MILLING & DRILLING

Precision clamping equipment as a prerequisite for rational automation

The use of optimum clamping technology is the prerequisite for the highly efficient production process in the field of milling and drilling. Here the focus is on universal clamping systems and multi-sided machining with multiple clamping. The development and manufacture of these and other precision clamping devices has been part of SPREITZER‘s core business for decades. This also includes the extensive field of modular construction systems, special fixtures and rotary unions.

Clamping systems differ not only in their design, size and function, but also in the type of their drive. In addition to mechanical drive, electrical, pneumatic and hydraulic versions are thus also available, which can be integrated into automatic workpiece change intervals. The development and further development of different basic models, which can be modified modularly for each specific application, is therefore the prerequisite for rational production. The following is an excerpt from the product areas
from SPREITZER.

Application in the field of MILLING & DRILLING

Our core competence lies in mechanical, pneumatic and hydraulic

  • Special clamping devices for machining centers and special machines
  • Special clamping devices on rotary transfer machining centers
  • Drilling jigs

Depending on the application, we supply special clamping fixtures together with matching NC rotary table and counter bearing for the
Complete machining on modern processing machines.

Furthermore

  • Welding fixtures
  • Grinding jigs
  • Measuring and testing devices
  • Mounting devices

can be delivered.

This flexible system is equally suitable for the processing of small series as well as large series. The modular clamping system based on a drilling system has three different grid types. In this way, clamping and support elements can be combined to create a perfect and repeatable fixture whose modules also have the advantage of being reusable.

The basic elements of this system include clamping cubes, clamping cuboids and double angles, which are made of vibration-damping nodular cast iron. Clamping plates, on the other hand, are made of quenched and tempered tool steel. The surfaces are hardened and precision ground. As further accessories for distortion-free and exact clamping, various mounting elements such as support strips and stops can be used.

The high precision of the clamping elements represents absolutely exact machining within the specified tolerance range according to “ISO” standard, even in the rotational axis. SPREITZER centric clamps are considered the perfect precision solution for multi-axis CNC machining centers as well as for conventional milling and drilling machines.

The robust and durable designs provide high inherent rigidity and clamping force. A requirement for precise machining, even at high cutting pressure. Longer tool life and increased efficiency in the work processes are the result.

This heading includes, among others, versions of various machine vices that perform a so-called “third hand function”. In this way, the next workpiece can already be prepared, for example, when the spindle is moved on. A fixed center jaw and hydraulic clamping are further options of the equipment.

Multiple clamping systems “MMS” were developed for simultaneous clamping of several workpieces and can be combined with centric clamps.
Three-jaw chucks “DBF” are designed as precision spiral chucks, with high concentricity, according to DIN 6350 and are also offered with a mounting base plate. The repeatability and pairing accuracy is 0.01 millimeters.

In order to be able to quickly exchange clamping devices and fixtures of any kind with repeat accuracy in just a few steps, these zero-point systems were developed. The positioning repeatability is 0.005 to 0.01 millimeters.

This clamping technology differs essentially from mechanical or power-operated clamping technology in its form of energy – magnetism. However, the basic principle always corresponds to adhesion by means of large-area support. Setup time can be reduced to a minimum with this technology.

Magnetic clamping technology has always been used in surface grinding machines, cylindrical grinding machines, eroding machines and in measuring technology. However, this efficient clamping technology is also being used more and more in the milling and drilling sector.

This clamping technology differs essentially from mechanical or power-operated clamping technology in its form of energy – the vacuum. However, the basic principle always corresponds to adhesion by means of large-area support. Setup times can be reduced to a minimum with this technology.

The vacuum plate has the advantage of also positioning “non-ferrous metals” safely. For pressure-sensitive or bulky components, vacuum plates also offer an optimal alternative.

This clamping technology differs essentially from mechanical or power-operated clamping technology in its form of energy – coldness. However, the basic principle always corresponds to adhesion by means of large-area support. Setup times can be reduced to a minimum with this technology.

The freeze-clamping technique is independent of the material and is particularly suitable for pressure-sensitive or bulky components. This technology also works with relatively small workpieces and contact surfaces.
