Optimize Machine Performance
QUALITY TOOL HOLDERS WITH THE NIKKEN ADVANTAGE
Quality tool holders optimize machine tool performance to produce quality parts that are within the desired specifications. Quality is in the process of manufacturing the tool holder – you’ll never regret choosing Lyndex-Nikken quality.
Nikken high quality brand tool holders have been patented in Japan and in many other countries. With unique features, they are used all over the world and have been proving their efficiency for years and years, providing users with benefits that help them stay ahead of their competition.
Sub Zero Treatment
Nikken performs a sub-zero treatment to its tooling. All tool holders are subject to ultra-low temperature treatment of -90° C after carburizing. This treatment removes residual austenite to form 100% martensite compositions to prevent deformation and deterioration over time – this illustrates the quality of Nikken tooling.
Taper Contact
Nikken guarantees 85% of the taper contact ratio. It allows concentricity, run-out accuracy, and stable machining, while also reducing damage to the machining center spindle and extending tool life. Strong rigidity between machine spindle and tool holder eliminates potential fretting corrosion.
The tool holder taper and size determine the rigidity and accuracy of machining. Tool holder tapers include: PSC Polygonal, HSK, BT, CAT, and NMTB.
Nikken’s taper characteristics:
- Nickel Chrome 4150 alloy
- AT3 taper or better, 56 to 58 HRc
- Traverse Ground Taper
- Inspected by Prussian Blue oil method
Greater rigidity and higher accuracy allow for more aggressive material removal and part precision. So, Nikken provides the most accurate and precise collet chucks in the industry (guaranteed runout within .0002”). Additionally, Nikken milling chucks are the strongest clamping tool holder in the world with over 3500 ft. lbs of gripping force.
QUALITY TOOL HOLDERS FOR EVERY APPLICATION
Lyndex-Nikken has a wide range of quality tool holders to meet the most stringent specifications for any application.
HIGH-PERFORMANCE ADVANCED TOOL HOLDERS
Tool holders that have innovative designs and technologies that enhance machining performance, precision, and efficiency are advanced toolholders. They offer additional capabilities, above what standard tool holders offer, to meet the demands of modern machining processes. Lyndex-Nikken advanced tool holders help manufacturers stay competitive in today’s demanding manufacturing environment.
SK Collet Chucks: Achieve high precision for optimal machine tool performance due to a titanium nitride (TiN) bearing nut that improves accuracy and gripping force, narrow body that provides better clearance, and taper angle that provides increased gripping power. SK collet chucks are ideal for all applications including milling, drilling, reaming, thread milling and tapping.
Multi Lock Milling Chucks: Nikken invented the milling chuck in 1963, and today the Multi Lock Milling Chuck is still the most reliable and powerful toolholder available. Multi Lock milling chucks feature multi-roller bearings and a heavy-duty nut for more gripping power. Additionally, spiral coolant slots project coolant at 2 degrees which assures high pressure and volume of cooling during high-speed operations. Milling chucks offer a tremendous increase in performance over-end mill holders.
VC Collet Chucks: Due to the TiN bearing nut reducing friction, VC collet chucks hold high runout accuracy within 3 microns at 4 times diameter. This produces better stability and improves surface finish and cutting tool life. Ideal for high-speed machining, thread milling, and ultra-precision reaming, VC collet chucks are designed with a thick wall design of the holder body that improves cutting rigidity and increases dampening. Additionally, an 8-degree internal taper collet provides greater accuracy and clamping capability – double the gripping power of ER collet chucks.
MMC Mini-Mini Collet Chucks: Featuring a slim and compact body for precision machining with small diameter tools (up to 0.5”), the MMC collet chuck is an ideal tool holder for high-speed, high precision machining applications where clearance is needed such as die mold, aerospace, and medical parts. The MMC is precision ground and pre-balanced to 30,000 RPM at G2.5 runout accuracy of 3 microns at 4 times the diameter. An internal draw-in collet clamping mechanism (no collet nut required) results in strong, high-precision gripping from the front nose.
Shrink Fit Holders: Extreme gripping and being pre-balanced for up to 25,000 RPM makes shrink fit holders ideal for high-speed applications. Additionally, due to their slim design, shrink fit holders work well for areas where clearance is an issue. Using shrink fit holders will result in excellent surface finish, and will increase cutting tool life, material removal rate, and workpiece accuracy.
STANDARD TOOL HOLDERS
Standard tool holders hold cutting tools securely in a machine tool and are standardized based on industry standards. Lyndex-Nikken standard tool holders include:
ER Collet Chucks
Known for a wide collet design to provide the most collapsibility (range of 1mm), ER collet chucks provide a continuous gripping range without gaps enabling it to be used in a wide range of applications. The wide collapsible range is made possible by the 16-degree ta per angle. However, the tradeoff is reduced gripping force compared to collets with a slower taper angle. Gripping force can be increased by using a bearing nut. This reduces friction between the nut and the top of the collet significantly increasing linear pressure under the same amount of applied torque while decreasing the tendency to twist and distort the collet. Comes in ER8 collet chuck, ER11 collet chuck, ER16 collet chuck, ER20 collet chuck, ER25 collet chuck, ER32 collet chuck, ER40 collet chuck, ER50 collet chuck, and can hold cutting tools between 1/32nd to 1”.End Mill Holders
The most commonly used holder in the world for drilling and milling is also the oldest tool holder design from 1800’s that provides a very strong grip. End mill holders require a flat on your tool as well as on size tool holder and cutting tool.Shell Mill Holders
Designed to hold shell mills and used only for facing, shell mill holders require a shell mill to be mounted on, and pilot size and shell mill bore must match.Tap Holders
Designed to hold tap collets only.TG Collet Chucks
Known for their single angle tight 8-degree taper, comes in TG25, TG50, TG75, TG100 and TG150, and can told tools between 3/64th to 1.5”.DA Collet Chucks
Gets the name DA from Dual Angle, narrow design allows for tool clearance, comes in 300, 200, 1 00, 180 DA, and can hold cutting tools between 3/64th to 3/4”.Stub Mill Holders
Stub mill holders are designed to hold slitting saws or a group of slitting saws only.Retention Knobs (Pull Studs)
Retention knobs are threaded into the taper end of the tool holder. The machine spindle has a gripper that grabs the pull stud to retain the tool holder in the spindle. Various retention knob designs are used based on the spindle design. One exception for pull stud retention is HSK taper tool holders which have a hollow taper design. In this case, the machine spindle design has a gripping system that inserts fingers into the hollow taper and expands outward to retain the tool holder into the spindle.Jacobs Taper Adapters
Designed to convert the taper of a machine spindle to accommodate a Jacobs taper drill chuck, Jacobs taper adapters allow the use of standard drill chucks with different machines without the need for a dedicated spindle or tailstock.Morse Taper Adapters
These allow machinists to use tools with different Morse Taper sizes on a particular machine without changing the entire spindle.
