Toolholders & Collets

Reaching deep inside a workpiece to drill holes can be a real bear. You've tried taper length and aircraft drills, but even those made of solid carbide are apt to wander when hanging out of the chuck unsupported.

BIG KAISER announces its HDC Straight Shank holder to the market, used for increased versatility. The slim design provides superior balance, concentricity and is suitable for reaching into confined areas.

Lexair's new Flex Grip closers are designed for versatility and efficiency, and they are proven to boost productivity for a variety of machining operations including 5-axis, rotary indexer and stationary applications. The manual/hydraulic closers are clamped through a screw pump with a spring return opening.

NT Tool's angle heads add a new cutting axis to existing machines, allowing you to machine from additional angles without the need for tilt tables. By building a new axis into the toolholder itself, machining plants can save greatly on setup costs and expensive investments in new machinery.

The compact, high-precision Quicktech S-32 ATM 9-axis, twin-spindle mill/turn center combines integral-motor main- and sub-spindles with a 190° B-axis milling head and a fast automatic toolchanger to maximize output of small, complex parts. Quicktech machines are distributed in North America exclusively by Absolute Machine Tools Inc.

If you are looking for product quality improvements that only an ultraprecision tooling spindle can provide, and also require the robustness of an industrial grade design, Precitech says the ASD-H25 and ASD-Cx high-speed air-bearing ultraprecision tooling spindles by Levicron are precisely what you need.

Thanks to their outstanding tool lives, fine surface finish and maximum concentricity, hydraulic chucks found their place in milling. And there is good reason since these chucks offer both continuous action of the cutting edge and excellent vibration-damping properties.

Seco has further expanded its selection of disc milling inserts and cutter bodies to meet customer demands for reliable, high performing cutters. With that, the company has introduced the 335.14 small-diameter exchangeable head system, 335.16 cutter for T-slot operations and cassette versions of its 335.25 cutter that incorporate round inserts.

Lexair's full-bore, fixed-length, self-contained collet chuck allows full-capacity spindle operation, due to elimination of the drawtube. When using the full bore chuck, spindle capacity is boosted as much as 30 percent, and clamping pressure is unaffected by centrifugal force, regardless of rpm, according to the company.

Collet pad top jaw systems from Dillon Manufacturing Inc. can convert through-hole chucks to hold small bar and tube stock. Collet pads can be changed quickly maximizing production time, and the jaws can be adapted to many styles of chucks, making them ideal for special purpose function machining.

BIG KAISER's Mega New Baby Chuck is now available up to 1"-dia. clamping for drills, reamers and finishing endmills with 0.00004" runout accuracy. The Mega New Baby Chuck is a high precision and multiple-purpose collet chuck system.

Heimatec Inc. now offers products from Tecnicrafts Industries, a manufacturer of collets and guide bushings for Swiss-type CNC Lathes. Tecnicrafts is an ISO 9001:2015-certified company, with its manufacturing plant in South India with state-of-the-art machine tools and 115 technicians.
