Abstract

Lathe control systems and methods are described including stopping a motor prior to reversing direction as well as methods and systems that implement voltage and/or current protection thresholds.

IPC Classes  ?

• B27C 7/02 - Lathes for hand turning
• H02P 6/30 - Arrangements for controlling the direction of rotation

• H02P 7/03 - Arrangements for regulating or controlling the speed or torque of electric DC motors for controlling the direction of rotation of DC motors
• H02P 29/024 - Detecting a fault condition, e.g. short circuit, locked rotor, open circuit or loss of load
• B23Q 5/16 - Mechanical drives with means for varying the speed ratio infinitely-variable

Abstract

Adjustable work tables and their methods of use are described. A work table tilt-adjustment system includes a tool-free locking mechanism movable between a locking configuration and an unlocked configuration to selectively permit adjustment of the tilt angle of the work table.

• B23D 55/02 - Sawing machines or sawing devices working with strap saw blades, characterised only by constructional features of particular parts of framesSawing machines or sawing devices working with strap saw blades, characterised only by constructional features of particular parts of tables

Abstract

Adjustable fence systems and their methods of use are described. A fence adjustment system includes a drift angle adjustment mechanism configured to adjust the angle of a fence to correct for blade drift.

IPC Classes  ?

• B27B 27/08 - Guide fences or stops for timber in saw mills or sawing machinesMeasuring equipment thereon arranged adjustably, not limited to only one of the groups
• B27B 27/10 - Devices for moving or adjusting the guide fences or stops
• B27B 13/16 - Accessories, e.g. for cooling the saw blade
• B23D 55/04 - Sawing machines or sawing devices working with strap saw blades, characterised only by constructional features of particular parts of devices for feeding or clamping work

Abstract

Adjustable blade guide assemblies and their methods of use are described. An adjustable blade guide assembly includes two lateral blade guides arranged to support opposing sides of a blade and a rear blade guide arranged to support a rear edge of the blade. The blade guides are moveable relative to the blade. The blade guide assembly includes biasing members associated with each blade guide which urge the blade guides in a direction away from the blade. Locking interfaces associated with each blade guide restrict displacement of the blade guides relative to the blade when the locking interfaces are in a locked configuration.
