal or robot. These CNC machining centres are true champions when it comes to their overall performance! Machines made in Germany, developed for plastic processing or processing workpieces made of composites, modelling materials and aluminium. The CNC machines are available in different sizes and versions.
The performance capacity of the CNC machining centre with multiple components makes it one of the most effective versions for processing workpieces in mechanical engineering. It makes it possible to achieve cycle times that are otherwise difficult to achieve with two machines and two cycles.

High-precision 3D machining: CNC milling and cutting and with several axis groups and tools simultaneously.
The 5-axis CNC machining centre with two axis groups (shown) has two milling units that operate independently and each have a high-speed milling spindle
The design with two or more axis groups offers many benefits when it comes to processing workpieces. First of all, the workpiece can be processed from several different sides simultaneously. Second, different tools can be used at the same time. This method greatly reduces the cycle times.
Different table versions are also possible. In the case of a CNC machine with two tables, two workpieces can be processed differently at the same time. The additional benefit of having two tables is that the tables can be linked together to create one large table for large components.
It is also possible to process several workpieces with a CNC machine that has one table. Depending on the size of the table, two or more components can be processed on one table, with a milling cutter holder mounted on the table in each case.
Selecting the high-speed milling spindle
When it comes to selecting the high-speed milling spindle, there are different benefits depending on the type of spindle. If an axis group is equipped with a double-shaft spindle, the tool changing time can be very greatly reduced. The second tool is deployed within a very short space of time by rotating the spindle onto the second shaft end. Two different tools can be used for each double-shaft spindle.
In the case of an HSC spindle with one tool, the tool changer that moves at the same time provides 12 tools for each milling spindle.
The workpiece clamping fixture can also be equipped with other axis groups, such as drilling units.
Performance capacity and machine construction
HG GRIMME SysTech – Made in Germany
In our factory in Wiedergeltingen in southern Germany and our dedicated design department, we specialise in constructing CNC milling centres and other CNC machines. We construct all types of CNC machines with several axis groups. These include CNC milling machines and CNC cutting machines.
The combination of axis groups operating simultaneously enables the CNC machining centre to quickly mill or cut complex shapes from a single workpiece. The workpiece is processed three-dimensionally at high speed. The movements of the axes are coordinated by the CNC control system. This ensures that repeatable results are produced on the workpiece with absolute precision.
Flexibility in CNC machining: efficient CNC machining of large components with linked machine tables and different table versions
Depending on the customer’s requirement and component, several axis groups can either work on one large component or work simultaneously on two different workpieces. The machine tables on tandem machines can be linked together for synchronous machining on one component, thus creating one working table for large-sized components. If the intention is for each axis group to work on one component on its own, the working tables can be separated and fitted differently.
Thanks to our modules, the CNC machining centre can operate with lots of different table versions. If the CNC machine has two tables, they are equipped with a divider panel which shuts automatically. Alternatively, shuttle tables can also be constructed. With shuttle tables, the components are loaded outside the cabin. This means that the machine operator can fit different workpieces outside the CNC machine alternately and without any risk.
An optional conveyor belt in the cabin conveys the chips out of the machine into a collecting container. The conveyor belt shortens the cleaning times for the operator and therefore significantly boosts the great efficiency and productivity of the machine. The chutes in the machine ensure that the chips slide down and are collected in optimum fashion.
This particular design of machine, a CNC machining centre with several axis groups, is ideal for applications in the aerospace industry, the automotive industry and in manufacturing precision components from different materials.
