Fulfilling Modern Micromachining Demands on a Legacy Machine

Looking for a creative way to achieve the requested specifications for a potentially lucrative micromachining job without having to invest in a very expensive specialized machine tool? A spindle speeder may be your best – and only – way to secure the deal.

Stick to the Story

The special Dual Contact CAT50 stick turning toolholder developed by Briney for an Okuma MacTurn 550 milling/turning center. The dual contact of the toolholder taper shank and the toolholder flange eliminates pull-back of the toolholder. The steep taper contacts the spindle taper and flange contact on the spindle face, making a solid union in both the axial and radial planes. As a result, dual contact toolholders are resistant to axial movement because the face contact prevents the toolholder from being pulled up into the spindle at high speed.
Check out how a special dual contact stick turning toolholder developed by Briney Tool Systems eliminated the need for one shop to re-engineer their catalog of lathe stick tools.

How the Right Offline Tool Presetter Affects a Shop

Most tool presetters are made for the floor environment. Many shops situate the presetter in the middle of machining center cells so that the operators can easily and quickly set tools while production continues nearby. 
The old saying “it won’t make chips – not worth it” doesn’t apply anymore. Considering the accelerating pace of change in technology and the relentless competition your shop faces, how can you possibly afford not to use a presetter?

Beat the Competition on a Budget with this Entry-Level ‘Automation’

A Unilock zero-point clamping system uses air pressure plus die springs to drive clamping pins against a tapered clamping knob that is attached to a base plate, fixture or directly to the workpiece for easy palletization of single or multi-chuck applications.
The way we machine parts has changed significantly over the years. Now it’s time to change how we think about workholding too.  

Is BIG-PLUS An International Standard?

This comparison of licensed BIG-PLUS vs. unlicensed BIG-PLUS tooling shows how little or no taper contact in the unlicensed tool holder can allow “float” in the spindle taper with no positive radial location, causing large cutter runout and immediate fretting corrosion on that spindle face that can severely damage the spindle.
Buyer Beware: This system has not been standardized by any governing body. If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original for half the price, you risk unsatisfactory performance and/or damage to very expensive spindles. Here’s why.

Getting a Better Grip on Toolholding Systems

The Power Clamp Comfort NG
from Haimer is an inductive shrink fit machine that can be adjusted to the length and diameter of the chuck. As a result, only the clamping range of the chuck is heated, which considerably reduces cooling time and increases safety.
This precision machine shop discovered the many ways that balancing and heat shrinking their toolholders gives them repeatable and predictive results in machining aluminum components for aircraft.
