GSK CNC Equipment Co., Ltd.
GSK develops CNC systems, servo drives and motors from a Guangzhou business established in 1991. A June 2026 university visit describes its component processing, modular assembly and production checks. The GS catalogue adds practical machine-tool detail: separate feed and spindle motors, a no-bus GS-N connection, second-position feedback and model-specific current and braking tables.

Machine-tool control is the centre of GSK's company story.
The manufacturer's business extends from numerical control into its drives, motors and adjacent equipment.

Ownership restructuring
The company records its transition to a privately owned enterprise.[1]

University production visit
Students visit the Guangzhou operation on 2 June; the university publishes its account on 5 June.[3]
The machine-control business
The official overview names GSK CNC systems, AC servo drives and motors, and spindle drives and motors. Industrial robots, GSKAEz all-electric injection-moulding equipment, machine-tool retrofits and technical training form adjacent activities. This gives a buyer a specific machine-tool context for the GS range, including the relationship between the CNC, feed motors and spindle.[1]
A recent external visit follows the equipment from exhibits into the production workshop.
Guangzhou Software Institute reports observations at GSK's Huangpu operation, rather than a remote company-directory entry.
Products and production work
The visiting students first saw CNC-system exhibits and heard explanations of industrial control and servo technology. In the production workshop, the report describes precision component processing, modular assembly, core-process adjustment and quality-control activity. These are specific observations from the June 2026 visit and provide manufacturing context beyond the product catalogue.[3]
Engineering and technical training
The visit included direct questions to engineers about intelligent manufacturing, technical roles and the skills required for automation and CNC work. GSK's own business introduction separately lists high-skill training and machine-tool retrofit activities. For a retrofit buyer, those subjects connect the drive purchase to the practical work of programming, commissioning and operating a machine.[1][3]
A GS feed motor and a GS spindle motor are selected for different machine duties.
The catalogue separates synchronous servo motors from induction spindle motors and provides named combinations.

| Published combination | Motor duty | Motor reference | Matched drive |
|---|---|---|---|
| 80SJTA-M024C | Synchronous feed servo | 0.5 kW · 2.4 N·m · 2,000 r/min | GS2025T |
| 110SJT-M040D | Synchronous feed servo | 1.0 kW · 4 N·m · 2,500 r/min | GS2030T |
| ZJY182A-1.5BH | Induction spindle | 1.5 kW · 9.5 N·m · 1,500 rpm rated | GS3048Y / GS4048Y |
Motor type is visible in the model
The catalogue uses T for the synchronous servo-motor route and Y for the induction-motor route. Its family description gives 0.5–30 kW synchronous servo and 1.5–45 kW induction-spindle scope, with three-phase 220, 380 and 440 V alternatives. The illustrated packages above are specific catalogue combinations; the final motor, feedback and voltage code should remain together in the order.[4]
The nominal power-device code is different from rated drive output current.
Two separate parts of the catalogue explain the naming and the actual output ratings.
Read the rating table
The naming diagram labels its three-digit current field as the nominal current of the power component. For example, the GS2030 technical table gives 12 A rated output and 25.5 A maximum instantaneous output, while GS3048 gives 13 A and 28.3 A respectively. The numbers 030 and 048 therefore should not be presented as the drive's continuous output-current rating.[4]
Continuous duty and short peaks
The catalogue distinguishes rated output from maximum instantaneous output. Its overview also mentions two-to-three-times overload without stating a duration. VFDMatch recommends retaining the exact model's continuous current and asking for the applicable time/duty limit when checking a machining cycle, instead of adding an unsupported overload time to the family claim.[4]
GS-N uses pulse or analogue commands with separately identified position feedback.
The N code denotes no communication bus in the reviewed configuration.
Commands at the CNC connection
The GS-N technical spread describes D-SUB connectors, digital pulse and analogue-voltage commands, and incremental encoder feedback. Its pulse table gives a 1 MHz maximum for this no-bus route. This is more specific than the catalogue's general 4 M pulse headline, so an existing CNC retrofit should identify the actual drive route and command interface before using a frequency limit.[4]
Motor feedback and machine measurement
The model key distinguishes a configuration without the second feedback-input interface from one with both first and second interfaces. For feed servos, the second-position route accepts an incremental rotary encoder or linear scale; for spindle servos, the table identifies an indexing-signal interface. The catalogue's GS-N drawing connects a GSK980TD/MD CNC to feed drives, a spindle motor and its encoder, showing where these signals belong in the machine.[4]
Resistor arrangements depend on drive frame and spindle inertia.
The reviewed tables separate internal and external arrangements and distinguish load conditions.
Model-specific resistor scope
The smaller GS20 rows list internal braking resistance with optional external resistance, while the GS30/GS40 tables list external resistor selections. Those latter tables distinguish large/medium-inertia spindle applications from small-inertia applications. Some entries call for two identical resistors in parallel. Keep the specified resistance, power and quantity together when requesting a drive package.[4]
A complete machine-tool handover
VFDMatch recommends including the existing CNC, motor code, full GS interface/feedback code, supply, acceleration and stopping cycle in a retrofit enquiry. Add wiring drawings, matched resistor hardware, the homing/limit arrangement and tuning responsibility. The catalogue gives RXLG and RXFG resistor dimension routes, so the cabinet proposal can also retain the actual mounting space rather than treating braking hardware as an unspecified accessory.[4]

Buyer questions
Does GS2030 mean 30 A continuous output?
No. The reviewed catalogue labels the code as nominal power-component current; its GS2030 table gives 12 A rated output.
What does N identify in the reviewed GS model key?
It denotes the no-communication-bus route, using the documented pulse/analogue and feedback connections.
Is the second feedback interface identical for feed and spindle duties?
The catalogue describes incremental encoder/linear-scale feedback for feed servos and an indexing-signal interface for spindle servos.
Why does the braking-resistor proposal need spindle inertia?
The catalogue lists different external resistor selections for large/medium-inertia and small-inertia spindle applications, with parallel quantities on some models.
