Tools made of high-perfor­mance cera­mics

A mate­rial like no other – with this self-confi­dent state­ment, the Japa­nese company XEBEC, toge­ther with the company Kempf from Reichen­bach an der Fils, presen­ted ist debur­ring and poli­shing tools made of high perfor­mance cera­mics at the EMO Hanno­ver 2017, which are charac­te­ri­zed by an unsur­pas­sed grin­ding and cutting force.

“Inno­va­tion begins with the impos­si­ble” – the head­line of the company philo­so­phy of the Tokyo-based manu­fac­tu­rer already makes clear the self-confi­dence with which XEBEC faces chal­len­ges. The goal is nothing less that the reali­za­tion of the seemin­gly impos­si­ble. For the Japa­nese it is above all important to auto­mate simple tasks as far as possi­ble so that people can engage in deman­ding and crea­tive activi­ties. Follo­wing this maxim, the Japa­nese also decla­red the state­ment many years ago, that it is a myth that manual debur­ring is the only way to remove burrs. The cera­mic fiber tools now presen­ted at EMO Hanno­ver 2017 will also contri­bute to the debur­ring process.

Up to 1000 cera­mic fibers ensure excel­lent cutting proper­ties

The products manu­fac­tu­red by XEBEC use abra­sive cera­mic fiber mate­rial instead of abra­sive grain. A single bristle, accord­ing to the Japa­nese, consists of 500 – 1,000 cera­mic fibers with excel­lent cutting proper­ties that act as cutting edges. XEBEC engi­neers empha­size three features of the inno­va­tive cera­mic fiber: “over­whel­ming grin­ding force”, “consis­tent cutting perfor­mance” and “no defor­ma­tion”, allo­wing CNC debur­ring and poli­shing. Accord­ing to the Japa­nese, the promi­sed “over­whel­ming grin­ding force” is due in part to the fact that the unique XEBEC cera­mic fibers have cutting edges compo­sed of the tip of each fiber bristle. This provi­des up to sixty times more grin­ding power than a nylon brush and the burrs can be remo­ved extre­mely thoroughly.

Inno­va­tive debur­ring tool in combi­na­tion with NC data record

At the joint stand, where the company Kempf from Reichen­bach (Fils) was also repre­sen­ted there was lively inte­rest due to the wide range of possi­ble appli­ca­ti­ons. In addi­tion to the cera­mic fiber tools, the recently intro­du­ced but already very success­fully used Back-Burr Cutter was presen­ted. The inno­va­tive debur­ring system, consis­ting of a speci­ally deve­lo­ped highly posi­tive debur­ring cutter in combi­na­tion with an NC data set gene­ra­ted for the custo­mer appli­ca­tion, is charac­te­ri­zed by the redu­ced machi­ning time as well as the process-safe and abso­lutely clean debur­ring of ellip­ti­cal edges on inter­sec­ting bores. The NC data set is indi­vi­dually program­med in advance for the customer’s appli­ca­tion and thus ensu­res opti­mum opera­tion with constant utili­za­tion of the tool cutting edge.

Kempf, who has been known for deca­des as a compe­tent and respec­ted part­ner in metal cutting, atta­ches parti­cu­lar impor­t­ance to the cost-effec­tiveness of the products offe­red. Redu­ced machi­ning times with a simul­ta­ne­ous increase in dura­bi­lity and process relia­bi­lity during machi­ning are important aspects here. Xebec offers excel­lent debur­ring solu­ti­ons for this purpose, whose products are exclu­si­vely avail­able in Germany from debur­ring specia­list Kempf.
