Computer Numerical Controlled (CNC) lathes have, in more recent years, been quickly replacing older multi-spindle style lathes. This is mainly due to the ease of programming, operation, repeatability and set-up. After initial set-up and programming, the machine can continue to produce parts under limited supervision by the operator.

A high level of skill is needed by the machine programmers since knowledge of both machining and computers is necessary. However, the need to have intimate knowledge of the intricacies of their machine is not as important for CNC lathe operators as it is for manual lathe operators. This fact allows different operators to work the same machine as well as for a single operator to move from machine to machine with no variation in the product they output. Ultimately, this freedom of machine and operator allows for shorter production and lead times as well as a more consistent final product.

Though the machines may vary between companies, the basic elements are the same. Tool holders are held and indexed by a turret. The workpiece is held by the spindle and there are slides that allow the turret to operate along multiple axes simultaneously. In response to Occupational Health and Safety standards, most CNC lathe machines are completely enclosed.

Header Die & Tool has one of the best CNC turning departments in the industry. With over 150 years combined experience, our toolmakers are forward thinking, solution oriented and detail driven. At HDT, no run is too small. We do set-ups for any size run, (1) piece to more than (1,000) pieces and anything in between. HDT uses top-of-the-line CNC Turning Centers from the most trusted names in the industry including Mazak and Hardinge. Having the best equipment and the most experienced toolmakers translates into higher quality parts with shorter lead times. HDT strives to stay current on the latest tooling and techniques in the industry allowing us to deliver a superior product to our customers.

BENEFITS OF CNC LATHE TURNING

• CNC machines can be operated continuously 24 hours a day, breaking only for occasional maintenance
• Once programmed, CNC machines can manufacture a desired part hundreds or even thousands of times consistently and efficiently
• Updates are easily made by improving the software used to drive the machines
• CNC machines can utilize advanced design software allowing the production of pieces that cannot be made by manual machines
• After programming, only one person is required to supervise several CNC, which allows HDT to provide more capacity and in turn, shorter lead times.
• Though a skilled toolmaker can create the same piece many times, if all pieces are carefully studied, each will vary slightly. CNC machined pieces will be manufactured consistently with exact precision

CNC LATHE TURNING SPECIFICATIONS & CAPABILITIES
