Hold it right there: Turning Performance

BIG DAISHOWA

With the introduction of its C3 program, BIG DAISHOWA recently expanded its BIG CAPTO toolholder line with the introduction of its C3 program, which is designed to increase efficiency and precision for small lathes.

The C3 series of MEGA NEW BABY chucks has a clamping range of 0.010″ to 0.630″ with a maximum RPM of 30,000. The chucks are said to be ideal for drills, reamers, taps and finishing end mills. Ultra-slim and strong, they provide reliable gripping for even the smallest workpieces.

The BIG CAPTO C3 square holders for turning applications come in left- and right-hand orientations. The C3-180-BH16R-2058 and C3-180-BH16L-2058 mono-block holders feature insert clamps that enhance rigidity and minimize vibrations and movement during cutting.

The new square toolholders are available in 90° and 180° types. The 90° type offers a variety of orientations, including perpendicular to the workpiece. Its compact design also allows for work in spaces that are tighter or have limited clearance. The 180° type allows the tool to machine harder-to-reach areas of the workpiece.

C3 boring bar holders also are available to clamp 6 mm, 8 mm, 10 mm or 12 mm boring bars. All turning toolholders feature through-spindle coolant.

REGO FIX

REGO-FIX recently added minimum quantity lubrication (MQL) machining to its powRgrip (PG) toolholding system to help shops improve production and tool life by reducing coolant consumption and shortening cycle times.

MQL machining is a clean, sustainable manufacturing technique that directs an aerosol of compressed air and a minimal amount of cutting oil (<50 ml/h) directly to the cutting area. In addition to significantly reducing coolant consumption, MQL machining reportedly reduces cycle times anywhere from 25% to 85%, while also improving chip evacuation for better surface finish and tolerance, and increasing tool life.

The REGO-FIX standardized MQL PG collets are designed for tool shanks according to DIN 69090-3 and available for HSK-A 63 and HSK-E 40 toolholders. They are designed for machines using one-channel, internal through-spindle MQL systems and are beneficial for virtually any machining application.

In many cases, chamber and cross-section areas within a toolholding system create turbulence that causes an irregular air/coolant mix ratio in the aerosol. However, the REGO-FIX PG MQL solution uses a coolant tube fitted with a lance that directs the mixture through the collet and directly to the tool for reliable coolant distribution at the lowest consumption rate.

Ceratizit

CERATIZIT recently enhanced its new MaxiLock-N turning toolholders by incorporating the company’s DirectCooling technology.

The MaxiLock-N turning toolholders incorporate two internal coolant holes that aim coolant directly at the cutting edge to prevent wear and ensure stable processes. Using these coolant holes, nozzles direct coolant to the clamping flat from above as well as from below to the flank. This additional flank cooling contributes to the tool’s ability to extend tool life by 60% compared to tools that cool only at the clamping flat.

To avoid interference with workpiece contours, the lengths of DirectCooling Series holders are ideally matched to one another and offer optimal stability and unlimited flexibility. This flexibility is further enhanced with the HSK-T universal standard interface for turning tools that ensures a straightforward connection to multifunction machining centers, such as those performing both milling and turning operations.

Japan USA Precision Tools

The new Takezawa-Seiki FHN Series floating holders from Japan USA Precision Tools, Bellflower, California, are said to follow the smallest offset to improve single-pass honing accuracy and extend tool life.

Designed specifically for one-pass honing, the FHN Series method compensates for small offsets such as tilt between the center axis of the tool and the pilot hole. By correcting the offset that occurs when attaching and detaching tools with the holder, it is now possible to achieve higher precision machining, according to the company.
