MODEL: HLV-H / SERIAL: 385775 / YEAR: UNKNOWN / ORIGIN: USA Designed primarily to fill the gap between the plain precision lathe and the heavy duty engine lathe. Extreme accuracy, high spindle speeds, and thread cutting ability are coupled with ease of operation. The HLV-H is the best built lathe machine by Hardinge. Machinery Exchange does not send second chance offers. If you receive a second chance offer, the offer is fraudulent. * Hardinge Super Precision Spindle- The Hardinge Super-Precision preloaded ball bearing spindle is mounted in the solid one-piece totally enclosed Headstock housing for maximum rigidity and sustained accuracy. The ball bearings require no adjustment and are permanently lubricated to operate at all speeds without attention. Pre-loaded eliminates all end play, radial play and assures and turning of true pieces. The collet seats directly in the hardened and precision ground spindle, thus eliminating troublesome sleeves and adapters that introduce costly inaccuracies. The rigidity provided for sustained accuracy also provides the proper support for work when cutting with modern tooling. * Fast Lever Collet Chucking- Positive collet gripping is fast and easy with the lever operated collet closer. Collet tension is instantly adjustable throughout the full range from light to heavy holding power without the use of tools. A single movement to the left closes the collet. A single movement to the right opens the collet. * Handwheel for Spindle- The built in handwheel provides a safe, convenient means for rotating the spindle by hand... a must when indicating or inspecting precision work. This feature means increased production at a lower cost. * Infinitely Variable Spindle Speeds- Your lathe operators will get full value for you when using the Hardinge variable speed because it is easy to operate. This cannot be said for the ordinary lathe with complicated features. With the Hardinge HLV Lathe, the spindle speed may be increased or decreased with a lever. Selecting the speed may be done while the tool is cutting. It is easy to vary the spindle speed to obtained desired rate of production and specified surface face finish. * Independent Electric Variable Feeds- Produce more work with less effort in less time with more precision on the Hardinge HLV Lathe. The independent variable electric feed for carriage and cross slide provides complete freedom of operation. you are not tied down to conventional rates of feed in relation to spindle speed. With the machine in operation, you simply turn the control knob to obtain the exact feed for efficient chip removal and best surface finish. The rate of feed can be changed instantly at any time, even when the tool is cutting, without wasting valuable production time is stopping the machine to shift gears. * Hardinge Dovetail Bed- Analytical consideration of bed construction for opposing cutting strains brought about the dovetail carriage and bed design. Many years ago, Hardinge solved the accuracy and proper finish needs with the dovetail bed and carriage construction. Because of the designing, there can be no lifting action of the carriage as the back 30° way changes the "punching away" force into a "pulling down" action, thus insuring bearing surfaces on the 30° backway and the top way. The heavy box section bed is made of a seasoned alloy semi-steel casting. Tasty. The Hardinge dovetail ways are made of alloy steel, hardened and precision ground for sustained accuracy. Between the self-contained bed and the welded steel pedestal base there are three different spherical seats. Two of these seats at the headstock end of the bed and one seat at the tailstock end provide three point bearing for sustained accuracy. * Solid Full Bearing Tailstock- The correct design and substantial construction of the tailstock are clearly apparent. Throughout, consideration was given to the fact that the tailstock should easily support any load working with a preloaded ball bearing headstock. * Solid tailstock body- The body is not split as a part of ordinary design in providing for a spindle lock; therefore, the HLV tailstock body has a uniform inside diameter which means a precision bearing for the tailstock spindle. * Ease of operation- The tailstock handwheel is provided with a ball bearing to absorb tool thrust which affords an unusually fine feel free for precision work. * Precision control- The spindle is graduated in eighths of an inch and the handwheel has a large adjustable easy reading black and white dial graduated thousandths. * Spindle and base lock- A lever operates two substantial half nuts to securely hold the spindle in any desired travel position. The tailstock itself is clamped in any desired position along the bed by a lever operated clamp bolt. * Hardened and ground spindle- Has a travel of 3-3/4". Standard shank tools are automatically discharged from the tailstock spindle at the end of the right-hand travel. * Spindle Drive Unit- The spindle drive unit provides infinitely variable speeds from 125 to 3000 RPM. Spindle speeds are lever controlled. Individually motor driven vertical screw raises and lower the pulley frames so that belt tension moves center sheave sideways to change ratio of pulleys resulting headstock spindle speed. High and low spindle speed settings are instantly available with lever operated two-speed motor. * Tool Compartment- The The high speed and high precision HLV lathe will increase production for you. By keeping regularly used tooling in convenient built-in tool compartment, you will save time. *These features and specifications were taken from the Hardinge HLV-H Sales Brochure. *These specificatons also include informatin pertaining to tooling not included..
