• Semiautomatic machine with CNC for broaches VZ-780F4-01

Stretching is an expensive tool that requires periodic sharpening. For sharpening broaches our company offers a special semi-automatic with CNC VZ-780F4-01, which allows you to perform the following types of treatments:

  • Formation of the profile of teeth and flute grooves on round and flat broaches (including the type "Christmas trees" and "swallowtail");
  • Sharpening of the teeth of round and flat broaches along the front surface;
  • Sharpening of teeth of flat broaches on the back surface;
  • Binding of the grinding wheel to the machine coordinate system of the semi-automatic machine;
  • Shaped editing of the grinding wheel.

This model of semi-automatic machine is based on the machine VZ-780F4 and differs from it with the possibility of installing products of longer length (up to 1000 mm) and weight (up to 100 kg). The nodes are controlled by the SINUMERIK 840Dsl (SIEMENS) CNC, which allows you to control the positioning of the 5-axis axes. Precision of positioning and processing is achieved through the use of digital drives SINAMICS S120 with engines of the 1FW6 and 1FK7 series.

Moving along rectilinear axes is carried out by synchronous motors along closed guides. Radial movement of the spindles of the grinding head and the head of the product is performed from the built-in circular synchronous high torque motors with position sensors on the final links. The shape of the grinding wheel is adjusted by a shaped diamond roller in an automatic cycle. The tailstock is moved by a hydraulic drive. Grinding of broaches is performed with the use of coolant, which ensures the highest quality parameters of the treated surfaces.

The semiautomatic machine is completed with the system of preparation of control programs (SPM), developed at our enterprise. The system works on the personal computer included in the semiautomatic system. All actions when working with SPM are carried out using the controls integrated in the operator panel.
