Machining (CNC)

Vollmer of America's CHD270 is a sharpening machine with 8 CNC-controlled axes and a measurement device, and it's intended for the automatic machining of carbide-tipped circular saw blades with various diameters and tooth geometries on face and top. 

The use of carbide- or cermet-tipped thin-kerf metal circular saws allows for high feed rates, low machining forces and thin saw kerfs—all of which reduces energy consumption and saves resources, according to Vollmer of America, which specializes in grinding and erosion machines, and develops sharpening machines such as the CM 200/300 and the CMF 200/300.

Intended for hook and clearance surfaces of carbide-tipped saw blades, the CHP 840 and 1300 universal sharpening machines with four CNC-controlled axes are suitable for the complete machining of all commonly found tooth geometries, according to Vollmer of America.

With greater scope in terms of its travel capabilities, the new Vgrind 360 is able to machine tools up to a diameter of 200mm, depending on the geometry. Just like its predecessor, the Vgrind 160, the same effective kinematics with two vertical spindles allow for multi-level machining.

The Vollmer eroding machine QXD 250 makes it possible for tool manufacturers to process more than 30 percent more PCD cutters in the same amount of time as has been the case up to now. This milestone in production is made possible by the generator technology Vpulse EDM, which sets the eroding beat at the heart of the QXD 250.

Hardinge announces the introduction of a hydraulically operated steady rest for its Conquest H51 CNC Turning Center. This new attachment is the Forkardt SRFN1 compact steady rest and is the ideal tool to support long workpieces without distorting or deflecting the part.

The SCHUNK TENDOturn utilizes a sealed hydraulic system which allows for fast and accurate tool changes. Users benefit from the advantages of the innovative hydraulic expansion toolholder technology, even with applications on lathes and milling centers.

DATRON Dynamics Inc. offers the DATRON neo compact CNC milling machine – the latest addition to the company’s line of high-speed machining systems. Designed from the ground up to deliver a productive, in-office machining solution that improves and accelerates today’s engineering workflow, the DATRON neo reportedly offers simple, clean operation and easy post-processing.

Dillon Chuck Jaws announces a new line Air Chuck Jaws including both Style M and Style R, such as those often machined using air chucks. CNC-machined for accuracy, the pins serve as a locator and allow precise repeatability plus fast installation.

Okuma’s new GA26W high speed, compact grinder is now equipped with the intelligent OSP-P300G CNC. Okuma’s open architecture OSP-P control runs on a Windows-based platform and fully integrates the machine, motors, drives and encoders, allowing for enhanced machine performance and true customization to suit particular machining needs.
