Overview

What This Machine Does

The YB3150E hobs spur and helical gears and worm wheels, and it will cut by the climbing hobbing method as well as by conventional hobbing. Climb hobbing raises productivity because the hob enters at full chip and the cutting load falls through the pass, so the cycle is shorter on the same gear. Two features change what one operator can cover: a rapid traverse device on the hob slide, which cuts the air time between passes, and an automatic stop mechanism, which lets the machine finish a gear and shut down on its own. Together they are what allows several machines to be handled by one operator rather than one machine per person. Either axial or radial feed can be used, so worm wheel work is done properly rather than forced into an axial approach. A Siemens CNC system can be configured to customer requirement, adding drum gear and small taper bevel gear machining. The machine can also be heightened and lengthened to expand the machining range, and it is straightforward to operate and maintain.

Application

Where YB3150E Gear Hobbing Machine Earns Its Place

Problems It Solves

  • Conventional hobbing alone leaves productivity on the table that climb hobbing recovers
  • Slow hob slide return wastes machine time between passes
  • A machine that does not stop itself needs an operator watching it to the end of the gear
  • One operator per machine makes a gear cell expensive to staff
  • Drum and small taper bevel gears cannot be produced on a purely mechanical hobber
  • A fixed machine height limits the gear sizes a shop can take on

Who It Is For

  • Gear manufacturers running multiple hobbing machines
  • Transmission and gearbox producers
  • Subcontract gear cutters with mixed gear types
  • Manufacturers needing drum or small taper bevel gears
  • Distributors supplying production gear hobbing machines

Application Scenarios

  • Production hobbing of spur and helical gears where cycle time matters
  • Worm wheel cutting using radial feed
  • Multi-machine gear cells run by a single operator
  • Drum gear and small taper bevel gear work where the Siemens CNC is fitted
  • Shops needing a heightened or lengthened machine for larger gears
  • Unattended finishing of a gear using the automatic stop mechanism

Comparison

How It Compares With the Alternatives

Y3150K minitype gear hobberThe Y3150K covers the same basic gear types in a compact machine; the YB3150E adds climb hobbing rapid traverse and an automatic stop for multi-machine working
Y31125E gear hobbing machineThe Y31125E leads on wide bed rigidity and its ground copper indexing worm gear; the YB3150E leads on cycle time and unattended running
YB3180 gear hobbing machineThe YB3180 is the larger machine in the same family with a semi-automatic cycle and auto lubrication; choose by gear size
Conventional hobbing onlyClimb hobbing enters at full chip with load falling through the pass, which shortens the cycle on the same gear
Use Guide

Running the Machine

Step 1

Mount the hob and check run-out before setting the blank

Step 2

Set the blank in the workholding and confirm it runs true

Step 3

Choose conventional or climbing hobbing for the gear and material

Step 4

Select axial feed for spur and helical gears or radial feed for worm wheels

Step 5

Use the rapid traverse device to bring the hob slide into position

Step 6

Take a first cut at reduced depth and check the tooth form before continuing

Step 7

Let the automatic stop mechanism end the cycle and inspect the gear before starting the batch

FAQ

Questions About YB3150E Gear Hobbing Machine

What is climb hobbing and why does it matter?

In climb hobbing the hob enters at full chip thickness and the cutting load falls through the pass. It raises productivity on the same gear compared with conventional hobbing. This machine does both, so you choose per job.

Can one operator run several of these machines?

Yes, that is what the rapid traverse device on the hob slide and the automatic stop mechanism are for. The machine finishes the gear and shuts down on its own, so an operator can cover more than one machine.

Can it cut drum gears or small taper bevel gears?

With the Siemens CNC system configured, yes. Specify it when you enquire, as it is configured to customer requirement at build.

Can the machine be modified for larger gears?

It can be heightened and lengthened to expand the machining range. Send us the largest gear you need to cut and we will tell you whether a modified build covers it.

What gear quality can we expect?

That depends on the hob, the blank material and the setup as well as the machine. Send us your drawing with the quality grade required and we will confirm before you order.

Can it be built for our supply voltage?

Yes. Confirm your voltage phase and frequency at enquiry and the machine is wired for your market.

What are your trade and payment terms?

FOB CFR and CIF. Payment is 30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
