cutting speeds to be used. Jabro composite PCD cutters have a special PCD blade design that improves thermal wear resistance and enables higher feed rates to be employed. The cutters are designed and manufactured with shear angle variations (neutral, positive or negative) and are available in a range of sizes from 6mm to 16mm diameter. All Jabro PCD cutters have two internal through coolant channels for efficient cooling and temperature control. The new range of Seco
Feedmax drills – available in 4mm to 25mm diameter sizes – feature a 120° degree drill point design and sharp and durable PCD cutting edges. A particular strength of the drills is their ability to cut for long periods of time without any loss of performance or need for
jaws. They can be used with an extensive range of dedicated fixtures, resulting in reduced set- up times for both new and repeat work.
Sometimes, two or four components are clamped at a time, enabling twice or four times the number to be processed per cycle in comparison with more conventional vices. The system effectively cuts by a factor of two or four the frequency of tool changes, reducing non-machining time and speeding cycle time per component. A majority of components are machined from aluminium forgings, while solid billet currently accounts for some 15% of throughput – work that was previously subcontracted but is steadily being brought back in house.
Mr Edwards concludes: “Chick vices enable us to remain competitive, whether we are manufacturing batches in the thousands or much smaller runs, ensuring that we provide a highly flexible and responsive service to our customers. “Furthermore, the accuracy of the workholding units supplied by 1st MTA and the quality of the support provided by their applications and installation engineers continues to underpin the precision machining that is crucial for our safety critical products.”
replacement and their inherent sharpness and high dimensional tolerance enables excellent surface finishes and challenging hole tolerances to be achieved. “The new range of PCD tools is an important addition to our extensive composite material cutting tool portfolio, and will be
of particular interest to aerospace, marine and motorsport precision component manufacturers,” comments Seco’s technical and marketing manager, Mike Fleming.
