Product Details

Product Overview

The YB200 Precision CNC Vertical Gear Hobbing Machine is designed for machining cylindrical spur and helical gears. It features a six-axis platform with coordinated machining capability, a maximum workpiece diameter of Ø200 mm and a maximum module of 6 mm.

Key Features

Japanese FANUC CNC system controlling the X, Y, Z, A, B and C servo axes.
High-rigidity machine bed, spindle-box slide and hob arbor.
High-precision, high-rigidity linear roller guideways.
Auxiliary locking mechanism on the tangential slide.
Hob-head swivel range of ±45° and maximum hob diameter of Ø130 mm.
Graphical operating interface and automatic programming functions are described in the supplied material; confirm software scope and options for the quoted machine.

Applications

Designed for cylindrical spur and helical gears. The supplied material states that Grade 6 accuracy to GB/T 10095-2001 can be achieved for gears with module ≤3 mm when suitable cutting parameters and hob accuracy are used. Actual results depend on the workpiece, tooling, setup and process conditions.

Configuration note: Confirm the final machine configuration, controller functions, accessories and process capability against the current quotation and acceptance documentation.

Frequently Asked Questions

I can provide drawings, material and blank specifications. Can you recommend the right machine and machining route?

Yes — that is exactly how we start. Send the drawing (PDF, DWG or STEP), material grade, blank dimensions, key tolerances and your target output. Our engineers review the part geometry and process, then recommend a machine model, fixture concept and machining route, together with an estimated cycle time. We reply with a written evaluation and quotation within 24 hours.

Can my part be completed in one setup? Which operations would need other equipment?

It depends on geometry, size and accuracy, so we answer this per part, not in general. After reviewing your drawing we reply in writing: which operations are completed in one clamping, which need a second operation or a different machine, and what the recommended process chain looks like. If a part genuinely needs two setups, we say so instead of promising one-setup results.

Are cutting tools, fixtures, bar feeder and CNC programs included?

They can all be included — the delivery scope is defined line by line in our quotation. A typical turnkey package covers the machine, fixtures designed for your parts, the tooling package, bar feeder integration and CAM programs for your parts, plus a recommended consumables list. If you prefer machine only, or want to keep your existing tooling, the scope is adjusted and every included and excluded item is listed before you sign.

How do you evaluate the machining time for my parts?

We build the process route first, then calculate cycle time from tool paths and cutting data, and cross-check it with CAM simulation. The estimated time per part is stated in the proposal. During trial cutting the actual cycle time is measured; the measured result — not the paper estimate — is the basis for acceptance, so the number you plan production around is a verified one.

Can you run trial cutting with my own material?

Yes, and we recommend it. You send material or blanks; after the machine, fixtures and programs are ready we machine your parts, record cutting parameters, cycle time and tool behaviour, and provide a trial report with measurement results, photos and video. The trial schedule is agreed with you in advance, so you can attend in person or follow it remotely.
