Boring Toolholders & Boring Heads
|
The most successful manufacturers in the world invest in superior tooling because it is good for their bottom line. The precision and ruggedness of BIG KAISER boring heads deliver measurable performance advantages - significantly reducing finishing cost and cycle time.
The KAISER modular precision tool system is the solution for drilling, rough boring, finish boring,milling and tapping. Important customers are not only the machine-building, auto, and aircraft industries, but also machine tool manufacturers, tool & mold makers, and job shops that equip their machining centers with KAISER tools in order to offer the customers solutions according to their demands. |
BIG-PLUS®
|
It's a spindle system that provides dual contact between the spindle face and the flange face of BIG-PLUS® tooling.
Simply by switching holders, you can greatly increase tool rigidity, reduce runout and add significant productivity to your machining applications. |
BIG-PLUS® holders and spindles are manufactured to micron level specifications.
The unique tool holding technology increases surface contact with the tool holder, maximizing rigidity and clamping pressure. There is a significant advantage in tool life, accuracy and cutting capability when compared to standard tool holders. Because of the unique design, the system allows complete interchangeability between existing tooling and spindle systems. No shim kits or spindle face qualification is necessary.
The Benefits of BIG-PLUS® Do Not Stop There
When used with a BIG-PLUS® spindle, there is the additional benefit of contact between both taper and flange of the holder and spindle. This Dual Contact design further improves rigidity and accuracy, eliminating fluctuations in z-axis precision due to tool draw.

Milling Tools
|
The most successful manufacturers in the world invest in superior tooling because it is good for their bottom line. Greater precision, longer tool life and deceased downtime are just a few of the cost saving benefits of investing in premium tooling.
From the powerful Fullcut Mill and the super smooth Speed Finisher to the versatile C-Cutter Mini, our line of high quality milling tools delivers measurable performance advantages that drive down costs and maximize profits - guaranteed. We'll improve your most demanding applications, or we'll take back our products...no charge. |
Tapping Tools
BIG Kaiser offers two key products lines to meet your tapping needs.
|
The Mega Synchro Tapping Holder, available in 41 bodies and 45 tap holders, offers ideal projection lengths for any machine. It improves thread quality and tool life by reducing thrust loads caused by synchronization errors during rigid tapping.
The Drill Tapper is a unique system for drilling and tapping. This quick-change holder lets you exchange taps and drills in seconds, providing two operations with one stable head. |
Spindle Speeders
|
Boost the speed of your existing machining center up to 20,000 - 80,000 RPM with High Power Spindle and Air Power Spindle, spindle speeders from BIG Kaiser.
These units can be used on existing machining centers to provide dramatic enhancements to surface finish quality and extended tool life. In addition, continuous use of machine spindles at high revolutions can shorten the life span of your spindle due to excessive load on its motor and bearings. |
Spindle speeders provide all the performance benefits of a high speed spindle without the increase in load, greatly extending the life and performance of your machine.
Angle Heads
|
Get the most out of your current machining center with the simple, powerful addition of BIG Kaiser Angle Heads.
By allowing vertical, horizontal and angular operations without repositioning the workpiece, our Angle Heads dramatically increase both accuracy and productivity. Angle Heads leverage your current machine's capabilities - giving you the results of a brand new machine without the expense. |
Coolant Inducers
|
HI-Jet Holders introduce coolant capabilities to machine tools without coolant-through spindles.
HI-Jet Holders minimize overheating and distortion of workpieces and allows coolant-through cutting tools to provide faster metal removal rates by flushing chips out of the holes. With reduced heat generation, tool life is greatly extended. |

How To: KAISER Series 112 Radial Boring Bar Adjustment Options
"To get the greatest productivity and flexibility from the KAISER 112 boring system, we recommend replacing the fixed bar & insert holder with a radial adjustment bar & insert holder which keeps the bar at centerline at all times."

Choosing the right ER Collet Chuck Size
"We often get asked to spec out tooling packages for new CNC mills and one of the questions we encounter most, or should, is how do you select the right toolholder collet size for your companies applications? The real choice is in the size of the collet chuck itself. So several considerations should be reviewed…"

When Boring gets painful is it time to go digital? "Boring tools with a digital readout aren’t the standard in U.S. shops, but their use is growing.
Think about the number of digital equipment interfaces and interactions an operator has when machining."

Flexible 5-Axis Workholding Solutions Keep Spindles Running
"The benefits of 5-axis machines are greatest when workholding is based on the size and shape of the workpiece instead of the limitations of the table interface. By providing multiple workholding opportunities, Unilock users quickly integrate most workholding products and keep their machine spindles up and running."

Thinking about synchronous tapping to reduce CNC cycle time?
"One of the most common methods of tapping in use today on CNC machines is “rigid tapping” or “synchronous feed tapping.” A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory, a solid holder without any tension-compression can be used."

Unilock workholding for lean manufacturing
"To be competitive in today's market, all machines need efficient workpiece handling.
Efficient part loading systems are always included in the acquisition of high-volume manufacturing cells but all too often getting fixtures on and off the CNC milling machine is forgotten. In today's market, time is money."

I like end mills holders, why shouldn't I use them?
"We often run end mill "tests" to determine which one performs best. Obviously, our goal is to "win' the test and get more business for our manufacturer's. This is article is about one our "tricks" and it's also why represent both cutting tool manufacturers and rotary tool manufacturers. We want to insure that the products work together.

Increasing CNC Production throughput with Tool Presetting
"All too often, shops invest hundreds of thousands of dollars in a new machining center to increase production, when they could accomplish the same thing with existing machinery at a fraction of the cost. Many machines cut metal less than 50% of the time during working hours— even less in a flexible manufacturing environment where part runs are generally short."

Evaluating Toolholders for Wear & Fretting
"A worn out toolholder will not provide good accuracy and will quickly wear out your cutting tools. Worn tooling can also cause poor surface finish, and may even damage your spindle."
