18 No other coolant system repairs will be undertaken unless required to complete the recontrol. Should MTB identify any coolant issues during the recontrol we will bring them to your attention and a course of action can be determined at that time.

Chip Extraction
19 MTB will interface the new CNC/PLC with the existing chip extraction system. However no chip extraction system modifications will be undertaken unless required to complete the recontrol.
20 No chip extraction/filtration repairs will be undertaken unless required to complete the recontrol. Should MTB identify any issues during the recontrol we will bring them to your attention and a course of action can be determined at that time.

Electrical
21 A new electrical cabinet will be installed with all new equipment inside. IEC devices along with circuit breakers will be used wherever possible.
22 A new operator’s station will be installed where the current one is. It will include the CRT, Keyboard and Machine operation panel mounted inside.
23 Machine wiring which is not directly a part of the recontrol or retrofit will be reused, and connected via terminal strips within the new panel.
24 MTB will provide all wire, tags, conduit, flex and other miscellaneous equipment required to complete the installation per NFPA codes.
25 All electrical prints and parts lists will be drawn with AutoCAD Electrical.
26 All new servo motor power and feedback cables will be run for only the replaced servos on the machine.
27 All new secondary encoder cabling will be run for only the replaced servos on the machine.
28 New cabling to the operator’s station or pendant will be run.
29 Unless otherwise stated all axes will be measured from absolute encoders within the servo motors.
30 X axis (radial) will use a new Heidenhain absolute scale (No referencing required upon power up).
31 Reuse any electrical cabinets, duct way and junction boxes that are practical to reuse, unusable ones will be replaced with new.
32 Power requirements will be 460VAC, 60Hz. Power figures will be available after the electrical engineering is completed.

Controls
33 Fanuc 0iF+ CNC with 10.4" horizontally arranged color display and machine operator's panel.
34 Fanuc Alpha HVi digital servo drives and motors.
35 Fanuc Alpha HVi digital spindle drive(s) and motor(s).
36 ATTENTION - If your plant power system is not a wye scheme with grounded center point, you will require an isolation transformer for these new drives.

Shaping Software
37 Conversational based platform within the CNC; CNC based using Macro executor.

39 Up to five cuts per cycle.
40 Spiral or Plunge infeed cycle.
41 Programmable rotary dwell.
42 Digressive infeed feedrate.
43 Inch / Metric switchable.
44 Spiral out of cut.
45 M and G code programming is allowed with conversational programming present.
46 Multiple program storage and retrieval.
47 Quick recut cycle.
48 Auxiliary function selection (tailstock/clamping seq.).
49 Automatic cutter indexing (Requires independent cutter 'B' and worktable 'C' axes).

Installation and Run Off
60 Installation, runoff and training at your facility.

Training
61 MTB will supply 2 days of operator training at the completion of the installation.
62 MTB will supply 1 day of maintenance training at the completion of the installation.

Build Specifications
63 Electrical, mechanical, hydraulic, pneumatic and safety systems will be installed in accordance with all applicable customer specifications, and ISO, IEEE, ANSI, DIN and NFPA standards.

Customer Responsibilities
1) Supply electrical, mechanical, hydraulic and lubrication schematics plus any software printouts and operators manuals for the existing machine.
2) Supply test parts, fixtures and cutters for the machine testing at completion of the recontrol.
3) Machine should be cleaned, and degreased prior to the recontrol startup.

Machine Runoff
Machine runoff will be as follows. Prior to the recontrol beginning a sample part will be shaped. The part will be inspected for all geometries. After the recontrol is completed the same sample part will be shaped again, using the same cutter and tooling. The geometry of the part shaped after the recontrol will be compared to the part shaped prior to the recontrol. The recontrol will be considered acceptable if the part shaped after the recontrol is equal or better in quality to the part shaped before the recontrol, and provided that the machine performs all of the same functions without issues related to the recontrol.

Shipping
The purchaser shall be responsible for all fees related to transportation and rigging of the recontrol equipment from MTB’s facility to yours.

Payment Terms
See "Standard Terms and Conditions of Sale".

Warranty
One year on the recontrol; see "Standard Terms and Conditions of Sale" for details.

Delivery
Approximately 4 months after receipt of a PO.
