— FOR IMMEDIATE RELEASE —
Automated Screw Thread Quality Checking using SMAC LAR55 Actuator
The requirement for strict specification and acceptance of all automotive parts and components has greatly
increased in recent years. Screw thread inspection is no exception. The common practice of eddy current
probes, lasers, proximity sensors or vision systems are only partly successful as they only inform you of the
presence of a thread, not if it's correct or within tolerance. The unique low-cost SMAC solution enables you to
automatically check the following screw thread parameters:
• Oversize or undersized threads
• Cross threads
• Thread depth
• No threads
• Mis-located threads
• Thread pitch
• Shallow or blocked hole
The automated thread checking solution from SMAC enables a 100% detailed inspection and verification of all
parts. It also identifies tool wear sooner, and allows SPC data acquisition for process control and quality
systems. All of this translates to higher quality and throughput, lower costs and increased customer
confidence.
An optional Thread Check Graphical User Interface (GUI) is also available. Graphical User Interface, SMAC-
Motion, provides a simple and straightforward way to quickly configure motion parameters of a variety of
SMAC single/dual axis actuators and controllers.
Automotive industry parts and assembly quality standards have moved from sigma level sampling to zero
defect requirements. These more stringent manufacturing results can be achieved through a combination of
containment through 100% inspections (eliminating bad parts) and correction through immediate feedback and
adjustment. Inspection by hand can be reduced or eliminated, parts rejection can virtually be eliminated, and
tool wear can be substantially reduced, all while increasing the pace of production.
SMAC programmable actuators allow 100% detailed inspection and verification for all mission critical parts and
are being used in a variety of automotive applications such as screw thread checking, switch tests, quality
measurement, effort testing, displacement testing and more. SMAC can provide unique inline quality control
solutions that successfully automate inspection procedures.
Automating these processes means:
• 100% inspection
• Increased quality
• SPC data acquisition
• Process control feedback
• Increased throughput
The precision Z-theta motion within the LAR55 actuator provides a convenient pick, orient and place solution to
screw thread checking. SMAC offer a wide variety of LAR55 linear rotary actuators with either direct drive or
gearbox equipped rotary units.

A vacuum-built-in shaft through the rotary motor is available for some models to prevent dust build-up in the
unit. These z-theta actuators can easily be programmed to control force/torque, position and velocity in all
axes at the same time with feedback capability.
Finally, SMAC's unique, patented "Soft-Land" function enables the unit to gently land on a delicate component
with a controlled force to avoid damage of both the component and the actuator.
