O furo do carretel é um elemento central em componentes hidráulicos, como corpos de válvulas ou bombas de pistão axial. A usinagem de acabamento com ferramentas para acabamento fino sempre foi uma das principais competências da MAPAL. Com novas soluções de ferramentas para a pré-usinagem, o especialista em ferramentas consolida sua posição como parceiro tecnológico holístico. Os clientes se beneficiam de um conceito de usinagem completo de um único fornecedor – desde a realização do furo piloto até a usinagem fina.
The focus is on two new tools: the pilot drill with three or five cutting edges for different casting
properties enables efficient and highly economical component piloting, reducing machining
steps and saving tool changes. While the threelipped core drill is used for stable raw parts, the
option with five cutting edges offers precise results at high feeds in unstable casting conditions.
Like the pilot drill with three cutting edges, the solid carbide boring tool with three cutting edges is based on MAPAL’s patented multi- chamfer technology. This ensures clean chip removal and prevents swirling in chip removal – including at drilling depths up to 10xD. Targeted internal cooling enables long tool lives and also increases process reliability.
Both tools are optimally tailored towards subsequent fine machining. Coordinated processes,
reduced scrap rates and maximum cost-effectiveness help create innovative solutions for fluid power – with measurable added value for the customer.
