BatchMach Precision supports prototype and production orders for small precision components and slender shafts. We assess part geometry, material requirements, and order quantities to plan machining, with critical tolerances and required documentation clarified during quotation.
Mating diameters, shoulder locations, and threaded connections often need to be checked in the actual assembly. We machine samples to your specified materials and drawings, with no minimum order quantity, so you can order what testing requires. Our free DFM review helps identify challenging features and tolerance requirements that may increase machining costs, supporting design revisions before production.
Submit Your DrawingsOnce the design is approved, consistent delivery becomes a purchasing priority. We work to the agreed drawing revision, material grade, and inspection requirements, focusing quality checks on dimensions that affect assembly. First article inspection reports and material certificates are available as agreed. Design or material changes on repeat orders are reviewed for their effect on machining, pricing, and lead time.

From slender shafts and precision pins to miniature threaded fittings, material selection affects part performance, machining efficiency, and cost. We help you select suitable grades based on mechanical loads, corrosion exposure, operating temperature, and drawing requirements.
Stainless steel suits precision shafts, valve components, nozzles, and fittings requiring corrosion resistance. Grade 303 offers easier machining, while 316L provides greater resistance to chloride exposure. For components requiring higher strength, 17-4PH offers a heat-treatable option.
Common Grades:
We offer surface finishing options for Swiss-machined shafts, pins, bushings, fittings, and threaded components. Each process is selected around the material, operating environment, and drawing requirements, with finishing allowances considered for mating diameters, threads, and small bores.
Parts are cleaned and deburred while retaining their natural machining marks. A practical choice for internal components and precision mating features where the specified machined finish meets the application requirements.
Removes free iron contamination from stainless steel surfaces to support corrosion resistance without adding a deposited coating. Suitable for precision fittings, instrument components, and stainless steel fasteners.
Removes a controlled amount of surface material to reduce microscopic peaks and improve surface smoothness. Suitable for stainless steel components requiring cleaner surfaces, with material removal accounted for on critical dimensions.
Creates a protective oxide layer on aluminum components, with clear or dyed finishes available. Suitable for aluminum spacers, sleeves, and small housings, with coating growth considered for threads and mating surfaces.
Provides a relatively uniform nickel-phosphorus coating for corrosion protection and wear performance. Suitable for stepped shafts, bushings, and fittings, with coating thickness specified to suit the required fit.
Adds a protective zinc coating to steel components to help resist corrosion. A practical option for threaded fasteners, studs, and general mechanical hardware, with plating buildup considered on functional features.
Produces a thin black conversion layer on steel parts with minimal dimensional change. Suitable for pins, shafts, and threaded components; supplementary oil or wax improves corrosion protection.
Reduces visible machining marks and improves the appearance of selected accessible surfaces. Polishing areas and finish requirements are defined around the part’s geometry, while precision edges and mating features receive controlled treatment.
Small components often determine how an assembly locates, moves, connects, or seals. BatchMach Precision provides custom Swiss machining for these functional parts, with material specifications, critical dimensions, and inspection requirements defined around your drawings and application.
Instrument mechanisms often combine slender shafts, small bushings, and threaded adapters within limited space. Smooth mating surfaces and carefully finished edges matter during assembly and operation. We review these features alongside the specified material grade, surface treatment, and documentation requirements before machining.
Sensor sleeves, actuator pins, and small valve components need consistent dimensions across production batches. Shoulder locations establish assembly positions, while grooves and mating diameters affect retention and fit. Our drawing review identifies these functional features so machining and inspection address the requirements that matter to your assembly.
For connector pins, contact bodies, and threaded connector sleeves, plating can change the final mating dimensions. Specifying the base material, coating thickness, and finished dimensions together helps establish suitable machining allowances. We also review small bores, thread entries, and edge conditions that could interfere with insertion or assembly.
A pivot pin in a gripper and a locating pin in an assembly fixture perform different jobs. One must accommodate movement; the other must establish position. Miniature shafts, guide bushings, and stepped pins are assessed against their intended fit, with attention to bearing surfaces, alignment, and any specified wear-resistant treatment.
Small spacers, precision bushings, instrument shafts, and threaded fittings require clear control of drawing revisions and material conditions. BatchMach Precision reviews machining requirements and inspection scope at quotation, with first article inspection reports and material certificates available to support the agreed acceptance process.
Internal burrs and poorly finished sealing surfaces can affect how a valve or fitting performs. For valve stems, plungers, small nozzle bodies, and threaded fittings, we review intersecting passages, sealing grooves, and mating surfaces together. Drawings should identify the required edge condition and surface finish at these functional locations.
Meeting a diameter tolerance alone does not ensure a smooth assembly. Misalignment, local distortion, and burrs can also affect performance. BatchMach Precision plans workpiece support, cutting sequences, edge finishing, and dimensional verification around the functional features specified on your drawings.
Machining a small-diameter section reduces its local stiffness, which affects subsequent grooving, drilling, and turning operations. We plan the sequence around guide bushing position, bar extension, and stepped diameters. Keeping the unsupported cutting length short helps reduce deflection and control the risk of diameter taper and chatter marks.
Progressive dimensional changes can indicate tool wear, changing cutting loads, or temperature variation. We establish finishing allowances according to material and geometry, then assess tool condition through dimensional trends, chip formation, and surface appearance. Cutting parameters or tools are adjusted as needed, with particular attention to cutting forces and heat buildup in thin walls and slender sections.
Burrs in cross-holes, thread entries, and narrow grooves can interfere with assembly, sliding contact, or fluid passages. We identify these locations during process review and plan appropriate deburring and inspection methods. Chamfers and radii on sealing edges, locating shoulders, and small grooves follow drawing requirements to avoid removing material that is needed for fit or function.
Clamping conditions and measurement force can influence readings on slender shafts and thin-walled sleeves. We select inspection methods around the drawing datums, assess dimensional changes after unclamping where deformation is a concern, and verify parts in the specified free or restrained state. Suitable dimensions and geometric features can be inspected using ZEISS and Hexagon CMMs.
BatchMach Precision plans inspection around your drawing tolerances, functional surfaces, and documentation requirements. Material checks, first article verification, production inspections, and final review help confirm that your parts meet the agreed acceptance criteria.
/01
Before machining, we confirm the drawing revision, material grade, and specified supply condition. Critical dimensions, thread requirements, surface treatments, and requested certificates are reviewed together so purchasing, production, and inspection work to the same requirements.
/02
Critical features are checked during production to identify dimensional changes as the run progresses. Inspection frequency is planned around tolerance requirements, order quantity, and machining conditions. When results indicate drift, the affected operation is reviewed and subsequent parts are verified after adjustment.
/03
Completed parts are reviewed against the agreed inspection scope, including dimensions affected by any specified finishing operations. Surface condition, accessible burr locations, thread entries, and part identification are checked before release. First article inspection reports and material certificates are available as agreed to support incoming inspection and acceptance.
