b. Manual moment pulse generator.

7. Must have fixed dress in-feed.

8. Must have adjustable dress speed.

9. Must have Electronic control for ease of use.

10. Must have built in electric chuck control.

11. Must have 3 standard T-slots.

12. Must have standard saddle locking device.

13. Must have Cast iron/Aluminum way covers, due to the type of coolant being used, will degrade and destroy rubber bellows.

14. Must have max distance from table to underside of 14" wheel of 20.60" spindle.

15. Work light suitable for coolant use.

16. H-shaped guideways with 3 tapered gibs provide the strength necessary for heavy duty grinding and the precision for extra fine grinding or equivalent.

17. Automatic grinding capabilities must include

a. Traverse Grinding

b. Plunge grinding with infeed

c. Rough and fine grinding cycles

d. Preset spark out passes.

18. This system shall include the following accessories with power supply and controls:

a. coolant pump and tank

b. vacuum dust collector

c. magnetic chuck

19. Overall power requirement of 480V 3 phase

20. Motor size should be no less than 5HP

21. Hydraulic pump should be no less than 2HP

22. Size of machine shall not exceed 107 x 75 x 90" due to space requirements and safe operation.

23. Must not exceed 5,500 lbs.

24. Remove old equipment and provide credit for fair trade in value of following:

a. Grinder 12-24

b. Wet Grinder, Chevalier Grinder 1224

c. Serial# P3956002

d. 480V

25. Provide manufacturer suggested preventative maintenance schedule and any related preventative maintenance for the period of at least one year.

2.2 Software:

1. None required

2.3 Delivery and training:

1. The customer shall receive all components within 180 days after contract award.

2. This item intentionally left blank.

3. Contractor shall provide all necessary training for hardware to a minimum of two personnel.

3.0 WARRANTY:

1. Free from defects in material and workmanship under normal and proper use in accordance with the maintenance manual, for the period of time of at least one year after receipt.

4.0 INSPECTION AND ACCEPTANCE:

This section intentionally left blank

5.0 DELIVERY INSTRUCTIONS:

This section intentionally left blank.

6.0 INVOICE AND PAYMENT:

The contractor shall be paid upon submission of a properly prepared invoice and after final inspection and acceptance has been made. A proper invoice shall cite the contractor’s name and address, invoice number, invoice date, order number, contract line item number (CLIN), description of the supplies or service, unit of issue, unit price and extended price, terms of any prompt payment discount offered, and who to notify in the event the invoice is defective. The invoice shall be submitted to:

The contractor shall submit invoice in wide area work flow (WAWF) as shown in this order schedule.

7.0 DELIVERY PROCEDURES COMMERCIAL VEHICLES

All vehicles larger than a large pick-up truck are required to be inspected by the Wright- Patterson Air Force Base Commercial Vehicle Delivery Gate (CVDG) prior to entering the installation. Vehicles to be inspected include, but are not limited to, the following:

1. Step van/panel truck

2. Tractor/trailer, box and flatbed containing cargo

3. Tanker trucks

4. Box trucks

5. Tour buses

6. Garbage/recycled waste trucks

7. Concrete trucks/mixers, dump trucks

8. Cranes, recreational vehicles, petroleum tanker

This inspection will be conducted at Gate 16A located off State Route 444.

The following are exemptions to vehicles utilizing the CVDG:

1. If the vehicle has the product inside (concrete and asphalt trucks) and timely delivery is necessary due to product deterioration it does not need to enter the CVDG. To bypass the CVDG, the contractor shall submit a list containing drivers’ names, social security numbers and the state in which the driver's license is held for those drivers who will be entering the base. This shall be accomplished 24 hours prior to requested entry time. If entry is requested on Monday, this list shall be submitted by Friday at 1630 hours. All lists shall be submitted to the 88th ABW/CE Directorate contract inspector. The only gates that may be used under this exemption shall be 15A, 26A, 38A, and gate 1B. If the driver's name is not on the list, he/she will not be allowed access to the installation through these gates and the base will not assume liability for denied access.

2. If a delivery vehicle shall exit, and then re-enter the base to complete its route, the vehicle shall be resealed upon exiting the base. After initially passing through the commercial vehicle delivery gate, trucks shall be resealed at Gates 15A, 38A and 22B. The resealing of the trucks will allow them to continue to any other area of the installation (Areas A, B, or Kittyhawk) without reprocessing through the CVDG. To receive resealing assistance, the drivers shall physically stop at one of the three authorized gates and request the installation entry controller to reseal their truck and provide the next location of their delivery. The controller will reseal the truck and give the delivery driver a pre-clearance form. The driver shall present the pre-clearance form to the entry controller at the next point of installation entry. This reentry can be through any base gate.

3. Vehicles may be subject to an inspection at any of installation entry control points during a directed random antiterrorism measure (RAM.) Any commercial vehicle, regardless of size, can be directed to the CVDG at the discretion of the installation entry controller.
