TESTINGEfficiency Measurement - Helix Engineering has designed test machines to measure and validate screw assembly efficiency.
Torque Measurement - Preloaded lead screw assemblies are evaluated to determine compliance with engineering specifications utilizing a Dynamic Torque Testing Machine.
FUNCTIONAL TESTINGHelix test systems and engineered testing processes perform analysis, verification, and solidification of life, durability, and performance. The functional testing defines operating limits in specifications and helps set defined targets in Product Launch Process and Assurance Plans.
The engineered testing provides predictive tools, generates data for prognostics, and validates performance wear models. Life tests help determine performance in multiple operating conditions as well. Helix offers proof testing for customers developing new systems and actuators to help accelerate product release dates.Helix lead screws are used in multi-channel pipetting applications
When you select Helix Linear Technologies as a supplier, you can be assured that your product will be designed and tested to rigorous product planning. Pre-design activity includes understanding of customer requirements applied to predictive models, engineering calculations and linear modeling through prototype development, stereo-lithography samples of form, fit, and function that verify design criteria.
VALIDATION AND VERIFICATIONThrough years of rigorous development, Helix has proven its designs and manufacturing processes against the most stringent standards and specifications. Design and process verification and validation tools are employed throughout the product life cycle.
CERTIFICATIONSHelix serves many customers in the Aerospace and Medical device markets and has complied with common Quality System Requirements. ITARHelix is registered with the Department of State For International Traffic In Arms Compliance.
INSPECTION CAPABILITYLaser Lead Measurement - Precise lead error gauging is uti-lized to validate processes to conform to Helix internal specifica-tions and customer requirements.
Roundness Measurement - Critical to quality, characteristics such as roundness are monitored throughout the screw manufacturing process.
Contour Readers - Prior to the start of any production run, thread form geometry is precisely measured to stringent engineering specifications.
Metallurgical Lab - The metallurgical lab is capable of determining material composition from raw materials to final product. A micro hardness and case depth inspection is a routine check that validates the heat treat processes when required.

BALL SCREW THREAD FORM TERMS INTRODUCTION - Ball screws offer an efficient means of converting rotary motion to linear motion. A ball screw is an improvement over an acme screw just as an antifriction ball bearing is an improvement over a plain bushing. Ball screw as-semblies have a number of bearing balls that transfer the load between the nut and screw. The thread form in which the bear-ing balls ride is an ogival shape formed from two arcs of the same radius with offset centers. This form is also referred to as a gothic arch. See below.
BALL CIRCLE DIAMETER - The diameter of the circle generat-ed by the center of the bearing balls when in contact with the screw and nut.
ROOT DIAMETER - The diameter of the screw measured at the bottom of the thread. This is the diameter used for column strength, critical speed calculations and end machining consid-erations.
PITCH - The axial distance between threads. Pitch is equal to the lead in a single start screw.
LEAD - The axial distance the nut advances in one revolution of the screw. The lead is equal to the pitch times the number of starts.
PITCH × STARTS = LEAD
SCREW STARTS - The number of independent threads on the screw shaft; typically one, two or four.
LEAD ACCURACY - Lead accuracy is the difference between the actual distance traveled versus the theoretical distance traveled based on lead.
BEARING BALL CIRCUIT - The closed path that the bearing balls follow through the ball nut. Ball nuts have one or more circuits. RETURN GUIDE - Component that allows the bearing ball to be picked up and returned to the beginning or end of the circuit.
LOAD CARRYING BALLS - The bearing balls in contact with ball nut and ball screw sharing the load.
LAND DIAMETER - The outside diameter of the screw. This diameter is less than the ball circle diameter.
MATERIALSStainless Steel: - 1.3505 (100Cr6) - 1.12 (Cf53)
On Request: - Corrosion-resistant steel 1.4034 (X46Cr13) - Other materials
On Request: -Coating for corrosion protection
Please Note: The use of corrosion-resistant steel results in lower load ratings Details on request.

BALL SCREWS CHARACTERISTICS• High load ratings, and are therefore suitable for high static and dynamic loads• Excellent efficiency (µ > 0.9), therefore: • Low drive power required• Low energy consumption• Low self-heating• Low-friction operation No stick-slip effect• High accuracy for positioning and repetition• High reliability and long service life with minimum need for maintenance• Wipers available on request
LEAD SCREWS CHARACTERISTICS• Small to medium load ratings, therefore suitable for low to medium loads• Very high travelling speeds, thanks to over-square pitches (p ≤ 6 × d)• High efficiency (µ~0.5...0.8), thanks to high surface quality of the steel leadscrews and nuts made of high- performance plastics• Weight optimization possible based on aluminum screws• Performance optimization sometimes possible based on coating• High reliability and long service life with marginal need for maintenance
