Gleason 400GH 'recontrol' & 'recertification' program.
The machine will be equipped with a FANUC 0iF Plus CNC control featuring color CRT, conversational English dialogue, and automatic setup across six controlled axes, with all parameters available in inch or metric. It also features the renowned Machine Tool Builders conversational programming software as described further - below.
The machine is currently on the floor at Machine Tool Builders in Machesney Park, IL. It is expected to be under power and available for demonstration—and ultimately shipment to a client—near June, 2026.
This 400 mm-class CNC hobber carries forward the Gleason legacy of rigid construction and forward-looking engineering. High-speed capability, robust castings, and modern design principles give it the backbone to fully exploit today’s—and tomorrow’s—cutting tool technology. The PHOENIX 400GH keeps its footprint compact without compromising rigidity, accuracy, or serviceability, and its use of standardized, globally supported components helps ensure quick delivery, lower maintenance, and minimal spare-parts burden.
Built-in thermal stability and Gleason’s mature CNC software platform deliver excellent accuracy and repeatability while keeping operating costs in check. The machine supports both wet and dry hobbing and handles high-speed steel or carbide tooling with ease.
Gleason’s CNC hobbers have long been benchmarks in the industry; the 400GH builds on that lineage. It’s engineered for straight spur and helical gears, pinions, splines, worm gears, and similar profiles up to 400/450 mm (15.75/17.72 in) diameter, 525 mm (20.67 in) face width, and 2.5 DP capability.
Gleason PHOENIX 400GH — Controls Retrofit Program Description & Consolidated Specification Sheet:
1 All work will be done at MTB facility in Machesney Park, IL.
2 The machine will be fully re-controlled with a new CNC, new drives and servo motors, and a new electrical cabinet.
MECHANICAL:
3 Engineer as required then manufacture and supply all motor adaptation flanges, couplings and pulleys.
4 Remove old servo motors and install new servo motors.
5 MTB will check and report on all axes positioning and performance.
6 No mechanical repairs will be undertaken unless required to complete the recontrol. Should MTB identify any mechanical issues during the recontrol we will bring them to your attention and a course of action can be determined at that time.
HYDRAULIC:
7 MTB will interface the new CNC/PLC with the existing hydraulic system. However no hydraulic system modifications will be undertaken unless required to complete the recontrol.
LUBRICATION:
8 MTB will interface the new CNC/PLC with the existing lubrication system. However, no lubrication system modifications will be undertaken unless required to complete the recontrol.
COOLANT:
9 MTB will interface the new CNC/PLC with the existing coolant system. However, no coolant system modifications will be undertaken unless required to complete the recontrol.
CHIP EXTRACTION:
10 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.
ELECTRICAL:
11 A new operator’s panel.
12 All new secondary encoder cabling will be run for encoders we need to replace.
13 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.
14 MTB will provide all wire, tags, conduit, flex and other miscellaneous equipment required to complete the installation per NFPA codes.
15 All electrical prints and parts lists will be drawn with AutoCAD Electrical.
15 All new servo motor power and feedback cables will run.
16 Cabinet will remain in the current location
17 Power requirements will be 480VAC; 60Hz. Power figures will be available after the electrical engineering is completed.
CONTROLS:
18 Fanuc 0iF Plus CNC
19 Fanuc 10.4” Color LCD touch screen display unit
20 Fanuc drives and motors
21 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.
DOCUMENTATION:
22 Two (2) copies of the wiring diagrams on 11x17 paper. Per machine.
23 Two (2) copies of the MTB operators Instruction manuals. Per machine.
24 Two (2) copies of spare parts and service manuals for equipment supplied by MTB. Per machine.
25 Two (2) copies of the PLC logic interface program and backup USB. Per machine.

27 One (1) copy of the Fanuc CD for the CNC and drives.
INSTALLATION & RUNOFF:
28 Customer to provide assistance with installing of the recontrol package with but not limited to cranes, forklift, ladders, etc.
TRAINING:
29 MTB will supply training at additional charge based upon customer specifications as part of sale.
BUILD SPECIFICATIONS:
30 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.
