Design & Build Services

Technical data:

Tailstock manually adjustable in x-axis from 50" - 180".

• Swivel plate manually adjustable 6° with (7) fixed angular positions using a hardened and ground shot pin in hardened and ground bushings. Fixed positions at: 0°, ±2.5473°, ±2.8022° and ±5.0997 

Precision 15HP Servo drive either by a worm or preloaded hardened gear mechanism whichever will guarantee best accurate service life. Maximum speed 3 RPM.

• A 5: diameter hole, 24" deep in the headstock and a 5" dia. hole through the tailstock. 
• Tailstock manually adjusted vertically by .30" Fine adjustment to .0003" using dial indicators. 

Face plates in head and tailstock have provisions to either mount customer 3 Jaw Chucks or knife bar fixture supports.

• Maximum weight of above fixture not to exceed 15 tons. 

Positioning Accuracy:

• Swivel Plate ±10 arc sec. 
• Headstock: ±10 arc sec. (for rolls only). 

Higher accuracy can be achieved but will be more expensive.

• Repeatability: ±2 sec. 

Maximum weight of knife bar fixture including parts:

• 12,000 lbs on max off center of 24". 
• Hydraulic Pressure at approx. 1000 PSI and the electric power supply will come from your machine. 

With AME you get advanced problem-solving expertise, and the proof is in our highly specialized systems. For example, AME is one of the few design-build companies in the world to offer custom milling heads for machining at odd angles in hard-to-reach locations. These built-to-order spindle attachments, an AME specialty, are precision engineered to fit your machine, expanding its original functionality while solving a specific problem. Numerous types of milling heads are available: straight, right-angle, swivel, gimbal and nutator.

This customer had two very large 5-axis milling machines of the same design which needed upgrades:

• Backlash reduction B & C -axis gear train 
• Improve machine performance (spindle drive) 
• Spindle re-design to allow for power drawbar 

The rebuild of these two machines proceeded in the following phases:
 
 1. Disassembly and inspection of machine #1

• Inspection and measuring of components; status report 
• Reassembly - machine back in production 

2. Reverse engineering

• Re-calculation and design 
• Creating manufacturing drawings 
• Manufacturing parts for both machines; second gear set unground 
• Inspection certification 
• Purchasing parts for both machines 
• Documentation and manual update 

3. Rebuild of machine #1

• Disassembly and reassembly with new parts 
• Final testing - machine back in production 

4. Rebuild of machine #2

• Disassembly and inspection of components; status report 
• Finish grinding of second gear set 
• Reassembly with new parts - machine back in production 
• Documentation and manual update
