Economy Automatic Toolholders Available for Range of Lathe Sizes, Types
Automatic Tool Changers Inc. introduces a complete range of economical tool turrets for CNC lathes and turning centers, including replacements for the now-discontinued Dorian turrets used on Haas TL-series lathes. All turrets use a three-piece Hirth tooth coupling for high accuracy and maximum rigidity, enabling turrets to index without the tool carrier lifting. The turrets can be used in any orientation and are totally sealed for use in the most demanding environments.
Disc-type turrets with static tooling are offered in six frame sizes fitted with an electromechanical, hydraulic or servomotor drive train. Turrets with axial- or radial-oriented live tooling are also available in the most popular sizes for either BMT or VDI tooling, standard spindles and toolholders. Square toolpost-type turrets with an electromechanical drive are offered in four basic frame sizes designed for use on flatbed lathes and vertical turning lathes.
To simplify the installation, the company also offers an optional self-contained controller that enables automatic, semi-automatic and manual operation.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
