GS200 - Series


Packed with industry leading technology and top quality components, the Goodway GS-200 series turning centers combine incredible power, strength, and speed to bring you The Ultimate Machining Power. These powerful maximum performance machines will easily accomplish the demanding turning applications of today and tomorrow. 2 bed lengths (utilizing the same advanced design) and 3 spindle sizes offer a total of 6 basic model configurations to suit your application. Furthermore, with available live tooling, C-axis, Y axis, and sub-spindle capabilities; milling, drilling, and front/back-end turning applications may be completed in one single machine.

30° slant-bed design provides smooth chip disposal and easier operator access. Stainless steel way covers and special steel wipers molded with industrial strength rubber are used for durability. Fully enclosed splashguards keep chips and coolant contained for a safe clean working environment. The auto lubrication system delivers metered amounts of lubrication to the slide ways, ball screws, and vital components. Distribution is automatically shut off during idling to prevent waste. An adjustable timer on the standard chip conveyor allows the operator to set operation intervals according to the amount of chips carried out of the machine. Thus, reducing coolant loss to a minimum.

 

Construction

 

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. By using Finite Element Methods (FEM), optimal reinforce ribbings are directly cast into the one-piece bed structure. Mechanical rigidity has been increased by more than 40% when compared to conventional designs. The GS-200 series is capable of performing super heavy-duty turning and maintain long-term super high-precision accuracy. More rigidity also means extended tool life.

 

Spindle

 

The heavy-duty head-stock i s of one-piece casting reinforced with heat dispensing fins. P4 grade (Class 7) super-high precision bearings are directly assembled for maximum level of support and precision. Bearing configuration is designed for super heavy-duty cutting with ultra-smooth performance and long term durability with a higher level of accuracy. Standard rigid tapping feature provides high-speed precision tapping without the use of floating tap holders. Set-up is easier and depth of thread more accurate, permitting maximum productivity for tapping operations.

 

Turret Technology

 

The super heavy-duty servo indexing turret features the newest non-lifting turret disk technology. Achieving 0.2 second indexing times for adjacent stations and 0.5 second for stations at the opposite end of the disk. Index movements are single step, without pauses, no matter how many stations are skipped.

 

Tool positioning

 

Standard spindle orientation feature allows the spindle to stop at desired programmed position. Useful in broaching and manual part loading  applications where a fixed spindle position is required.

 

C axis

 

The Cf-axis and disk brake system available on the GS-200 series provides the most rigid and powerful type of C-axis on the market today. In Cf-axis mode, a servo motor is engaged and drives the rotation of the spindle; engagement time is approximately 1 second. Working with the live tooling turret, the Cf-axis and disk brake system enables the machine to perform multiple tasks, such as drilling, tapping, and milling operations, including cylindrical a    nd polar coordinate interpolations (resembling a 4th-axis rotary table on a machining center).

 

Y axis

 

Y-axis control further enhances multi-tasking live tooling capabilities and improves various machining precision. High precision grooving and X-axis off-center drilling are enabled. On Y-axis equipped machines, the turret is mounted on a secondary 30 degrees wedge saddle on top of the X-axis slide. Both X & Y axes have extra wide hardened and ground box ways, which are directly formed onto the saddles during the casting process. They are precision machined and widely spaced for maximum strength.

 

B, C2 axes

 

The sub-spindle travels on the B-axis, which has extra wide hardened and ground box ways. The box ways are directly formed onto the machine bed during the casting process. They are precision machined and widely spaced for maximum strength. 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.
