How much does the JTEKT GS200H cost?

Price estimate

Uncertain

We do not have a price for the JTEKT GS200H that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The JTEKT GS200H is a gear skiving center built on a horizontal machining center: one machine that turns, mills, drills, bores and skives gear teeth in a single setup. It takes workpieces up to 20.7 in (526 mm) in swing diameter and has travels of 18.5 in (470 mm) in X, 14.2 in (361 mm) in Y and 24.2 in (615 mm) in Z.

Skiving cuts teeth with a rotating tool that is synchronised with the rotating workpiece. Internal gears, which are awkward to hob, are a typical use. Everything depends on how exactly the two rotations stay in phase. JTEKT describes a synchronous control system that coordinates the tool and workpiece spindles, real-time synchronization between the C-axis and spindle rotation, and pitch accuracy under 8 µm.

The tool spindle is a #50 taper unit, listed in the table as BT50 with a maximum speed of 6,000 rpm. JTEKT gives its output as up to 30 kW short-time and 25 kW continuous. The work is carried on a trunnion-type rotary table, and the linear axes run on roller-type linear guides at a rapid feedrate of 1,889 ipm (48 m/min).

Tool storage is 8, with a 2.4 sec tool change time. That is a small magazine by machining-center standards. It suits a process that needs a skiving cutter, a few turning and boring tools and a drill, and it rules the machine out as a general-purpose horizontal. The reason to buy it is process consolidation: bore, faces and teeth are cut without unclamping, so the gear's concentricity does not depend on a second chucking. Standard floor space is 94.5 × 118 × 123 in (2,400 × 2,997 × 3,124 mm) in width, length and height.

Strengths & Limitations

Strengths

Turning, milling, drilling, boring and gear skiving in one setup, per JTEKT's description
BT50 spindle with a maximum speed of 6,000 rpm and up to 30 kW short-time output
Workpiece swing up to 20.7 in (526 mm)
Synchronous control of tool and workpiece spindles, with pitch accuracy under 8 µm stated by JTEKT
2.4 sec tool change time and 1,889 ipm (48 m/min) rapid feedrate

Limitations

Tool storage is 8, far fewer than a general-purpose horizontal machining center
Y travel is 14.2 in (361 mm) and X is 18.5 in (470 mm), so the machine is limited to gear-sized parts
The table gives no module range, gear width or workpiece weight limit
Table speed and torque of the rotary axis are not published

Best For

Internal and external gears up to 20.7 in (526 mm) in diameter Ring gears and gear housings finished in one clamping Replacing separate turning, shaping and drilling operations on gear parts Production of gears where bore-to-tooth concentricity is critical

Frequently Asked Questions

01 What does the GS200H do that a normal machining center does not?

It skives gear teeth. JTEKT describes the GS Series as a multitasking horizontal machining center equipped with a gear skiving function, integrating turning, milling, drilling, boring and gear skiving on one platform. The synchronous control system keeps the cutter and the workpiece rotation in phase, which is what generates the tooth form.

02 How large a gear can the GS200H machine?

The maximum workpiece swing is 20.7 in (526 mm) in diameter. Axis travels are 18.5 in (470 mm) in X, 14.2 in (361 mm) in Y and 24.2 in (615 mm) in Z. The specification table does not state a maximum module, face width or workpiece weight, so those have to be confirmed for a given gear.

03 What spindle does the GS200H have?

A BT50 spindle with a maximum speed of 6,000 rpm. JTEKT calls it a #50 taper high-rigidity spindle for large-size gear skiving and heavy-duty cutting, with output up to 30 kW short-time and 25 kW continuous.

04 How many tools does it carry?

8, with a tool change time of 2.4 sec. That is enough for a dedicated gear process and not for general machining with a broad tool list. Plan the operation sequence around those eight positions.

05 How much floor space does the GS200H need?

The standard floor space is listed as 94.5 × 118 × 123 in (2,400 × 2,997 × 3,124 mm), given as width, length and height. Machine weight and power supply are not on the product page.
