Product Description
The SZGH-36Z is a 2-axis slant bed CNC lathe manufactured by Shenzhen Guanhong Technology Co., Ltd. (SZGHTECH). It shares the core mechanical platform of the 36-series — 35mm maximum bar diameter, ±0.01mm machining accuracy, Ra 1.6μm surface roughness, 1,800kg machine weight, and the self-developed SZGH CNC control system — in the Z-type variant configuration. The Z designation indicates a different control panel layout and interface arrangement compared to the J-type, offering an alternative ergonomic and operational setup within the same mechanical specification. It is suitable for batch production of copper, iron, aluminum, and stainless steel bars within 35mm, and for replacing hard-rail and hydraulic automatic lathes in workshops upgrading to automated precision turning.

The SZGH-36Z shares every core mechanical specification with the SZGH-36J: the same 1,800kg anti-deformation cast base, the same 4kW spindle, the same Harbin two-axis angular contact bearings, the same H-class linear guide rails, and the same SZGH control system. The Z-type designation refers to a different control panel layout and interface arrangement — suited to operators and workshop configurations where the panel positioning or control access orientation of the Z variant is a better ergonomic match. Both models deliver identical machining performance, accuracy, and reliability.
For procurement managers building a standardised machine fleet, the 36Z and 36J can be deployed on the same production line — operators trained on one can work on both, maintenance procedures are interchangeable, and spare parts are shared across the platform.
The machine base is cast from high-grade cast iron using SZGHTECH's patented anti-deformation casting process. At 1,800kg, the base provides the inertial mass needed to suppress vibration during aggressive cutting of 30–35mm stainless steel bar stock and to resist thermal deformation during extended production shifts. Dimensional consistency across a 1,000-piece batch on the SZGH-36Z is governed by the machine's structural stability, not by mid-run operator re-measurement and offset adjustments.
The 30° inclined bed keeps chips clear of the guide rail surfaces throughout the cutting cycle. Unlike flat-bed lathes where chips accumulate on the bed ways and require periodic shutdown for cleaning, the SZGH-36Z's slant geometry lets chips fall directly into the chip conveyor zone by gravity. The result is longer guide rail life, a cleaner cutting environment, and reduced maintenance downtime — relevant for factories running multi-shift production schedules.
The 4kW variable-frequency spindle motor, paired with two-axis Harbin high-speed angular contact fusion bearings (dynamically balanced at the factory), delivers consistent torque across the 500–3,500rpm working range. The Harbin bearing specification supports both the high radial loads generated during heavy facing cuts and the precise concentricity required for fine finishing passes on the same part — without bearing adjustment between operations.
The SZGH-36Z is equipped with SZGHTECH's self-developed CNC controller, the same platform used across all SZGH machine tool models. Key advantages for international buyers:
Standard ISO G-code: Compatible with Fanuc 0i-T programming conventions (G71, G72, G73, G76, G70 cycles fully supported). Existing programs from Fanuc-controlled lathes migrate with minor format edits.
English-language interface: Reduces operator learning curve in non-Chinese-speaking factories.
Single-source engineering: The manufacturer who built the machine also wrote the firmware — no third-party controller vendor in the support chain.
Remote diagnostics: SZGHTECH engineers can access the controller remotely via VPN for real-time fault diagnosis, reducing downtime resolution time.
Like all 36-series machines, the SZGH-36Z is engineered as a drop-in replacement for aging hard-rail CNC lathes and hydraulic automatic lathes processing small parts in the 25–35mm diameter range. The 1,750 × 1,400mm footprint matches the floor space of most installed hard-rail lathes, and the SZGH controller's G-code compatibility means existing NC programs require only minor edits to run. Customers typically achieve full production output within 3–5 days of machine delivery.
The SZGH-36Z processes copper, iron, aluminum, and stainless steel (304/316) bar stock up to 35mm diameter, and open-forged disk blanks up to Ø50mm. With hydraulic chuck, it supports single-piece production of parts within Ø250mm (max Ø300mm).
Shafts, pins, valve stems, bearing races, wheel fasteners — medium-volume automotive hardware turning where ±0.01mm repeatability is required across thousands of identical parts per production shift.
Valve bodies, union fittings, cylinder end caps, nipples — the 35mm bar capacity covers the standard range of hydraulic fitting stock in stainless steel, brass, and carbon steel.
Bolts, studs, threaded inserts, lock nuts, coupling nuts — high-volume thread turning and grooving where consistent pitch diameter and surface finish across large batches determine product quality.
Terminal pins, copper connectors, aluminum spacers, sensor housings — small precision turned parts where the Ra 1.6 surface finish and ±0.01mm accuracy are production requirements rather than targets.
Any application currently running on a hard-rail or hydraulic automatic lathe with bar stock up to 35mm — the SZGH-36Z is designed specifically as the upgrade path for this installed base.

Both models share the same mechanical specifications: 35mm bar capacity, 1,800kg machine weight, 4kW spindle, Harbin angular contact bearings, H-class linear guide rails, ±0.01mm accuracy, and the SZGH control system. The difference is in the control panel layout and interface configuration — the Z-type and J-type designations indicate different ergonomic panel arrangements suited to different operator preferences or workshop setups. Machining performance and accuracy are identical between the two variants.
The SZGH-36Z handles bar stock from small diameters up to a maximum of 35mm. For disk-type forged blanks (pellet feeding), the maximum is Ø50mm standard. With a hydraulic chuck installed, it supports single-piece production of parts up to Ø250mm (max Ø300mm).
Yes — this is the primary application. The SZGH-36Z is designed to replace hard-rail and hydraulic automatic lathes processing parts within 35mm diameter. The footprint matches most existing hard-rail lathe installations. The SZGH controller's ISO G-code compatibility means existing NC programs can be migrated with minor edits, and most customers achieve full production output within 3–5 days of machine delivery.
Yes. The standard maximum single-side cutting depth in stainless steel is 2mm (max 3mm). Recommended parameters: carbide inserts with positive rake geometry, cutting speed 80–120 m/min, continuous coolant flood. The 1,800kg anti-deformation base effectively absorbs the elevated cutting forces associated with stainless steel turning.
Yes. The machine is compatible with external automatic bar feeders for stock diameters from 8mm to 35mm. With bar feeder integration and a programmed SZGH controller cycle, one operator can supervise 3–5 machines simultaneously — the standard labor-reduction configuration for batch production environments.
The SZGH controller uses standard ISO G-code compatible with Fanuc 0i-T conventions. All standard turning cycles — G71 (outer roughing), G72 (face roughing), G73 (pattern repeat), G76 (multi-pass threading), G70 (finishing) — are supported. Programs from Fanuc-controlled machines require only minor format adjustments. SZGHTECH provides a bilingual English/Chinese programming manual and remote support during the commissioning period.
SZGHTECH provides a 12-month warranty covering all mechanical and electrical components, excluding consumables (cutting inserts, hydraulic oil, seals). Replacement parts are shipped at no charge during the warranty period. Remote diagnostic support via WhatsApp video call is available 24/5. Customers in countries with SZGH agent networks (USA, Turkey, Romania, Russia, Egypt, Thailand, Mexico) have access to local in-country service.
Standard production lead time is 20–35 working days from receipt of deposit. One 20-foot container fits 2–3 units. The machine ships in a wooden export crate with anti-rust treatment and moisture barrier protection.
