Sandvik Cutter Completes Cubing in a Single Operation
To boost the first-stage roughing operation on cast aluminum parts for the automotive industry, Sandvik Coromant introduces its M5Q90 tangential milling cutter.
M5Q90 cutter bodies from Sandvik Coromant are customized by customer specifications, operating at speed as fast as 20,000 rpm. However, the cutting bodies offer the same design of tip seat, coolant channel, lead angle and rake angle.
The cutter body tool life is extended in engineered solutions with PCD inserts protected by rows of carbide inserts, a design that is said to enable an increase to the depth of cutting capability. While the basic tool with PCD inserts offers 2-4 mm (0.079"-0.157") depth of cut, this is boosted to as deep as 4 mm (0.157" ) using the engineered solution with protective rows of carbide inserts.
Aluminum cylinder heads and engine blocks benefit, typically in automotive sectors or Tier 1/Tier 2 suppliers, according to the company. Capable of both face and shoulder milling, this cutter is also said to be especially useful for applications in the general engineering and aerospace sectors.
Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
Workholding for turning is usually fairly basic: The selection comes down to chucks or collets. This article looks at when to consider the collet chuck and what kind might be best for a given application.
An ongoing effort towards more efficient operations drove this shop to take a closer look at indirect material usage, subsequently leading to implementation of a new system for tracking toolroom inventory.
