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

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.

Shaving More Seconds Off Quick Changeover

Using the BENZ Solidfix system, operators no longer have to remove the main tooling unit itself. Instead, they only change the adapter that holds the pre-measured tool. Setups can be changed in less than 15 seconds without using any special tools. The shop also doesn’t have to carry as many expensive live tools because all they need are the quick change adapters.
Take a look at how this job shop uses a highly versatile modular quick change collet system to perform setups and changeovers in speeds of 15 seconds or less.

S-Pads Replace Collets in Multi-Spindle Shops

S-pads from Hardinge are much faster to change than collets from job-to-job and can be shared between many brands of machines, whether the master collet is mounted directly in a machine spindle (single or multiple), in a collet adaptation chuck, or in a collet block.

Innovations in Workholding

Ideal for machines with short stroke cylinders, the ROTA NCX from SCHUNK is a power lathe chuck with a quick jaw change system that can decrease set up time up to 80 percent and be changed out with a repeat accuracy of 0.02 mm. It boasts a large through-hole and easily replaces conventional lathe chucks. 
Workholding must be updated to make full use of the small lot flexibility that machine tools now offer so that the same part cost can be achieved in much shorter production runs. Here are some of the latest advances in workholding technology for shops to consider. 

Full Grip Jaws Minimize Distortion for Thin-Walled Parts

Aluminum full grip jaws from Dillon are available from 5 in to 24 in diameter and are ideal for machining thin walled parts used in valves, cylinders, specialty wheels and gears, housings and enclosures, adaptors and connectors,  aluminum and steel shells, flanges, retainer rings, automotive smog control air pump rotors, gas turbine parts, thin-wall tubing and cylinder liners for diesel engines and more.
