    Vertical CNC Milling Machine XK7136

    Elongated parts are the reason this machine exists. A 1250 mm table and 860 mm of X travel take long plates, rails and bases in a single setup, while a servo-driven Taiwan spindle, hardened box ways and pre-loaded ball screws keep the reversal points clean. Standard control functions cover line and arc interpolation, multi-point drilling and tapping, and a 16-station umbrella magazine can be added for multi-tool work.

    Overview

    Long-Table Vertical Milling for Elongated Parts

    Not every shop needs a bigger machine — many need a longer one. Three features make this mill the natural choice for long, narrow parts.

    Long Table, Long Travel

    A 1250 mm table with 860 mm of X travel lets long plates and rails be machined end to end without repositioning and re-datuming.

    No Reverse Backlash

    Pre-loaded ball screws remove the play that would otherwise show up as a lost move whenever an axis changes direction.

    Servo Spindle

    A servo spindle motor and drive with a Taiwan spindle unit running to 10,000 rpm, sized for both milling and drilling duty.

    Table Length Against Travel: What Fits

    Table length, travel and load together decide the largest part the machine will actually take, and how much of it can be reached in one setup.

    Short, thick partsUp to 860 × 450 mmFully covered by X and Y travel in one setup
    Long plates and railsUp to 1250 mm longFull length clamped on the table; long features reached without moving the part
    Tall partsUp to 600 mm above the tableSpindle nose clearance runs from 100 to 600 mm
    Rotary workUp to 460 kg with the rotary axisFourth axis indexes faces or turns cylindrical features
    Heavy partsUp to 460 kg on the tableMachined on hardened box ways for rigidity in the cut

    The capacities above are derived from the datasheet travel, table and load figures to help you size a part; they describe reach and support, not a guaranteed machining result. Send us the part and we will confirm the setup.

    Two points from the datasheet are noted rather than reproduced literally. The cutting feed row prints the unit as m/min against a value of 1–6000, which is read as a millimetre per minute range. A second dimension figure appears in the datasheet as 3000 × 2300 × 25500 mm; the dimensions above follow the machine outline used throughout the same table.

    Drive Train

    Pre-Tensioned Screws, No Reverse Backlash

    Four steps describe what happens at every direction change, and why it matters for tolerance.

    01

    Pre-Loaded Screw

    The ball screw is assembled with pre-load, so there is no free play between screw and nut to lose a move.

    02

    Clean Reversal

    When the axis reverses, the commanded position is reached immediately, with no dead band at the turn.

    03

    Accurate Bores

    Bores, pockets and shoulders come out round and to size instead of showing a witness mark at the reversal point.

    04

    Repeatable Batch

    Every part in the batch reverses at the same place, so the tolerance holds across the run, not just on the first part.

    A

    Line and Arc Interpolation

    Finish milling of straight and curved profiles at any angle is covered by the standard control functions.

    B

    Multi-Point Drilling and Tapping

    Hole patterns and tapped threads are programmed as cycles, so the umbrella magazine can run them in sequence.

    C

    Four-Axis Control

    A fourth axis can be fitted so cylindrical and multi-face work is machined without a second setup.

    Applications

    Elongated Parts and Multi-Hole Plates

    The jobs that reward a 1250 mm table and a backlash-free axis.

    01

    Long Plates & Rails

    Base plates, rails and guide bars machined along their full length without repositioning.

    02

    Multi-Hole Plates

    Plates with dense hole and thread patterns produced with program cycles rather than manual indexing.

    03

    Jigs & Fixtures

    Long fixture bodies and tooling plates milled and drilled from one datum on one table.

    04

    Machine Components

    Shafts, spacers and brackets for machine builders, run in small batches with the umbrella tool set.

    05

    Mould & Die Plates

    Long mould and die plates where reversal accuracy decides whether bores stay on position.

    06

    General Precision Milling

    Job-shop work where the part is long rather than heavy, and the table length is the deciding factor.

    Vertical CNC Milling Machine XK7136 Questions

    The difference is table length and travel. The XK7136 carries a 1250 mm table with 860 mm of X travel, against 1000 mm and 630 mm on the XH7132, so it accepts longer parts without repositioning. The spindle is a servo-driven Taiwan unit running up to 10,000 rpm, and a 16-station umbrella magazine is available as an option.

    When an axis reverses direction, any free play in the screw and nut shows up as a lost move, which is what causes witness marks and out-of-tolerance bores. The XK7136 uses pre-loaded ball screws that eliminate that play, so the axis returns to exactly where the control commanded and reversal points stay clean.

    Yes. The CNC control supports line and arc interpolation at any angle for contour milling, together with multi-point drilling and tapping cycles. With the optional 16-station umbrella magazine, a part sequence can run from spot drilling through tapping and on to profile milling without an operator changing tools by hand.

    Positioning accuracy is plus or minus 0.008 mm with plus or minus 0.005 mm repeatability on a 300 kg table with a 460 kg load rating, and the rapid traverse is 20 m/min on all three axes. The datasheet prints the cutting feed range as 1 to 6000 with the unit shown as m/min, which is read here as a millimetre per minute range.

    The bed is cast using an advanced process and then aged to relieve internal stress, meeting the applicable national standard for the casting. Aged iron holds its shape, so the machine's geometry stays stable over long service instead of moving as the casting relaxes in the first years of use.

    Standard builds ship in 15 to 30 working days after deposit, with customised spindle or control configurations taking 30 to 45 working days. English manuals, parameter files, live video commissioning and operator training are included, along with lifetime remote technical support. Volume terms are agreed per order.
