PRECISION ROLL GRINDING & BALANCING
Intech Machine grinds and balances all paper machine roll and cover types. Pre-grind and post grind profiles are taken using our customized Pro-Mic Roll Measurement System. Pre-grind profiles are analyzed to provide feedback to our customers regarding operational wear, or loading issues that can be corrected to optimize performance and extend grind cycle frequencies. A Gem Super Finisher is also utilized to assure consistent surface finish requirements.
ISO 21940 G Grade specifications are used for balancing rolls on our SCHENK balancing machine. Most paper machine rolls are balanced at G1.0 specifications with some sensitive rolls being balanced to G.1 specifications. Intech Machine co also offers a unique service of checking baseline vibration analysis of bearings to minimize the chance of a defective bearing being placed in service.
NEW ROLL MANUFACTURE
We put our decades of experience in repairing and maintaining rolls into our engineered new roll manufacturing process. Intech Machine co designs and manufactures new rolls including press rolls, wire rolls, felt rolls, and reel spools. We understand that most replacement rolls operate at parameters drastically above their original design. Intech Machine co will determine today’s operating environment and incorporate it into a suitable design for the future.
Intech Machine Co,
can design, fabricate, and manufacture a variety of precision rolls, critical rolls, and process rolls based on your requirements, with or without existing manufacturing prints or OEM drawings. Our engineering team can reverse engineer a new roll to match or exceed your current roll’s performance. Our process includes taking detailed measurements of all critical dimensions, creating the CAD drawing, proposal of design enhancements, manufacturing in-house, and managing the process from start to completion.
