Summary on Wuxi JACK Steel Structure H Beam End Face Milling Machine
A. Working Principle of Steel Structure End Face Milling Machine:
1. Usage: Steel Structure / Pipe End Face Milling Machine is used for performing end face milling on various structures and sizes of metal parts, so that these metal parts can be processed further in subsequent welding/ assembly/ installation, etc.;
2. Classification on Steel Structure H Beam End Face Milling Machine:
1) Conventional (Relay Control): From DX08xx light duty, to DX15xx standard models, to DX40xx (Example: DX4080) ~ DX60xx (Example: DX6080) Large Steel Structure End Face Milling Machine;
2) CNC H Beam End Face Milling Machine: From CNC-DX12xx to CNC-DX35xx;
3. Working Principle of Steel Structure H Beam End Face Milling Machine:
1) Core Unit: Conventional and CNC End Facing Machine utilizes high speed revolution of milling head to perform end facing job on workpieces;
2) The milling head equipped in End Face Milling Machine is same as equipped in Machining Milling Machine;
3) Working speed can be adjusted continuously, easily and intuitively in all the models of Steel Structure End Face Milling Machine;
4) The 7.5kW milling head in Wuxi JACK H Beam End Face Milling Machine: (Fig.3)
4. Milling Head Movement in Conventional and CNC End Face Milling Machine:
1) X Axis: By means of upright column moving along horizontal base bed;
2) Y Axis: By means of milling head carriage, moving up and down, along upright column;
3) Z Axis: Milling head tilts 0°~ 45°. In this way, slant face working parts can also be end faced. This is unique capability of Wuxi JACK H Beam End Face Milling Machine.
B. Main Units in Conventional and CNC H Beam End Face Milling Machine:
1. Mechanical Main Frame of H Beam End Facing Machine:
Shown in the below photo, this includes:
1) Stationary horizontal base bed, fixed into workshop ground;
2) Horizontal moving upright column, assembled with horizontal base bed in perpendicular;

4. Electric Control System in Conventional and CNC H Beam End Face Milling Machine: (Fig.6)
1) In conventional models of H Beam End Face Milling Machine, working logic is managed with A.C. relays; X/Y 2 axis end facing working speeds are controlled with A.C. inverters, and displayed on digital meter of operating pendant in real time;
2) In CNC End Face Milling Machine, all the above jobs are managed with CNC controller:

C. Factors Affecting Quality of Steel Structure H Beam End Facing Machine:
1. Definition on “Good Quality” in Steel Structure H Beam End Face Milling Machine:
1) Delivering finished workpieces with qualified precision and roughness, with high productivity;
2) Stable and controllable performance;
3) Applicable on broad range of workpieces;
4) User friendly operation;
2. Quality Assurance in Wuxi JACK Steel Structure End Face Milling Machine:
1) Design and validation confirming to APQP system;
2) IQA: Incoming quality control on outsourced components;
3) Process Quality: Quality gate and checking list; Standard operation instruction;
4) Customer Service: ICA within 4 hours; 8D report within 1 week;
5) Continuous Improvement based on feedback from customers, and years of experience accumulation.
D. Several Ways to Get High Quality Relay Control and CNC End Face Milling Machine:
1. Superior Milling Head in Wuxi JACK Steel Structure H Beam End Face Milling Machine:
1) This unit plays key role on determining machine performance;
2) Wuxi JACK selects 7.5kW milling head in all the conventional models H Beam End Face Milling Machine. It has convenient way of spindle revolution regulation, 6 grades;
3) 9.3kW or 11kW in DX4080 ~ DX6080 special size Large Steel Structure End Face Milling Machine;
4) Comparatively, other companies select 5.5kW milling head, which has lower productivity, time consuming spindle speed regulation or even no speed change available;
2. Strong and High Strength Upright Column in Steel Structure H Beam End Facing Machine:
1) Significance: Strength and rigidity of mechanical body, especially the upright column, influence directly machine performance;
2) For Large Steel Structure End Face Milling Machine with max. vertical stroke above 3500mm, insufficient strength of upright column (Too soft and flabby) will cause issues of column swing: Milling head shuns away from workpiece;
3) In Wuxi JACK H Beam End Face Milling Machine, cross section size and structure of the upright column are carefully calculated and validated, guaranteeing sufficient margin of firmness;
4) Hanging upright column of Wuxi JACK DX6080 Large Steel Structure End Face Milling Machine: (Fig.7)
3. Workpiece Clamp Unit in Steel Structure End Face Milling Machine:
This is discussed in detail in blog:” Find the Most Applicative Workpiece Fixtures in End Face Milling Machine”;
4. Top Grade Quality Heavy duty Precise Linear Guiderails in Wuxi JACK H Beam End Face Milling Machine:
1) Shown in the below photo, milling head movement along upright column and horizontal bed are all guided with superior guiderails, which are assembled onto the machine, instead of welded;
2) In contrast, competitors use ordinary guiderail, and weld the rails onto machine body --- Such low cost manufacture brings along inferior quality, and easy to do harm on mechanical body;

5. Control System in Conventional and CNC H Beam End Face Milling Machine:
1) Background: This is a new type of End Face Milling Machine developed since by Wuxi JACK engineering team the year 2014;
2) Applicable Use: CNC H Beam End Face Milling Machine is especially suitable for workpieces with round shape and or special cross section, which sees wider application in recent years, under development of Steel Structure projects.
E. Summary on Wuxi JACK Steel Structure H Beam End Face Milling Machine:
1. Trend: Machine tools are developed out of customer demand. With explosion on heavy manufacturing industries, Steel Structure End Face Milling Machine also experiences rapid technical growth on performance and diversified capabilities;
2. As leading producer of conventional and CNC H Beam End Face Milling Machine, Wuxi JACK always committed to provide high quality products for customers.
