Applications

The parts our machines are configured to produce — from bar-fed shafts and fittings to valve, automotive, instrument and polygon components.

APPLICATIONS

Typical Parts for SIPENG CNC Machines

Our turning machines, automation and tooling solutions are configured around the actual part — its geometry, material, tolerance, production volume and cycle-time target. Select an application below to explore the most suitable machining approach.

Shafts & Pins
Shafts & Pins

Stepped shafts, pins, axles and rollers — Swiss-type and slant-bed CNC lathes with bar feeders produce long, slender parts with excellent concentricity and consistent accuracy.

Tolerance ±0.005 mmSteel · Stainless · Brass

Bushings & Sleeves
Bushings & Sleeves

Thin-walled bushings, sleeves and spacers require consistent wall thickness and reliable roundness. Gang-type CNC lathes provide short cycle times for high-volume production.

Fittings & Connectors
Fittings & Connectors

Hydraulic and pneumatic fittings, threaded connectors and nipples — threads, polygon flats and chamfers completed in a single setup.

Valves & Hydraulic Parts
Valves & Hydraulic Parts

Valve bodies, spools, seats and hydraulic components — CNC turning and turn-mill centers complete turning, drilling and milling operations in a single setup.

Automotive Components
Automotive Components

High-volume automotive components — including shafts, bushings, gear blanks and sensor rings — produced in automated machining cells with bar feeding and automatic part handling.

Electrical & Electronic Components
Electrical & Electronic Components

Connectors, insulators, sensor housings and miniature precision parts — Swiss-type CNC lathes provide the accuracy and repeatability required for small-diameter electronic components.

Precision Instruments & High-Precision Components
Precision Instruments & High-Precision Components

Sensor housings, precision shafts, instrument components and miniature high-accuracy parts — tight tolerances, fine geometry and stable repeatability on precision turning machines.

Polygon Parts
Polygon Parts

Squares, hexes, flats and polygon profiles — polygon turning machines generate straight-faced profiles by rotary cutting, far faster than milling.
