- Description
- Amendment 0002 Questions and Answers Optional Equipment List: Those components are not required, but encouraged as the best value analysis, and no proposal will be eliminated because they do not offer one or more of them. Q - Do you have a print of the Valve Plug? A - Yes, the print is being uploaded Q. - In the below attachment, it states the machine should be shipped to Denver, Colorado. It is our understanding the machine is to be shipped to the Lakehurst facility in New Jersey. A - No it will be shipped to the project site. Hwy 547 Lakehurst, NJ 08733 Q - Can the dead line for submittal be extended from Friday July 15th to Friday July 29thThis would give us time to review your responses and get with our builder contacts, who as we do travel quite extensively worldwide. Thus allowing proper evaluation on question responses and provide adequate time for pricing etc to be quoted and properly evaluated. And receive quotes for contractors for concrete and electrical work required for this solicitation. A - Yes, deadline has been extended Q - Solicitation SF1449 has a delivery to Denver CO.? A - Already been answered above. Q - What is this referring toLine item 0001 and 0002? A. - it is a breakout of the proposal. You can submit your proposal in the offeros formal and also breakoutinto the two CLINS. Q - Is this a requirement to ship machine to Denver CO for testing A - No. The equipment is to be shipped to Lakehurst, NJ Q - Does Machine have to be TAA complaint? A - yes. Q - For a factory delivery machine based on requirements contained in solicitation and based on response to these questions. Delivery may be longer, can the delivery date of 12/30/2011 be extended? A -We are not specifying a delivery date, and will accept the typical production and delivery lead time. Q - What is the weight of the final part? A - roughly 1400 lbs. Q - What is the material of the parts being cut? A - 410 stainless steel Q - Can we get a print of part? I believe the original solicitation that was sent out last year had one attached. This would be good to have to look at clearances. A - yes, it is attached. Q - Just to clarify. a) Do we have to provide tooling to hold the part? yes b) Or have you engineered how you will be holding? no c) Or are we required to engineer part holding similar to old lathe setup? no Elaborate please. A - Based on the print of the part, please provide a work holding solution that will secure the part in your machine. Q - 2.5.1 Foundation -- Has the floor at the area of the installation be core drilled to checked for accuracy of the 6"-8" deep concrete statement? no We will quote foundation of course of course but this leads to other questions. a) Has soiled be checked for contamination? There is no contamination in the soil that we are aware of. b) Will a separate PO be issued to deal with contaminated soil if found? yes c) Repair of epoxy flooring around machine * 1. Will we be responsible for this repair? Yes, vendor will be responsible. * 2. If so, please provide name of vendor who did the original flooring so a quote to repair such can be obtained. West Bay Construction * 3. Will you be scanning the existing foundation to assure that there are no additional utilities beneath which would impact our contractors? yes A - Q - What is the door dimension that we will be going thru when machine arrives? A - The machine can be delivered through either the front or back roll doors. The dimensions are: front door- 20' wide x 24' 11" high Rear door- 18' 6" wide x 18' 9" high. Q - What is dock level heightIs it ground level? A - ground level Q - 2.6 Training - how many days of training for machine operation and maintenance should be quotedDo you want this onsite or can your personnel travel to training center? a) Please elaborate as to any additional training requirements that would be needed beyond the standard 3 -5 operator training A - 3-5 days of operator training, 2-3 days of maintenance personnel training. Q - 3.8 Hydraulic Chuck a) Most manual / CNC type flat bed machines have a manual type chuck systemWhy the Hydraulic Chuck requirement? b) Can a Pneumatic / Air one be provided in place of Hydraulic? A hydraulic chuck is preferred. c) How clean is the factory air? Does air pressure fluctuate? Air pressure does not fluctuate, air will be cleaned with filters and moisture separators before the machine. d) Do you have a preferred chuck manufacturer that you would like us to quote? no e) 3 jaw or 4 jaw chuck? Either, but the chuck should be an adjustable center type f) If we go with a Hydraulic chuck RPM we need to go to an 8.7 spindle bore. Our RPM will drop to 700 RPM is this sufficient? The requirement was for 1000 RPM spindle speed. A lower speed would be considered, but as a lower priority A - Q - 3.10 Overhead loading a) This leads into question on Chip guarding also and clearances. Please provide largest work piece print. A - print is attached. Q - 3.11 Chip Guarding - fully enclosed is not the standard on most flat bed lathes? Normally a 2-3 door sliding door is the standard configuration. Is this sufficientBecause a fully enclosed machine would be a special. Please elaborate. Additional quoting required for a "CUSTOM" solution may be required. a) Providing a fully enclosed lathe would severely limit access to the tailstock. Is this understood? A - This is understood. A fully enclosed chip guard is preferred, a partial chip guard may be considered, but at a lower priority. Q - 3.14 Optional equipment list - * Tool eye / Pre setter * Live C axis live tooling turret a) With a flat bed lathe configuration this would cause interference potential with the part we saw that was to be machined. Please provide print per question 3. b) With flat bed configuration, do you want this to be a removable turret design? no c) Please elaborate on your expectations of this option. The optional C axis would be used for other work pieces or other operations on the valve plug. * Conversational Control - since no control type is specified. a) Is a non conversational control ok? no b) Is FANUC ok? yes c) Siemens and/or other options offer better conversational controllers, would these also be ok to propose? yes d) Elaborate on your expectations of a conversational control. What processes do you want the controller to do for you? Basic programming of simple part geometries. e) Please elaborate as to any additional training requirements that would be needed beyond the standard 3 -5 operator training 2-3 days of maintenance personnel training. * High Pressure Coolant a) What pressure is required? Vendor may propose what pressure they feel is appropriate for the application. b) Is there a preferred high pressure system you would like us to quote? no c) High pressure coolant can be controlled manually or thru "M codes" which is preferred method? Both manual and M codes for turning coolant on and off, no preference for pressure adjustment. * Steady rest a) What size diameter wise on steady rest is desirable? Maximum diameter no larger than the chuck diameter. b) Additionally a steady rest would pose and interference potential with the part to be machined? So therefore a drawing of part as requested in item 3 would be required. c) This could lead to a flat bed design machine with a double rail system requirement. Please advise is this a double rail system what you are asking for? This would be considered. * Follow rest a) What size diameter wise on follower rest is desirable? Maximum diameter no larger than the chuck. b) Again this could lead to interference issues with part to be machined? * Heavy Duty boring attachment a) What is your definition of "Heavy Duty" This can be turret mounted or on cross slide at times or on center in tailstock? Vendor may propose whatever method they feel will work with their machine. b) What will be the deepest bore requirement and finish required? We do not have an immediate requirement for this type of work, so no depth or finish requirement is available. * Double Turret - this can mean a variety of types? a) Please elaborate. The intent was to use one turret for each side of the plug bell, so that the part could be machined in one set-up. * Counter centrifugal chuck a) Is this due to the weight of part? b) Does this mean a rear mounted chuck? No. Please elaborate.
