Townsend tooling sets, tool holders and motion cams

Factory tooling sets from Townsend include precision cutting tools, tool holders, cut cams and drill cams engineered for secondary operations. Ground cam profiles deliver repeatable tool feed velocity, ensuring tight tolerances across extended production manufacturing runs.

Profiled cut cams and drill cams featuring hardened precision drive tracks
Rigid tool holders with micrometer screw adjustment for fast offset setting
Precision gripping jaws and collet adapters for concentric blank holding
Part ejector pins and scrap strippers with wear-resistant surface treatment

Townsend replacement spindles, collets and jaw assemblies

Townsend replacement spindles are manufactured in plain and high-speed collet configurations. Built with preloaded precision angular contact bearings, these spindle units maintain minimal runout and dynamic balance during multi-shift secondary machining operations.

High speed collet spindles engineered for smooth operation reaching 2800 RPM
Jaw spindle assemblies built with anti-friction tool bar sliding guides
Spring collets provide firm blank clamping without marking finished diameters
Spindle labyrinth seals shield internal bearings from metal chips and coolant

Townsend feed hoppers, transfer fingers and back-rest housings

Townsend automation units include hopper feeders, magazine feeds, pick-off transfer fingers and back-rest housing lever assemblies. These units orient and transfer blanks into the tooling zone in fractions of a second, enabling smooth high-volume automatic production.

Hopper feeder assemblies feature adjustable blades for steady blank metering
Transfer finger assemblies provide secure part pickup and delivery to collet
Back rest housing jaw lever assemblies maintain accurate longitudinal stops
Precision gear train components maintain synchronization across cycles

Townsend Machines and H.P. Townsend industrial manufacturing equipment

The H.P. Townsend Manufacturing Company, marketing equipment under the Townsend Machines brand name, has developed automatic second operation metal-cutting machines since 1910. The manufacturing facility is located in New Britain, Connecticut, USA.

Townsend machines perform finishing cutting operations on blanks produced by cold heading, stamping or turning.

Townsend equipment coordinates secondary forming, slotting, drilling, milling, flattening and tapping within continuous automatic cycles.

The machinery is widely utilized in the manufacturing of automotive fittings, plumbing hardware, electrical contact pins and specialized mechanical fasteners requiring tight dimensional tolerances.

Positive mechanical cam kinematics and automatic blank feeding

The core technical foundation of Townsend Machines rests on positive mechanical cam drives and rigid linkages.

All functional movements including blank feeding, collet clamping, tool feed and finished part ejection are synchronized from a central camshaft, eliminating reliance on auxiliary electronic timers or complex circuitry.

Automated blank delivery is achieved through hopper assemblies and magazine feeds. Individual workpieces are oriented, picked up by transfer fingers and positioned into the collet chuck within fractions of a second.

Integrated mechanical interlocks prevent tool engagement if a blank is misaligned, protecting precision tooling from damage.

Machine variations: High Speed, No. 2 and No. 3 models

The Townsend Machines portfolio provides three standardized machine frames tailored for different manufacturing requirements. The High Speed model reaches production speeds up to 2400 cycles per hour on blanks up to 19 mm (3/4 inch) in diameter. Model No.

2 serves as a versatile machine for workpieces up to 1/2 inch in diameter and 3 inches in length.

For heavy workpieces, Townsend manufactures Model No. 3 built with a rigid frame weighing 1200 lbs. This model accommodates parts up to 7/8 inch (22.2 mm) in diameter and 5 inches (127 mm) long.

Each model variation integrates a precision ball bearing spindle operating at continuous working speeds up to 2800 RPM.

Tooling sets, precision tool holders and ground feed cams

Standard tooling sets from Townsend are engineered for specific workpiece profiles.

A complete tooling set includes micrometer-adjustable tool holders, ground cutting tools, specialized cut cams and drill cams, alongside hopper blades, pick-off fingers and knock-off wheels for automatic workpiece transfer.

Cam profiles are machined from alloy tool steels with deep induction hardening and precision track grinding. This delivers controlled tool penetration, smooth cutter entry and rapid retract kinematics.

Modular tooling assemblies allow machine operators to execute quick tooling changeovers between production runs with minimal downtime.

Spindle assemblies, collets and back-rest housings

To preserve machining precision across continuous multi-shift production, Townsend manufactures interchangeable spindle units. Options include plain spindles and high-speed collet spindles.

Spindle assemblies utilize preloaded angular contact ball bearings that maintain minimal runout during heavy milling and threading passes.

Back-rest housing units incorporate anti-friction tool bar guides and mechanical jaw lever mechanisms. These assemblies provide rigid longitudinal support for blanks during end milling and center drilling.

Spindle labyrinth seals shield bearing tracks from fine metal chips, abrasive debris and cooling fluids.

Equipment identification and part specification by factory nameplate

Accurate specification of replacement parts and tooling for Townsend Machines and The H.P. Townsend Manufacturing Co. is determined by the machine serial number on the factory nameplate.

The nameplate identifies the machine model size, camshaft assembly number, spindle configuration and gear train ratios.

When ordering replacement cams, hopper blades or collets, providing a workpiece drawing with blank dimensions, thread specifications or slot geometries ensures correct matching.

Factory-manufactured components fit original mounting interfaces without requiring secondary manual machining or fitting on site.
