The combined machine tool is a semi-automatic or automatic special machine based on common parts and equipped with special parts and fixtures designed according to the specific shape and machining process of the workpiece.

The combined machine tool generally adopts multi-axis, multi-tool, multi-process, multi-face or multi-station simultaneous processing, and the production efficiency is several times to several tens of times higher than that of the general machine tool. Since common components have been standardized and serialized, they can be flexibly configured as needed, reducing design and manufacturing cycles. Therefore, the combined machine tool has the advantages of low cost and high efficiency, and is widely used in mass and mass production, and can be used to form an automatic production line.

Combination machine tools are generally used to machine parts of boxes or special shapes. During machining, the workpiece generally does not rotate. The rotary motion of the tool and the relative feed motion of the tool and the workpiece realize drilling, reaming, boring, reaming, boring, milling plane, cutting internal and external threads, and machining the outer circle. And end faces, etc. Some combination machine tools use a turning head to hold the workpiece to rotate, and the tool can be used for feeding motion, and can also realize the outer circle and end surface processing of some rotary body parts (such as flywheel, automobile rear axle half shaft, etc.).

Since the 1970s, with the development of indexable tools, fine-tooth milling cutters, automatic pupil size detection and automatic tool compensation technology, the machining accuracy of combined machine tools has also improved. The flatness of the milling plane can reach 0.05 mm / 1000 mm, the surface roughness can be as low as 2.5 ~ 0.63 μm; the pupil precision can reach IT7 ~ 6 grade, the pitch precision can reach O.03 ~ O.02 microns.

Special machine tools have evolved with the rise of the automotive industry. Some parts in a special machine

Rigid PP/PE/ABS/PC Pelletizing Machine

Rigid PP/PE/ABS/PC Pelletizing Machine

raw material:PE plastic film

final product: PE granules

output:100-800kg/h

cutting type:water ring

Components included in plastic pelletizing machine :

1.feeding conveyor 2. film compacting machine 3. screw barrel 4.fast speed double post non-stop hydraulic screen changer 5. water flush pelletizing system 6. water cooling trough 7.Centrifugal dewatering machine 8.vibration screen 9. conveying blower 10. store silo

Advantages of this plastic pelletizing machine :

PE/PP recycling granulating machine is special equipment for the PE PP film recycling granulating, it equipped with comacting machine which cound pre- compact the film into smaller granules, then easily feed into screw barrel of extruder, its efficiency is high and can improve production capacity and save labour cost.

it has two vacuum exhuasting mouth on extruder barrel which can fully vent the moisture in the material and hence the final granule quality will be very perfect.

at the end of screw barrel, it equipped with double post fast speed hydraulic non -stop screen changer which can effetively filt out the dirty in the plastic melt.

the pelletizing adopts water flush pelletizing which is easier to operate, and the shape and appearance of granule is good.
