Sources Sought for one (1) each Computer Numerical Control (CNC) Lathe

A. Objective:  To find sources that are qualified to meet the supplies/services as listed in section 11B. Note that the specific requirements in section C are subject to change prior to the release of any solicitation.

B. The Government requires one (1) each small-footprint, fully-automated, Computer Numerical Control (CNC) lathe that meets the following minimum specifications:

 Note:  All dimensions, specifications are given in a range format in which the operating characteristics of the machine must fall.

Physical Characteristics

• Work Area – General Requirements

  • Distance Between Centers – Range of 15” to 25”
  • Height of Centers – Range of 4” to 6”
  • Swing Over Bed – Range of 8” to 12”
  • Travel of Cross-Slide – 4” to 8”
  • Travel of Top-Slide - .1” to 1”
  • Top-Slide Rotation - 360°
• Headstock
  • Spindle Through Hole – Range of 1” to 2.5”
  • Rotational Accuracy – No greater than 0.0005” (or angular equivalent)
  • Unsupported Cylindrical Turning @ 100mm – No greater than 0.0005”
• Motor/Power Requirements
  • Voltage – 110V, 50/60Hz is preferred.  208-230V, 50/60Hz will be considered as long as machine can run through a transformer to 110V.
  • Power Consumption – Minimum 1HP, Maximum 3.5HP (Machines in this power range shall fall in our physical footprint requirements, higher HP machines will be too large for our lab space.)
  • Spindle Speed Operating Range –Between 25 and 60,000 rpm.  Speeds shall be infinitely variable within this range.
• Feed Requirements
  • Automatic Feed Rate – Between 0.0020 and 0.0075 inches/revolution.
  • X and Z Axis Path Feed Rate – Between 0.01” and 100 inches per minute.
  • Ball Screw Precision Accuracy - +/- 0.0010” or better.
  • Manual Thread-Cutting Range – Between 7 and 44 TPI (threads per inch).
  • Thread-Cutting Programmability Required

• Tailstock Requirements

  • Spindle Travel Distance – Range of 1.5” to 4”.
  • Lateral Displacement - +/- 0.050” or better

• Controller Requirements

  • Stand-alone PC with touchscreen monitor, or integrated Siemens 808 type controller or equivalent.

• Machine Footprint

  • Width – Between 48” and 84”
  • Depth – Between 24” and 44”
  • Height – Between 18” and 84”
  • Weight – Maximum of 1,500 lbs.

• Additional Characteristics

  • Chuck Size – 3” to 6” Diameter 3-Jaw Chuck
  • Coolant – Through-the-spindle (TTS) is optimal, but conventional coolant capability is acceptable

C. Responses:  All interested parties should notify this office via e-mail within the posted date.  Responses shall include:

I. To what extent each of the specifications can be met.

II.  Include your type of business (i.e. commercial, academia), whether your organization is classified as a large or small business based on the 500 people standard that accompanies NAICS code 333517. If a small business, you must also list any small disadvantaged status you hold [HUB Zone, 8(a), Service Disabled Veteran Owned Small Business (SDVOSB), Women Owned Small Business (WOSB), Economically Disadvantaged Women-Owned Small Business (EDWOSB), etc.].

III. experience/ performance through the description of completed projects.
