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. For opti­mum mass dis­tri­bu­ti­on, excel­lent loa­ding con­di­ti­ons and an unob­s­truc­ted view of the machi­ning pro­cess, the gui­de sys­tem is incli­ned to the front at an ang­le of 45°.

HSTM

Configuration examples

  • 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 (as an option)

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.

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 cus­to­mi­zed 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, heat-resistant 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.

Advan­ta­ges of using 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

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‑axis 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.
