Servo Tracking Flying Shear
Length accuracy is a motion story: encoder reads strip travel → servo matches speed → clamp and cut → carriage returns home before the next window.

Operation steps
Mount and scale the encoder
Mount and scale the encoder
The specification calls for an Omron encoder. Clean wheel contact and correct pulse-to-millimetre scaling keep length scatter under control.
Match strip speed
Match strip speed
The carriage accelerates until its velocity matches the strip. Film at contract speed so the return window is real.
Clamp, cut, covers
Clamp, cut, covers
Rear hydraulic cut with Cr12mov blade. Late clamp lets the strip slip; early clamp bruises the surface. Front/back bellows stay closed around the cut head.
Return home before next window
Return home before next window
At 25–30 m/min the return window shrinks. Hose drag chains must move freely; sticky plumbing fails before PLC gains can compensate.

The wide line shot gives context for where the shear sits. Keep the page title and SKU on the flying shear station, instead of retitling it as the host profile.
What's included
This line
Servo tracking flying shear: match-speed cutoff with 3.8 kW servo, 5.5 kW air-cooled hydraulics, rear cut, Cr12mov blade, Omron encoder, around 25–30 m/min.
Standard build
Stop-cuttrapezoidal shear,guillotineshear,pedalshear,outfeedstacker and tiletrim accessorieshave their own process pages.
Key details
Line speed
Match-speed flying shear cuts while the strip moves. Stop-cut shears halt the strip for each cut; the two stations belong in different process pages.
Note 2
This build uses a 3.8 kW servo.
