JBO: Automatic Gauging for Internal Threads

Presenting the new Automatic Thread Gauge from JBO – a compact and reliable inspection system for checking the threads of nuts, implants, and other small parts with internal threads – ideal for use in production, quality assurance, or incoming goods inspection.

The device enables measurement of thread depth and inspection of thread accuracy in an automated testing process. Thanks to a motor-driven plug gauge with a quick-change coupling, internal threads can be checked precisely and efficiently – even in series production

Advantages at a glance:

Reliable measurement results (resolution 0.01 mm)
Time savings through automated operation
Easy handling with interchangeable plug gauge
Two measuring modes: Minimum thread depth and measurement
of thread depth with a defined range (from/to)
Digital display and acoustic signal for quick evaluation
Software control for individual test parameters
USB interface for data transfer

Ideal for:

Series inspection of nuts, implants, and other small parts with internal threads
Quality assurance according to standards
Rapid inspection in incoming goods or production environments

HORN: New System for Grooving and Parting Off

S234 – this is the name of the newly developed parting system that Horn has developed especially for large grooving depths. The double-edged system enables a maximum depth of cut of 33 mm (1.300″). This means that diameters up to 65 mm (2.560″) can be parted off reliably and economically. The combination of high grooving depths, rigid clamping, high-performance chip breaker geometry and internal cooling makes the system extremely attractive in terms of price/performance ratio.

The inserts are available in cutting widths of 2 mm (0.079”) and 3 mm (0.118″). The corner radii are 0.2 mm (0.008″) and 0.3 mm (0.012”) respectively. The sintered EN geometry ensures reliable chip removal. Depending on the material to be machined, the inserts are available in AS45 and IG65 grades. Square shank holders in sizes 20 mm x 20 mm (0.787 x 0.787″) and 25 mm x 25 mm (0.984 x 0.984″) ensure stable clamping. Horn also offers reinforced grooving blades and tool holders for the modular parting and grooving system. All types are equipped with internal coolant supply.

JBO : SHARK Thread Milling Cutters

Long Tool Life, Short Processing Time and Excellent Surface Quality – three advantages of solid carbide thread milling cutters from Johs. Boss GmbH & Co. KG Präzisionswerkzeugfabrik, Germany. Available in a wide range of Thread Milling Cutters, Drill Thread Milling Cutters and Indexable Thread Milling Cutters including specials.

The SHARK high-performance Thread Milling Cutters from JBO offer precise thread machining – complemented by the G-thread range within the GFT series (solid carbide three-profile thread milling cutters).

General Advantages of Thread Milling

Threads to different tolerance classes can be produced with same cutter
Tool breakage does not necessarily entail scrapping of the workpiece
Less power needed for cutting internal threads
Short machining times due to high cutting speeds
Excellent thread surface finish
Short chips, hence no chip problems
Right and left hand threads can be produced in blind or through holes by the same cutter
Low cutting forces enable threads to be cut in thin wall workpieces
Cutting speeds and feeds can be matched individually to workpiece material
No change of cutter spindle direction of rotation required
No special tapping chucks required, standard chucks suffice
Threads can be cut to exact depth
Threads can be cut down to near bottom of blind holes
Start of thread accurately determined by NC programme

HORN: New Six-Edged Inserts with New Grooving Depth

Six-Edged Inserts with New Grooving Depth

With the 66T grooving system, Horn is expanding its tool portfolio in the area of six-edged indexable inserts. With six cutting edges, the insert offers an attractive price per cutting edge. The maximum grooving depth is 9.5 mm (0.374″). This is around 4 mm (0.157″) more than the sister system, 64T. Depending on the application, Horn offers inserts with two geometries and a version without geometry. The available geometries ensure reliable chip removal during machining. The IG65 carbide grade is used for machining stainless materials and difficult-to-cut materials. For general steels, Horn recommends the EG55 carbide grade for the 66T system.

The available cutting widths are 2.5 mm (0.098″) and 3 mm (0.118″). The corner radius is 0.2 mm (0.008″). The 1A geometry is suitable for pure groove turning operations, while the DL geometry is suitable for longitudinal turning in addition to grooving. The DL geometry is therefore also available with a corner radius of 0.4 mm (0.016″). The effective chip control of the chip breaking geometries ensures high surface quality on the groove flanks and the straight main cutting edge produces a cleanly finished base. Designed as neutral grooving inserts, they can be clamped in square shanks with internal cooling on both the left and the right side. Holder dimensions are 20 x 20 mm (0.787 x 0.787″) and 25 x 25 mm (0.984 x 0.984″). A clamping screw fixes the grooving insert precisely and securely in the central insert seat. Horn also offers type 220 clamping cassettes for the modular holder system.

HORN at EMO Hannover 2025

HORN at EMO Hannover 2025 (Hall 5, Stand A32)

Since its inception in 1975, EMO has stood worldwide for innovation, internationality, inspiration and the future of metalworking. In 2025, the exhibition will celebrate its 50th anniversary.

As the world’s leading trade fair for production technology, EMO in Hanover offers a unique platform every two to four years under the motto “Innovate Manufacturing” to make international contacts, open up new business opportunities and gain a comprehensive overview of the industry’s worldwide offerings. The last event in 2023 attracted over 92,000 visitors from 140 countries and around 1,850 exhibitors to this industry highlight.

HORN will be showcasing pure machining on 580 square meters in Hanover. Four machines, four exciting components, a wide variety of tool solutions – live in action and cutting chips throughout the entire exhibition. The following will be on display: the DMU65mB from DMG, an Index G220, a Citizen L12 and a GROB G150. In addition, we will be displaying numerous exhibits and tool solutions and presenting our innovations for 2025.

Markus Horn, Managing Director of Paul Horn GmbH: “I am convinced that a visit to EMO will be worthwhile for our customers and interested parties – we will be presenting machining at the highest level. On the four machines, we will be demonstrating the topics of finishing, machining lead-free materials, aluminium machining with rotating PCD tools and technology components with ” ” numerous turning operations. Horn continues: “In my opinion, the best results are achieved through dialogue, and EMO offers the ideal platform for this. Visit us in Hall 5, Stand A32.”

New Mini System with Sintered I Geometry

In addition to live machining, Horn will be presenting numerous innovations. Among them is the Mini system with sintered chip breaker geometry, which was unveiled for the first time at the Horn Technology Days in May 2025. The sintered I-geometry is particularly aimed at machining materials with poor chip formation properties. It is suitable for copy turning, longitudinal turning, back turning and facing. Especially with shallow depths of cut in steel and stainless steels, the tool system with this geometry demonstrates its strengths in chip control. It leads to higher process stability and longer tool life. When developing the I-geometry, HORN also took into account the machining of lead-free materials. As these materials will pose a challenge in the future due to their inferior chip formation, the tool manufacturer offers inserts with small corner radii starting from 0.05 mm for small lateral infeeds. Corner radii from 0.05 mm to 0.2 mm are available from stock.
