When it comes to fully processing machined parts using machines with powered tools, especially in CNC lathes, this tool sets new standards in percussion drilling and thread cutting.

The percussion drilling tool made by heimatec System Schwarzer

The innovative, powered percussion drilling tool made by heimatec System Schwarzer and designed for making inner and outer profiles is fully in line with the tradition of heimatec's exacting endeavour to manufacture high-precision products. This tool will enable you to make grooves and profiles of any kind at the utmost speed and with the precision of a clockwork using your machine tool (lathe).

Faster than comparable production processes

The job:                       Key grooves 6x14

The known:                  Machining using the broach   90 seconds

The tool revolver stays in its programmed position and does not make any Z-movements. The stroke movements of the slotting tool is determined by the tool drive of the machine. The stroke length is determined in the slotting tool. There is continuous feed in the X-direction of the tool revolver. The pitch or angle for the desired section can be freely selected and is positioned via the C-axis of the tool spindle.

Your advantages

                                   compact construction

                                   precision bearings

                                   all parts subject to wear and tear hardened

• no need to place workpieces in interim storage
• positioning and bearing tolerance can be determined
• high degree of dimensional accuracy and level of true-running coaxiality
• production of blind bores possible
• production of internal and external sections possible
• every kind of special tools on request
• all tools with coolant feed
  

Characteristics

One of the many advantages over broaching is that the tool has a high degree of stability, which means that it does not tend to run off centre during the slotting process. It is guaranteed that the sections maintains a position in respect of the reference surface of the workpiece which is in parallel with the axis. It is also possible to produce sections in blind bores. Compact construction of the tool heads with internal coolant feed.

Possible profile types

Grooves (e.g. parallel key groove), special profiles, such as key grooves, toothing, square, hexagonal, octagonal, dodecagonal, Torx, Surface Drive or even surfaces square-shaped, pentagonal etc.

Thread cutting using heimatec System Schwarzer

The job:                       Thread 12x24

The known:                 n = 1,800 rpm                         10.5 seconds

The optimum:            n = 5,400 rpm                        3.5 seconds

Your advantages

• The tool is virtually maintenance-free
• Centre and axis parallelism are adjustable
• Conicity against groove depth can be adjusted (depth of profile)
• Constant cutting speed
• 2/3 rotation working stroke, 1/3 return stroke
• High cutting speed V=200 m/min and above
• Lifting path possible up to 2.3 mm (for thread cutting or to machine radiuses at the end of a groove)
• Stroke lengths in groove/profile percussion drilling and thread cutting: 12, 18, 26, 30, 36 and 42 mm

Additional feature

For thread cutting, the infeed movement is carried out along the X axis only at a continuous velocity of 20 mm/min.

There is no need of turret movement along the Z-axis.
