HAAS SPINDLE
5
Every spindle drawing I was able to get was slightly different. When I read chat online, the common complaint was the tools wearing at the large end of the taper.
Presenter
Presentation Notes
The complaint about the Tool’s taper wearing at the large end was attributed to the thickness of the spindle at the bottom where the bearing meets the ID taper. The cross section is considered to be the weak point and flex’s under load. You can read for yourself by searching for “Haas Spindle”.
SPINDLE CONSTRUCTION

Two Double anglecontact bearingsat the spindlenose and two Ballbearings at the topend of the spindle.

Presentation Notes
Ball type LM guides are less expensive and have about ½ the expected life of Roller type. They are even measured at ½ the distance.

Presentation Notes
The life of the LM guides without any load is 5.7 times roller vs ball. When used under the load in actual use, it is 2 times roller vs ball.

THERMAL COMPENSATION
13
Haas Thermal Comp
Doosan DNM Thermal CompThe Pre-Tensioned ball screws are “stretched” to the warm state so Thermal comp can be eliminated. The DNM Series use a Sensorless type compensation which is established at the factory and creating a Matrix for each model based on testing over a long period of time in the “Reliability bay” shown on the next page. No Operator intervention is required.
TEMPERATURE CONTROLLED TESTING ROOM
14
This room is used to test and map the thermal growth and straightness deviation from extreme temperature swings from an ambient temperature of 70 degrees.
There are 5 ThermalCompensation typesused by Doosan
1) Active Cooling via oilcooler / heat exchanger
2) Sensor type3) Sensor less type4) Straightness

Presenter
Presentation Notes
To configure a Haas like a Doosan becomes rather expensive which makes it not cost effective when comparing what’s really under the hood.

Presenter
Presentation Notes
Interesting NOTE: Haas does not report the continuous ratings, only the max which are considered intermittent which could be 1.5 min or 3 min or 5 min. That’s why you can’t put a Haas into high production automated situations.

1-1. Doosan Adaptive Feedrate Control (DAFC)
DNM (8,000rpm) Standard Control Feature
DNM II (8,000rpm) is equipped with exceptional control feature that significantly improves efficiency (standard feature)
Adaptive Feedrate Control:• Monitors the amount of spindle load to adjust feedrate adaptively• When cutting conditions favorable, NC increases feedrate to reduce cycle
time• Results an Improved Cycle Time & Cutting Process Protection due to
Optimized Machining Conditions
Presenter
Presentation Notes
Adaptive Feed will reduce the cycle time by automatically speeding up the non-cutting/feed moves by an adjustable %. It is also capable of reducing the feed rate when it encounters heavy stock. There is nothing to change in your programming and it is very easy to use.
2-1. Big Plus Standard
DNM 8,000rpm
Standard Big Plus on all DNM Series provides better machining performance
Big Plus: Dual (Taper & Face) Contact offers up to 40% additional Radial Rigidity• Better finishes• Greater Stock Removal Rates• More Accurate Boring• Less Blending
Big Plus w/o Big Plus
Presenter
Presentation Notes
Big Plus can be used along with standard CAT or BT tooling. It is very helpful when you encounter chatter or heavy Z axis loads from large drills. It virtually turns a 40 taper tool into a 50 taper tool because the contact area of the two face contact is nearly equal to the large diameter of a 50 taper tool.
