Magnetic milling cartridges provide clamping of the workpiece for a wide range of vertical or horizontal processing.
Manual work often requires multiple instruments or variable clamps, visas or screws during the various milling phases. Replacing the manual clamping with magnetic milling cartridges eliminates the inefficiency of conventional working restraints. They provide better parts availability, reduced vibrations for machining accuracy, five-sided availability and reduced setup time, which adds up to improved workflow efficiency. This makes them well suited for clamping workpieces for a wide range of vertical or horizontal machining applications, including, but not limited to, profiling, face milling, milling, milling, grinding, surface grinding and drilling.
Construction and control
Magnetic milling chucks are designed using high-power ceramic or neodymium permanent magnets, which are typically controlled by permanent magnetic or electromagnetic magnetic technology. The surface of the magnetic pole is made with a steel structure, facilitated by the use of slotted grooves that allow you to clamp the colored parts. The poles are configured in longitudinal or square geometry. The distribution of the poles provides a uniform magnetic force over the entire surface area of the workpiece. The magnetic field is designed in such a way that the upper plate of the cartridge does not have any wandering magnetic fields, which encourages the collection of chips to the workpiece and the cutting tool.
Magnetic milling chucks can be adjusted in two ways: mechanically with a lever or electronically using a chuck regulator. The type of permanent magnet uses a lever to turn on or off the magnetic field. It does not require power supply. An electropolar magnet type uses a cartridge DC controller to energize or de-energize the magnetic field, which takes about 1 second. However, the work does not require electrical power, which gives this type of control the function of protection against failures.
Raster blocks and double magnets
To increase the variety of machining operations that are suitable for working with magnetic work, you can use risers or pole extenders using a magnetic cartridge to increase availability and reduce interference. These blocks are essentially opposing, which raise the workpiece above the surface of the magnetic cartridge. Riser blocks allow the workpieces to be positioned above the chuck so that end-to-end machining operations are completed without damaging the magnetic surface. It also allows side and rear cutting. Pole extenders and self-tapping poles can be fitted with magnetic modules for greater flexibility. Double magnets can be used with a magnetic cartridge to provide tool clearance and uniform clamping in certain areas. They have a clamping force of 1700 LB (7.6KN) and a depth of field of 15 mm. It can be connected in series to ensure uniform clamping on large parts.
