Turning

Two state-of-the-art Swiss-style lathes from Marubeni Citizen-Cincom Inc. are capable of precise cutting.

Due to its heavy cast iron construction, smooth power transmission and precision thrust and ball bearings in the head stock and spindle, the bench lathe provides years of trouble-free, precise turning. The Bench Lathe is the right choice for turning small metal parts.

The speed and precision of the OptoFlash enables 100+ static measurements on parts up to 60mm in length and 20 mm in diameter within two seconds at U95 = 1 µm + D/200 (D in mm) with the ability to switch from one-part type to another with just one click (flexible gauge). It captures images of the component over the 360° degrees, automatically combining several images to determine both part optical axis and measurements of the features.n

It represents a highly productive alternative to conventional turning where 80° & 35° corner inserts are fed in the same direction, and instead utilizes all 4 directions available on conventional 2 axis lathe (+Z, -Z, +X, -X) to maximize material removal. The double-sided positive SuperTurnZ inserts have the same axial & radial rake angle and capability as standard ISO positive inserts, allowing for low cutting forces, but with double the cutting edges and much higher feed rate capabilities.

With this new tool, V or D-style inserts with just two cutting edges and lower stability (ISO VBMT, VCMT, DCMT) are replaced with triangular cutting inserts with three cutting edges and high stability. These three-edged inserts allow for a 50° undercut angle, ideal for profiling operations. Since the insert shape enables turning both towards as well as away from the spindle, both cutting edges of the insert get utilized, substantially increasing the tool life. Additionally, with the chip thinning calculations, substantially higher feeds can be achieved, especially when the insert is feeding away from spindle.

To increase their use for steel turning applications across the automotive, energy and general engineering sectors, the upgrade includes more insert shapes for each grade. Having access to the correct insert shape is vital for effective finishing and roughing operations, and the insert shape should be selected relative to the entering angle accessibility required of the tool.

High tool life is achieved thru WEP10C coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain. The combination of edge preparation and grade also ensures dimensional stability over long periods of time, which boosts productivity in mass productionn

Depending on the application, the stainless steel adjusting screws are available in a variety of thread diameters and lengths and can be optimally fastened to the production machine in combination with bearing blocks GN 828 from Winco. Once the optimal setting has been found, the adjusting screw can be locked in place with a stainless steel knurled nut GN 827.1 designed specifically for this purpose. The bearing blocks are made of matte, smoothly polished aluminum which can be mounted from above or from the front.

TungBore-Mini is a multifunctional drilling and turning tool line that integrates the capabilities of drilling, OD, and ID turning tools. Its unique XOMU insert features an innovative geometry incorporating a large inclination angle on the cutting edge that produces light cutting, compared with standard ISO positive turning inserts that are typically used for ID turning or boring operations. In addition, TungBore-Mini's insert and pocket have a dovetail interlocking design providing better insert clamping and stability than standard screw-down insert clamping, ensuring process security during various applications.

When paired with an EIB 5211 sensor box, these new RCN encoders will transfer the temperature of the encoder and a direct-drive motor to the control in use. This gives the user the ability to push the system to its thermal load limits which in turn increases production and cost efficiency.

What is takes to turn the hardest metals.

Two new grades have been added to TungCut to enhance its capacity in exotic materials: AH8005 insert grade, featuring strong coating adherence to its carbide substrate, eliminates notch wear that typically occurs during the machining of heat-resistant superalloys (HRSAs). New geometries include DGS inserts with 0.05 mm and 0.10 mm (.0002″ and .0004″) corner radii. These sharp cornered inserts allow lighter cutting and precision grooving/ parting-off of small parts advantageous in Swiss machine applications.
