Large swing, big bore geared head lathes

The LA, LB, and LE Series Clausing Large swing extra heavy, big bore geared head lathes are designed for optimum performance and heavy stock removal, while providing the versatility required by a large range of industries. Ten models are available with up to 12创 spindle bores, swings of 26.75创, 29创, 33创, 43创, 50创, 54创, 58创, 63.6创, and 67.36创, with 60创 to 280创centers.

All Clausing large swing lathes offer features to ensure accuracy and reliability. For maximum rigidity, the carriage, apron, and the extra wide one-piece bed are Meehanite castings. The slideways, tailstock quill, spline shafts, pre-stressed bedways, and all gears are hardened and ground. The lathes offer a range of feeds--inch, metric, module, and diametric pitch threads can be cut by simply changing levers. The high torque 18-speed spindle is supported by precision taper roller bearings, and driven by a single speed drive motor equipped with and electromagnetic spindle brake. Clausing large swing lathes also feature automatic lubrication, full-length splash guard, four-position stop, four-way tool post, six-way rapid traverse, and a thread indicator and dual dials. A wide range of options is available including roller brackets, five-deg manual spindle indexing, quick change tool post, tailstock hydraulic quill and pushbutton pneumatic speed change.

The Fagor CNC 8055 TC control provides the operator with an interactive graphic interface that's easy to use. There's no need for any programming knowledge--any operator can take care of any need by keying in the machine conditions and the geometric part data. The Fagor control allows the operator to define cycles and determine the operating mode--jog, automatic, profiling--minimizing set-up times.

Multi-operation machining center

The KAM machining center offers ultra-rigid milling, drilling, tapping, grinding, and turning in vertical and horizontal orientations. Unlike machines that require the use of right angle or multi-axis heads, the KAM allows both milling and turning tools to be positioned from vertical to horizontal in two degree increments and clamped into position, providing an ultra rigid location. The milling spindle provides 30 continuous horsepower with speed ranges from 250-rpm to 4000-rpm. Optional moveable column or Y-axis. Standard ram spindle is designed for HSK100 tooling and provides both coolant and air through the spindle and tool.

Insert grades

Milling insert grade GC2030 is suited for austenitic and duplex stainless steels and other sticky materials, and GC2040 is targeted for extra abrasive ferritic and martensitic stainless steels, titanium-stabilized austenitic stainless steel, and pH steels. Both grades are available in roughing and finishing geometries, and work equally well whether wet or dry.

Power chucks

The PAF Series of 2+2 jaw power chucks are a closed center style with two separate clamping motions of opposing jaws, making them ideal for square or angular work. The chucks are available in sizes 10创, 12创, and 15创 with A Type spindle noses. The 10创 and 12创models have a 0.63 jaw stroke diameter. All models have high clamping forces. A double acting cylinder, offered by Pratt Burnerd America, is required for operation.

Servo actuators

The AR servo actuator offers a compact integrated design as the servo amplifier, servo driver, and controller are integrated into a single unit. It has a self-contained electronic gear that enables positioning data to be set easily without considering the machine's reduction gear ratio. The AR servo offers absolute and incremental encoders supported by the amplifier and a built-in brake control function which is synchronized with the actuator's on/off functions.

Gear shaper

The Gleason Pfauter GP 300 ES Gear Shaper can change over from spur to helical gears, or from one helix angle to another, without having to first change the guide to accommodate the new gear. Where conventional gear shapers use a mechanical or hydrostatic helical guide to create the E-axis spindle rotation that produces the required helix angle, the GP 300 ES uses a backlash-free direct drive under CNC control. Any helix angle within a wide range of stroke rates and length can be created by changing the CNC program.

Diamond burnishing tool

Toolholders on these diamond burnishing tools are offset so the diamond insert is on center. The tools produce mirror-like finishes on ferrous and nonferrous part surfaces, on manual or CNC turning machines. The tools are commonly used on shafts or faces of any diameter, and can also be applied to large bores. Cogsdill now offers a shorter tool for use where work length is restricted. The polished diamond insert can be changed easily, on some models without removing the tool from the machine.

Hardness testing

The LM-, and LV-series hardness testing systems feature two precision photoetched measuring lines, changeable field and aperture diaphragm, and dual leafspring indenter supports for centered indentations. The auto turret on the LM and LV series provides more precise centering by returning to the same spot every time. Both the LM and LV series are available in manual, semi-automatic, and automatic video/image analysis systems.
