Modular Tooling for Use in Mazak Turning Centers
Exsys Tool Inc. has expanded its line of Preci-Flex modular tooling systems to include a 10,000-rpm, 1:1 ratio rotary tool for Mazak Quick Turn and QTU-series turning centers.
Exsys Tool has expanded its line of Preci-Flex modular tooling systems to include a 10,000-rpm, 1:1-ratio rotary tool for Mazak Quick Turn and QTU-series turning centers. The faster toolholders are said to match the processing speed of optional 10,000-rpm machine spindles to boost productivity and achieve quality surface finishes.
Manufactured by Eppinger, the line of tooling systems offers flexibility and precision. The short, compact design with monoblock housing provides high torque transmission and rigidity, resulting in increased machining accuracy and improved productivity. Additionally, its conical and flat-face planar interface enables the use of either an adapter or a standard ER collet. This enables the mounting of collets, end mill holders, expanding collet chucks and shrink-fit tooling on a single base holder.
The tooling system also features a compensating clutch with a floating coupling between turret drive motor tangs and toolholders that automatically compensates for misalignments. The resulting high-precision alignment reduces vibration and tool chatter, which in turn makes for longer tool life and better surface finishes.Available in a range of sizes, the system includes both horizontal-type, 90-degree radial holders and vertical, straight-offset axial holders. Every toolholder provides repeatability within 5 microns. The system also reduces machine downtime and enables tooling adapters to be interchanged between fixed- and rotary-base holders for fast, economical machining.
The book on hydraulic toolholders is that they are fussy to set, fragile to operate and expensive to buy. So why do many shops choose them over other holders that seem less demanding? This Chicago mold builder has good reasons for its choice.
The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
