GOODWAY HIGH SPEED CUTTING SERIES

Please contact GOODWAY for detailed information.

Equipped with an optional live tooling turret, C-axis, Y-axis and sub-spindle and other advanced features allows GLS-2800/3300 can work on turning, milling, drilling, tapping and off-center milling tasks. The machining capability equals the integration of turning center and machining center, which significantly lowers machining cycle time and manpower, and also prevent accuracy error of switching work-piece to another machine.

SUPER RIGID STRUCTURE

Major structural components have been combined into one solid platform. The low center of gravity 30° slant bed design provides the most rigid foundation possible for the headstock, turret, and tailstock.

Built to withstand years and years of rigorous high production turning, the heavily ribbed, one-piece, thermally balanced bed and casting parts are of "MEEHANITE" casting, which can provide more efficient anti-damping and decrease lower deformation to allow much longer lasting and stand out among others.

All casting structure are detected by using Finite Element Analysis ( FEA ) to optimize the intensity, which can efficiently lower the deformation and strengthen the machine rigidity to ensure stable positioning and repeatability accuracy.

X / Z axes adopt the higher level FANUC αi series absolute servo motor that can provide rapid acceleration/deceleration and powerful thrust, which can efficiently lower the machining cycle time.

C3 class hardened and precision ground ball screws ensure the highest accuracy and durability possible.
1. Ball screws are through per-compaction to eliminate backlash.
2. Ball screws are through precise detection to ensure the parallelism with linear guide ways.

X & Z axes utilize high performance ball type linear guide way design which provides high precision high speed and low abrasion advantages. ( Roller type linear guide ways are available for option )

ULTIMATE TURNING POWER

The heavy-duty headstock is one-piece casting reinforced with heat dispensing fins, which can fasten heat radiation, minimize thermal displacement and lower accuracy error of thermal deformation.

P4 grade ( Class 7 ) super-high precision bearings are directly assembled for maximum level of support and precision. Bearing configuration adopts optimal 2-point support design for heavy-duty cutting with stable performance and long term high accuracy durability.

Specialized high performance V-type belt driven spindle motor can lower the effects of heat generated by motor. Pulley ratios has been adjusted to tune the motor's maximum speed to match the spindle's maximum speed, which result in full output at the lowest speed and maximize torque.

ADVANCED TURRET TECHNOLOGY

Heavy load servo motor tool indexing system provides 10 or 12-station turret with a 0.3 second indexing time.

High precision curvic couplings with large diameter Ø 250 mm ( 9.84" ) positioning tool plate. With 6,400 kg ( 14,100 lb ) clamping force, it makes sure the rigidity of turret in any machining conditions.

The curvic couplings provide auto-centering, auto-clean and a large contact area which are designed to distinct from traditional couplings.

SUPER RIGID TAILSTOCK

Programmable base tailstock can efficiently achieve tough machining tasks, and it has been simplified through use of custom software interface. Z-axis carriage automatically locks on to the base of the tailstock and drags it to the desired position.

The adjustment of the quill ( MT#4 ) is programmable and thrust can be adjusted by hydraulic.

Core components such as spindles, turrets, tailstocks are precisely developed by GOODWAY in a constantly temperature controlled A/C system to achieve the strict accuracy requirements and the best quality.。

POWERFUL LIVE TOOLING TURRETS

Super rigid 3-piece curvic coupling design, turret can remain the same place during indexing to achieve the faster indexing.

The 12-station GOODWAY live tooling turret offers 12 stations available for live tooling ( live tooling tools rotate in working position only ) and features a non-lifting turret disk.

With the latest technology, live tooling is driven by an AC servo motor to provide ample power, in the form of torque. Now, even the toughest of jobs may be tackled without a sweat.

HIGH PRECISE C-AXIS

C-axis adopts super rigid Cf-axis with disk brake system, and with the FANUC servo motor generating 240 Nm ( cont. ) of torque it offers excellent surface finishes and accuracy. Plus, dynamic accuracy is within ± 0.02º even under heavy cutting condition.

BACK-END MACHINING CAPABILITY

All series could select the optional sub-spindle to machine the back-end after receiving the part. Ø 51 mm bar capacity adopts 8" chuck featuring ejector, which allow the finished parts can smoothly drop on parts catcher successfully. All the processes from loading the parts can all be done in one machine without a pause.

Automatic part transfer of work piece from main spindle to sub-spindle saves manpower and cycle time, while reducing accuracy lost, which will occur if manually handling the part from machine to machine.。

The sub-spindle configuration is also ideal for machining long work pieces such as small diameter shafts. Both ends of the work piece can be supported by the main and sub spindles, allowing the middle section(s) to be accurately machined.。

Sub-spindle can be controlled by Cs-axis to achieve back-end machining, which allows conveniently operating, fast positioning, and higher accuracy.

Z2-axis adopts high performance linear guide way design, which is driven by FANUC direct driven motor, provides the optimal axial accuracy.

Y-AXIS CONTROL CAPABILITY

The optional Y-axis control can achieve X, Y, Z, C axes simultaneously machining, which allow the series can work on Y-axis 100 mm ( 3.93" ) off-center milling ( off-center ± 50 mm ( 1.96" ) ) , drilling, and tapping as well as improving the machining accuracy from a regular 3 axes simultaneously machining processes.

The fictitious axis and X-axis saddle adopt 30º included angle design that efficiently lower the center of gravity, and lighten the Y-axis mechanism loads. Meanwhile, the center of gravity of turret lays on the proper range of saddle to make sure the overall structural rigidity.
