NCKType series precision CNC keyway machine tool

Basic automatic indexing type with semi open clamping and chip removal mechanism type

NCK Physical picture of CNC keyway machine tool

This machine tool has completely changed the old-fashioned lathe and internal lathe The concept of machining inner hole keyways with a planer combines the advantages of insertion, pulling, and planing The design is innovative and adopts CNC technology, unique inner hole centering process, and special feed principle. Its processing speed and accuracy are incomparable to traditional methods. It has good processing accuracy and fast speed, and can replace the through hole groove and non through groove of long and ultra long hole workpieces processed by slotting machines, internal lathes, and wire cutting machines.

At present, its excellent performance has been verified by users, and customers generally reflect that the machine tool has high precision, high efficiency, and is convenient and practical; Its overall performance has approached or reached that of German key slot machine tools; Some technical indicators, such as the machining length of the inner hole groove, have exceeded that of German keyway machine tools.

This machine tool is carefully designed, with a reasonable layout, compact structure, beautiful appearance, easy maintenance, and high degree of automation; Economical and practical, it is the best choice for processing high-quality, difficult, complex, precision long inner hole slots and ultra long inner hole slots Even the final equipment selection.

2、 Principles of Machine Tool Processing

1Precision ball screws are used for reciprocating and feed movements, and two ball screws are designed for reciprocating cutting and feed movements, which are distributed along the same straight line to perform vertical reciprocating cutting. The position design of the keyway machine with two ball screws allows forThe reciprocating cutting force always follows the centerline of the machine tool.

2The slide of the tool holder moves back and forth between two hard cylindrical guide rails on the machine tool, ensuring that the slide of the tool holder remains fast and stableHigh precision operation.

3The reciprocating axis and feed axis are controlled by integrated coding, eliminating the need for sensitive linear displacement measurement control systems The malfunction caused by it.

4Cutting oil is directly flushed and cooled onto the guide rod, single blade, and workpiece to be machined parts,Cooling and lubricating to reduce wear and tear, in order toEnsure machining accuracy,Improve production efficiency.

5、During the cutting process, the work platform remains stationary and the tool moves downwards for cutting.

6Grinding, cutting, and chip removal can all be automatically completed.
