数控专业英语1) In a typical NC system the numerical data that is required for producinga part is maintained on a punched tape and is called the part program. The part program is arranged in the form of blocks of information, where each block contains the numerical data required to produce one segment of the work-piece. The punched tape is moved forward by one block each time the cutting of a segment is completed. The block contains, in coded form, all the information needed for processing a segment of thework-piece.2) Standard Series VMC 8030It doesn’t matter if you are cutting steel or aluminum, this machine has all you need to rough-out material fast then execute final passes for smooth and accurate finish parts.The work envelope is 80”x30”x30” in X, Y and Z-axes. Optional extended Z travels are available should your applications demand.Large, Long PartsLarge and long parts are easily loaded onto the table from the front or side doors of this agile 18,000-pound VMC.10,000 RPM, 22.5 HP SpindleA standard 10,000 RPM 22.5 HP spindle with automatic mechanical HI/LO shifting delivers a wide range of impressive metal cutting power.Box Way ConstructionBox Way construction is utilized to provide the needed vibration dampening when high torque cutting is done at low spindle speeds or high horsepower cutting is done at high spindle speeds.21 Station Tool ChangerA 21 station geneva style tool changer is standard with an option of 30 tools.1) One of the objectives of CNC systems is to replace as much of the conventional NC hardware with software as possible and to simplify the remaining hardware. The software of a CNC system consists of at least three major programs: a part program, a service program, and a control program. The part program contains a description of the geometry. The serviceprogram is used to check, edit, and correct the part program. The control program accepts the part program as input data and produces signals to drive the axes of motion.2) Improved accuracy at higher speeds.The HPC-1250XTb combines Cincinnati Machine’s proven horizontal machining platform with a unique, polygon spindle bar to provide advanced part accuracy and high-torque machining. The shape of our spindle bar also insures superior rigidity, performance and helps increase the life of your machine. The new carrier design of the machine is based on a Cincinnati Lamb family of proven bar-type carriers.With a 5-inch diameter bar, the HPC-1250XTb provides improved access for large prismatic and box-like structures. The machine also utilizes dual ball screws for precise, radial and axial positioning of the bar at the work piece. A wide variety of options are available in the HPC-1250XTb, including pallet storage, tool storage, and cell configurations.Basic Specifications:X-Axis 86.6" (2200mm)Y-Axis 57.1" (1450mm)Z-Axis 56.1" (1425mm)Spindle4000 rpmSpeedSpindle#50 V-flangeTaper1) The concept of a machining center is to bring the machine to the work. In recent years, however, the term machining center has come to be associated almost exclusively with a single machine, usually incorporating automatic tool changing, a rotary table which facilitates circular machining, and one or two integral worktables. Such a machine is usually designed to perform operations on at least four and sometimes five surfaces. There are some machining centers with automatic tool changes in vertical and horizontal configurations. A typical machining center may use 50 or more tools.2) Vertical Machining Centers●Program Path Accuracy 0.0002" (0.005mm)●Spindle Speeds Up to 12,000 RPM●Contouring●Rates 200+IPM (5080+mm PM)●Spindle Horsepower (continuous) from 25 to 50HP (18 to 37KW)New Vertical Machining CentersConfigured to meet the high feed, high speed contouring needs of the mold and die industry, Kingsbury's NEW double column traveling table Vertical Machining Centers feature a unique two speed range spindle combined with contour control and program path accuracy that ensures remarkably productive roughing and finishing on the same machine. Our power-curve design ensures high horsepower at low and high RPM for outstanding super-finish capabilities on complicated molds and dies.The VMC 600 features◆Two spindles to choose from:24 HP at 250 RPM with 48 HP above 500 RPM15 HP at 250 RPM with 30 HP above 500 RPM◆Two speed ranges for each spindle: 0-1500 RPM and 0-12,000 RPM◆CAT 50V flange or HSK spindle tapers◆High Precision Contour Control packa ge HPCC◆64 bit RISC Processor with NURBS interpolation◆0.0002" (0.005mm) Path accuracy◆0.00002" Scale resolution (0.5 micron)◆Up to 146" (3.7m) x 102Ó (2.6m) X/Y Travel1) Manual tape programming is executed by part programmers. First they have to determine the machining parameters and the optional sequence of operations to be performed. Based on this sequence, they calculated the tool path and write a manuscript. Each line of the manuscript, which is referred to as a block, contains the required data for transferring the cutting tool from one point to the next one, including all machining instructions that should be executed either at the point or along the path between the points.2) A vertical, spindle taper No.30 and column-moving CNC turret machining centerFeatures●The simple construction allows lower costs and excellent durability.●Six tools are standard and 8 tools are optional can be mounted●Attaching the multi-axis attachment can shorten the machining time.●Pallet changes using the turn table is alsoavailable.Application● Gear cases● Oil pump cases● HDD chassis etc.1) Never attempt to machine a work-piece without first checking the operation of the machine. Before starting a production run, ensure that the machine is operating correctly by performing a trial run, for example, the single block, feed-rate override, or machine lock function or by operating the machine with neither a tool nor work-piece mounted. Failure to confirm the correct operation of the machine may result in the machine behaving unexpectedly, possibly causing damage to the work-piece and/or machine itself, or injury to the user.。
