COMPANY HISTORY A History of Innovation & Practical Design Advanced Machine & Engineering Co. takes pride in its newly expanded AMROK® Modular Fixturing product line. Throughout our 40 year history of fixture design, we have created families of modular components which have made our product line your premiere source for modular fixturing. Thanks to our dedicated workforce and your feedback, we have found practical solutions to your common workholding problems. At Advanced Machine & Engineering Co., it is our policy to provide products and services that meet the needs and expectations of our customers...

SYSTEM FEATURES Self-Aligning Fixture Elements (S.A.F.E.) The Heart of the AMROK® Workholding System 7

Conventional Clamping Clamping with the AMFLEX® Workholding System S.A.F.E. elements use ball pads to support the workpiece. These ball pads are flexible and align themselves to the contour of the workpiece. The clamping bars also have ball pads, therefore distortion of the part is practically eliminated. When properly applied, the AMROK® system guarantees flexible positioning and stress-free clamping. fThe AMROK® Modular Workholding System has four standard sizes “S.A.F.E.” self-aligning fixture elements. The four sizes differ by the diameter of the ball and the overall size of the units. Ball...

The System Features and Benefits “Horizontal Clamping” using the AMROK® Modular Workholding System. The shape of the workpiece and the machining operations to be performed will determine the style, location and number of components to be used. 1. Set Torque wrench to 32 ft. lbs = 5000 lbs. clamping force per clamp. 2. Total clamping force - 20,000 lbs. 3. Activate center Horizontal Clamp first. 4. Adjust AMF-51067 Ball Elements before activating remaining Horizontal Clamps. 5. Estimated time to assemble fixture = 15 minutes.

SYSTEM FEATURES The System Features & Benefits “Chain Clamping” using the AMROK® Modular Workholding System. The shape of the workpiece and the machining operations to be performed will determine the style, location and number of components to be used.

Fixture System - Vertical Function: Positioning of the workpiece 1st plane: Place workpiece on three supporting units (“A”). 2nd plane: Butt workpiece against two locating points (“B”). 3rd plane: Butt workpiece flush against third locating point (“C”). Function: Clamping of the workpiece with hold down effect The unique construction of the AMROK® Horizontal Clamp produces a downward as well as horizontal clamping force to insure that the workpiece will be held securely. The Horizontal Locators and Clamps have corresponding dual mounting positions located in their faces to allow clamping of thin...

This is a list of some commonly requested grid base sizes. They are only a small sample of the sizes and shapes of grid plates and uprights that can be made. Sizes and shapes not listed can be readily made to your exact specifications. See our AMROK® Tombstone Catalog for other shapes and sizes. All grid bases are available in four styles: • Type “NH” with no holes. • Type “TH” with tapped holes. • Type “BT” with bored and tapped holes. • Type “S.A.F.E.” with precision hardened bushings and hardened-steel threaded inserts. Type “NH”, “TH”, and “BT” grid bases are described on the next page. Type...

Type NH - No Holes This style is commonly used for dedicated fixturing. The holes are machined by the end user. Advanced Machine will machine the holes per specification. If desired, our S.A.F.E. Lock system, Jergens’ “Ball Lock”, or Speed-Loc alignment system are options for mounting dedicated plates on tombstones. Type TH - Tapped Holes Inch and metric threads are offered. Any size and configuration in addition to “grid patterns” are available. 1” and 2” grid patterns are offered as well as 3/4”, 1 1/2” and “offset” grids. Tolerances: Hole to hole non-accumulative = + .005” (for Precision) and...

Machined workpiece quality is directly proportional to the individual tolerances involved. S.A.F.E. Grid Bases are manufactured to the highest precision and quality standards, with our Precision tolerances. NOTE: Please specify Cast Iron or Aluminum. * For Aluminum add 50% to these tolerances. Co-axial positioned bushings and inserts allow both positioning and clamping in every hole. The use of hardened precision bushings assures high wear resistance and replaceability. Glued-in bushings allow replacement without damage to the grid base or hole. If the insert is damaged, it too can usually be...

DETAILS: Custom grid bases are available upon request. Q Specify bushing I.D. used for system. NOTE: Add "A" for aluminum or "C for cast iron at the end of the part number. Note: Geometric tolerances shown are Precision. Please specify Standard or Precision and Cast Iron or Aluminum. Refer to Page 16. Subject to technical modifications.
