Screw Plug System Type Hot Press Platen CNC Machining

We are providing such plug system platens to Italy's largest laminating press
maker and which has the extreme high quality requirement;deep hole must be
drilled from longitudial direction and platen thickness is only 37mm and 20mm
diameter drilling must have precise tolerance in the middle joints,so we are
providing high precise CNC gun drilling;as they are screw plug system plug
sealed and high pressure working,so we must have a tight screw basement hole
size,then we can have a tight screw to hold on the plug then pressure.In a word
those platens are all by tight tolerance produced and quality control is
extremely strict:

The quality requirement has been detailed from Raw steel plate grade and source
to finished hot platen packing:

Raw steel:Q345B/A36/S355JR/S235JR SIZE:1300*2500/3000/3500*40mm

Deep hole diameter:20/22/25/28/30/35mm And drilling from both ends and middle
joints tolerance within 1 mm

CNC machining for width and length are applicable in order for precise assembly

Surface grinding quality has been specific higher requirement for RA 0.8
Parallizm 0.1mm Flatness:0.10mm,any thickness minus tolerance and defects are
not allowed

Surface RA 0.8 Parallizm 0.1mm Hydraulic Testing:100kg/cm2 holding time 20
munites temperature tolerance within 3 c-degrees

Production flow:Rough surface milling-deep hole drilling;slotting;weldings;CNC
precise milling;rough grinding;CNC grinding-testing-packing-container loading
