Shaft Output Power 

Integral Encoders For 

Closed Loop Control 

Power 

P [kW] 

Speed n [rpm] 

Chip removal rates are defined by the material's specific 

cutting speeds. Generally small tool diameters require 

high speeds and larger tools are operated at lower 

speeds. 

Large tools require high torque while small tools require 

less torque, but higer speeds. 

Integral motors utilized in the HC/HCS style spindle 

meet these requirements. 

The "field weakening" characteristics provide the high 

torque at lower speed. 

The spindles can be operated in the following modes: 

u S1 

Continuous power 

u S6 

Continuous duty with intermittent loading, a duty 

factor of 60% (S6-60%) for a cycle time of 2 minutes. 

Depending on the application requirements, the motor 

characteristics curve of power / torque relative to speed 

can be met. 

Rigidity is a prerequisite for the volume of metal to be 

removed and the surface finish required. This requires 

large shaft diameters, and accordingly large spindles, 

thereby large motors can be utilized. 

Due to the advances in motor development, the power 

density has been increased to such an extent that in 

many cases the output power far exceeds the application 

requirements. 

Oversized systems are costly, due to the size of the 

frequency inverter's required to operate them. 

Therefore operating the spindles at the required power 

level, the capacity of the inverter determines the power 

profile. 

Incorporating high resolution encoders into spindles, 

provides feedback and control of the actual shaft speed, 

and angular position of the shaft, at all times.

The advantages are as follows: 

u Smooth precise rotation and control at low speed 

u "C"-axis operation e. g. thread cutting 

u Shaft positioning within 0.001 degree 

u The drives high dynamic performance at full capacity, 

combined with the quick acceleration and deceleration 

times, allows the systems full power capacity to be 

utilized. 

GMN can interface the encoders to meet the selected 

drive systems requirements. 

The encoder system consists of a precision gear 

mounted to the rotating spindle shaft and a stationary 

sensor in the spindle housing readily accessible, for ease 

of service. 

GMN will optimize the performance of the complete 

spindle and drive package before shipment, and provide 

all the necessary parameters.

Advantages Of Hybrid Ceramic Bearings 

GMN "HC/HCS" series high frequency spindles utilize 

hybrid ceramic ball bearings. These bearings have 

standard steel bearing races and are matched with 

silicon nitride balls. 

Advantages of Hybrid bearings compared with normal 

spindle bearings are: 

Reduced wear 

The high degree of hardness of the balls, and the 

nongalling effect of the silicon nitride against metallic 

material lessens the wear. This is especially important in 

cases of minimal lubrication. In addition, wear particles 

will not embed themselves into the balls to further 

damage of the races. 

Rigidity 

Modulus of elasticity is bigger than steel, which 

increases the static and dynamic stiffness. The increase 

in dynamic rigidity depends on the ratio of bearing 

preload to the centrifugal force on the balls. 

Friction 

Because of the reduced spin-rolls ratios and lower 

Hertzian stresses, friction and respectively operating 

temperatures are reduced. 

Axial shaft movement 

As a result of the lightweight ceramic balls, centrifugal 

forces are reduced with a corresponding reduction in 

dynamic movement of bearing races. In addition, 

movements due to less friction and the lower coefficient 

of expansion of ceramics are reduced. 

Reliability of operation 

The low thermal coefficient of expansion of the ceramic 

balls lessens the reduction of the radial running fits in 

the bearings. These fits are less variable at higher 

temperature differences between races. 

Vibrations 

Radial forces and the moments acting on the bearings 

produce displacement between the balls and the 

retainer. Hybrid bearings reduce this effect and produce 

a positive influence on cage vibrations and stresses. 

Fatique life 

The fatique life is comparable when the Hertzian stress on 

the contact surfaces between rings and balls is 

similar. As a result of the minor weight of the ceramic 

balls the Hertzian stress is lower. 

Therefore hybrid bearings achieve longer life time. 

Accuracy 

Spindles of HC family are fitted with bearings produced 

according to GMN standard grade UP. They are 

distinguished from international standards due to 

excellent running accuracy.

