Why the Cylinder Seized After 30 Days: What Happens Inside A Ø32 mm pneumatic cylinder on a clamping station. It cycled every 6 seconds. After about a month, it stopped moving. The piston was stuck…
Overlapping the Stations: When Sequential Cycle Time Becomes the Bottleneck A pick-and-place cell. The robot picks from the feeder, moves 300 mm, places at the station, waits for the operation to finish, then returns. The…
The FRL That Flooded the Floor: Bowl Drain and Water Accumulation A filter-regulator-lubricator (FRL) unit that dripped water onto the floor every shift. The customer thought the bowl was cracked. The bowl was fine. The…
Why the Reed Switch Fell Off: A Close Look at the Mount A reed switch (magnetic cylinder position sensor) on a pneumatic cylinder. It clipped onto the cylinder’s T-slot with a screw and a plastic…
Installing the Machine: The Day Before the Operator Shows Up The machine shipped on a flatbed. The riggers put it on the customer’s floor. The leveling feet were adjusted at the factory — but the…
The Wear Strip That Lasted a Month: Material and Geometry Over Time A belt conveyor carrying plastic parts. The belt ran on a steel pan (a flat steel bed under the belt). After one month,…
Reading the Pressure Switch Spec Sheet: Beyond the Setpoint A pressure switch on an FRL regulator. Setpoint: 6 bar. The switch was supposed to signal the PLC when the system reached operating pressure. Instead, the…
Field Notes: The Sensor That Chattered Near the VFD Week 3 of commissioning. An analog proximity sensor (0–10 V) measuring web tension on a converting line. The reading was jumping ±2 V even when the…
Vacuum Gripper: The Setup That Worked vs The One That Didn’t A cardboard box handling cell. The robot picks boxes from a conveyor and places them on a pallet. The original gripper dropped a box…
The Cylinder That Wouldn’t Retract: 48 Hours on the Bench Day 1, 9 AM. The customer calls: the clamp cylinder on the packaging line extends fine but won’t retract fast enough. The extend takes 0.8…
Design Review: GT2 Timing Belt on a Linear Axis This is the review notes from a linear axis that started slipping under load. The belt was GT2, 6 mm wide, on a 20 tooth pulley,…
The Machine That Missed the Cycle Time by 3 Seconds We designed a machine for a customer. The required cycle time was 12 seconds per part. On paper (in the design calculation), we summed the…
Sensor Bracket Design: The Quick Reference A photoelectric sensor on a 1 mm bent sheet-metal bracket. The bracket flexed under the vibration of a nearby press. The sensor drifted 2 mm in three months. The…
Five Things Everyone Gets Wrong About Gripper Force We crushed a batch of 500 plastic housings before anyone asked the right question. The pneumatic parallel gripper was spec’d at 400 N force. The parts were…
A 6-Meter Conveyor Frame: From Drawings to Machined Pads This is the story of a welded conveyor frame — what we drew, what the shop welded, what warped, and what we changed for the next…
