Minimum Requirements For

Manual surface grinder

1.0 GENERAL OVERVIEW:

AFIT requires grinding different types of material using a handfeed surface grinder holding tolerances of .0005”. In order to meet the demands of student research, the surface grinder must be a rigid machine. Rugged base and column construction supplies the rigidity and stability needed for both coarse and extra fine grinding requirements. Extended saddle longitudinal ways reduce overhang to provide long machine life and peak accuracy. Double-V table ways allow for heavier table loads to ensure true tracking for improved accuracy. This is a replacement of an older model which is worn out and does not meet the safety requirements of today’s machines.

2.0 MINIMUM REQUIREMENTS:

2.1 Shall meet the following basic requirements:

1. A minimum of 6.2 x 18.9” working area

2. Grinding wheel adapter

3. Automatic lubrication

4. A coolant system with splash guard is needed

5. Fine pole electromagnetic chuck with controller capable of automatic release cycle

6. Magnetic Chuck Size (WxL) 6 x 18”

7. Digital scale for Two Axes

8. This system shall include the following accessories with Power supply and controls.

a. coolant pump and tank

b. vacuum dust collector

c. magnetic chuck

9. Overall power requirement of 480V 3 phase

10. Size cannot exceed (L x W x H) 77 x 56 x 68”, due to space restrictions and safe operation

11. Cannot exceed 2,100 lbs.

12. Maximum travel, Longitudinal 20.87”, cross 8.27”

13. Maximum distance wheel to table 14.27”

14. Minimum 1.5 hp grinding wheel spindle

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

a. Grinder 6-18

b. Chevalier Grinder 6-18

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.
