Reverse Engineering

• Fast, ultra-accurate results, reducing your time to market
  
• Complete measurement data of the entire surface of your object, verifying that the as-built part matches your CAD model
  
• True CAD models for FEA testing of actual geometry to correct problems before parts go into production
  
• CAD models to validate tooling, even when no current models exist
  
• Profile data of the whole part so assemblies can be digitally put together, revealing inaccuracies and interferences

Tool path creation Polygonal / STL meshes Composite blends NURBS curves NURBS surfaces Tooling verification And many more

• Accurate- laser tracking has an accuracy of 15 microns over a distance of 20’
  
• Extremely portable- laser tracking gives the ability to measure and inspect objects on-site, in-process or where it’s most efficient and cost-effective for you
  
• Laser tracking uses an ultra-precise laser beam to measure objects (0-72 meter range)
  
• Can be used in most any environment
  
• Due to the tracker's spherical measuring volume, dimensional information is able to be evaluated from almost any perspective
  
• High-Precision- the coordination of both vertical and horizontal encoders allows for angles for very accurate measuring capabilities using the laser tracker
  
• Set milling machines and align machine tools with accuracy
  
• Check parts on machine beds
  

HS&S’ experienced metrologists use the latest digitizing and software technologies available for both contact and non-contact measurement to perform dimensional inspection for your company.

The HS&S's Northern California facility is covered by ISO/IEC 17025. This standard is more stringent than the ISO-9000 standard, or the QS-9000 standard, and is the correct standard for a testing laboratory. Also soon to be ITAR Registered for Military product manufacturers

Through the scanning of a physical part, 3D scan data is compared directly with the nominal CAD model to verify that the finished part or tooling conforms to the original design intent. Alternately, two sets of point cloud scan data can be compared with each other during the manufacturing process to assure parts stay in spec.

Traditional touch-probe contact measurement is usually used when certain (prismatic) features or locations of a part need to be dimensionally inspected to a tight tolerance. It can be performed with a manual CMM/PCMM, or automatically with a programmable CMM.

Dimensional Inspection Services Include:

• Physical part to CAD model comparison (product verification / tooling verification)
  
• PPAP (Production Part Approval Process) - Production part approval prior to the first production shipment of product in the following situations to identify changes that might affect the direct customer or ultimate purchaser
  
• Process Capability Studies - Collect, compile, and analyze data utilizing best practices
  
• Gage R&R (Repeatability & Reproducibility) - The HS&S electronic data processing center and our high speed computerized CMMs can help you meet your R&R and Statistical Process Control requirements in a useful, timely way
  
• Impartial Evaluation - Third party non-biased assessment of product conformance and specifications. HS&S also provides expert witness testimony in product liability
  
• 3D Surface roughness/surface evaluation non-contact optical inspection- state-of-the-art equipment and expert understanding of 3D surface metrology help you solve your problems related to surface roughness, wear, texture, finish, flatness and more
  

Machine Tool Calibration

With everyday usage, and in some cases seasonal changes, your machine tool will lose its accuracy. This has a direct impact on the quality of your product and the efficiency of your processes.
A periodic ( usually once a year ) calibration will help assure your machine performs within specifications and minimize scrap and rework of product due to poor machining accuracy.

What Are The Benefits Of Laser Calibration?

•  Increase Machine Uptime and Productivity
  
•  Minimize Scrap and Improve Part Accuracy
  
•  Increased Positioning Accuracy
  
•  Develop Predictive Maintenance programs on machine wear patterns
  
•  Detect mechanical soundness after a crash
  
•  Better circular interpolation
  
•  Match the accurate machines with the closest tolerance work
  

Laser Calibration and BallBar Analysis

Laser calibration should be performed after any major mechanical work is done to a machine's axis, such as replacement of ballscrews or thrust bearings. Our Renishaw XL-80 laser measures positioning error and allows our technicians to set compensation in the control and determine if repairs are needed and can be done without tearing down most existing setups.

Ballbar analysis is one of the best tools to determine your machine tool's mechanical and servo performance and allows comparisons with other machines in your facility. It allows error sources such as backlash, reversal spikes, lateral play, squareness, straightness, scaling mismatch, and servo tuning discrepancies to be pinpointed, quantified, and reduced or eliminated, resulting in better accuracy in circular interpolation. Ballbar analysis can be performed in all planes of motion (XY, YZ, and XZ) if required.

Hardinge Rebuilding

HS&S has performed many forms of machine building, rebuilding, machine design and machine automation over the years but since 1970 they positioned themselves as Hardinge HLV-H and Chucker Experts. The president of Hardinge visited our rebuild facility in 1984 and noticed that we painted the collet closer and motor castings black instead of grey like the rest of the machine. A year or two later Hardinge used the black wrinkled finish as aesthetic contrast also. If you have a Hardinge that no longer holds tolerance or just need an overhaul, send us an email and a picture and we can make it like new or trade it in for a rebuild machine out of our stock.

Rebuild features include:

•   Complete dismantle for testing/evaluation and prep for paint
  
•  Dovetail bedplate precision reground (replaced if needed)
  
•  Top of carriage is also ground for aesthetics purposed
  
•  New Bushing in the Vari-disc assembly
  
•  Collet seat is re-ground
  
•  New Long feed hand wheel gear shaft and bushings
  
•  new bearing on collet closer and tailstock
  
•  Tailstock spindle replaced