Adjustable Bearing Preload 

Vibration Sensor 

Bearing arrangement and preload determine the rigidity, 

and influence the life time of the spindle system. 

For small speed ranges, and low speed operation the 

different versions of a solid preload arrangement are 

suitable. 

Large speed range variances, and high speed spindles, 

require a systems that will not allow the bearing preload 

to be influenced by either temperature or speed. 

These applications require spring preloading of the 

bearings. 

The above mentioned arrangements cannot be 

adjusted or changed, without disassembling the spindle. 

With the"Adjustable bearing preload" system the 

bearing preload can be optimized to the application, 

and prolong the lifetime of the spindle. 

The base preload of the bearings is determined by the 

highest speed requirements, and is set by spring 

preloading. 

The optimized settings over the speed range is varied 

through an internal piston which is actuated via either 

hydraulic or pneumatic pressure. 

As further advantage of the adjustable preload system is 

reduction of vibration. 

Unmonitored vibration can cause major damage to the 

spindle, machine tool and component being machined. 

GMN can provide sensors close to the front bearing set, 

which will quickly recognize any unbalance or high 

resonance which can cause catastrophic damage and 

shut-down the machine, or can plot out the curve on a 

display unit for analyzation and correction of the process 

or problem.

Tool Interface 

Taper Cleaning 

GMN can provide high frequency spindles to accept 

common tooling interface configurations. 

The prefered HSK style offers the following advantages 

versus the ISO taper: 

u High static and dynamic rigidity 

u High tool change accuracy and repeatability 

u Low axial movement during speed variations 

u Increased pull-in force as the speed increases 

u High torque transmission 

u Increase in personal safety due to the internal 

drive dogs (Form A/C) 

"Hollow tapered shanks with flat contact surfaces" are 

standard per DIN 69893. The different "FORMS" of a 

particular size are based on a similar shank size 

dimension. The tool flange is dictated by the mode of 

tool change. 

HC/HCS style spindles allow the use of tools with 

hollow shanks, type A, E or F according to interface 

design. 

Form E was developed for high speed without drive 

dogs. The torque transmission is actuated by adherence. 

Form A can also be used with manual tool change 

system provided in the HSP style spindles. This reduces 

the need for additional tool holders. 

Tools according to Form B/D cannot be used in the 

HC/HCS spindle, they are designed for different 

applications. 

The high demand to precision requires excellent 

cleaness at the tool interface. Automatic tool changing 

system call also for automatic cleaning systems. 

ISO taper cleaning can be operated at the taper surfaces 

whereas the HSK request also treatment of the plane 

face when the size it accepts. 

In accordance to the interface size different systems can 

be used: 

u Only air 

u Air or coolant in one line 

u Air and coolant in seperate lines

Clamping System 

Position Sensors 

Both the ISO taper style and the "HSK" hollow shank tool 

holders are clamped via a set of gripper fingers. The 

clamping forces are generated through a spring washer 

pack, included in the power drawbar. 

The centrifugal forces exerted by the balls in the 

pressure intensifier, multiplies the pull in force on an 

ISO taper style system. It is also speed dependent. 

Increases in the pull in force for the HSK style tool 

clamping system is by the centrifugal forces on the 

internal gripping mechanism. 

Tool un-clamping on either system is accomplished by 

actuating an internal piston with either hydraulic or 

pneumatic pressure. 

An internal cylinder mounted at the rear of a spindle, 

along with a gripping mechanism supports the shaft 

during unclamping, to prevent the pressure exerted 

through the shaft from damaging the spindle bearings. 

During operation the gripping mechanism is 

disconnected. 

These designs provide low vibration and a high safety 

factor for high speed quick change tool clamping 

systems. 

The GMN spindles are equipped with proximity sensors 

to allow for proper, trouble free operation during tool 

changing. 

u Tool change 

Depending on the size and nominal speed of the 

spindle, a variety of sensor arrangements can be 

applied for feed back to the machine control, about 

the tool changing cycle. 

Variation A 

A (2) two sensor arrangement for monitor the 

position of the piston, either "forward" or "back". 

