Universal Grinding Machine WOTAN® S6U for Highest Precision

The Saxon grind­ing machine man­u­fac­turer WEMA Glauchau GmbH will be dis­play­ing the 6 series of its uni­ver­sal grind­ing machines at AMB 2012 for the first time. The WOTAN® S6U  uni­ver­sal grind­ing machine mea­sures approx. 6 m in length and 2.8 m in width and can be used to grind large work­pieces of up to a length of 1,400 mm and a weight of up to 650 kg (at the man­drel nose) inter­nally and exter­nally as well as flat and even. The WOTAN® S6U is also avail­able as an XL ver­sion with optional work­piece lengths of up to 2,200 mm. With both inter­nal and exter­nal cir­cu­lar grind­ing oper­a­tions, the max­i­mal grind­ing diam­e­ter equals 650 mm.

The grind­ing depth of the uni­ver­sal cir­cu­lar grind­ing machine on dis­play equals 900 mm. Since the begin­ning of this year WEMA Glauchau is also offer­ing its cus­tomers the option of pre­cise cir­cu­lar inter­nal grind­ing work on espe­cially long work­pieces with a depth of 1,200 mm. This depth was pre­vi­ously dif­fi­cult to achieve with inter­nal cir­cu­lar grind­ing oper­a­tions since the ratio of 10:1 (between the length and the diam­e­ter) was con­sid­ered to be a lim­it­ing fac­tor. WEMA how­ever suc­cess­fully met this tech­ni­cal chal­lenge and was thus able to deliver the first grind­ing machines with a grind­ing depth of 1,200 mm.

The dis­played grind­ing machine has an inter­nal and exter­nal grind­ing unit fea­tur­ing one man­drel tur­ret (B2 axis) each. The inter­nal grind­ing unit is equipped with a high fre­quency man­drel with a max­i­mum speed of 36.000 rpm which also allows the use of var­i­ous belt-dri­ven grind­ing man­drels. The head­stock also installed there along with the exter­nal grind­ing unit with its two grind­ing man­drels enables lon­gi­tu­di­nal grind­ing and plunge-cut grind­ing. WEMA recently also devel­oped a tech­ni­cal high­light in this area which will be avail­able to cus­tomers in future as an optional extra that allows exter­nal cir­cu­lar grind­ing oper­a­tions to be car­ried out behind the steady rest. This can usu­ally only be done with purely exter­nal cir­cu­lar grind­ing machines. How­ever, with the newly devel­oped uni­ver­sal cir­cu­lar grind­ing machine of the 6 series, which will be avail­able soon, cus­tomers will also be able to exter­nally cir­cu­lary grind sur­faces of work­pieces mea­sur­ing up to 2,000 mm in length and sit­u­ated up to 500 mm behind the steady rest.

WOTAN® S6U for the internal, external and plane surface grinding of a variety of workpieces – live at AMB

Along with the inter­nal, exter­nal and plane sur­face grind­ing, the dis­played grind­ing machine also enables the inter­nal and exter­nal grind­ing of Poly­gons.

Accord­ing to the mar­ket­ing man­ager at WEMA Glauchau GmbH, we will def­i­nitely be attract­ing the inter­est of vis­i­tors at AMB with the flex­i­bil­ity, effi­ciency and indi­vid­u­al­ity of our WEMA S6U.

WEMA will be pre­sent­ing itself at AMB in Hall 8 at Stand 8C60.
