Manufacturing

Industry: Aerospace

System: Work Platform Lift Systems

# Axis: 4

Valve: Servo

Description: This system used (4) 72" stroke hydraulic cylinders attached to the main platform of an incline ramp. The incline ramp could move in a circular motion. The ramp would be positioned next to Boeing 747 cabin doors and then the main platform would be elevated to a cabin door entrance. The cylinders were tracked to keep the platform level. Once in position, the system hydraulics were turned off and workers could proceed up the ramp and into the aircraft. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Metal Manufacturing

System: Metal Punch

Axis #: 3

Valve: Proportional

Description: Steel plates were placed on a moving table. The table had 3 tracking cylinders attached to a platen. It was very important that the table remain level during movement and punch cycle. If the system failed, the hydraulics had to be turned off and controlled to prevent the table from twisting.

The table would move down to a set of punch dies. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Plastic Manufacturing

System: Plastic Rail Drill Table

Axis #: 1

Valve: Proportional

Description: System used a 72" stroke hydraulic cylinder with Temposonics. A plastic rail would be mounted on a moving table. The table would move to user defined targets. A drill press would come down on the material and drill a hole. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Power Generation

System: Turbine Fin Pitch Controls

Axis #: 1

Valve: Servo

Description: Moved fins on water turbines to match water flow.

Industry: Steel

System: Steel Shear Outfeed Tables

Axis #: 4 to 8

Valve: Proportional

Description: In steel rolling plants there is usually a table positioned at the rear of a metal shear. A coil of steel is placed before a set of rolls. The coil is un-reeled through these rolls and straightened before the shear. The table was lifted in the past by jack-screws. The table had a total load capacity of 10,000 lbs. By changing the jack-screws to hydraulic servo control cylinders, the lifting capacity changed by a factor of 6. All cylinders had to be tracked so the table would remain level when moving up and down. Tracking tolerances were kept at .020" between all cylinders. Productivity increased 6 fold.

Industry: Wood Products

System: Overhead End Dogging Machines

Axis #: 3-8

Valve: Servo or Proportional

Description: Primary log breakdown. Logs fed to saws and/or slabber configurations based on centerline of machine. Units used log charging carriage that moved logs through a scanner. Saw/slabber sets based on scanned log diameters. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Wood Products

System: Horizontal Resaw: Single, Twin, and Triple Saw Machines

Axis #: 1-3

Valve: Servo or Proportional

Description: Cut slab boards fed to saws positioned on a horizontal plane. Saw/s are moved up or down. Saw/s could be stationary and the infeed and outfeed tables to the machines were moved. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Wood Products

System: Vertical Resaw: Single, Twin with/without Tracking Linebar, Pickers

Axis #: 1-6

Valve: Servo or Proportional

Description: Cut slabs and/or cants are fed to saws positioned in a vertical plane. Wood is referenced to the left or right of the saws. Saws maybe fixed and a moveable linebar position the wood before the saws. Devices that divert unusable wood called pickers will move with the linebar positions or saws. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Wood Products

System: Board Edgers with/without Pickers and/or Linebar

Axis #: 2-8

Valve: Servo or Proportional

Description: Cut slabs are feed to positioned vertical circle saws to cut boards used in housing construction, cut up plants, and furniture manufactures. The boards might be positioned by hand, or linebar. Pickers are used to separate the waste wood from the board. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Wood Products

System: Board Optimizer

Axis #: 4-8

Valve: Servo or Proportional

Description: Cut slabs are feed through a laser/optical scanner and positioned, fed and cut automatically through a board edger. Pickers are used. Hydraulic Temposonics feedback servo positioning cylinders used. Scanning and positioning are completed with one motion.

Industry: Wood Products

System: Planer Roll Height System

Axis #: 2-3

Valve: Proportional

Description: Planer infeed and outfeed rolls using soft rolls are positioned to different thicknesses of boards. The rolls are sequenced as a board is fed through the planer. Using soft rolls decreases manufacturing defects on high priced boards. Hydraulic Temposonics feedback servo positioning cylinders used.

Industry: Wood Products

System: Debarker Ring Control

Axis #: 4

Valve: Proportional

Description: Debarker Ring knives are moved to match the size of an incoming log. As the log is debarked, the ring moves. Due to ring positioning manufacturing defects are decreased and maintenance is reduced. Hydraulic Temposonics feedback servo positioning cylinders used.