Variation B 

Depending on the internal space constraints the 

drawbar can be monitored for "tool clamped", 

"unclamped", "clamped no tool", with (3) inductive 

proximity switches or one analog sensor. 

Variation C 

By utilizing the "taper cleaning" feature the air flow can 

also provide a signal that tool is improperly sized or 

not clamped correctly. This method can increase tool 

changing times. 

u Rotation of shaft 

If the spindle size and speed restrict the use of 

an encoder, GMN can provide alternative sensors for 

actual shaft speed, and also "zero speed".

Air Purge 

SP 

Fluid-Ring Seal 

FR 

Pressurized air is used to prevent the ingress of 

contamination into the bearing system. 

A continuous flow of clean dry air fills the closely 

machined gaps between the stationary and rotating 

members of the spindle. 

The air stream also stops the spent oil lubrication from 

existing at the front of the spindle and away from the 

work piece. 

GMN has patented a “Fluid Ring“ seal which can be 

incorporated in most GMN spindle designs, can operate 

in heavy external coolant and dust conditions, is NO 

speed limitations, and requires NO air.

Coolant Through Shaft 

Coolant Through Spindle Housing 

The internal coolant supply provides cooling directly to 

the cutting edge also at difficult form of workpieces. 

In accordance to the interface size and dependent on 

the maximum operating speed different systems can be 

used: 

u Only air 

u Air or coolant in one line 

u Air and coolant in seperate lines 

Adjustable nozzle 

For cooling of tool and workpiece the medium is 

supplied through spindle housings and nozzels to the 

cutting surfaces. 

Compressed air, cooling lubricant/air mixture or cooling 

lubricant can be used. 

The representation below is with cooling lubricant as 

medium.

A Method For Controlling 

Axial Shaft Growth 

Measurement Of The 

Axial Shaft Growth By Sensor 

°C 

Precision machining requires the position of the cutting 

edge of the tool to be maintained. 

Temperature variations and centrifugal forces at the 

balls and bearing races, can cause axial movement of 

the tool mounting face of the shaft. 

axial movement 

The "centrifugal forces" factor can be calculated and the 

speed dependent shaft movement can be compensated 

by through the machine tool control. 

Measuring the shaft temperature at the bearing during 

operation is difficult. 

Experience has shown that by measuring the 

temperature at outer diameter of the bearings, 

approximate temperature variations can be established 

and the axial movement compensated for. 

Axial shaft growth which is caused by fluctuations in 

temperature, can produce process errors in milling 

applications. GMN can incorporate a sensor at the front 

of the spindle to record the exact growth and the CNC 

machine control can compensate for the movement. 

The measuring system which consists of an electronic 

controller which conditions the signal provided by the 

sensor has data storage capacity which provides 

immediate response after spindle exchange.

Pick-up Spindle « Multi Couplings 

GMN spindles can be supplied with multi-couplings for 

energy and fuel supply. 

This reduces the unproductive spindle replacement 

times, or - depending on the design - can even make 

possible the automatic replacement of spindles, thus 

increasing the flexibility of the machine. 

Quick Couplings

Spindle Testing Stand 

Before GMN machine spindles for high speed machining 

(HSC) are delivered, they are tested on a test stand 

specially developed for GMN. 

One reason for this is that motor spindles become more 

and more complex and on the other hand their reliability 

is guaranteed by this. 

The test in which the setpoints as well as cycle and 

switching times are specified runs automatically. 

Finally a test certificate is produced in which all measured 

values are documented. 

2 motor spindles with different parameters can be tested 

simultaneously. 

Here it was proven that 180 cycles are sufficient to 

guarantee the highest possible reliability. 

In every cycle the spindle is turned to maximum speed 

in a specified time within seconds, the shaft encoder 

signals are checked, the spindle is braked under defined 

conditions after a certain time, the tool change is 

performed and the signals of the position sensors are 

measured. 

The position of the tool clamping system can be 

determined optionally analogously or through individual 

switches. 

Furthermore the following are acquired: motor current, 

voltage in the windings, temperature of the winding and 

of the foremost bearing and, depending upon spindle 

equipment, functioning of coolant supply through the 

shaft and the adjustable bearing preload.
