Course 3: Cylindrical Grinding

Monday, November 2, 2020

 

Course 4: Diamond Dressing

Monday, November 9, 2020

Facts: online using Zoom • one day: 9:00 a.m. – 3:00 p.m. CST • attendance limited • opportunity for questions • focused on practical aspects to help you improve your operations now.

 

Goal: Give attendees a thorough, practical understanding of the subject, focused on key points and tools that enable them to make improvements immediately.

 

Why? For twenty years, Dr. Badger’s courses and presentations have been well known for being engaging, easy-to-understand and enormously practical. Because of Covid, he’s now offering them online in short, one-day modules. They’re a great way to drastically improve your grinding operations with very little investment.

 

Cost: US $395 – $495.

 

Includes: Handouts of course material in pdf format and The Grinder’s Toolbox program for choosing optimum parameters and speeds & feeds.

Course 1. Cooling

Goal:

 

 

 

 

Cost:

 

Topics:

 

 

 

 

 

 

 

Included:

 

 

Note:

Attendees come out with an understanding of how to achieve excellent coolant application in grinding, including when good cooling is necessary and when it can actually be harmful. In most applications, attendees will learn how to modify their existing coolant system in a few hours to reduce temperatures, reduce loading, extend wheel life and reduce or eliminate visible oxidation burn.

 

US$ 395

 

When do you need good cooling? When don’t you? • When can good cooling actually cause problems? • Pressure? Flowrate? Aim? What is most important? • Nozzles: What are my options? Can I make my own? • Crimped-down metal tubes: Quick, easy & effective • Coolant hydroplaning, cause of taper, other problems • Cleaning nozzles: Are they worth it? Common mistakes; when to use; how to use • Using The Grinder’s Toolbox to create an effective cooling system • Application for specific operations: creep-feed for the aerospace industry, flute grinding in tooling, cylindrical grinding, camshaft grinding, crankshaft grinding, bearing grinding, centerless grinding.

 

1. The Grinder’s Toolbox Cooling Module, emailed to attendees.

2. Handouts, emailed to attendees in pdf format.

 

The course covers coolant application, it does not cover coolant chemistries.

Course 2. Carbide grinding

Goal:

 

 

Cost:

 

Topics:

 

 

 

 

 

 

 

Included:

Give attendees a thorough understanding of the unique aspects of carbide grinding, allowing them to increase feedrates, reduce wheel wear and cope with loading.

 

US$ 395

 

Mechanisms: how carbide is different • Wheel loading: How do cope with it • Sweet-spot & increasing feedrates • Sticking: common mistakes • Cleaning nozzles: Do they work? • Hybrid-bond G-force-style wheels, Paradigm metal-bond wheels: How to use them • Using aggressiveness to increase feedrates and reduce wheel wear • Evaluating wheels scientifically (rather than trial & error) • Wheel sticking: Do it right or don’t bother • Wheel truing: Why it’s taking you so long, how to fix that • Wheel balancing: Is it necessary? • Flute grinding of carbide: case studies • sawblade grinding of carbide: case studies • cylindrical grinding of carbide: case studies.

 

1. The Grinder’s Toolbox Surface Grinding Module, emailed to attendees.

2. The Grinder’s Toolbox Cylindrical Grinding Module, emailed to attendees.

3. Handouts, emailed to attendees in pdf format.

Course 3. Cylindrical Grinding

Goal:

 

 

 

Cost:

 

Topics:

 

 

 

 

 

 

 

 

 

Included:

 

 

 

Note:

Give attendees a thorough understanding of cylindrical-plunge grinding and cylindrical-traverse grinding, enabling them to increase feedrates, eliminate chatter, increase form-holding and deal with burning (particularly on problematic shoulders).

 

US$ 495

 

How cylindrical grinding is different • Shoulder grinding without a swivel, how to cope with burn • Shoulder grinding with a swivel, how to cope with burn • Finding the sweet spot, how to increase feedrates with it • Burn: most likely causes, changing speeds & feeds to eliminate it • Workpiece RPM for burn, for chatter, for wheel wear • Overlap Ratio in traverse, using it to drastically reduce cycle time in roughing • Barber Pole in cylindrical traverse • Barreling in cylindrical traverse • Bell-mouth/taper in cylindrical plunge • Improving cooling: What it helps, when it hurts • Lobing: How to reducing it via “integer values” • Self-excited chatter: Causes, how to eliminate it • Fishscale chatter: How to eliminate it • Using The Grinder’s Toolbox in cylindrical-plunge grinding • Using The Grinder’s Toolbox in cylindrical-traverse grinding.

 

1. The Grinder’s Toolbox Surface Grinding Module, emailed to attendees.

2. The Grinder’s Toolbox Cylindrical Grinding Module, emailed to attendees.

3. Handouts, emailed to attendees in pdf format.

 

The course does not cover centerless grinding or peel grinding.

Course 4. Diamond Dressing

Goal:

 

 

Cost:

 

Topics:

 

 

 

 

 

 

 

Included:

 

 

 

 

Note:

Give attendees a thorough understanding of diamond dressing – stationary, plunge-roll and diamond disc. Explain common mistakes and how incorrect dressing is a predominant cause of grinding burn.

 

US$ 395

 

Dressing, primary cause of grinding burn, how & why • Dressing depth, correct values • Velocity, diamond wear & overlap ratio, common mistakes • Single point, pitfalls, compared to blade, cluster, chisel, etc. • Wear spot, how it affects sharpness, transient nature • Diamond carat size • Rotary dressing speed • Ratio, sharp or dull, common mistakes • Plunge roll effective depth, common mistakes, especially in aerospace applications • Plunge roll dwell time • Traverse diamond disc, wear spot • Rotary dressing of CBN • Kamikaze attack angle • The Integer-Egg effect, cause of fish-scale chatter, straight-line chatter • Using The Grinder’s Toolbox to determine wheel sharpness and avoid wheel lobing.

 

1. The Grinder’s Toolbox Stationary-diamond Module, emailed to attendees.

2. The Grinder’s Toolbox Plunge-roll Module, emailed to attendees.

3. The Grinder’s Toolbox Diamond-disc Module, emailed to attendees.

4. Handouts, emailed to attendees in pdf format.

 

The course does not cover truing of superabrasive wheels with SiC/AlOx.
