5 axis machining center HSTM

Why give away potential?

Make use of your com­pet­i­tive advan­tages! The 5 axis machin­ing cen­ter HSTM with hor­i­zon­tal com­po­nent ori­en­ta­tion is par­tic­u­lar­ly suit­able for the machin­ing of tur­bine and com­pres­sor blades, blisks/impellers and/or radi­al com­pres­sor fans. The slide-ways have been inclined at an angle of 45° to the front to ensure an opti­mum mass dis­tri­b­u­tion, excel­lent load­ing pos­si­bil­i­ties and an excel­lent view of the work­ing area.

Configuration Examples


Precision and economics

Where the attain­able accu­ra­cies and sur­face qual­i­ties are con­cerned, the HSTM even exceeds the high­est demands for mod­ern blade machin­ing. Con­tin­u­ous max­i­mum pro­duc­tiv­i­ty is ensured by its stur­di­ness and rigid­i­ty, as well as by the inte­gra­tion of an HSC-support.

Extreme adaptability

The com­pact con­struc­tion of the machine per­mits a rapid and flex­i­ble instal­la­tion at the cus­tomer plant – with­out any spe­cial require­ments as to the nature of the floor foun­da­tion. The machine con­sists of a one-piece base, where all units have been arranged in an ide­al way for the machin­ing of hor­i­zon­tal­ly clamped components.

Ergonomics and productivity

The inclined posi­tion of the axes in the machin­ing area guar­an­tees an excel­lent chip removal. Stan­dard inter­faces at the rotary axes and periph­er­al com­po­nents are the essen­tial char­ac­ter­is­tics of this machine, being designed for utmost pro­duc­tiv­i­ty. In arrang­ing the oper­at­ing and ser­vice ele­ments, spe­cial impor­tance was attached to their ergonom­ic layout.

The HSTM-series stands for:

  • Excel­lent up-time
  • High sta­t­ic and dynam­ic rigidity
  • Ther­mo-sta­bil­i­ty in all axes
  • Mod­u­lar construction
  • Ergonom­ic design
  • Motor spin­dles with high speed and strong torque
  • Utmost machine dynam­ics for a short com­po­nent machin­ing time
  • Best acces­si­bil­i­ty for main­te­nance and service
  • High­est demands regard­ing accu­ra­cy and sur­face quality
  • Auto­mat­ic chang­ing of tools and components
  • Excel­lent sur­face qual­i­ties owing to hydro­sta­t­ic A- and C‑axes

Machining of turbine blades

Do you need an extra­or­di­nary solu­tion – not just a compromise?

In avi­a­tion even the tini­est fault can be the cause of a big cat­a­stro­phe. This is why we are very well aware of our great respon­si­bil­i­ty to pro­vide excel­lent qual­i­ty and sus­tained reli­a­bil­i­ty with our solu­tions. Thus, it is insuf­fi­cient to just meet the gen­er­al­ly accept­able qual­i­ty stan­dards, we would rather aim at exceed­ing them time and time again. For pre­cise­ly this rea­son, our tar­get is to find even more effi­cient solu­tions with ever increas­ing advan­tages for all our customers.

Our sys­tem know-how, which is vis­i­ble in our entire process chain, is a deci­sive plus point and of great assis­tance to you in fur­ther enhanc­ing your com­pet­i­tive posi­tion, as it not only pro­vides you with a con­sid­er­able increase in your oper­at­ing effi­cien­cy, but also in your safe­ty and prof­itabil­i­ty lev­els. We are proud of our capa­bil­i­ty to make avi­a­tion safer by our inno­v­a­tive machin­ing tech­nolo­gies and unique cus­tomised pre­ci­sion machines.

Of course this applies not only for our cus­tomers from the avi­a­tion sec­tor, but also to our cus­tomers from oth­er indus­tries. The ben­e­fits from our know-how and greater demands on pre­ci­sion and qual­i­ty have helped them all main­tain an advan­tage over their competitors.

Machining of blisks

Most mod­ern technology

In par­tic­u­lar where the pro­duc­tion of air­craft engines is con­cerned, the demand to reduce con­sump­tion acts as the dri­ving pow­er for inno­va­tion. This demand can exclu­sive­ly be met by a reduc­tion in weight along with an increase in efficiency.

This sit­u­a­tion has pro­voked the use of high­ly devel­oped, light-weight, heatre­sis­tant mate­ri­als and the com­bi­na­tion of indi­vid­ual com­po­nents, con­se­quent­ly a reduc­tion of fits and joints. Owing to high­er speeds, espe­cial­ly cir­cum­fer­en­tial speeds, as well as three-dimen­sion­al blade con­fig­u­ra­tions, this increase in effi­cien­cy caus­es greater demands on com­po­nent performance.

The chal­lenges men­tioned have led to the devel­op­ment of blisks, com­po­nents where func­tions have been inte­grat­ed to a high degree to replace the fit­ting of indi­vid­ual blades.

Effi­cien­cy as an argument

Today, tur­bine man­u­fac­tur­ing sim­ply can­not be imag­ined with­out blisks. They have large­ly tak­en the place of indi­vid­ual blades mount­ed on disks. The word blisk com­bines the terms blade and disk.

Man­u­fac­tur­ing a blisk means the lat­er­al milling of blade pro­files from a forged disk using a CNC-milling machine. This disk is clamped to the A‑axis and can be rotat­ed while being machined by the 5 axes milling head. Here, piv­ot­ing is exclu­sive­ly done by the milling head. The intri­cate geom­e­try of such a blisk requires a lot of know-how and mature state-of-the-art milling machines.

All this can be tak­en for grant­ed at HAMUEL. 

Vorteile beim Ein­satz von Blisk:

  • No join­ing of blade foot and disk
  • No mount­ing
  • No influ­ence of a pos­si­ble joint on com­po­nent behav­ior, for exam­ple owing to cen­trifu­gal forces at high speeds
  • Increased effi­cien­cy of the turbine
  • Longer com­po­nent life, as no cracks can form at the blade feet
