PRODUCE PRECISE PARTS WITH PRECITEMP®!

• Auto­mat­ed
• Reli­able
• With­out per­ma­nent monitoring

The ground­break­ing PRECITEMP® tech­nol­o­gy from Roed­ers enables realy unmanned parts pro­duc­tion, even with tight tol­er­ances. Ther­mal dis­place­ments of the machine, mov­ing zero points or chang­ing machine geome­tries are overcome:

• 3‑xis or 5‑axis
• If nec­es­sary, milling and grind­ing in one set-up
• Space-sav­ing, high­ly effi­cient automa­tion solu­tions for one or more machines
• Direct clamp­ing of parts or on pal­lets, mixed oper­a­tion also possible
• Short tool change times

The new RXU2000 from Roed­ers achieves max­i­mum pre­ci­sion when work­pieces and moulds with par­tic­u­lar­ly large dimen­sions have to be machined. Designed for excep­tion­al accu­ra­cy com­bined with high per­for­mance in machin­ing hard­ened mate­ri­als, the machine has a work­ing area of 2,000 x 1,800 x 800 mm. The work table is designed for loads of up to 5.0 t. The Z‑axis stroke has been inten­tion­al­ly lim­it­ed in order to ensure max­i­mum accuracy.

RCF 150 — lin­ear very com­pact machine automa­tion for one or sev­er­al machines placed in a row:

• Only 1.5 m wide includ­ing shelves
• Max. work­piece weight 150 kg
• Grip­per change for dif­fer­ent pal­let types and tools
• quick­ly installed due to mod­u­lar design
• easy to expand anytime

A 24 cav­i­ty injec­tion mould for lens­es for mobile phones had been jig ground on a RHP500 machine with high­est pre­ci­sion pos­si­ble. This appli­ca­tion became espe­cial­ly chal­leng­ing, because the holes had only 8 mm diam­e­ter, the area to be jig ground began 15 mm below the mould sur­face and reached a depth of 45 mm. In con­se­quence, the holes had to be ground cylin­dri­cal with high­est pre­ci­sion on a total length of 30 mm. The request­ed cylin­dric­i­ty of 0.5 µm was achieved on all 24 cavities.

Milling and Grinding

Cut­ting or grind­ing tools with up to 200 mm diam­e­ter may auto­mat­i­cal­ly be changed into the main spin­dle by a new­ly devel­oped tool chang­er, which is placed below the bridge of the machine. For each tool an adjust­ed cool­ing sup­ply is changed as well, which allows per­fect cool­ing where need­ed for the cut­ting process.

Moulds for liquid silicone rubber (LSR)

Part­ing sur­faces of injec­tion moulds for liq­uid sil­i­cone rub­ber (LSR) are machined with high pre­ci­sion to final dimen­sions. No rework is nec­es­sary. The moulds are direct­ly used for flash-free production.

For min­i­miz­ing train­ing peri­ods and facil­i­tat­ing the change of oper­a­tors among machines with dif­fer­ent NC-Con­trols, Roed­ers machines may be pro­grammed in HEIDENHAIN®#-NC-Code (with lim­it­ed scope) or ISO-Code (G‑Code). The NC-Pro­gram is cre­at­ed with sim­ple macros at the con­trol. Oper­a­tors know­ing the NC-com­mands in the respec­tive code do not need extra training.

The com­bi­na­tion of high pre­ci­sion air bear­ing spin­dles run­ning up to 90000 rpm with the lin­ear motor direct dri­ve tech­nol­o­gy of the Röders HSC machines allow for up to now unknown qual­i­ties in the watch indus­try. On the exhi­bi­tion EPHJ in Gene­va spe­cial­ists were con­vinced of the supe­ri­or qual­i­ty direct­ly at the machine. With the long-stand­ing com­pe­tence of Röders in automa­tion the machine may be adapt­ed to a high­ly effi­cient man­u­fac­tur­ing process at the customer.
