EV  4A

EV 4A is a CNC corner cleaning machine for PVC frames with 4 interpolated axes and automatic cycle which, when suitably configured, is able to recognize the size of the profile to be cleaned. It has a 275 mm diameter blade which allows, with different work programs, cleaning the outer corner on various profiles. EV 4A also has top and bottom units with knife for cleaning the welding beads plus top and bottom units with knives for cleaning the inner corners. Machining of the inner and outer corners can be completed with the top and bottom drilling/milling units for cleaning the corners or gasket grooves. The machining units can be programmed independently from each other via a CNC PC which controls programming of the profiles and machine operation (manual or automatic mode). When the machine is suitably configured with the necessary tools, it can handle all types of standard profiles including acrylic and coated profiles. EV 4A is available in three models: a manual version, a semiautomatic version (with turntable) and an automatic version (with turntable and outfeed table).

Internal reference and external clamping

The precision guaranteed by Someco in the PVC corner cleaning machines is obtained through the use of an N/C stop that allows the frame to be positioned in the machine by making reference to the internal corner of the frame. This ensures accurate centering and no limitations due to any difference in width of the profiles making up the frame. In such solution, efficient clamping of the corner is through the independent action of two clamping systems (horizontal and vertical) mounted on two slides. As these slides move along two perpendicular directions, they refer the corner to the machine working direction.

Ergonomic design and safety

Great care has been taken over the ergonomic aspects of the machine: the special machine look is a result of the synthesis of objective regarding safeguarding and accessibility. The machine has provision for connection to a swarf exhaust system in both the area mainly involved in cleaning (knife for cleaning around the outside of the corner) and the bottom area of the machine where the swarf tends to build up.

Frame handling system

The objective of concentrating all the frame handling functions in a device that ensures highly dynamic positioning phases and accurate positioning of the product in all phases of the work cycle has been achieved thanks to the 4- axis manipulator. Such system is independent from the actual corner cleaning machine where the tools for the cleaning cycle are located. As the device has controlled axes, the product feed, rotation and unloading cycle parameters are optimized automatically by the CNC in relation to the dimensions and weight of the frame to be handled, thus ensuring minimum cycle time with maximum accuracy and care of the surfaces in contact with the machine.
